Allow implicit self for weak self captures, after self is unwrapped. Concise magic file names. Opening existential arguments to optional parameters. Collection downcasts in cast patterns are now supported. Then, in setupClosure, closure keeps an additional strong reference of self to use its obj property. In this way, we are creating a strong reference cycle, since closure and self are keeping a strong reference of each other. We can break this strong reference cycle using self in the capture list with either a weak or an unowned reference: WeakIf the closure holds a strong reference, it prevents the ARC to release the object as long as the closure is still accessible. The weak and unowned self allow to resolve this strong ownership. But this means that the object referenced by the closure's weak self could be deinitailized while the closure could still be called.weak self captures in non-escaping closures now have the same behavior as captures in escaping closures (as described in SE-0365). Code relying on the previous behavior will need to be updated to either unwrap self (e.g. by adding a guard let self else return statement), or to use a different capture method (e.g. using [self] or [unowned self ... Jul 9, 2019 · But when the closure is called only once (like uploading an image) there is no need for a weak link in closures (in most but not all cases). In retrospective use closures as much as possible but avoid or use caution as soon as a closure is used as a property (which is ironically the example I gave). But you would rather do just this: Changes in Swift 5.8. Lift all limitations on variables in result builders. Function back deployment.

The idea behind this article is to give you all the tools so that you can start adopting async/await in your projects, baby steps at a time.Swift needs to ensure runtime safety, and will keep any objects it might need in the future alive, in this case by making a strong reference to self (since self is the only variable used inside the closure). In this scenario there is no reference cycle. This is because instanceA is not retained, so A => B, but B !=> A.Secondly, the completion closure will be called immediately as the "VC gets trashed during animation", and the finished argument will be false. So neither closures need [weak self].

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 common case when [weak self] makes most sense is when the closure is just updating the UI. If the UI is no longer visible, then it's generally fine to just bail out. For some applications and some users, this "just updating the UI" case is the primary use case for completion handlers.
