IOS Application Development With Swift 3.0

Overview Of Swift Language

Development of the Swift language started in 2010 by the Apple Inc. programmers. Earlier Apple uses Objective–C platform for the iOS application development and later on iOS technology deployed new forefront programming language called Swift. Swift language is not just for iOS or OSX development since it is an open source and also appeared for the Linux computers.
Swift 3 update came with many major updates with improvements such as core library, standardization of code, portability and its options. When migrating your project to swift 3.0 from an older version of swift, you need to transfer through Xcode 8.0. Make use of the Swift standard library to work in the latest version seamlessly.

Swift include many important components such as a swift compiler, standard library, core libraries, debugger, package manager etc. Swift language has no iOS-based libraries and that’s the good sign for the app developer.

Coding Experience

It is much easier to write a program for Mac OS X and iOS devices. Swift is developed for an easier programming language for reading and coding. Developers got rid of writing long and complicated codes for any application development. In Swift programming language, the syntax does not require semi-colons at the end of each line. Swift language requires fewer symbols to code and it’s more efficient than Objective-C.

Why Focus On Shift 3?

For developing any deliverable high-quality iOS based application, an organization focused on the most dynamic APIs, SDKs, and user-friendly programming platform. If you have an aggressive timeline to complete you’re projecting, then you should have to lean towards the Swift. Also being an open source language, you can also get help from a large community of developers available online.

Extra Features

Swift update 3.0 came up with some more interesting features.
Apple mainly focuses on creating a stable binary interface (ABI).
Swift uses complete generics (an algorithm that is incorporated when it is needed) throughout its library.
Swift 3.0 provides new API guidelines for the developers who are building API.

How Swift Differs From Objective-C?

Swift is gradually beating objective-C, becoming more popular for the iOS application development. Objective-C will still be in existence and Apple is also updating its own Frameworks to be written in Swift. Apple will not include the Swift realtime on iOS or OS X.
Header Section
Objective C was purely based on C but added OOP paradigms to the languages through the object messaging. Because of this reason, Objective-C made use of the header file that will show its function and definitions publicly.
Swift overcomes with new cleaner code practice, which allows developers to write a .swift single that contains all information such as header information, properties, and all classes dumped into a single file.

REPL (Read-Eval-Print-Loop)
Swift and Objective-C both are compiled languages, and Swift having a feature of REPL for testing that the only guide interpreted languages.
REPL is a simple interactive code editor in which you can type Swift code and lets you execute it immediately after. It reads the code and afterward, it evaluates the code, interpreting line by line an then it feeds to Swift compiler.
