Write safe Swift code avoiding memory leaks, optional traps, and concurrency bugs.
Write safe Swift code avoiding memory leaks, optional traps, and concurrency bugs.
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Force unwrap ! crashes on nil β use guard let or if let instead Closures capturing self strongly create retain cycles β use [weak self] in escaping closures Delegates must be weak β strong delegate = object never deallocates try! crashes on any error β never use in production paths removeFirst() crashes on empty β use popFirst() for safety
async let starts immediately β not when you await Actor reentrancy at every await β state may change between suspension points @MainActor doesn't guarantee immediate main thread β it's queued Sendable conformance violations crash at runtime β compiler warnings are errors
Protocol extensions don't override β static dispatch ignores subclass implementation Mutating struct in collection requires reassignment β array[0].mutate() doesn't work String.Index from one string invalid on another β even if contents match
@StateObject owns, @ObservedObject borrows β recreating view loses ObservedObject state @EnvironmentObject crashes if not injected β no compile-time check View identity change resets all @State β changing ID loses state
print() builds strings even in release β remove or use os_log Generic code bloat β specialized for each type, increases binary size
Agent frameworks, memory systems, reasoning layers, and model-native orchestration.
Largest current source with strong distribution and engagement signals.
