Minimum platform level
Firebase Apple SDK 12.0.0 minimum iOS 15 release notes
Pod/SPM resolution or Xcode build fails for an app declaring iOS 13/14 support.
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: Firebase 12 raises iOS minimum to 15
Likely root cause: Pod/SPM resolution or Xcode build fails for an app declaring iOS 13/14 support.
Repair direction: Verifier checks an explicit product decision: raise the app floor with metadata/tests, or pin a still-supported SDK line. Verify deployment metadata and end-to-end link/call behavior.Symptom
Pod/SPM resolution or Xcode build fails for an app declaring iOS 13/14 support.
Why This Happens
The source can compile on the developer's newer device while the SDK's newly raised deployment/minSdk target fails older build or runtime matrices.
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.
