AnnotationsĪnnotations are the easiest way to add metadata to the code. Swift utilizes ARC or Automatic Reference Counting for memory management, whereas Kotlin uses Garbage Collection. Kotlin and Swift implement a different approach to memory management. Kotlin does not have a guard statement.Kotlin does not have strut or passing data by value.All the classes in Kotlin are final by default.Delegated Classes and properties are missing in Swift.Enums in swift is considered more powerful than that of Kotlin.Let’s have a look at the key differences of both languages: Head To Head Comparison between Kotlin and Swift (Infographics)īelow are the top 5 differences between Kotlin vs Swift:īoth Kotlin vs swift are powerful languages to develop IOS and Android development. Easy error handling allows the programmers to handle unexpected errors at the run time in an efficient and user-friendly manner.Programmers do not need to write extra lines of code for memory management it utilizes automatic reference counting for memory management.Arrays and lists are checked of Out of Bound Index errors.It tends to initialize the variable at the start of the program before it is being called.Swift avoids using large classes that are error-prone and adopts modern programming patterns, such as Thus it is not just easier to write the code, but also the code’s maintenance is hassle-free. Swift libraries have a vast set of predefined methods that can be readily used to structure the logic. It is built on top of the modern programming approach that combines safety and design pattern, which allows the programmer to code efficiently and easily. Swift allows writing codes compatible with phones, desktops, servers, or any device that executes the code. Chris Lattner develops it with an aim to overcome issues and difficulties in Objective C. It is an object-oriented, functional, block-structured general-purpose language. It is the most preferred and most popular programming language for iOS applications, watchOS applications, tv application, and macOS applications.
