The display will expand to show the various permissions you can now request for your app. Select EggTimer in the Targets list (there will only be one target listed), then click Signing & Capabilities in the tabs across the top. To view or modify sandboxing for the Egg Timer app, select the project in the Project Navigator - this is the top entry with the blue icon. Starting with Xcode 12, this is enabled by default. As a general rule, you should keep your apps sandboxed, as this gives your apps less potential to cause problems. For macOS apps, this is optional however, if you want to distribute your apps through the Mac App Store, they must be sandboxed. For iOS apps, this is the only way to operate.
If you are an iOS developer, you will already be familiar with this concept – if not, read on.Ī sandboxed app has its own space to work in with separate file storage areas, no access to the files created by other apps and limited access and permissions. Open the Preferences window to check it as well. Open this project or your own project from Part 2 and run it to confirm that the UI is all in place. If you haven’t completed Part 2 or want to start with a clean slate, you can download the project files with the app UI laid out as it was at the end of Part 2. In this part, you are going to add the Swift code that will make your app come to life! Getting Started In Part 2, you created the user interface for a more complex app, but it doesn’t work yet as you have not coded anything.
