Swift vs. Objective-C: Choosing the Right Language for iOS Development

Rate this post

Swift and Objective-C are the two primary programming languages used to develop iOS apps. Swift is a newer language, introduced by Apple in 2014, while Objective-C has been around since the late 1980s.

Both languages have their own strengths and weaknesses, and the best choice for a particular project will depend on a number of factors, including the team’s experience, the project’s requirements, and the developer’s personal preference.

Swift vs Objective-C

Swift and Objective-C are both programming languages used for iOS, macOS, watchOS, and tvOS app development on Apple’s platforms. They have different histories, design philosophies, and features.


Swift is a modern, expressive language that is designed to be easy to learn and use. It has a number of features that make it a good choice for iOS development, including:

  • Safety: Swift is a type-safe language, which means that it can help to prevent errors caused by type mismatches.
  • Performance: Swift is a compiled language, which means that it can generate machine code that is very efficient.
  • Expressiveness: Swift has a concise and expressive syntax, which makes it easy to write readable and maintainable code.


Objective-C is a superset of the C programming language, with additional features that make it suitable for object-oriented programming. It is the language that was used to develop all iOS apps prior to the introduction of Swift.

Objective-C is a mature and well-established language, and it has a number of advantages, including:

  • Large community: Objective-C has a large and active community of developers. This means that there are plenty of resources available to help developers learn the language and solve problems.
  • Compatibility: Objective-C code is compatible with all older versions of iOS. This is important for developers who need to maintain legacy code or support older devices.

Difference between Swift and Objective-C

Age and HistoryIntroduced in 2014Developed in the 1980s
SyntaxConcise and expressiveC-based with Smalltalk-style messaging
SafetyStatically-typed (compile-time checks)Dynamically-typed (runtime checks)
Memory ManagementAutomatic Reference Counting (ARC)Manual memory management (retain/release)
InteroperabilityHighly interoperable with Objective-CInteroperable with C/C++
PerformanceGenerally slightly fasterOptimized over the years
Community and EcosystemGrowing and active communityMature ecosystem with many resources

Choosing the right language

When choosing between Swift and Objective-C for iOS development, there are a number of factors to consider:

  • Team experience: If the team has experience with Objective-C, it may be easier to continue using that language. However, Swift is a relatively easy language to learn, so it is possible for teams to switch to Swift even if they have no prior experience with the language.
  • Project requirements: If the project requires support for older versions of iOS, then Objective-C is the only choice. However, if the project can be targeted to newer versions of iOS, then either language can be used.
  • Developer preference: Ultimately, the best language to use is the one that the developer is most comfortable with. Both Swift and Objective-C are powerful languages that can be used to develop high-quality iOS apps.


Swift and Objective-C are both excellent languages for iOS development. The best choice for a particular project will depend on a number of factors, including the team’s experience, the project’s requirements, and the developer’s personal preference.
