In this article, we’ll answer that question and also tell you what you can do to reduce the amount of space it takes up. Or maybe you’ve tried to download it and got an error telling you that you don’t have enough space to install it and can’t work out why Xcode is so big.

If you’ve installed Xcode on your Mac and only just discovered how much space it’s taking up on your boot drive, you may be wondering why it’s so large.

But to help you do it all by yourself, we’ve gathered our best ideas and solutions below.įeatures described in this article refer to the MacPaw site version of CleanMyMac X. We will add the same 13.0, *) on top of them as well : // 13.0, *)įunc application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.So here’s a tip for you: Download CleanMyMac to quickly solve some of the issues mentioned in this article. 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 :
