Using 'self' on RxSwift closures… What about instance methods as param?

Question

In other stack overflow questions, it was emphasized that the capture [weak self] should be used for closures that aren\'t owned by the class because self

Answer 1

Unfortunately, passing an instance method to subscribeNext will retain self. To be more generic, storing a reference to an instance method will increase the retain count of the instance.

let instance = ReferenceType()
print(CFGetRetainCount(instance)) // 1

let methodReference = instance.method
print(CFGetRetainCount(instance)) // 2

The only solution here is do what you have done in unownedDisplayPeople.

let instance = ReferenceType()
print(CFGetRetainCount(instance)) // 1

let methodReference = { [unowned instance] in instance.method() }
print(CFGetRetainCount(instance)) // 1
