Rewriting the above code example by making use of async-await explains best what structured concurrency does: do { // 1. Call the method let images = try await fetchImages() // 2. Fetch images method returns // 3. The strong reference to self is created at block execution time while using self in the block is evaluated at block declaration time, thus retaining the object. For best practice, however, you should create a strong reference of your object using the weak one. This won't create a retain cycle either as the strong pointer within the block will ...Web11. /**.
