This is important for me as well. I sent a feedback from the app about it. I think that that's the channel to let the team know about our concerns.

If in the latest update this issue is still present, try turning off iCloud sync for Swift Playground, and turn it back on again. This usually fixes the app, and let you open your documents. Hope this helps.

@julianoctvaz I do this in my projects Package.swift file: .executableTarget( name: "AppModule", path: ".", resources: [ .process("Resources") ] ) Then, having Assets.xcassets folder at the same level of Package.swift, it will have all the assets available in the project. Hope this helps!
