The Swift Package Manager relies on folder names very much. I found it impossible to create Package with folders layout not blessed by Swift Package Manager. This is issue for current project where Xcode has it's own layout of directories - incompatible with the approach of Swift Package Manager.
I tried create Package and failed. This is what I have build: https://github.com/krzyzanowskim/CryptoSwift/tree/develop/SwiftPackageManager it builds but I can't use it anywhere because it complain about folders.
and yes, I hate it
