async.swift

func someAsyncFunc(result: @escaping (Result<Void, Error>) -> Void) {
    DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(3)) {
        result(.success(()))
    }
}

let runner = SwiftScriptRunner()

runner.lock()
someAsyncFunc { result in
    // Handle result
    runner.unlock()
}
