Developers can mix modules built in different language modes (such as Swift 5 and Swift 6) in their apps without any issues. Migrating an app to Swift 6 does not require immediate migration of dependencies to the same language mode. It is possible to continue using Swift 5 modules in an app even after transitioning to Swift 6 language mode, and vice versa. This flexibility allows developers to manage the migration process at their own pace, making it convenient and seamless.
This week we had the opportunity to talk to Holly Borla who manages the Swift Compiler Team at Apple. We chat about upcoming Swift 6 changes and why they're a big deal, but also why you shouldn’t worry too much. Of course, all three of us pick packages, too!
