Inspecting 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:

  1. Verify slice architecture: 
    lipo -info Pods/TargetFramework/TargetFramework.framework/TargetFramework
  2. In Xcode Build Settings, search for Excluded Architectures and ensure arm64 is NOT excluded for Any iOS/macOS SDK.
  3. Purge build cache: 
    rm -rf ~/Library/Developer/Xcode/DerivedData/* && xcodebuild clean

Following this procedure restores full stability with zero recurring log errors.
