ios programming languages

Today, as mobile applications become integral parts of our everyday routines, it’s essential to have more highly skilled developers using appropriate tools.  

In 2024, the iOS app development environment looks vast with multiple programming languages with their strengths and applicability in varied projects.  

The objective of this guide is to navigate this complex landscape to assist you in picking the right language for your next iOS app which will eventually be rolled out. 

But before we jumped in. 

Here’s a fun fact: 

Did you know that 1 out of every 7 people in the entire world has an iPhone? And get this… According to a report by Demand Sage, there may be an estimated 1.56 billion iPhones floating around the world at the end of 2024. That’s a lot of pocket-sized powerhouses.

What is a Programming Language? 

The way a programmer issues commands such that the computer comprehends is called a programming language. Instead of words and sentences, human beings use special codes which are just like lines in a play to tell the computer what it must do. 

Think of it this way: If you ask a friend to lend you a pen, then you are engaging in conversation by using language as well. Computer programming is a universal language, as well; it is a way of talking with computers! 

However, other computer “languages” like each with its own command syntax also exist, but they are usually used to run iOS devices such as the iPhone, iPad, and iPod Touch that are powered by Swift and Objective-C. 

Below are the needed specifications for the most popular languages for iOS app development. 

Key Considerations for Selecting a Language: 

Project Requirements: 

Consider the needs of your iOS app, from performance benchmarks to compatibility with present-day system architectures to inclusion with third-party APIs. 

Match that with the programming language perfect for the job, considering factors such as available resources and development speed. 

Team Expertise: 

What programming languages are your developers experienced with? or Familiar with?  

Use their skill sets as a guideline. Choosing a language familiar to the team will mean quicker development turnarounds with less of a learning curve. 

Community and Support: 

How big is the programming language community?  

How active are they when it comes to updating documentation and answering questions on community forums?  

What is available in terms of resources and documentation? 

In simple terms, having active communities means that you and your engineers will receive a lot of assistance.  

If you’re an iOS developer, using a language like Swift will let you leverage a vast library of code that has been written and maintained by others, and most of the tools support the Swift language.

2. Objective-C: Overview and Key Features 

An essential tool for iOS app developers has always been Objective-C. The early 1980s saw the birth of Objective-C, which gained popularity in the 1990s when Apple started using it to construct macOS and iOS.  

Objective-C still has its own, even if Swift has recently taken over as the main language for iOS development. Maintaining legacy codebases and interfacing with earlier frameworks continue to be major responsibilities of the language. 

features of objective C

Key Features of Objective-C: 

Object-oriented:  

  • Create code that revolves around “objects” that have qualities and actions, just like real-world objects.  
  • Make code blocks that may be reused in other areas of your application and that function on their own.  
  • Big projects are easier to manage when the code is well-organized and reusable.  

Variable Duration of Run:  

  • Dynamic: Decisions are made during runtime rather than compilation.  
  • Flexible: Adjusts to circumstances and decides when to resolve method calls.  
  • Strong: Allows late binding and dynamic types for flexible coding.  
  • Good for: Modifying behavior, responding to unforeseen circumstances, etc.  

C Compatibility:  

  • Superset of C: Easily incorporate pre-existing C code and libraries into your iOS applications.  
  • Low-level functionality: For more precise control, access low-level system resources.  
  • Large-scale resources: Use the extensive C library for more complex tasks.  
  • Third-party libraries: For maximum efficiency, incorporate pre-built C libraries.  

Advantages and Disadvantages of Using Objective-C Programming Language: 

Advantages of Objective-C Disadvantages of Objective-C 
C Compatibility:  
 Easy transition for C developers: Transitioning from C to Objective-C is simple for developers who are experienced with C.  C library reuse: Objective-C libraries can be used with pre-existing C libraries.  Gradual integration of C code: By utilizing object-oriented capabilities, Objective-C may be integrated with C code.  Access to core: Access to legacy frameworks and the Core Foundation is made possible by C compatibility.   
Syntax Complexity:   The syntax of Objective-C is less intuitive than that of more recent languages, such as Swift, due to its complexity.  The readability of method calls is hampered by square brackets.  Pointer arithmetic increases confusion and complexity.  Overall, it is more difficult to understand and operate than contemporary frameworks.   
Mature Ecosystem:   Rich resource library: For quicker project development, years of development have produced an enormous array of both commercial and open-source libraries and frameworks.  Support for developers: Resources accelerate development and time-to-market by meeting every conceivable demand, including code sharing and community forums.  Effective development: Offers the appropriate resources and a quick-paced setting for the creation of iOS apps.   Memory Management:   Manual: Memory Allocation and Deallocation are managed manually by developers.  Reference counting: Monitors object use and deallocate when not in use.  Automatic Reference Counting (ARC): Refers to counting easier, however, memory leaks still happen.  Caution: Developers must still be careful, avoiding leaks and maintaining cycles.   
Dynamic Features:   Runtime decisions and flexibility: They are made possible by dynamic runtime, which adjusts to changes.  Message forwarding: Facilitates late binding and dynamic object interactions.  Introspection: At runtime, code is capable of self-analysis, which opens new functionality.   Learning Curve:   Objective-C’s unique syntax and dynamic runtime could be difficult for a beginner to understand when compared to more modern languages like Swift.   Swift is typically suggested for beginner developers due to its simpler syntax and friendliness to beginners, especially those without prior experience with iOS.
