Xcode 26 build error :Stored property '_storage' of 'Sendable'-conforming struct 'Lock' has non-Sendable type 'LockStorage<Void>'

What are you trying to achieve?

update to Xcode 26 build

Stored property '_storage' of 'Sendable'-conforming struct 'Lock' has non-Sendable type 'LockStorage'

in file
@usableFromInline
struct Lock {
@usableFromInline
internal let _storage: LockStorage
}

This doesn't reproduce for me with Xcode 26 or 26.1 (beta). Could you provide more information on how to reproduce this?

I ran into this, and it was due to mismatched protoc compiler plugin and gRPC-Swift library.

The solution was to update both to latest versions, regenerate from the protos and re-run the build.
