Charlotte HallInspecting binary slices via lipo, updating dependency architecture flags, and cleaning derived data.
Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:
- Verify slice architecture:
lipo -info Pods/TargetFramework/TargetFramework.framework/TargetFramework - In Xcode Build Settings, search for Excluded Architectures and ensure
arm64is NOT excluded for Any iOS/macOS SDK. - Purge build cache:
rm -rf ~/Library/Developer/Xcode/DerivedData/* && xcodebuild clean
Following this procedure restores full stability with zero recurring log errors.
