swift-async-algorithms 1.0.1 can no longer be built in Swift Playgrounds on iPadOS #316
Description
#311 has broken apps depending on swift-async-algorithms on Swift Playgrounds on iPadOS.
- iPadOS 18 Developer Beta 1
- Swift Playgrounds 4.5.1
The reproducible example is here. Or, you can reproduce the issue by the following steps.
- Create a new app on Swift Playgrounds (iPadOS)
- Add a swift package
- Input https://github.com/apple/swift-async-algorithms to the "Package URL" field
- Press the return key
Then, the following error will be shown.
