Mobile applications are now a must-have for almost every online business. The latest StatCounter data shows that as many as 56% of online connections are made via mobile devices, which puts them above tablets and computers. What's more, the same source says that 27% of them are iOS devices.

A mobile app can also improve your customer service, apart from increasing your product sales and business visibility. An app ensures the same presentation of products and services every time users access it. Customers can go through the same interface, no matter which page they access.

Here are 7 best programming languages required for iOS app development

1.Swift

Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. and the open-source community. First released in 2014, Swift was developed as a replacement for Apple's earlier programming language Objective-C, as Objective-C had been largely unchanged since the early 1980s and lacked modern language features. Swift works with Apple's Cocoa and Cocoa Touch frameworks, and a key aspect of Swift's design was the ability to interoperate with the huge body of existing Objective-C code developed for Apple products over the previous decades.

Swift can be used to create applications easily and it's also very easy to learn and apply to your project. And you can make improvement on your due to the fact that swift is regularly updated.

2. C#

C# is a general-purpose, multi-paradigm programming language encompassing static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented, and component-oriented programming disciplines.

C# was developed around 2000 by Microsoft as part of its .NET initiative and later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO (ISO/IEC 23270) in 2003. It was designed by Anders Hejlsberg, and its development team is currently led by Mads Torgersen, being one of the programming languages designed for the Common Language Infrastructure (CLI). The most recent version is 9.0, which was released in 2020 in .NET 5.0 and included in Visual Studio 2019 version 16.8.

It is an object-oriented programming language created by Microsoft that runs on the .NET Framework.

C# has roots from the C family, and the language is close to other popular languages like C++ and Java.

The first version was released in year 2002. The latest version, C# 8, was released in September 2019.


3. JAVA


Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let application developers write once, run anywhere (WORA).

Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages.(WIKIPEDIA)

Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.)
-It is one of the most popular programming language in the world
-It is easy to learn and simple to use
It is open-source and free
-It is secure, fast and powerful
-It has a huge community support (tens of millions of developers)

Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs


4. Flutter

Flutter is a comprehensive app Software Development Kit (SDK), including ready-to-use widgets and tools. It was created by Google in 2015 and officially launched in 2017.

Flutter is worth considering, especially if you want to create not only an iOS and Android app but you also plan to create a desktop and web version.

5. React Native

React is a JavaScript library created by Facebook.

React is a tool for building UI components.

Instead of manipulating the browser's DOM directly, React creates a virtual DOM in memory, where it does all the necessary manipulating, before making the changes in the browser DOM.

Current version of React.JS is V16.8.6 (March 2019).

Initial Release to the Public (V0.3.0) was in July 2013.

React.JS was first used in 2011 for Facebook's Newsfeed feature.

Facebook Software Engineer, Jordan Walke, created it.

The create-react-app version 2.0 package was released in October 2018.

6. Kotlin

Kotlin is a modern, trending programming language that was released in 2016 by JetBrains.

It has become very popular since it is compatible with Java (one of the most popular programming languages out there), which means that Java code (and libraries) can be used in Kotlin programs.

This is very easy to learn and you'll have a better advantage if you already know Java.


7. Javascript


JavaScript is the world's most popular programming language.

JavaScript is the programming language of the Web.

JavaScript is easy to learn.

JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions.

No regret for choosing java pl,I am pressing on

@Op,
Is this list according to an order?

Just for more info, C# will require Xamarin Form or Xamarin Native IOS.

And I want to belive that that's the easiest to learn.
