Irregular heartbeat.It is a known fact that, if X is Banach and C ⊆ X is a strongly closed convex set, then C is also weakly closed. The proof goes like this: Pick x0 ∉ C. {x0} is compact and C closed, they're both convex, so by Hahn-Banach there is f ∈X′ which separates the two strictly, that is, f(x) < α < f(x0) for some α ∈R and all x ∈ C.This is really only for the handful of times when weak would cause annoyances to use, but even when you could use guard let inside the closure with a weakly captured variable. If you have a strong reference cycle situation – where thing A owns thing B and thing B owns thing A – then one of the two should use weak capturing.In Swift, there are two ways to capture self as a strong reference within an escaping closure. The first is to explicitly use the self keyword whenever we’re calling a method or accessing a property on the current object within such a closure. For example, the following VideoViewController performs such a strong capture in order to be able to ...Before Swift 4.2, which implemented SE-0079, we would have to do something like: someTask { [weak self] result in guard let strongSelf = self else { return } strongSelf.xxx = yyy strongSelf.doLongTermWork () strongSelf.finish () } You can see why we prefer the Swift 4.2 improvement, as this strongSelf syntax is inelegant.Nick, I like where you’re headed with the instance-methods-as-closures idea. Here’s where I’m headed with it: Closures are too often used to write the contents of what should be another function, producing code similar to the “pyramid of doom” avoided by guard. I now generally write as little code as possible in a closure, and use it merely to dispatch out to a private function as ...Weak entities are represented with double rectangular box in the ER Diagram and the identifying relationships are represented with double diamond.

This concept, although seemingly simple, can be a game-changer in how you structure and organize your Swift code. Defining Escaping ClosuresIt is a known fact that, if X is Banach and C ⊆ X is a strongly closed convex set, then C is also weakly closed. The proof goes like this: Pick x0 ∉ C. {x0} is compact and C closed, they're both convex, so by Hahn-Banach there is f ∈X′ which separates the two strictly, that is, f(x) < α < f(x0) for some α ∈R and all x ∈ C.Apr 24, 2019 · Whoa, hang on. I think it's a jump to say [unowned self] is safer than [strong self], and [weak self] + guard + return definitely isn't safer because it leads to silently ignoring results (and silently ignoring failures). I'm really curious what cases you all are using [weak self] with so much that you want sugar for it. [unowned self] I get because you want to avoid reference cycles, but ... Closure may sometimes give someone a feeling of control where there wasn't one before, and it may provide a stronger foundation from which one can take action and move forward.

By declaring it weak ...WebIn the above example, I happened to use [weak self] in imageTask closure, not because I was worried about any strong reference cycle, but simply because a network task generally has no business claiming a strong reference over the model object.

It has to do with the reference to the observed instance inside the function being weak. It is up to the caller to say weak self, just as you said; there is no magic way around it (certainly making the reference to the function weak is not a magic way around it). –WebClosures: Anonymous Functions that Capture Their Environment.
