Can I use this for SwiftUI performance?

While the UI examples focus on UIKit, the core memory management and profiling concepts (ARC, Instruments, and concurrency) apply equally to SwiftUI.

How does this skill help with memory leaks?

It provides patterns for identifying retain cycles in closures and delegates, plus boilerplate code for verifying deallocation using deinit logging.

Does it include Instruments commands?

Yes, it includes specific CLI commands for launching xcrun xctrace with templates like Time Profiler, Allocations, and Leaks.

How does it improve list scrolling?

It offers specific patterns for cell reuse, prefetching, and GPU-accelerated layer properties to ensure smooth 60fps scrolling.
