I am a developer on an enterprise application. Our team just updated our pipeline to build our app on the iOS 18 SDK instead of the 17.4 SDK and this has caused a lot of our ui elements to change and several crashes within the app resulting in just the simple error message "Swift runtime failure: unhandled C++ / Objective-C exception". Why is just updating the SDK causing all these issues? Is there anyway to keep the previous version or will we have to go component by component to fix the constraints and crashes? These issues seem to be happening to our users on iOS 18 and beyond.

Basically the title. I am trying to implement a local notification to trigger, regardless of internet connection, around 3-5pm if a certain array in the app is not empty to get the user to sync unsaved work with the cloud. I wanted to used the BGAppRefreshTask as I saw it was lightweight and quick for just posting a banner notification but after inspecting it in the console, it looks like it needs internet connection to trigger. Is this the case or am I doing something wrong? Should I be using the BGProcessingTask instead?

When I build my app via ios 26 sdk, I no longer see navigation titles on a split view controller. In the view hierarchy, I can still see it but its no longer rendering in the application itself. Any ideas?
