What is the Difference Between Objective C and Swift?
🆚 Go to Comparative Table 🆚Objective-C and Swift are two programming languages used for iOS app development. They have some key differences:
- Syntax: Objective-C has a syntax filled with square brackets and semicolons, making it difficult for developers to focus on the core of the code. Swift, on the other hand, offers a cleaner, more concise syntax that resembles plain English, making it easier to understand and learn.
- File Structure: In Objective-C, the interface is separated from the implementation, with the interface living in the header file (Filename.h) and the implementation in the "*.m" file. In Swift, the interface and implementation are both in the same file.
- Typing: Objective-C uses a mix of static and dynamic typing, while Swift has type inference, allowing the compiler to automatically infer the type of a variable based on its value. This means that you don't have to explicitly declare the type of a variable, reducing the likelihood of type mismatches.
- Memory Management: Swift has better memory management features than Objective-C, which can help improve performance. It uses lazy initialization, reducing memory usage since unused variables do not initialize.
- Performance: Swift is generally faster than Objective-C, with performance improvements ranging from 2.6x faster than Objective-C and 8.4x faster than Python.
- Popularity: Swift has gained popularity among developers since its release in 2014, and it is now the primary language used for iOS app development. Objective-C, on the other hand, is considered outdated by many developers.
In summary, Swift is a more modern, concise, and efficient language compared to Objective-C, making it the preferred choice for iOS app development in most cases.

Comparative Table: Objective C vs Swift
Here is a table comparing the differences between Objective-C and Swift:
Feature | Objective-C | Swift |
---|---|---|
Speed of Performance | Slower | Faster (2.6x times more rapid) |
String Manipulation | More complex (e.g., mutable vs. immutable strings) | Simpler (var/let for string mutability, easy concatenation) |
Control Flow | Older syntax and less readable | Simplified syntax, easier to read |
Type Inference | Requires explicit type declarations | Infers types automatically, reduces code clutter |
Tuples | Not supported | Supported |
Optionals | Not supported | Supported, simplifies error handling |
Functional Programming Features | Limited (blocks used instead) | Higher-order functions, functions as values, nested functions, closures, anonymous functions |
Enums | Limited functionality | Supports lines, characters, integers, and fractional numbers, more readable and less lengthy code |
Switch Statements | Complex and less readable | Supports more features, easier to implement and understand |
Learning Curve | Steeper curve due to older syntax and limited modern features | Easier to learn due to simpler syntax and modern features |
In summary, Swift offers several advantages over Objective-C, including faster performance, simpler string manipulation, improved control flow, and support for modern programming features. Swift's syntax is more unified and easier to learn, making it a more attractive choice for new developers.
