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.

Diagnostic Hardware Specs: Mac Studio M2 Max (32GB) | OS Version: macOS Sonoma 14.7 + Xcode 16.0 | Archive Source: Apple Support Community #256106389

I am running into a persistent issue on my Mac Studio M2 Max (32GB) running macOS Sonoma 14.7 + Xcode 16.0.
Whenever the machine encounters Missing universal arm64 binary slice in legacy CocoaPods or precompiled dylib frameworks, the following diagnostic log appears in Console:

ld: symbol(s) not found for architecture arm64; clang: error: linker command failed with exit code 1 (use -v to see invocation)

I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?
