Is Swift a Game Changer for Mobile App Development
The biggest announcement at Apple’s recently concluded Worldwide Developers Conference (WWDC) was something only developers will immediately understand and users only eventually benefit from a new programming language called Swift.
With Swift in the market, the main difference is that now it supports generics. Apple has taken a huge step in developing a new language. With generics, Apple embeds more security for apps. Swift runs along with Objective-C. As a developer, there is no need to replace the whole code with Swift. In the future, it may be possible that Apple replaces objective C completely with Swift.
Features of Swift
- Multiple return type
Modern features of Swift
Swift introduces “Playground”, which allows Mobile app developers to see their result at run time. This Playground has 3 screens Editor, Observer, Assistant Editor. With playground feature, developer can write the code separately and test it out without hampering other existing code. Developer can see the result of playground code without running whole application, thus saving time for development.
Until now it was mandatory to explicitly mention data type for the variable. With type inference add-on main features of the Swift language are that it is not mandatory to write data type for each variable. It explicitly catches data type of variable using an initial value that the developer has assigned.
Unicode character consists of almost all the characters in each and every native language.
Earlier variables and constants name used had its own naming conversions like a variable should not content special characters or it should not start with an integer value. But now in Swift programming language, even developer can use Unicode character for variables and constants naming convention
One of the main features of Swift language is its type-safe language. It prevents passing different data type value to different data type variable. It catches exception at compile time itself if it finds any conflict in data type. Thus reducing run time overhead ensuring of this application runs faster. It also reduces run time application crashing.
Benefits of Swift over Objective-C
- It supports generics.
- No need to place semi-colon (;) at the end of line.
- Easy to check assigned values.
- Easy to check flaw in incrementing loop.
- Editor and Compiler (compile-time/run time) works simultaneously.
Looking at all the new advantages found in Swift it is safe to say that Swift will bring significant change in the developer’s community. The only problem now seems that very little is known about the language itself. We will have to wait for some time to find how changes are going to shape the iOS app world.
