At its WWDC developer event these days, Apple stunned all of the developers within the audience by launching a new programing language referred to as Swift. This new language appears to be poised to replace Objective-C because the main programing language on Apple’s platforms.
Swift can use constant LLVM compiler & runtime as Apple’s Objective-C implementation, therefore Swift and Objective-C code will live side-by-side within the same application. The language provides access to any or all of the Cocoa and Cocoa bit options developers ar presently used to from Objective-C.
It should have same feel like Objective-C which has been used earlier. Apple says, it is supposed to “unify the procedural and object-oriented parts of the language.” It will diverge from Objective-C in additional than simply the syntax, though; it additionally options variable sorts like tuples and elective sorts. It additionally includes operators that aren’t found in Objective-C, which permit you to perform operations on floating-point numbers, as an example.
Few highlights of the language as per Apple:
- Closures (similar to blocks in C and Objective-C) unified with functions, pointers
- Tuples and multiple return values
- Generics
- Quick and curt iteration over a variety or collection
- Structs that support strategies, extensions, protocols.
- Purposeful programming patterns, e.g.: map and filter
In addition, Apple notes however the language was designed for safety, with variables that have to be compelled to be initialized before use, arrays and integers that ar checked for overflow and automatic memory management.
Swift support, of course, are going to be deeply integrated into Apple’s updated Xcode IDE. it'll associate interactive “Playground” that enables you to edit your code and watch however your changes influence your app in period. Xcode’s debugging console currently additionally supports Swift syntax natively.
According to Apple, Swift can give variety of serious speed benefits to developers. A Complex object type, for instance, will run 3.9x quicker than associate degree implementation of constant formula in Python. That’s additionally quicker than Objective-C, which is 2.8x faster than the Python version.
We will clearly got to take a better investigate this new programing language and the way it relates to alternative languages. Apple is creating the documentation on the market nowadays, each as Associate in Nursing iBook and on its developer web site.
Objective-C was continually a tough language to choose up for brand new developers. we'll even have to check if Swift makes obtaining started with app development on Apple’s platforms easier, however from a primary investigate the documentation, it undoubtedly feels a lot of accessible than Objective-C.
