I have encountered a tricky problem and hope to receive help. My APP process does not exist, and then I click on the notification message of the APP to open it. At this time, my APP will first configure uitabbarccontroller, and then push the first (index=0) viewcontroller (A) from the tab to the notification message list viewcontroller (B). However, I found that on iOS18, the lifecycle of A (viewDidLoad) did not execute at the end of this process. I am sure this problem will occur stably on iOS18.1.1. Versions lower than iOS18 will not. Can someone tell me why this is?

I encountered an issue while using the AlertController. When I added two buttons (cancel, confirm), they were arranged left and right. When the word count of the two buttons was high, they became arranged vertically. I would like to know what changes this adaptive arrangement is based on? Or, when the word count of a button exceeds a certain limit, it will become arranged in a top and bottom sequence? I did not find any explanation about this in the development documentation. I hope someone can help me. Thank you very much.

I have discovered a strange phenomenon about iOS18.1.1. I set a logo as the titleView in my navigationBar, and then when I added a view to the navigationBar and pushed it to another page before popping it back up, I found that the view hierarchy of the navigationBar would change in a very short time. In this short time, the logo would cover the view. I did not find this phenomenon on devices below iOS18.1.1. I would like to know what changes have occurred in iOS18.1.1 that caused the view hierarchy to change during the pop process. I hope someone can help me. Thank you very much

I am an iOS development engineer. Recently, I updated the Xcode version to 16.1 (16B40) and updated my debugging device (iPhone 15) to iOS 18.1.1. However, I found that I could not respond to the delegate method. I confirmed that my code, certificate, Xcode settings, and network environment had not changed. Simply executing application.registerForRemoteNotifications() in func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool did not receive a response(didRegisterForRemoteNotificationsWithDeviceToken or didFailToRegisterForRemoteNotificationsWithError ). In the same environment, when I switched to another device for debugging (iOS 17.0.3), the delegate method would respond. I really don't know what to do, I hope someone can help me, I would be very grateful. Please note: Everything is normal when using devices before iOS 18.1.1 version
