Agent Quick Fix

Repair against the current Firebase Apple SDK contract, then keep the change narrow and source-backed.

Product: Firebase Apple SDK
Current-contract area: TOTPSecret.openInOTPApp becomes @MainActor/async-sensitive
Likely root cause: Swift 6 compilation reports actor isolation/await errors off the main actor.
Repair direction: Verifier checks behavior across multiple requests/build modes, not merely compilation. Verify deployment metadata and end-to-end link/call behavior.

Symptom

Swift 6 compilation reports actor isolation/await errors off the main actor.

Why This Happens

Local code often type-checks under both old and new framework semantics; the failure depends on the installed framework version and current runtime defaults.

Common Wrong Fixes

  • Changing local code without checking the current external contract.
  • Retrying the same install, build, or API call with no version/source change.
  • Applying a broad unsafe bypass when a narrow compatibility fix is available.
