Bind multiple cancellables to the lifetime of another object like your view controller.
Import Cancellor and subscribe your publishers inside an ownedCancellables block. When your view controller is dismissed any active subscriptions will get cancelled automatically.
import Cancellor
class MyViewController: UIViewController {
override func viewDidLoad() {
ownedCancellables {
myPublisher1.sink(...)
myPublisher2.sink(...)
myPublisher3.assign(to: ..., on: ...)
}
}
}To tie a single subscription to the lifetime of another object use:
class ViewModel: NSObject { ... }
let vm = ViewModel(...)
...
myPublisher
.sink(...)
.owned(by: vm)Add the following dependency to your Package.swift file:
