I'm trying to adopt the Xcode new build system in our project, which contain a development pod. After performing a clean build, I modify one of the swift file in the pod (just adding a empty line), and perform a Incremental build. In the Xcode report navigator, I check the latest building progress, and found out something is weird:
- Xcode stuck at
Compile Swift source filesfor a few seconds without compiling any swift file
- Xcode compile the changed swift file, merge swiftmodule, and stuck for addition nearly 60 seconds
- Xcode continue the building process
Any idea why Xcode stuck for such a long time?
