error: module compiled with Swift 6.3 cannot be imported by the Swift 6.3.1 compiler

[VeneziaTech]

New issue for me on skip checkup --native
Xcode version 26.4.1
Apple Swift version 6.3.1 (swift-6.3.1-RELEASE)

Tried previous flow used in the past for same error on "Swift 6.2 cannot be imported by the Swift 6.2.1 compiler" but no result this time

:0: error: module compiled with Swift 6.3 cannot be imported by the Swift 6.3.1 compiler: /Users/paolorizzo/Library/org.swift.swiftpm/swift-sdks/swift-6.3-RELEASE_android.artifactbundle/swift-android/swift-resources/usr/lib/swift-aarch64/android/Swift.swiftmodule/aarch64-unknown-linux-android.swiftmodule

Any suggestions?
Thanks!!

Can you try running skip android sdk install --version 6.3.1 and then make sure it is working with skip checkup --native?

The problem may be because the underlying host toolchain is installed with swiftly, which treats "6.3" (the default toolchain version) as "6.3.WHATEVER_THE_LATEST_PATCH_IS`, but the Android SDK installation always treats "6.3" as "6.3.0".

Thanks for your answer!

Tried the procedure, same error

This might be a conflict with the latest Xcode update (26.5). Can you try updating the Swift toolchain once more with skip android sdk install --version 6.3.2 (which was just released today)?

If that doesn't help, can you show the output of the commands swift sdk list and swiftly list?

Good job!
Thanks!! Now it works!!
