Diagnostic Hardware Specs: Mac mini M4 Pro (48GB) | OS Version: macOS Sonoma 14.7 + Xcode 16.0 | Archive Source: Apple Support Community #256226343

I am running into a persistent issue on my Mac mini M4 Pro (48GB) 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?

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.
