We encountered a weird situation recently. Our daily build process upload an app with a daily incremental 4-digit build number, e.g. 4000, 4001, 4002, etc. Our release build number has a specific requirement to use the date, such as 20240719. In the past I have learned that in order to upload a new build for the same version number, the new build number needs to be greater than the old one. Thus, if I have uploaded 200.1.0 (20240719), I cannot upload 200.1.0 (4001) anymore, because the daily build's build number is smaller than the release build. I have to expire the 20240719 build in order for the daily build to continue, which is fine. The problem is, yesterday I submitted 200.1.0 (20240719) for App Store review then got approved. While today's daily build is 200.2.0 (4001) and when it is uploaded, it got rejected for the following error message: This bundle is invalid. The value for key CFBundleVersion [4001] in the Info.plist file must contain a higher version than that of the previously uploaded version [20240719]. Please find more information about CFBundleVersion at https://developer.apple.com/documentation/bundleresources/information_property_list/cfbundleversion With error code STATE_ERROR.VALIDATION_ERROR.90061 for id [redacted] Asset validation failed (-19208) This befuddles me, because the 20240719 build submitted for review is in an older release version, while the daily build 4001 is using the newer release version number. It seems that TestFlight decided to compare build numbers while ignoring the version numbers?! Furthermore, after I canceled my approved submission for 200.1.0 (20240719), surprisingly the 200.2.0 (4001) can be uploaded without an error! 😲 It seems that the only factor is whether the build is submitted or not. If an older version number higher build (200.1.0 (20240719)) is not submitted, then TestFlight happily allows newer version number lower build (200.2.0 (4001)) to be uploaded. In contrast, if submitted, then 4001 is not allowed to be uploaded! Is it an expected behavior? Thank you for the patience.

We are working on a world scale AR app that leverages the device location and heading to place objects in the streets, so that they are correctly and stably anchored to certain locations. Since the geo-tracking imagery is only available in certain cities and areas, we are trying to figure out how to fallback when geo-tracking is not available as the device move away, to still retain good AR camera accuracy. We might need to come up with some algorithm using the device GPS, to line up the ARCamera with our objects. Question: Does geo-tracking always provide greater than or equal to the accuracy of world tracking, for a GPS outdoor AR experience? If so, we can simply use the ARGeoTrackingConfiguration for the entire time, and rely on the ARView keeping itself aligned. Otherwise, we need to switch between it and ARWorldTrackingConfiguration when geo-tracking is not available and/or its accuracy is low, then roll our own algorithm to keep the camera aligned. Thanks.

Description We have a sidebar-detail layout in our app. Since we moved from NavigationView on iOS 15 to NavigationSplitView on iOS 16, we've seen some issues. On iOS 16, the app is always killed, or reset, when the app enters background. That means whatever the sidebar and detail view show, they will almost always return to the initial blank screen state when coming back from background. On iOS 17, the background issue is mitigated. However, the toolbar button is missing after coming back from background. Those problem aren't present in NavigationView on iOS 15. Steps to Repro General steps… Create a new iOS app demo project with deployment target min version set to iOS 16. Copy and paste the code snippet below into ContentView.swift. Run the app on iPad simulator with the respective Simulator OS versions. iOS 16 Tap the info button on the side bar, it presents a "form sheet" style page. Put the app into background. Open any app. I opened the Photos app. Switch back to the demo app. The sheet is dismissed and the app returns to the initial state, which indicates the app was reset in the background. When I tap the info button again, it doesn't present a sheet. iOS 17 Same steps as 1-3 above for iOS 16. Switch back to the test app. The sheet is not dismissed, which means the app wasn't reset in the background. However, you can see the info button is missing from the sidebar's top toolbar.

Description I've seen this issue when I use WKWebView in SwiftUI. If I have 2 web views at once in a SwiftUI view, it produces unwanted console warnings that seem to be not solvable on client side. The warnings aren't present when there is only 1 web view. Similar warnings regarding the "running board" or RBSAssertionErrorDomain are reported by others as well. Please advice how to dismiss these warnings in the app. Thank you. Repro Steps and Code Create a new iOS project. Put the following code into ContentView.swift.

Before iOS 17 beta, the .pickerStyle(.segmented) modifier makes the Picker take up the entire available width in a toolbar. In iOS 17, it tightly fits the width of the text. I can use .fixedSize() modifier to make the segmented control tightly fit the content. In reverse, what is the recommended way to make it expand to fill the whole width? In iOS 17 beta, I tried .frame(idealWidth: UIScreen.main.bounds.width) and it works, but it doesn't have effect in iOS 16 and prior. Also, it is semantically wrong to set the ideal width to an arbitrary big value. Example: iOS 16, full iOS 17, tight
