In Xcode 15 code completion we can view all the possible permutations of function parameters by pressing the right arrow key.

Xcode 15 automatically generates static properties on ColorResource and ImageResource types for colors and images that we store in asset catalog. This lets us access them in SwiftUI, UIKit or AppKit code without using string literals.

Starting from Xcode 14, iOS simulator can generate a device token, allowing us to test remote push notifications coming from a server without a real device or a need to use .apns payload files and simctl push command.

Make sure that all of the necessary strings are localizable in a SwiftUI app by previewing your UI in the accented pseudolanguage.

Generate xcloc files that can be sent to translators directly from SwiftUI code and import translations back to create Localizable.strings files.

Make use of Xcode shortcuts to correct code indentation quickly.

View and manage files created by your app on the simulator, browse the Documents folder or Core Data SQLite Database.

If you need to release an app built with an older version of Xcode, but want to test the app on the beta iOS simulators, you can follow the steps described in this article to transfer your build to the beta simulator.
