Cannot archive build on Xcode 13 beta 3

[d-date]

Describe the bug

When running archive build on Xcode 13 beta 3, the build fail since it depends on Combine.framework built by different compiler version.

Failed to build module 'Combine'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.5 (swiftlang-1300.0.24.14 clang-1300.0.25.10)', while this compiler is 'Apple Swift version 5.5 (swiftlang-1300.0.24.13 clang-1300.0.25.10)'). Please select a toolchain which matches the SDK.

Environment

• Xcode 13 beta 3
• Swift 5.5

Hi @d-date! I'm able to successfully build a project that depends on CombineSchedulers in beta 3. The error message you posted makes it sound like you have a custom toolchain selected in Xcode. Can you check the "Xcode > Toolchains" menu and verify that "Xcode 13.0" is selected?

The only other thing I can think of is maybe you have some stale build products getting in the way. "Product > Clean Build Folder" could help, or you could try fully deleting the Derived Data folder.

@stephencelis
Did you succeed in the Archive, right?
I'm able to build and run, but archive has failed.

As you say, I checked that Xcode 13 was selected as the toolchain. I also tried a clean build, but didn't change.

I am also seeing this error. Although to start I am suspecting beta 3 or maybe something about my workspace configuration more than combine-schedulers per se.

I don't think I have any alternative toolchains installed. (The toolchain items don't even appear in the Xcode menu or Preferences > Components.) Deleted derived data. M1 Mac, if it matters.

Seems to be the same issue:

😢 oof, good to know.

I'm going to covert this to a discussion since it's not really a CombineSchedulers issue and so that we can continue sharing information about it.
