How do I avoid retain cycles with closures and properties in Swift?

In Swift, retain cycles can occur when a closure captures a reference to an object that also retains the closure, leading to memory leaks. To prevent this, you can use a weak or unowned reference to self within the closure. This approach ensures that the closure does not strongly capture self, allowing it to be deallocated when it is no longer needed.

Here is an example of how to avoid retain cycles in Swift using a weak reference:

class MyClass { var closure: (() -> Void)? func setupClosure() { closure = { [weak self] in guard let strongSelf = self else { return } print("Strong reference to self: \(strongSelf)") } } }
