💡 What: Refactored
removeContentsto usewithThrowingTaskGroupwith a sliding window approach (maxConcurrency = 8) and made it anonisolated async throwsmethod with an injectedFileManager.🎯 Why: Previous implementation deleted directory contents sequentially on the actor's executor, causing slow, serialized disk I/O when cleaning caches with thousands of files. The
TaskGroupsecurely parallelizes file deletion and retains original fail-fast semantics without legacy GCD or custom locks.📊 Impact: Substantially speeds up cache deletion by parallelizing
FileManager.removeItemcalls safely within Swift's structured concurrency model.🔬 Measurement: Observe faster cleanup times for large cache directories (e.g., Xcode DerivedData) in the application.
