I need to perform a segue to a modal from my tabbar controller. This won't work since there's a starting tab that overrides the modal segue (I think. The modal won't show). And I can't perform the segue in the starting tab since different product targets have different starting tabs and it would be messy having the same code in multiple places.
Anyway, I solved it by using
NotificationCenter.default.addObserver(self, selector: #selector(applicationDidBecomeActive), name: UIApplication.didBecomeActiveNotification, object: nil)
@objc func applicationDidBecomeActive(notification: Notification) {
performSegue(withIdentifier: "Segue", sender: nil)
}
It works great. But, I don't want to use this old @objc code. Isn't there a mode modern swifty way to do this? I'm fine using UIApplication.didBecomeActiveNotification, but I want to get away from using the #selector and @objc.
If you are targeting iOS 13+, you can use Combine to observe NotificationCenter notifications without having to use selectors. The publisher(for:) function of NotificationCenter can be used for this.
var subscriptions = Set<AnyCancellable>()
let notificationPublisher = NotificationCenter.default.publisher(for: UIApplication.didBecomeActiveNotification)
notificationPublisher.sink { _ in performSegue(withIdentifier: "Segue", sender: nil) }.store(in: &subscriptions)
