#311 has broken apps depending on swift-async-algorithms on Swift Playgrounds on iPadOS.

  • iPadOS 18 Developer Beta 1
  • Swift Playgrounds 4.5.1

IMG_0442

The reproducible example is here. Or, you can reproduce the issue by the following steps.

  1. Create a new app on Swift Playgrounds (iPadOS)
  2. Add a swift package
  3. Input https://github.com/apple/swift-async-algorithms to the "Package URL" field
  4. Press the return key

Then, the following error will be shown.

error message 
Could not resolve package graph. Cannot continue.

It seems that Context is not safe on Swift Playgrounds. If Context.environment is used in Package.swift, Swift Playgrounds's SwiftPM will crash.

I also sent a feedback to Swift Playgrounds. FB13946579

Enclosing Context.environment with something like #if !os(iOS) would solve the problem. However, it may become a debt when the new Swift runtime other than Swift Playgrounds appears in the future on iOS or iPadOS.

Thanks for reporting this. This isn't an async-algorithms problem but rather a Swift Playgrounds/Swift PM problem. I am going to close this issue since this is now being tracked in the feedback you filed.
