Swift vs. Objective-C: A Look at iOS Programming Languages

One of the first things you need to decide when you are contemplating the perfect iOS app is the language that you will use. There are primarily two options for iOS app development: Objective-C or the next-generation Swift.

You must think about the features, differences, pros, and cons of both of the options that you have available to you as you try to determine what is ideal for iOS application development.

So, without further ado, let’s get right into the details of Swift vs. Objective-C.

1. Swift :

In 2014, Apple created Swift, an incredibly popular programming language with high performance. Later, Chris Lattner worked with Apple programmers on developing the software. Swift resembles Objective-C in its object-oriented features and syntax. It was used to develop NEXTSTEP in the 1980s, and then for Mac OS and iOS. Programming challenges are eliminated by this language. Such as.

  • The memory allocation prevents the allocation of large numbers exceeding the allotted space.
  • It is possible to automatically manage memory.
  • To construct obstacles, variables must first be initialized.
  • The language is customized for Apple hardware, unlike most other languages.

Pros of Swift :

  • The most popular programming language in 2018 was Swift, which ranked 14th.
  • Swift is 8.4x faster than Python and 2.6x faster than Objective C when it comes to performance.
  • Code consists of clean and consistent lines because it has an encouraging syntax.
  • Readability is improved and errors are prevented.

Cons of Swift :

  • One drawback to Swift was that apps targeting iOS7 or later could only be developed.
  • Swift may be the fastest language of the era, but it is still a young language with some kinks that need to be worked on.
  • The talent pool for this language is limited.
  • The Swift programming language lacks a great deal of support for earlier versions of iOS.

2. Objective C :

The language Objective C is an object-oriented programming language designed for general-purpose use. A company called Stepstone created it under the leadership of Brad Cox and Tom Love. The specification and semantics of Objective C make it an object-oriented language and allow for syntax and semantics that are similar to those of C. Objective C is also commonly referred to as Obj C. Developed for OS X and iOS, it has several built-in libraries. This game was developed by Brad Cox and Tom Love at their firm Stepstone in the 1980s. The Objective C programming language extends the capabilities of C programming. Objective C source code has extensions in the form of .m files.

Pros of Objective C :

  • Language modules were developed as preprocessors for existing C compilers.
  • There are more compatibility issues with Objective C when compared to C++.
  • A more stable programming language is Objective C.
  • Private APIs can be easily used in Objective C.

Cons of Objective C :

  • Operator overloading is not supported in Objective C like it is in C++.
  • Objective C came with no garbage collection, but it still used a little C runtime to manage the garbage collection, which increased the size of the application.
  • A header file is needed because it was based on the C compiler.
  • It is evident that Objective C as a language is a little complex, to be expected as it is a relatively old language.

Difference between Swift and Objective C :

Metrics Swift Objective-C
Performance and Speed Performance-sensitive coding and high performance. Performance and speed are reduced by runtime-code, except for functions in C.
Code Safety Recognizing and fixing bugs quickly. Bugs can be caused by Null Pointer Persistence.
Convenient Maintenance There is only one code file to maintain. A developer’s job is complicated when there are two separate code files.
Syntax Coding is reminiscent of English but simpler. Puts symbols and parentheses in place.
Code Length & Complexity Reduce the number of lines of code for the same operation with concise coding. An overly verbose and lengthy text.
Memory Management Implements ARC with support for all APIs. There is no support for ARC outside of the Cocoa API.
Libraries Support Dynamic libraries can be integrated. No dynamic libraries are supported, so static libraries are used


To return to my original question, which is better?

Objective-C? Swift programming language?

Ultimately, you will have to decide.

Currently, Objective-C is more popular than C. The language is more difficult to learn, but the vast majority of developers know how it works.

Swift is still a new technology, but it’s rapidly advancing. There are no known vulnerabilities, and learning Objective-C is easy. The downside though is that large projects won’t be the best choice.

There are times when one language may work better for you than another based on your experience, the familiarity of your team, or the scope and timeline of your project.

Be sure to weigh your tooling support, stability, runtime, and API requirements.

Nevertheless, if you have questions about which one to choose, we have a solution.
