Here are a few programming languages you can adopt for your Native iOS app development

1. Swift

Swift is one of the most popular iOS programming languages across the globe. It is built with the latest safety measures, enhanced performance, and software design patterns. Swift is designed to provide the best services for programming the systems, app development, writing and maintaining correct programs, and ascending to cloud services.

When you write your code with swift, it is safe, fast, and expressive. Safety is one of the essential things in the app development process. Therefore, it is important to write code safely and quickly, notifying the developer’s mistakes before beginning the production. Along with the safety, swift is also fast.

Swift has many features that make the codes easier to read and write. While using swift, the developers are in control. With swift, memory is automatically managed, there is no need to use semicolons, making the codes cleaner. Let’s take a look at some additional features of swift.

  • Generics
  • Multiple return values
  • Practical programming patterns
  • Advance control flow with selected keywords
  • Structure supporting methods and extensions
  • Doesn’t require a separate library to support functionality 


  • It has a simplified syntax
  • It can extend its functions if required
  • Easy to integrate with objective-C
  • It prevents code crushing by error handling functions


  • Doesn’t support old iOS versions
  • Cannot call C++ code without wrapping the functionality

Facebook, Instagram, and Twitter are developed by using Swift.

2. Objective-C

Objective-C is one of the primary programming languages for writing software for OS X and iOS. Tom Love and Brad Cox developed objective-C in 1984. It is used to build applications like iPhone, iPad, Apple TV, and Apple Watch. In addition, it helps you build heavy apps.

Key features of objective-C

  • Objective-C automatically creates and manages the MetaClass during the run time.
  • It offers a small comment section that looks like a conversation to make it more understandable.
  • You can easily implement delegating methods to other objects and remote invocation using categories and message forwarding.
  • They are flexible and provides an easy solution to programming issues.


  • You can easily connect them with private APIs.
  • Compatible with C++ libraries.
  • It does not launch regular updates and stays steady.


  • It has complex memory management, so that it is difficult to understand.
  • You need C or Smalltalk to understand it.
  • It cannot support big libraries.

Pinterest, Snapchat, and Slack are developed by using Swift.

Hybrid iOS app development

1. C++

C++ is an object-oriented programming language that supports the implementation of low-level manipulation problems. It is very flexible so that iOS app developers can easily develop different operating systems, browsers, and iOS game development.

Nowadays, C++ has become essential due to two reasons.

  1. The ANSI- with the implementation of object-oriented programming, it became easy for C++ to tackle real-world problems.
  2. The Annotated C++ reference manual.

Key features of C++

  • Object-oriented programming
  • Case-sensitive
  • Compiler-based
  • Speed
  • Dynamic Memory Allocation
  • Standard C++ libraries


  • With the platform independence, users can run the same program on different operating systems.
  • C++ is object-oriented, which means it offers concepts like classes, inheritance, polymorphism, data abstraction, and encapsulation. It makes the program more reliable due to code reusability.
  • C++ has total control over memory management.
  • Scalability
  • Compatibility with C


  • Pointers are difficult to understand, therefore a single misuse can crash your program.
  • You may face some security issues because of the availability of friend functions and pointers.
  • No garbage collector to collect the unnecessary data.
  • C++ does not support built-in threads.  

YouTube, Amazon, and Spotify are developed by using C++.

2. JavaScript

JavaScript was created by Netscape in 1995 and was released in 1996 alongside initial support for CSS and extensions to HTML. It runs smoothly in different environments and outside of the browsers, allowing you to have complete control over the app development process.

Most of the applications work as a result of the interaction between the user and the server. However, this connection takes time and resources. JavaScript helps to dodge it by allowing the validation of forms without the input of the users. This process saves time and reduces network traffic, resulting in an interactive and user-friendly website.  

Key features of JavaScript-

  • It is a lightweight programming language that can easily handle browser data.
  • It is time-saving, as it quickly resolves errors by validating user input.
  • Reduces server load and network traffic.

  • The structure of JavaScript is practical and straightforward to implement; thus, it is easier for both developers and users.
  • Due to its flexibility to work with other programming languages, most iOS app developers prefer it over other languages.
  • You can quickly implement it on a webpage or inside the script of another programming language.


  • JavaScript can include other resources without authentication, increasing the risk of compromising the client data.
  • Each browser interprets JavaScript differently; therefore it requires initial checking before publishing.
  • It lacks a debugging facility.
  • A single code error can stop the entire code from running on the website.

Uber, Candy crush, and LinkedIn are developed by using JavaScript.
