This seems to be an issue with the swift-package-manager dependency and Xcode12b4.

Compiling with 11.6 works on Big Sur:

env DEVELOPER_DIR="/Applications/Xcode_11.6.app" xcrun swift build

but

env DEVELOPER_DIR="/Applications/Xcode_12_beta_4.app" xcrun swift build

raises the above error.

I'll see if I can get both to work if I bump swift-package-manager to something newer.

I’ve tagged this as 0.18.0-b1 for now to see if the builds across versions hold up
