Backed up by one of the most influential tech companies in the world, Swift is set to become the dominant language for iOS development and beyond. Here’s what you need to know about Swift.Ĭreated by Apple in 2014. Swift is a compiled programming language for iOS, macOS, watchOS, tvOS, and Linux applications. If you decide to go for native development instead of cross-platform solutions, you still have to decide which language to use: the good old Objective-C or brand-new Swift. What you have to choose is the right tech stack for your product. Having in mind so many people’s unfading loyalty to Apple devices, iOS app development is more relevant than ever. However, if we look at the US map, iOS is leading the race with 56.7 percent, and its rival has 43 percent.

What is Swift and why should you use it?.

It’s much better to terminate immediately and give us a clear explanation of what went wrong so we can correct the problem, and that’s exactly what fatalError() does. I realize that sounds bad, but what it lets us do is important: for problems like this one, such as if we forget to include a file in our project, there is no point trying to make our app struggle on in a broken state. Not “might die” or “maybe die”: it will always just terminate straight away. When we call fatalError() it will – unconditionally and always – cause our app to crash.

Regardless of what caused it, this is a situation that never ought to happen, and Swift gives us a function called fatalError() that lets us respond to unresolvable problems really clearly. Pick one random word from there to be assigned to rootWord, or use a sensible default if the array is empty.Įach of those four tasks corresponds to one line of code, but there’s a twist: what if we can’t locate start.txt in our app bundle, or if we can locate it but we can’t load it? In that case we have a serious problem, because our app is really broken – either we forgot to include the file somehow (in which case our game won’t work), or we included it but for some reason iOS refused to let us read it (in which case our game won’t work, and our app is broken).Split that string into array of strings, with each element being one word.

What we need to do now is write a new method called startGame() that will: We already defined a property called rootWord, which will contain the word we want the player to spell from. This was included in the files for this project that you should have downloaded from GitHub, so please drag start.txt into your project now. In our game, we’re going to include a file called “start.txt”, which includes over 10,000 eight-letter words that will be randomly selected for the player to work with. This “.app” extension is automatically recognized by iOS and Apple’s other platforms, which is why if you double-click something like Notes.app on macOS it knows to launch the program inside the bundle. When Xcode builds an iOS project, it puts your compiled program, your asset catalog, and any other assets into a single directory called a bundle, then gives that bundle the name YourAppName.app.
