I've been working on a visionOS platform for my existing app. I added the visionOS platform in App Store Connect. In Xcode 15.2, I set the destination to 'Any visionOS Device (Designed for iPad, arm64)'. The App Store Connect visionOS platform does not see the build. It does show up as an iOS build on Test Flight. I don't see anyway to designate the build as a build that the visionOS destination sees. Also, the upload failed when I tried to set the version for the app as 1.0. It went through when I put the version as a number higher than my iOS app version.

The function in question is the following. func records(for ids: [CKRecord.ID], desiredKeys: [CKRecord.FieldKey]? = nil) async throws -> [CKRecord.ID : Result<CKRecord, Error>] Note that the returned value looks like a dictionary of the form [CKRecord.ID : Result<CKRecord, Error>], but the input is an array of CKRecord.IDs. There are similar functions, but they return a tuple. Like the below example. func records(matching query: CKQuery, inZoneWith zoneID: CKRecordZone.ID? = nil, desiredKeys: [CKRecord.FieldKey]? = nil, resultsLimit: Int = CKQueryOperation.maximumResults) async throws -> (matchResults: [(CKRecord.ID, Result<CKRecord, Error>)], queryCursor: CKQueryOperation.Cursor?) Note that matchedResults is an array of tuples consisting of [(CKRecord.ID, Result<CKRecord, Error>)]. I would have thought that the return type in the first function would also be of the form [(CKRecord.ID, Result<CKRecord, Error>)]. What am I missing?

I'm getting this when I go to Accounts on Xcode and click on why Apple ID. I'm getting this on the current version and latest beta of Xcode. It's very disheartening. Anybody know what causes this?

This is probably a simple question, but how can one have scrolling in one's Apple Watch app like that in the Workout App using SwiftUI? The scrolling which emphasizes each item as it scrolls by. I'm trying to recall, but can't.

I've been playing around with ARKit and I am interested in the orientation of ARGeoAnchor, ARImageAnchor and ARFaceAnchor. First of all, I notice that Apple says that ARGeoAnchor is based on an East-North-Up orientation, with its x- and z-axes matching the longitude and latitude directions. This should actually be characterized as an East-Up-South orientation (see https://developer.apple.com/documentation/arkit/arconfiguration/worldalignment/gravityandheading). I created an image to illustrate my point. It's the ferry building. Referring to the ARKit 4 presentation (wwdc20-10611), one can see that the 'Ferry Building' label is initially facing south and needs to be rotated by approximately -51.4 degrees about the y axis in order to face in the proper direction. As far as ARImageAnchor is concerned, it appears to me that the coordinate system is as in the below image. This is surprising to me as I would have expected it to be x to the right, y pointing up in the image and z pointing out of the image. It appears that ARPlaneAnchor's orientation is the same as ARImageAnchor. As far as ARFaceAnchor is concerned, its orientation is clearly explained in https://developer.apple.com/documentation/arkit/arfaceanchor and the orientation seems consistent to me. I wish that the other anchors were explained as well. Anyway, feel free to chime in with corrections and comments.

I'm using my Mac and have macOS 13.0. I searched for 'Vinyl Record Shops' and 'Search Nearby' with Private Relay Enabled and the Map moved to Denver, Colorado while I am in Orlando, Florida. When I disable Private Relay, the search did take me to Orlando, Florida, but when I disabled it just now, it took me to Dallas / Ft Worth. I have 'Maintain General Location' selected. I don't have this issue with iOS 16.1 on my iPhone. Anybody else have this problem?

I have burned the midnight, no, 2 AM oil to knock out the ton of Sendable warnings on my app. I have worked the issues, but have two functions remaining where I am stuck. The functions are both CloudKit functions. One of them is shown in the image. I am at a loss on how to clear this warning. Any amount of help would be most appreciated.

I am working on an update to one of my apps. The app uses CloudKit and utilizes the Public and Private databases. The user data is stored in the Private database. I have created methods to convert from CKRecords of the user's type to Codeable Structs and encode in json format and decode the json data into the array of Structs. I also have a method to create a CKRecord of the user's type from the Struct data. I am working on giving the user the option of replacing the CKRecords in the cloud with CKRecords created from a json file. I have a method which deletes all of the CKRecords followed by a method which uploads the CKRecords created from the json data. If I wait a while after this operation without using the app, it works well. But if I try to access the saved CKRecords shortly after the methods are executed, I have mixed results. Sometimes, I get less than what I uploaded and sometimes I get more than what I uploaded. I use try await on both methods and use the return value of the first method (delete) as an input into the second method (upload). Both the delete and upload methods use modifyRecords(saving: saveRecords, deleting: recordIDs, savePolicy: .allKeys, atomically: false) I do not use the modifyRecords method to do both at the same time. I use two modifyRecords methods. In all cases, the results show that the operations completed successfully even when there was an issue. I'd like for the delete method to delete all of the data and for the upload method to upload all of the json data without requiring an excessive delay.. Any advice would be most appreciated.

I have SwiftData and CloudKit working on a new version of my UIKit app. The current version uses CoreData/CloudKit I have a question. How does one know when there there is new or deleted data to update a view in a UIKit app with SwiftData? CoreData has NSPersistentStoreRemoteChangeNotificationOptionKey. What does SwiftData have that's equivalent? It's not feasible to redo my whole app to use SwiftUI at this stage.

I have modified two of my apps to run on visionOS and I see that in App Store Connect, one add a visionOS Platform. My question is, why would I want to do this if I can't upload a visionOS binary? Would it be to work on the metadata? Also, I would like to have my visionOS binary evaluated. Is there any way to do this at this time? It appears that only iOS or iPadOS apps are being evaluated.

modelContext.fetchIdentifiers(descriptor) errors when using a SortDescriptor to sort by a variable and returns no models. The fetch works fine without a SortDescriptor, thus FetchDescriptor<MyModel>() works fine, but FetchDescriptor<MyModel>(sortBy: [.init(\.title)]) or FetchDescriptor<MyModel>(sortBy: [SortDescriptor(\.title)]) errors with console message The operation couldn’t be completed. (SwiftData.SwiftDataError error 1.) I am using Xcode Version 16.0 beta 6 (16A5230g).

I have two apps in which I have fixed warnings on Sendable, however there's one app where I did not and it looks like the rent's come due with Xcode 26.0, as I am getting over 100 warnings about Sendable. On a lark, I let the AI work on the warnings. There were so many that I ran out of free ChatGPT time and had to wait 24 hours. But today I cleared every remaining warning, but did the app still work? I figured I'd have to trash this code and do it by hand. But to my surprise, the app is working properly so far. More testing needs to be done and I need to dig into the code to make sure it's right, but so far, so good.

Anybody converting from CKQueryOperation to the new CloudKit async await methods? If so, what do you think? I'm currently playing with func records(matching query: CKQuery, inZoneWith zoneID: CKRecordZone.ID? = nil, desiredKeys: [CKRecord.FieldKey]? = nil, resultsLimit: Int = CKQueryOperation.maximumResults) async throws -> (matchResults: [(CKRecord.ID, Result<CKRecord, Error>)], queryCursor: CKQueryOperation.Cursor?) and func records(continuingMatchFrom queryCursor: CKQueryOperation.Cursor, desiredKeys: [CKRecord.FieldKey]? = nil, resultsLimit: Int = CKQueryOperation.maximumResults) async throws -> (matchResults: [(CKRecord.ID, Result<CKRecord, Error>)], queryCursor: CKQueryOperation.Cursor?) They seem to work fine and eliminate completion handlers.

I want to move an Entity in from the right programmatically, but the move function is not working. I am using image tracking. I can place the entity statically, so I know I'm detecting the image. Here is my function. func placeMyPictureEntity(imageAnchor: ARImageAnchor) {         if let entity = try? Experience.loadMyScene() {             entity.scale = SIMD3(0, 0, 0)             let imageAnchorEntity = AnchorEntity(anchor: imageAnchor)             imageAnchorEntity.name = imageAnchor.name!             // Position the entity to the side             let anchorWidth = Float(imageAnchor.referenceImage.physicalSize.width)             entity.setPosition(SIMD3<Float>(x: 20.0*anchorWidth , y: 0.0, z: 0.0), relativeTo: imageAnchorEntity)             let newTransform = Transform(scale: SIMD3(20.0, 20.0, 20.0), rotation: simd_quaternion(0, 0, 0, 1), translation: SIMD3(x: anchorWidth, y: 0.0, z: 0.0))             entity.move(to: newTransform, relativeTo: imageAnchorEntity, duration: 2.0, timingFunction: .easeIn)             imageAnchorEntity.addChild(entity)             // Add anchor to scene             arView.scene.addAnchor(imageAnchorEntity)         }     } Any help would be most appreciated. Thanks.

Anybody else come from an Aerospace background? In aerospace, the vector is stationary and the frame is rotated, for the most part, whereas here, the frame is stationary and the vector is rotated. Opposite rotations. It would be nice to have one document which discusses all of the reference frames with cartoons showing the axes. The Ferry Building example helped me a great deal when I looked at a map of the Ferry Building area and realized that the cardinal axis that location anchors are pretended is South (along the z axis). Makes sense. That's why it needed to be rotated by -51.4 degrees.
