2) Objective-C

Objective-C is a programming language that was developed as an extension of the C language to support object-oriented programming. It was created in 1984 by Tom Love and Brad Cox. It is a mature programming language that is simple to update. But that’s not all. It is more stable than Swift and has a high level of compatibility with C and C++ libraries. In fact, Apple first chose the Objective-C programming language for iOS app development. It was communicated by Apple co-founder Steve Jobs when he founded NeXT PCs in the 1980s.

Objective-C for iOS development — pros and cons

Objective-C is a type of dynamic programming language. It is mature and stable. This language is easily compatible with C++ libraries, and many legacy programmes support the nest coding style. Objective-C, on the other hand, is difficult to learn and is not available as open-source. Because it is an old programming language, security is a concern. Furthermore, the lack of strict typing leads to untraceable bugs. Because dynamic libraries are larger in size, they are not supported by Objective-C.

When to use Objective-C for iOS app development?

So, when is Objective-C actually a better choice? Objective C was the primary language for Apple iOS Programming language mobile apps at the time of Swift’s release in 2014. This programming language allows messages to be passed between objects, which is extremely useful for Apple’s iOS operating systems. As a result, using Objective C to develop iOS mobile apps will continue to pay dividends.

3) C++

C++ is an object-oriented programming language that is both powerful and flexible. It is one of the best languages for app development and one of the most difficult to learn. C++, or “C with Classes,” is a high-level, general-purpose programming language developed by Bjarne Stroustrup as an extension of the C programming language.

C++ language for iOS app development — pros and cons

C++ is a general-purpose programming language that is both fast and powerful. You have complete control over the app development process if you use C++. This language allows complete memory management control. C++ includes ready-to-use libraries and compilers. C++, as a powerful programming language, offers numerous advantages to both developers and end-users. However, there are some disadvantages. This programme is not ideal for web development because it is relatively difficult to learn, particularly for beginners. It has a complex syntax and small standard libraries. Furthermore, C++ is poorly designed and vulnerable to security flaws. Because it is so old and widely used, this programming language has two more drawbacks: a lack of a background garbage collector and a lack of GUI adaptability for different platforms.
