Am trying to get away from using UIPageViewController for a number of reasons, not the least of which is several perennial crashes that happen occasionally that I've never been able to reproduce myself but happen enough in the wild to be noticeable. I have high hopes for the new UICollectionViewCompositionalLayout in iOS 13 SDK; have worked around the safeArea issue. However, I cannot find a way to workaround or fix the problem that occurs when I rotate the device. Before rotation things are great, paging works, etc. Then when I do rotate the device the collectionView is scrolled such that I see half of two separate cells. Basically the current cell is not handled correctly. Any ideas or suggestions? Below is my layout for reference. Its as basic as one can get.     private func createLayout() -> UICollectionViewLayout {         let itemSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1.0), heightDimension: .fractionalHeight(1.0))         let item = NSCollectionLayoutItem(layoutSize: itemSize)         let groupSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1.0), heightDimension: .fractionalHeight(1.0))         let group = NSCollectionLayoutGroup.vertical(layoutSize: groupSize, subitems: [item])         let section = NSCollectionLayoutSection(group: group)         section.orthogonalScrollingBehavior = .groupPaging         let layout = UICollectionViewCompositionalLayout(section: section)         return layout     } }

I see that many accessibility features have been added to the SwiftUI API, but I am unable to find support for LargeContentViewer on custom views. Is it perhaps going by a different name? Is it really not supported yet in the latest SwiftUI implementation?

I am starting to use CLLocationButton in my apps, but can see an issue with its behavior. When the user taps on a UIButton it is visually noticeable that it's being tapped. Color/Alpha change, image adjusts, etc... When the user taps on a CLLocationButton there is no queues as to it being pressed. I've had several test users complain already that they think the button is not working given that the action might not result in an immediately change to the UI.

I am attempting to utilize the new SWAttributionView in SwiftUI since I am adding SharedWithYou support to one of my apps. Below is the UIViewRepresentable I created to wrap the UIKit component. I have tried many combinations of view modifiers, but have not figured out how to get the height to be just what's needed. My goal is to pin the view near the bottom trailing edge of the view containing it. If I do the same UIViewRepresentable wrapping a UILabel, for testing purposes, I can simple use .fixedSize on it and a Spacer() to get the vertical effect I am looking for. struct AttributionView: UIViewRepresentable {     var highlight: SWHighlight     func makeUIView(context: Context) -> SWAttributionView {         SWAttributionView()     }     func updateUIView(_ uiView: SWAttributionView, context: Context) {         uiView.highlight = highlight         uiView.backgroundStyle = .material       uiView.horizontalAlignment = .trailing         uiView.displayContext = .summary     } }

I just want to see if anyone has worked around the following issue. I did file feedback at FB11405641. Using Apple's demo app from WWDC, if I open the LookAround when on an iPad in either split screen or using Stage Manager the full screen representation is not respecting the actual size of the window. See Here are some videos showing the issue: https://www.hotngui.com/tmp/SplitScreen.mov https://www.hotngui.com/tmp/StageManager.mov

For the life of me I cannot find any documentation that explains the limits of how much space an app can use in the Public and Private database. How to get more Public space, and how to know we need to ask the user to get more iCloud storage for their private database. Any pointers appreciated...

I want to use a NSCollectionViewDiffableDataSource with the newish UICollectionLayoutListConfiguration, but I have a requirement that when deleting a cell it needs to animate out from the right; ditto for when inserting items. However I see no way to control the animation. I know that the UITableViewDiffableDataSource has the defaultRowAnimation property that can be set to affect the animation - Is there an equivalent approach to controlling that of the UICollectionViewDiffableDataSource?

I have a designer asking how popular dark mode usage is among iPhone users. Are there any legit statistics available on the subject that someone (may Apple) can point them to?

I love the new UIImage(resource:) initializer that uses the automatically generated symbols for my image assets. However, there does not appear to be an equivalent in SpriteKit so I am forced to still use SKSpriteNode(imageNamed:) I am using Xcode 15 Beta 7. Will this be included when Xcode 15 goes into production?

Am looking to finally updating some old code now that we are dropping iOS 15 support and want to move to the new mkMapView configurations such as MKHybridMapConfiguration. However when I use that configuration I cannot get it to show traffic conditions, even though I am setting showsTraffic = true Bug, feature, dumb coding error on my part?

Am tired of asking my boss to forward me the emails they get from Apple with the subject "The uploaded build for XXXX has one or more issues." I am trying to debug issues such as ITMS-91053: Missing API declaration as we deal with our 3rd party package usage. What permissions, privileges do I need to get those emails?

I am trying to get the playbackStoreID via the MPMediaPickerController so I can play songs in my app. For many songs I can see and select I am getting a value of "0" for the playbackStoreID on the returned MPMediaItem. Now if I use the "Music" app I can play those songs, but since the playbackStoreID is "0" I cannot successful get them in the queue for a MPMusicPlayerController.applicationQueuePlayer What's the deal? How do I get a proper ID that I can use to get those songs played? If I cannot, how can I hide those songs from the MPMediaPickerController so a user does not think they can play those songs in my app?

Am in the process of migrating some UIKit based apps over to SwiftUI, but for the life of me I cannot find the SwiftUI equivalent of Readable Content Margins. I have come across some workarounds that kind of, sort of work, but do not produce the same results when compared to running the same user interface written using UIKit on several sizes of iPads in portrait and landscape orientiations. is it something Apple has not gotten around to yet, because I realize SwiftUI is a work-in-progress, or do we not care about creating consistent readable margins in our apps anymore?

I have a UICollectionViewDiffableDataSource that has its supplementaryViewProvider property set to a closure that returns a header view for the cell. The closure is only getting called for the first section of the collectionView regardless of the number of sections there are, each of which do contain cells. I am using Xcode 13 beta 5.

I did see a checklist in another post (see below) that I did verify as being configured correctly, but my delegate never gets called. I have confirmed that my universal link is working correctly as tapping on it in Messages does cause the app to open and handle it by going to the appropriate screen. A couple of details: My universal link is new and am testing it using Developer -> Associated Domains Development I am rewriting my app using SwiftUI including @main being a struct derived from App What else am I missing? is Shared with You enabled for your app? Preferences > Messages > Shared with You and see if the toggle for your APP is enabled? is Shared with You enabled for the conversation where these universal links are shared In the conversation where the universal links are shared, is the participant a Contact? If you have sent the link, then you will need to "Pin" the link for it to surface in Shared with You.
