Calling Native Code From Ruby
summary
CocoaPods’ xcodeproj removes its painful C extension by using Fiddle (MRI since 1.9) to call CoreFoundation for plist read/write and private Xcode APIs, loading symbols with dlopen/dlsym and caching function objects to avoid repeated setup. A simple name check triggers manual create/auto‑release handling and Objective‑C calls go through objc_msgSend. The result: no user compile failures (projects report >200 compile issues for C extensions), working wrappers but with a clear performance caveat.
