You can use the Swift compiler flags -warn-long-function-bodies and -warn-long-expression-type-checking to emit warnings for functions or expressions that take longer than a set time to type check. Surfacing these within your projects can help improve and manage type checking times which contribute to overall build times.

If you’re writing Swift concurrency code, add these compiler flags:
-Xfrontend -warn-concurrency -Xfrontend -enable-actor-data-race-checks(in Xcode: Other Swift Flags)
Warnings in Swift 5.5 identify unsafe constructs, will become errors in Swift 6.
