6 Major Reasons to Adopt Swift For iOS App Development

Have you decided to develop an iOS application? You might face some of the challenges while choosing a right programming language for building. It’s obvious as choosing a right and suitable language is the most important step that can make or break your application.

 

With the inception of Swift, a lot of developers have started using this high-end language that is a general purpose compiled and multi-paradigm programming language. Developed by Apple for iOS developers to build codes for iOS, WatchOS, MacOS, Linux, and TVOS.

 

In addition to this, Swift was developed using an approach that is both modern and is ease of use to develop software patterns and enhance the performance of an application. Many of you all are aware of this language that is new yet powerful.

If you are planning to develop an iOS application, opting for Swift is the best choice for you as it comes with enormous features to make you amaze.

 

Let’s Have a Look at the Different Reasons to Adopt Swift for Developing iOS Apps

 

Open Source & Gaining Popularity Instantly

Swift is the most powerful programming language over other programming languages. Being an open source language, it has gained much popularity in the market as it makes it immediately accessible and less costly for startup companies.

 

As per the studies, open source software/languages mutually help business owners to save approximately $60 billion per year. The language is obtainable on Linux and work is being done to bring Swift to Windows.

 

Moreover, the language shows an excellent potentiality and growing rapidly. It was a monopoly for Objective-C to develop native iOS application until 2014; however, Swift has brought an end to that era.

 

A Lot Easier to Read as well as Write

One of the best things about Swift programming language is that it drops practices like ending with semicolons or using digression to surround conditional expressions inside if/else statements.

 

Further, the language’s method and function calls make use of the benchmark convention of a comma-separated list of parameters. With lesser code, it helps you to get the same results as per the syntax requirements. The results will be clear, simpler, and more expressive language.

 

The readability of this language has made it easy for programmers from JavaScript, Java, Python, C++ and C# to adopt Swift into their tool chain.

 

A Highly Innovative Approach

It’s true that the Swift is a new language and it is the main reason why you should start learning it right now. Mainly designed to make app development more interactive and approachable, Swift has made app developing more accessible for all those, who are developing their own applications.

 

This is the reason why Swift will be widely used. We can consider this programming language of the future. So, it is advisable for you to adopt the principle – the newer – the better. You should be the one, who stepped into the future in the front row.

 

Well, it is right that any other innovation, Swift needs some adjustments and learning. It is a good option that you make use of something that is popular; however, it is way better to be the one, who’s engaged in the process of enhancements and innovations.

 

Safer and A Lot Easier to Maintain

As we all know that safety is the most important aspect when it comes to mobile applications. In this cutthroat market, a startup should concentrate on developing a highly secure mobile application.

 

In addition to this, if the application is easy to maintain, it is a boon really. Swift is a highly amazing language that delivers both benefits at the same time. Whether it is the way it handles bugs or calls the pointer variables, it is well-known for producing safer applications than Objective-C.

 

Apart from this, Swift is highly easier language to maintain and it doesn’t have any kind of legacy code to deal with. This language doesn’t have any dependencies like Objective-C. So, opting for Swift for building an iOS application is a right option because of its safe feature.

 

Fast Yet Powerful Programming Language

From its beginning, the Swift programming language was mainly developed to be the fast and considered as a powerful. The codes that are written in this language are compatible with the latest hardware and get most out of them.

 

The syntax and standard library of this language ensure that the Swift codes function amazingly. However, the successor of Swift to the languages C and Objective-C, and it includes the primitives of programming like types, operators, and the flow controls.

 

Furthermore, the language also comes with some of the borrowed features, comprising classes, generic, protocols and more from the object-oriented language. It delivers the Cocoa and the Cocoa Touch developers the power of programming that is required to build some powerful quality apps.

 

It is one such programming language, which is mainly built to be something way grand when compared to its predecessors. However, the language is still in its work-in-progress mode, but you should adopt this high-end language because of its new and undiscovered potential that will make it easier to code.

 

Less Code Means Fewer Chances of Errors

As already mentioned that Swift requires less code than other programming languages, the chances of errors will be less. As a functional programming language, Swift is highly popular for supporting passing functions as variables.

 

Thus, you can develop highly generic code that can do a lot of amazing things, decreasing repetition and efforts. Along with this, Swift’s expectable behavior when a null optional variable is used, this is the programming language that triggers a runtime crash.

 

The bang fuels-up the bug-fixing process because of its consistent behavior and it forces users to fix the problem instantly. Hence, the development time will be reduced.

 

Above-mentioned reasons will surely make you ready to adopt Swift for building iOS application. These reasons are enough for any iOS developer to adopt this high-end and powerful programming language that makes development easy.

 

If you want to develop a feature-rich iOS application with requisite features, you can hire an experienced iPhone app development company that has a veteran team of iOS app developers with a specialization in Swift language and other latest tools.

How to Install Xamarin to Microsoft Visual Studio

The announcement of third-party mobile application development platform, Xamarin as open source is buzzing around the .NET developer forums and discussion boards now.

This mobile application development platform can be used integrating with the Visual Studio IDE of Microsoft for free now. There won’t be any trial period to expire or it won’t ask for commercial license to continue in any future. All you would need to have is the latest version of genuine licensed Visual Studio IDE software installed on your computer.

Installation of Xamarin will be executed in three phases. They are,

1. Installation of Java JDK
2. Installation of Android SDK
3. Installation of Xamarin libraries

1. Installation of Java JDK

In this phase the Xamarin installer will download and install the latest version of the Java JDK which is needed for the Android app development.

Java is platform independent and it will be installed with out any intermediator interpreters on Windows.

2. Installation of Android SDK

Installation of Android SDK is the 2nd phase of installing Xamarin to Visual Studio. Android development is all managed by this Android SDK from Google. To develop the android apps with Java, you would need to download and install complete android studio but as we are aiming to develop the android apps using .NET technologies like C# and F#, we only need the core layer, the Android SDK.

installing-android-sdk-platform-6

This android SDK will integrate into the Visual Studio allowing us to develop right from the VS IDE itself. This is another reason why Android SDK don’t need another IDE (android studio) for developer interface coding.

3. Installation of Xamarin libraries

Xamarin acts as intermediator interpreter for .NET technologies C#/F# and Java. The coding conventions of .NET will be translated into Java native coding using the Xamarin libraries. This is the third and last phase of installing Xamarin to Visual Studio IDE.

Let the Xamarin installer install the libraries needed for the integration with Visual Studio.

After installation, open Visual Studio > File > New Project. You would find the Android and iOS project options to continue. Go to Xamarin University and learn how to program with Xamarin on Visual Studio with .NET technologies.

That’s it! Enjoy Android and iOS app development from Visual Studio.

Xamarin is Open Source Now; Available Free for Visual Studio

Xamarin, the third party .NET app development platform for Visual Studio announced as open source platform which now will be available for free for Visual Studio. The Microsoft has acquired this company recently to bring the better and flexible development options for the .NET developers.

 

Xamarin provides the rich mobile development offering that enables developers to build mobile apps using the C# technology to deliver the native mobile app experience on major devices like Android, iOS and Windows Phone. This development add on for Visual Studio had been released as a commercial version by the company before merging into Microsoft. After signing the acquiring contract, Microsoft announced this leading mobile development platform as open source for the commercial license holders of .NET development environment, Visual Studio.

 

Xamarin has 15,000 customers in 120 countries which includes 500 fortune companies and 1.3 individual developers who have taken advantage of this offering.

 

Microsoft has longstanding partnership with Xamarin in building the integration with Visual Studio, Microsoft Azure, Office 365 and Enterprise Mobile Suite to provide developers with an end-to-end workflow for native, secure, app cross platforms.

 

Xamarin-logo

In this regard, Nat Friedman of Xamarin writes in their blog about making Xamarin an open source.

 

On March 18th, 2016, Microsoft’s acquisition of Xamarin officially closed.

 

We love C# and we want every developer to be able to take advantage of the power of .NET in every app, on every device. Being part of Microsoft makes it possible for us to do some incredible things, and today we are announcing several big changes to the way we ship our products.  -Nat Friedman

 

With this announcement, Xamarin will be included in every edition of Visual Studio including free developers edition. With this integrated, an average .NET developer can develop native apps using C# and F# technologies for Android, iOS along with Windows without any app size restrictions.

 

“So we are announcing today that we have contributed the Mono Project to the .NET Foundation, including some previously-proprietary mobile-specific improvements to the Mono runtime. Mono will also be re-released under the MIT License, to enable an even broader set of uses for everyone. In addition, to help clarify users’ rights to Mono under Microsoft patents, Microsoft has issued a broad patent promise for Mono. Miguel has posted more details to the Mono Project blog.

 

These changes to Mono remove all barriers to adopting a modern, performant .NET runtime in any software product, embedded device, or game engine, and open the door to easily integrate C# with apps and games on iOS, Android, Mac, and Windows, as well as PlayStation 4, Xbox One, and any emerging platforms developers want to target in the future

 

But wait, there’s more!

 

In addition to these important steps, we are announcing today our commitment to open source the Xamarin SDKs for Android, iOS, and Mac under the MIT license in the coming months. This includes native API bindings and the basic command-line tools necessary to develop mobile apps. It also includes our popular cross-platform native UI toolkit, Xamarin.Forms.

 

With these changes, .NET is now open source and native on every single device, from mobile to desktop to cloud. This is a proud moment for all of us who have invested years into making .NET the best platform, and we know that this change will make it even easier for developers to invest their own time into building great software in C#.

We look forward to building a true open source community around Xamarin, and eagerly await the first pull requests.” Nat Friedman adds in the Xamarin blog post.

 

The bottom line of this business activity is that the .NET developer can now develop Android and iOS apps on Visual Studio. What are you waiting for? Give your ideas a shape.

Making Notepad Application Using C# in Visual Studio 2013

Notepad is a familiar and famous and basic text editor program that exists on Windows computer with very basic text editing capability.

 

We can make our own notepad application for Windows operating system using C# programming. The programming techniques, code and screenshots used in this tutorial are in compliance with the latest versions of the following tools and technologies. Here they are,

  • C# 5.0
  • Visual Studio 2013
  • .Net Framework 4.5

Let’s get started,

 

Go to File > New > Project > select C# > Windows Forms Application. This creates a new form(Form1) by default in the workspace.

 

Drag and drop the MenuStrip from Toolbox > Menus & Toolbars on to the form. we need to add the MenuItems and Sub-MenuItems in the MenuStrip now.

 

As we are doing a Notepad application here, we’ll add up File and Edit menus. Under File menu, add New, Edit & Save sub-MenuItems and under Edit, add Cut, Copy & Paste sub-MenuItems. This will make the application look like this,

 

adding-file-menu adding-edit-menu

 

In next step, we’ll have to add the TabControl to generate the File > New functionality.

 

Add a TabControl from All Windows Forms tools. By default, it will create a TabControl with two tabPages. This will look something like this,

 

adding-tabcontrol

 

As we have no need of them while using along with MenuStrip, we’ll remove them by Right-Click on tab page > Delete. After deleting both the tabPages, the TabControl will look something like this,

 

after-removing-tabpages

 

The TabControl should not be moved or changing its position with the resizing of the window. So, lets dock it to the form. Select TabControl > Press F4(Properties) > Under Layout > set Dock property to Fill. The resultant form after docking of TabControl will look like this,

 

docking-tabcontrol 

Now, let’s write the purposeful code for the TabControl, i.e., adding a new tab when clicked on File > New.

 

Adding ‘New’ functionality

Double-click on the New from File MenuStrip, it will enable the click event and allows us to add our own code. This will look something like this,

 

enabling-click-event

 

Add the following code in the event handler:

 

TabPage tp = new TabPage("New Document"); //creates a new tab page
RichTextBox rtb = new RichTextBox(); //creates a new richtext box object
rtb.Dock = DockStyle.Fill; //docks rich text box
tp.Controls.Add(rtb); // adds rich text box to the tab page
tabControl1.TabPages.Add(tp); //adds the tab pages to tab control

 

After adding, it will look something like this,

 

private void newToolStripMenuItem_Click(object sender, EventArgs e)
{
    TabPage tp = new TabPage("New Document"); //creates a new tab page
    RichTextBox rtb = new RichTextBox(); //creates a new richtext box object
    rtb.Dock = DockStyle.Fill; //docks rich text box
    tp.Controls.Add(rtb); // adds rich text box to the tab page
    tabControl1.TabPages.Add(tp); //adds the tab pages to tab control
}

 

The purpose of adding the lines in the code is briefly explained in single comments are followed.

 

Adding ‘Edit’ functionality

We are now done with adding a new document for File > New menu option. Let’s also work with the Edit menu options.

 

There available a readymade RichTextBox control available in C#.NET using which we can implement Cut, Copy and Paste options.

 

Now, add this following function in your code,

 

private RichTextBox GetRichTextBox()
{
    RichTextBox rtb = null; //making it initially null
    TabPage tp = tabControl1.SelectedTab; // saves the tab selection status in a tabpage type variable
    if(tp!=null)
      {
        rtb = tp.Controls[0] as RichTextBox; //sets the selected rich text box index as primary
      }
    return rtb;
}

 

Now, double-click on the Cut sub-MenuItem from File > Cut. I will open into its event handler function. Then write GetRichTextBox().Cut() in it.

 

Do the same with Copy and Paste options also. Only the methods Copy(), Paste() will replace Cut() from the above line. Then the resultant code will look like this,

 

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Notepad
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void toolStripMenuItem1_Click(object sender, EventArgs e)
        {

        }
        private RichTextBox GetRichTextBox()
        {
            RichTextBox rtb = null; //making it initially null
            TabPage tp = tabControl1.SelectedTab; // saves the tab selection status in a tabpage type variable
            if(tp!=null)
            {
                rtb = tp.Controls[0] as RichTextBox; //sets the selected rich text box index as primary
            }
            return rtb;
        }
        private void newToolStripMenuItem_Click(object sender, EventArgs e)
        {
            TabPage tp = new TabPage("New Document"); //creates a new tab page
            RichTextBox rtb = new RichTextBox(); //creates a new richtext box object
            rtb.Dock = DockStyle.Fill; //docks rich text box
            tp.Controls.Add(rtb); // adds rich text box to the tab page
            tabControl1.TabPages.Add(tp); //adds the tab pages to tab control
        }

        private void cutToolStripMenuItem_Click(object sender, EventArgs e)
        {
            GetRichTextBox().Cut();
        }

        private void copyToolStripMenuItem_Click(object sender, EventArgs e)
        {
            GetRichTextBox().Copy();
        }

        private void pasteToolStripMenuItem_Click(object sender, EventArgs e)
        {
            GetRichTextBox().Paste();
        }
    }
}

 

We are done with New, Cut, Copy and Paste options so far. We need to work on Open and Save functionalities now.

 

Adding ‘Open’ functionality

To open a file into the rich text box, we need to add a OpenFileDialog() that accepts the file from computer and write the code to insert it in the rich text box that we’ve added previously.

 

Drag and drop the OpenFileDialog()on to the form and then double-click on Open sub-MenuItem from File MenuStrip.  It will open into its event handler function that looks like as shown below,

 

private void openToolStripMenuItem_Click(object sender, EventArgs e)
{

}

 

Now add the following piece of code in the function. After adding, it will look something like this,

 

private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
   Stream myStream;
   if(openFileDialog1.ShowDialog()==System.Windows.Forms.DialogResult.OK)
   {
       if((myStream=openFileDialog1.OpenFile())!=null)
        {
           string filename = openFileDialog1.FileName;//copies the path of the file into a variable
           string readfiletext = File.ReadAllText(filename);//reads all the text from the opened file
           TabPage tp = new TabPage("New Document"); //creates a new tab page
           RichTextBox rtb = new RichTextBox(); //creates a new richtext box object
           rtb.Dock = DockStyle.Fill; //docks rich text box
           tp.Controls.Add(rtb); // adds rich text box to the tab page
           tabControl1.TabPages.Add(tp); //adds the tab pages to tab control
           rtb.Text = readfiletext;
         }         
   }
}

 

Before adding the above code, make sure you have included the following references,

 

using System.Text;
using System.IO;

 

Or else, you would get an error while declaring Stream reference.

 

Run the application and test it by uploading a file. It even accepts XML files when loaded.

 

Adding ‘Save’ functionality

So, we are successfully done adding Open functionality and the only functionality left to work with is the ‘Save’.

 

We need to use the SaveFileDialog on TabPages to achieve this. Just dragging and dropping on the form may not help as it creates TabPages only in runtime.

 

Let’s add it manually.

 

Double-click on the Save sub-MenuItem from File MenuStrip and it opens into its event handler function.

 

Adding the code into it will appear like as shown below,

 

private void saveToolStripMenuItem_Click(object sender, EventArgs e)
{
   SaveFileDialog savefile=new SaveFileDialog();
   savefile.Filter = "*.txt(textfile)|*.txt";
   if(savefile.ShowDialog()==DialogResult.OK)
   {
      rtb.SaveFile(savefile.FileName, RichTextBoxStreamType.PlainText);
   }

}

 

That’s it! We’re done with all the basic functionalities we have added. This is how it looks,

 

final-notepad

 

Now let’s make it look more beautiful

Functionally, we are done with everything. But when executing, it still shows the title as ‘Form1’ with no favicon and opens in s small window. Let’s fix it by customizing!

 

Go to Form1.cs Design > Properties > Change the text from Form1 to anything you would like to display on the title bar. I’d choose to display Notepad.

 

Text: Form1

 

to

 

Text: Notepad

 

Next, let’s change the icon.

 

Under Window Style, set ShowIcon property to True and choose an icon from your computer for Icon property.

 

Changing the icon is done, let’s fix the small window startup.

 

Navigate to Layout properties > Change WindowState from Normal to Maximized. This will open the window maximized when the program is started. Take a look at the following screenshot of how it looks after tweaking.

 

final-notepad

 

Hope I covered all those very basic functionalities for a customized Notepad. Checkout how it works finally:

 

 

Creating the executable package

So, you have developed your own software program. Let’s create a executable package of it so that everyone else can simply install it on their computers and use it.

 

Go to Solution Explorer > Right-click on the project > Publish. Go through the wizard and finish the process of creating a installable file of your project.
