Compilation Error with Xcode 26

[tdufourheadcheck]

Describe the bug?

Hi,

Since updating to Xcode 26, I have some compilation errors coming from the OktaBrowserSignin pod library.

They are all the same errors. Here is one example. File AuthorizationCodeFlow.swift, line 222.

Compilation error: "Call to actor-isolated instance method 'finished()' in a synchronous nonisolated context".

I can fix the issue by modifying

finally: {
  finished()
}

to

finally: {
  Task { @MainActor in
    await finished()
  }
}

But I'd prefer to not manually modify external library code if at all possible. I'm also not an expert at all in Swift 6 concurrency code.

Is there another way to fix the issue? A project setting perhaps?

What is expected to happen?

No compilation error.

What is the actual behavior?

There are multiple compilation errors like the one described above.

Reproduction Steps?

-Download latest Xcode (26.2 at the moment)
-Install the OktaBrowserSignin pod library using cocoapods

Additional Information?

My project is still on Swift 5, not Swift 6.

SDK Version(s)
