I'm trying to figure out how long does the Swift compiler take to build my app every time and reduce time on type checks and functions where possible. I found many articles on the internet, explaining how to add these "Other Swift Flags" in the Build Settings of the Target to get Build Time warnings in Xcode.
-Xfrontend -warn-long-expression-type-checking=100
-Xfrontend -warn-long-function-bodies=100
One such article here, for context.
The problem is that Xcode shows warnings about files only in the main app. I have a number of local Swift packages in the project and I can't find a way to do the same checks on the code inside those packages.
I tried adding these Swift Flags to the Project and the Target in Xcode, but it is of no use. I can't find anywhere to specify such flags for Swift Packages.
