Hi,I have a very weird situation. My iMessage App icon is showing well on all iPhones, but not iPad. All icons are generated automatically by sketch in different sizes.I even replaced all icons with version I created using photoshop.I verified all sizes.The icon is in the final binary but is not showing in the list of iMessage apps, instead I see the generic icon with our app name.https://itunes.apple.com/us/app/wit-what-is-this/id1152446245Any idea where this could be comming from? Any resources I could check?All the best Christoph

Hi guys,I am creating MTL Textures from CIImages. Everything is sRGB, but when it shows up in Scene Kit it looks white too pale, like the data is used as RGB.I am using no lights nothing in the scene, it's purely a scene with SCNPlanes having the textures as diffuse material and a camera that is it. No lights nothing.Any Ideas what I can do to get a normal representation?(Below a picture of the CIImage in the small window and in SCNViewAll the bestChristoph

Hi,I want to allow the user to choose wether a document is opened or auto processed when opened from the outside.When currently a document is opened with the app it always opens a document window, not calling the AppDelegate's application:openURLs:So the question is:How do I detect when a file is opened• via Finder "Open With" or• dragged onto the Dock iconwhile bypass when• Recent files is used or• File -> Open / The Open Panel• a document is reopeend• a document is duplicated etc.or any way that is clearly meant to open a doucment window.I have tried overwriting the NSDocumentController, but the open method here does not allow me to distinguish why the file is opened. In NSApplication all document related tasks are in the NSApplication(NSEventHandling) extension and cannot be overwriten, and the actual open event is triggerd by nextEventWithMask:… and intercepting that seemes kind of hackish and cannot be the approach Apple designated for this situation. (especially since the Events are not even well documented :-(Any tips?All the best Christoph

Hi,as all Photos Project Extension, mine comes with an app.How do I open my Photos Extension in Photos directly from my app?Is there an Photos URL Scheme I or open a url to open my extension? All the best Christoph

Hi, I tried to bring an app to macOS using Catalyst, but have troubles with CloudKit. Basically what the app does is, it writes records to the public database and allows to retrieve that data via the recordID. Simple and straight forward and of course the code has been working for iOS for years now. On macOS I can upload data, but when I try to receive data I get nothing, as if the request was never started. I do not get gate back, nor any error, not even a time out. Could anybody give me a hint where to look for a solution? All the best Christoph

Hi, I am already confused about getting the regions of interest on Mac (I am getting them through the project info sections which makes no sense to my, why is a region of interest dependent on the project and it seems bug prone as the section are slowly updated after assets are added). How do I get the region of interest of a PHAsset on iOS? And is that approach portable to macOS? All the best Christoph

Hi, I have been rejected because my App links against MapKit, but does not use it. I verified and otool -L finds this @rpath/libswiftMapKit.dylib (compatibility version 1.0.0, current version 2.0.0, weak) But I have no idea where this comes from • it is not in my list of linked Libraries • MapKit is not appearing anywhere in my Code (no "import MapKit" or anything) • I don't use any thing that starts with an MK • I do not include or link against non Apple Libraries What I do have is • a 5.3 Swift code except for • Zip Library and for it linker flags -lz and -liconv What could trigger the linking against MapKit? How can I isolate this problem? I am truly stuck and could use some pointers. All the best Christoph

Hi, I have multiple idea for a GeoTracking AR apps using ARGeoTrackingConfiguration, but noticed the list of cities are all in the US. My personal hope was that all cities with 3D data would support this sooner or later, but this has not happened for me yet. Is there any way for testing/faking this to know what the user will experience? How fast is it expanding, so would it be worth waiting till it's available in my areas (Düsseldorf, Germany), too? All the best Christoph

Hi, I have embedded a view into a scroll view in case the content is too large, but mostly it is not. Is there a way to have the ScrollView shrink to fit its content? To my surprise it looks like this is a simple task not possible in SwiftUI? Am I missing something? All the best Christoph

Hi, I am using SCNConstraints to zoom in on a geometry the user clicked, but would like to reset to my original position when the user clicks outside. How do I reset my Camera to its original position? I read constraints are changing the transform, but the position, transform and everything is unchanged. Yet when I set constraints = nil nothing happens the camera stays where it last was and does not move and everything it contains claims a different position. even the world transform shows it's unchanged. How do I reset a camera node to it's origin after I removed all constraints???

Hi, I wanted to offer the UI for editing and deleting a share. So for using UICloudSharingController(share: , container: ) I implemented the delegate to call "persistUpdatedShare" in "cloudSharingControllerDidSaveShare" func cloudSharingControllerDidSaveShare(_ csc: UICloudSharingController) { if let share = csc.share,   let privatePersistentStore = PersistenceController.shared.privatePersistentStore { PersistenceController.shared.container.persistUpdatedShare(share, in: privatePersistentStore) { (share, error) in Thread.performOnMain { if let error = error { PersistenceController.shared.storeWarning = error } } } } } and to call "purgeObjectsAndRecordsInZone" in "cloudSharingControllerDidStopSharing" func cloudSharingControllerDidStopSharing(_ csc: UICloudSharingController) { let puzzleToShare = puzzleToShare if let share = csc.share,   let privatePersistentStore = PersistenceController.shared.privatePersistentStore { PersistenceController.shared.container.purgeObjectsAndRecordsInZone(with: share.recordID.zoneID, in: privatePersistentStore) { (zoneID, error) in Thread.performOnMain { if let error = error { PersistenceController.shared.storeWarning = error } else { puzzleToShare.makePrivateDuplicate() try? puzzleToShare.puzzle.managedObjectContext?.save() } } } } } I got this implementation from a TSI, but it makes no sense to me to delete and duplicate my objects rather than just keeping them and only deleting the share. Question: How can I cleanly discontinue a share, but keep my data. Duplicating my objects seems such a weird approach. But without this implementation it does not really work. (I get strange behaviors and crashes) All the best Christoph

Hi, when working with SwiftUI @Published variables need to be set from the main thread, but at the same time, cannot be defined as @MainActor. The easy solution is a simple forced sync or async execution on the main thread, but it seems like this does not exist in the world of async/await and Tasks - at least I did not find it. Instead I found that all demo's from Apple is a quite sad solution. The full method is marked as @MainActor even though this is often only relevant for the last line. The question is either that I can execute a setter on main only OR that I can mark my SwiftUI code as being on main and thus being able to accept @MainActor @Published Is there really no solution? If so where do I have to propose/request a solution for this. I feel like every developer had written his own version of Thread.performOnMain, but here I want something using Task and that the compiler can verify. All the best Christoph

Hi, I have a look to wait for all non purchase Transaction             for await result in Transaction.updates { … } But this block works when I trigger a restore purchases, but it is never called when I approve a pending purchase. Is there any reasoning why this could be or a bug. (As an app store user and father I had a similar problem where my daughter had to tap purchase again and then it worked. All the best Christoph

Hi, I always though @FetchedResults should automatically update, but it seems this is not always true, or do I have to trigger updates myself? I am using Core Data with CloudKit sync. When I start my app, nothing is visually updating while it'S doing the first sync. Only after that view is reloaded it shows the synced data. Any idea what I have to do automatically get updates when the data is syncing the background. All the best Christoph

Hi, I get nicely creased USD models from my 3D designer which are super small, as higher meshes can be generated from them and even normals can be derived from these models. Question is: Does RealityKit automatically … • … generate the normals from the crease information? • … subdivide for these models (do I have to/can I set a subdivision level)? • … generate subdivision in the GPU as the model get's closer to the camera or should I even force create multiple detail levels?
