How are you testing async isolation changes alongside @abi?
STARTER DISCUSSION — iSwift editorial prompt, not a member bug report.
A September report describes a compilation failure when @abi is used with async function parameters whose nonisolated(nonsending) annotations differ.
DISCUSS
Can you reproduce the report on your exact toolchain? What is the smallest signature change that changes the diagnostic? Share your compiler version, flags and a reduced example.
Include: Swift/Xcode version, operating system, build flags, expected result and actual result. Do not include passwords or private project code.

The upstream report was open when checked on October 4, 2026. Status can change; read the issue before relying on any workaround. iSwift has not independently reproduced this bug.
