![]() ![]() Swift is a safer and more secure language for building an app as per the present market trends. As the Swift code is written using data visualizations, this makes the app development process easier and approachable. With its Playgrounds feature, it let the programmers write a chunk of code or algorithm while gathering feedback along the development phase. This impressive figures cut the efforts of the developers without affecting the performance of the app at the customer end. This cut down the code length to nearly half, making it more readable.įor example, when Lyft app was rewritten in Swift language from scratch, the app code decreased from 75,000 to 25,000 lines. Furthermore, the Swift class is not divided into parts, the interface and the implementation. It empowers iOS developers to remove nested method calls, skip a semicolon at the end of a line, avoid putting at the beginning of a keyword, concatenate string using “+” sign, and so on. Unlike Objective-C, Swift is not tied to C foundations. Besides, its working is based on one of C++ fastest algorithm calculation arithmetics which in turn proves it to have a competitive edge over its predecessor.Īccording to what Apple claims and I have experienced, Swift search algorithm is 2.6 times faster than Objective-C. Swift for iOS development is a static-typed language which works with LLVM compiler and can reuse the existing code, eradicate unused resources, manage inline functions, and so on. Swift is an open-source language and the swift code can be portable on many more platforms than Objective-C was ever. Personally, I have seen the evolution of Swift since its first version was unveiled and I can say that between swift vs C, Swift supersedes Objective-C based on factors, like Open-Source In fact, Within the fight of swift or Objective-C for iOS, Various iOS apps like LinkedIn, Yahoo Weather, Hipmunk, and Lyft have already been upgraded from Objective-C to Swift, while many are planning to convert an Objective-C app to Swift. With this rise in popularity and exciting features, a lot of iOS application developers who were previously working with Obj-C has switched to Swift programming language. But the war of swift vs objective-C never mellows down. The programming language has managed to make its place in the chore of Top 10 Programming languages , sharing the position with its predecessor, Objective-C. However, they won’t mess up your project if you keep them around.Since its release back in 2014, Apple’s programming language Swift has undergone phenomenal growth. m files now, or keep them around for comparison. You can delete the corresponding Objective-C. Next, let’s create new Swift files for PeopleListViewController and PeopleDetailsViewController. We can now delete the main.m file (maybe in the Supporting Files group in Xcode), as this declaration replaces the need to have that main method. This represents the start of the program - the main() function. We need to add this file, right above the class declaration: The example above indicates that our AppDelegate class is a subclass of the UIResponder, denoted with the colon. You no longer need to explicitly import your class files either.Ĭlasses are declared with the class keyword, and all properties and methods will go inside the braces. The import statement is used to bring in frameworks, but you don’t need to use quotes or angled brackets anymore. We’re starting to see the new syntax that Swift brings. ![]() Once created, the file will have the following code (the exact code may change if you’re using a different version of Xcode): Call it AppDelegate, make it a subclass of UIResponder and change the language to Swift. Create a new file in Xcode (File > New > File…) and select a Cocoa Touch Class. We’ll start by transitioning the AppDelegate files. For our simple project, we’re going to migrate all three classes - the app delegate, main view controller, and detail view controller - at the same time. You can migrate your code one class at a time. Converting the projectĪpple makes it pretty easy to transition a project to Swift. Download the Objective-C version for the project here to get started. Swift is supported in Xcode 6, which currently (as if July 2014) is a beta available to registered iOS developers. We’ll start with the process of converting the Xcode project, and continue with rewriting our code in Swift. In this post, we’ll be converting our Objective-C app that works with web data to Swift. However, porting apps from Objective-C to this new language might take some getting used to. Apple’s new language, Swift, is supposed to make writing native iOS apps a lot faster and more fun. ![]()
