Xcode 💻 15 has a new linker. All operations are performed in parallel. They write about a 5x increase. Linking takes place after compilation, so the build time will not increase by 5x.

Also presented mergeable libraries are dynamic libraries with metadata, with them static linker can do linking.

About 👶 SwiftUI: Apple leaves only State and Environment (1) The new Observable macro removes the Published property. The code is much cleaner (2)

Macros simplify the code, but everything remains accessible - nothing is depricated.
