![]() ![]() How is this book different than macOS by Tutorials? ![]() The complexities and joys of programming macOS. ![]() Instead, you’ll develop complete, fully-formed apps, while exploring many of You’re not going to create quick example programs thatĭemonstrate how to accomplish a single feature. Instead of just covering a list of features, macOS Apprentice does something much more important: It explains how all theīuilding blocks fit together and what is involved in building real apps. MacOS Apprentice doesn’t cover every single feature of macOS it focuses on the absolutely essential ones. You’ll explore several different ways to run Swift code, taking advantage of the fact that you’re developing natively It walks you through installing Xcode and then teaches you the basics of the Swift programming language. The first section assumes you have little to no knowledge of programming in Swift. Guides you in a fun and easy-going manner. Uses tons of illustrations and screenshots to make everything clear. Shows you how to write an app step-by-step. If you’re new to macOS and Swift, or to programming in general, learning how to write an app can seem Along the way, you’ll learn several ways to execute Swift code and you’ll build MacOS apps in Swift, using both SwiftUI - Apple’s newest user interface technology - and AppKit - the We will add the same 13.0, *) on top of them as well : // 13.0, *)įunc application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.MacOS Apprentice is a series of multi-chapter tutorials where you’ll learn about developing native Next, there are two new methods added in AppDelegate.swift, which only supports iOS 13 and above. To do this, we will add this line " 13.0, *)" right above the SceneDelegate class declaration like this : import 13.0, *)Ĭlass SceneDelegate: UIResponder, UIWindowSceneDelegate out some methods in AppDelegate.swift If you haven't already, change the deployment target to the lowest iOS version you want to support, select the project name then select your app target, choose General and change the version in Deployment out the SceneDelegate.swiftĪs the SceneDelegate class is only available on iOS 13 and above, we have to tell the compiler to only include the class for iOS 13 and above. If you are dropping support for iOS 12 and below, you are denying half of the iOS users to use your app! □ Update deployment target But keep in mind that half of the iOS devices in circulation are not using iOS 13 as of mid October 2019, according to Apple's report : You can save the hassle by setting deployment target to iOS 13 and above, and ditch support for iOS 12 and below □. We will try to resolve these errors step by step in this article. As iOS 12 and earlier don't have these feature, we will get these error messages when trying to compile. Notice that most of these errors are related to the UIScene class and the SceneDelegate.swift file, these are related to the multi-window feature introduced in iOS 13, which allows multiple windows of an app to be opened in iPad. If you create a new app in Xcode 11 and try to run it on an iOS 12 device or lower, you will get a bunch of errors : ![]()
