For our Swift projects we only use the Swift Package Manager (SPM) and when we are running a job inside our GitLab pipeline, it can take forever to resolve those dependencies.
We use fastlane gym action, which basically does xcodebuild as you can see here:
Resolving Swift Package Manager dependencies...
$ xcodebuild -resolvePackageDependencies -scheme X -project X.xcodeproj -configuration Release -scmProvider system
It took 10 minutes for 20 packages, I mean it doesn't sound like much, but feels like it and when you have to do this everytime we run a pipeline, this slows us down a lot.
So maybe someone can explain to me, why it needs to resolve package dependencies and how we could increase the speed doing it on our CI.
