The first step in migrating to Xcode 16 involves ensuring that your app builds with the latest Xcode version. This is confirmed in the session "Migrate your app to Swift 6" where it is mentioned that your app should build with the new compiler, even before enabling the Swift 6 language mode. This step ensures that your app is compatible with the new Xcode environment.

Once you have confirmed that your app builds correctly, the next step is to enable complete concurrency checking. This is a per-module setting that leaves your project in Swift 5 mode but enables warnings for all the code that would fail with Swift 6's enforced data isolation. This step helps you identify and resolve potential issues before fully migrating to Swift 6.

For more detailed guidance, you can refer to the session "Migrate your app to Swift 6 (07:17)".
