Overview

Hi everyone, I’m a mixed reality designer currently building visionOS experiences (RealityKit + SwiftUI), and I’m working on a course at Arizona State University where we develop a project in response to a real-world client. I’m looking to collaborate with someone in the visionOS ecosystem who would be open to sharing a simple prompt or brief (nothing confidential), which I can use to create a proposal response. The outcome would include: Spatial concept + storyboard Interaction design direction Rough scope, timeline, and team structure Optional small prototype in visionOS The goal on my side is to better understand how spatial work is framed and communicated in real-world scenarios, especially within Apple’s ecosystem. The ask is very lightweight: 1–2 short check-ins during April or async feedback via email A bit about my work: Built Spatial Synesthesia for Apple Vision Pro Eye tracking interaction that isolates instruments in a live orchestral mix based on color perception Working with computer vision and spatial anchoring in Unity and visionOS Focused on perception-driven interaction and minimal UI systems If you’re a developer, designer, or part of a small studio working in visionOS and this sounds interesting, I’d love to connect. Thanks in advance. Leo

Hello, I released a new build for my app but it fails to run on iOS 12.5.8 (tested on iPad Air, iPhone 6, iPhone 5s). The launch storybard is shown, then the app stops abruptly. There is no crash log. It runs fine on iOS 13 or higher. Xcode 26.3 was showing a call stack (something with UIView) that did not include any app code. Now with Xcode 26.4 (and its new command line tools) there is an info popup with a debug metadata dump. However, I don’t intend to focus on Xcode here because it officially does not support iOS 12. It’s ok if I cannot debug, I just want the app to run on the device like the previous build did. Since there is no crash log, and the console is showing a bootstrap error, I believe my app code has not been executed and is therefore not at fault. Build 674 released on 23-Mar-2026: worked fine on iOS 12, built with Xcode 26.3 Build 675 released on 29-Mar-2026: Bootstrap error as described, with both Xcode 26.3 and 26.4 Deployment target = 12.4 Tried Instruments but it fails as soon as I hit record. In the console I found BKSProcessErrorDomain code 1. Here on the forum I found a post where the cause was no internet access but my device does have internet access. I made only very little code changes to my app between 674 and 675, no storyboard updates. I get the impression the loader does not even begin to execute my code. At this point I wonder if: some certificate has expired (see release dates above), or if something is incompatible in my main storyboard (though I did not change anything there), or the device ran out of memory (1 GB) Note: The app has 4 targets: main app target framework AU app extension intents app extension Thanks, Sven PS: Misclicked subtopic which should have been General (sorry).

I am trying to find out about the availability of BLE scanning for advertisements when a watchOS app (on watchOS 26.4 with CoreBluetooth) which starts running a HKWorkoutSession becomes dimmed, ie. due to the user lowering their arm. From my understanding there is still availability for ongoing scanning whilst in the dimmed mode. If this is correct, what settings are required (e.g. using background capability for 'Workout Processing', 'bluetooth-central', etc), and does scanning whilst in background mode limit to requiring service uuids in scanForPeripherals? Also if scanning is throttled, is there an 'estimated' inter scan time? Thanks

I have an app version (1.2.1) in App Store Connect that is showing "Ready for Review" status. It has an old build (1.2.0, build 4) attached to it. I uploaded a new build today (1.2.1, build 5) and need to swap it in, but there is no "+" or "-" button in the Build section of the version page, and clicking the current build number just navigates to its metadata page. I have tried: Creating a new version (1.2.1) — it auto-populated with the old build Uploading a new build with the correct version string — still no option to swap Looking for a "Remove from Review" button — it does not exist on my page Is there a way to detach the current build and attach the new one, or do I need to delete the version and start fresh? If so, will that affect my existing review thread with Apple? Any help appreciated.

I have a simple reproducer here: struct ContentView: View { @State private var isOn = false @State private var isPresented = false var body: some View { NavigationStack { Color.blue .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Press here") { isPresented = true } .popover(isPresented: $isPresented) { Color.green .frame(idealWidth: 400, idealHeight: 500) .presentationCompactAdaptation(.popover) } } } } } } When I tap on the button in the toolbar you can see there is a hang then the popover shows. Then every time after there is no longer a hang so this seems like a bug. Any ideas? I'm using Xcode 26.3 and a iPad Pro 13-inch (M5) (26.4) simulator.

Hi. Your Contact Us page has been down for at least 2 months. There is no way to contact you. I'm locked out of my Apple Developer Account. What can I do here? I'm also shocked that a company as big as Apple has not fixed this page yet. It's kind of crazy.

Hi, I'm using Bitbucket for remote repository. I try to change the Bitbucket App Password used so far to the remote repository with the new API token with scope as the App Password will be deprecated.. I created the API token successfully but I cannot configure it in Xcode. Does someone has already successfully replaced the App Password with the new API token in Xcode? Thank you in advance Jean MacBook Air 26.3.1 Xcode Version 26.4 (17E192)

Hi. I have a universal app in the AppStore. Can I drop the Intel support and build the app as M only and still have it distributed in the app store? This was a problem the last time I set up my build environment but I am not sure if that is still the case. Regards

Hi all, I’m trying to determine whether the loudness gap I’m seeing between AlarmKit alert playback and normal app-managed playback is expected behavior, a sound-asset issue, or something that should be reported as a bug. Observed behavior When an alarm fires through AlarmKit while the device is locked, the alarm sound is significantly quieter than playback of the same or very similar audio once the app is active and using its own audio session. The difference is large enough that it does not feel like a small mastering difference. It feels like the AlarmKit / system alerting path is using a meaningfully lower effective output level than normal app playback. Test scenario My repro is roughly: Schedule an alarm with AlarmKit. Lock the device. Let the alarm fire and listen during the system alerting phase. Enter the app / continue into the app-driven alarm experience. Play the same or equivalent alarm asset via app-managed playback. Result: AlarmKit / lock-screen alerting phase sounds much quieter. In-app playback sounds noticeably louder and fuller on the same device. Current implementation Alarm flow is currently split into two paths: 1) System alarm path Alarm scheduling and alert surfacing via AlarmKit Device may be locked No attempt to manipulate system volume No private APIs 2) In-app playback path After app activation, playback uses: AVAudioSession category .playback AVAudioPlayer Audio is routed as normal app playback This path sounds substantially louder than the AlarmKit path Important detail I am not asking how to override system volume. I understand that AlarmKit appears to follow the system ringer / alert volume model and does not expose a public API for custom alarm loudness. My question is narrower: Is it expected that the same asset or an equivalent asset will sound materially quieter during the AlarmKit alerting phase than during ordinary app playback with AVAudioSession(category: .playback)? Questions Is the lower perceived loudness during AlarmKit alerting an expected property of the framework / system alarm path? Does AlarmKit playback use a different output path, gain policy, processing chain, or speaker treatment than normal app playback with .playback? Are there recommended authoring constraints for AlarmKit alarm sounds to maximize perceived loudness on iPhone speakers? transient-heavy mix stronger mids reduced low-end different LUFS / peak strategy shorter attack, etc. Has anyone measured this directly with: the same WAV / CAF file same device same system volume locked AlarmKit playback vs unlocked in-app playback If this is not expected, would Apple want this reported as a bug with: sample project exact iOS version device model screen recording / audio recording What I’m trying to figure out For alarm-app UX, this matters a lot because: AlarmKit is the most reliable lock-screen/system path. But if AlarmKit playback is substantially quieter than normal app playback, the alarm experience is inconsistent depending on device/app state. That makes it hard to know whether to treat this as: expected system behavior, a framework limitation, an asset/mastering problem, or a bug. If anyone has tested this in a controlled way or received guidance from Apple/DTS, I’d appreciate any technical detail. Thanks.

Hi guys, Two annoying issues I'm having at the moment with agentic coding. Xcode signs out of Claude every single day and gives the error Failed to authenticate. API Error: 401. The only solution is go to settings and sign out of Claude and in again. Apple removed the little arrow to select the model, so now every time you start a new conversation you have to pick the model. I just want to start a new conversation with the model I'm using. The extra click is a time waster. Any solutions would be appreciated. Thanks

I need constraint the window size for an iOS app running on Mac. That's easy for a MacApp, using self.window?.minSize.width = 450 self.window?.maxSize.width = 450 or use func windowDidResize(_ notification: Notification) { } but how to achieve it in UIKit ?

i want to know if some one is using this to hack me

Hello, I enrolled in the Apple Developer Program and paid on March 11th. Georgian address, Georgian card, Georgian region set on the account. The payment went through 3 times with email acknowledgements each time, but the account is still stuck on "pending." I contacted support by email on March 19th (Case: 102848062117) and again on March 26th (Case: 102853109499), including my phone number. The only visible change since then is that I now have an option to confirm my phone number and get called back, but when I click on it, nothing happens. It just redirects me back to the list of cases I opened. Please escalate so we can resolve the issue.

I have the following code that is attempting to set up Hotspot 2.0 using an EAP-TLS configuration. I am importing a pk12 file and using those certificates. I have tried all manner of permutations for the configuration, and have narrowed down all the errors I was getting and now I am just getting a generic: Error: invalid EAP settings. I have tried adding the identity separately and either get an entitlements issue which I can't figure out why since I have added the required network extension sharing groups, or a duplicate item error, meaning it was already correctly added. The certificate and configuration are correctly working through an Android app already. static let accessGroup: String? = { guard let prefix = Bundle.main.object(forInfoDictionaryKey: "AppIdentifierPrefix") as? String else { print("Could not load group") return nil } return "\(prefix)com.apple.networkextensionsharing" }() static func setupHotspot(data: CertificateData) { let h20 = NEHotspotHS20Settings(domainName: data.realm, roamingEnabled: false) h20.naiRealmNames = [data.realm] var result: CFArray? let options: [CFString: Any] = [ kSecImportExportPassphrase: "**********", kSecAttrLabel: "ident:\(data.user)", kSecAttrAccessGroup: accessGroup!, kSecReturnPersistentRef: true ] let status = SecPKCS12Import(data.p12 as CFData, options as CFDictionary, &result) guard status == errSecSuccess, let importResult = result as? [[String: Any]], let resultDict = importResult.first else { print("P12 Import failed: \(status)") return } let identity = resultDict[kSecImportItemIdentity as String] as! SecIdentity let eap = NEHotspotEAPSettings() eap.supportedEAPTypes = [NEHotspotEAPSettings.EAPType.EAPTLS.rawValue as NSNumber] eap.isTLSClientCertificateRequired = true eap.trustedServerNames = [ data.realm ] eap.outerIdentity = "anonymous" guard eap.setIdentity( identity ) else { print("setIdentity failed") return } let configuration = NEHotspotConfiguration(hs20Settings: h20, eapSettings: eap) NEHotspotConfigurationManager.shared.apply(configuration) { error in if let error = error { print("Error: \(error.localizedDescription)") } else { print("Success") } } }

The production macOS build is showing severe performance problems, while Mac_Dev performs normally. Observed behavior in production Mac build: Issue board scrolling becomes inconsistent or nearly unusable Changing an issue status in detail view is very slow Scrolling the status menu/options can be slow Typing in issue description/notes fields becomes sluggish Dragging issues between milestones/statuses on the board can lag badly Observed behavior in Mac_Dev: Board scrolling is smooth Status changes are immediate Typing in description fields is responsive Drag/drop between milestones works well Important comparison: Mac_Dev appears to run against an isolated local SwiftData store Production Mac app uses the normal CloudKit-backed store Because the same UI is fast in Mac_Dev, this does not look like a pure rendering problem Most likely cause is production store / CloudKit sync churn amplifying existing SwiftUI invalidation and save behavior Current hypothesis: The production app is saving or observing live Issue mutations too aggressively Detail view edits and some quick actions may be causing repeated saves / broad view invalidation Cloud-backed persistence likely makes the problem much worse than the isolated dev store The UI architecture may still need cleanup, but the production data lane is likely a major factor Any help in understanding how best to address this would be helpful.

Hi, We are currently in the process of getting an custom iAP2 device communicating via USB-C. We have been using the 'EADemo' app as a test app to ensure full function before certification. Currently, the device completes the authentication and identification successfully. The device appears within the 'EADemo' app, and we are able to select it and see the available protocol. Selecting the protocol sends the EAStartSession command to the accessory and we ACK it. This is where the issues begin. Attempting to send either a string or hex packet results in nothing being sent. The app does not appear to attempt to send a packet when these are pressed. The 'EADemo' app also does not increment its receive counter when the accessory sends an EA packet, but we do receive the ACK from the device. This indicates the device is receiving the packet, but not processing it in app. Sending the EASessionStatus from the accessory with a status of okay does not change the behavior. Sending the EASessionStatus packet from the accessory with a status of closed results in the device sending an EAStopSession packet. The issue does not appear to be with the accessory or the underlying transport layer. Previous attempts to contact MFi support resulted in them referring me to developer support. Are there any known issues within the 'EADemo' app that we should know about/and or need to fix? Does Apple have any other EA example application? Are there any other publicly avalilbe EA examples that Apple would recommend us trying? Thanks, Mike

I’m using MFMailComposeViewController to send emails from my app. Since updating to iPadOS 26.4, there is no way to cancel the mail composer because the “X” button in the top-left corner has disappeared. On iPhone with iOS 26.4, everything still seems to work as expected. Is this a known issue, or am I missing something? Has anyone else experienced this, or found a workaround?

I have an application that includes custom artwork for the album cover and text details setup with the MPRemoteCommandCenter.shared() reference. I need the user to have a full featured "now playing" display to see all of this. My experience is that cannot find a set of parameters for AVAudioSession.setCategory() that route audio successfully, and display the full featured now playing deck. If I use .playAndRecord, the audio I send out plays out on the radio. But, the now-playing deck is empty and nothing I do with the command center seems to change that. If I instead use .playback, I cannot use .defaultToSpeaker option which is the only way I've found to cause the "now-playing" navigation button to appear so that the full featured deck will display. But, of course setCategory() fails with an error about .defaultToSpeaker only available with .playAndRecord, so some default or intermediate state is entered and I see the full featured deck, but no audio goes out to the radio. What combination is supposed to be used here and is this more likely a problem with thread use (@MainActor) and/or some ordering of operations that I've overlooked?

I'm unclear on the implications of Apple's App Review Guideline 5.2.2: If your app uses, accesses, monetizes access to, or displays content from a third-party service, ensure that you are specifically permitted to do so under the service’s terms of use. Authorization must be provided upon request. If a paid subscription app uses a licensed search API to retrieve and display links to publicly available third-party web content, is the API license generally enough for compliance? Or does Apple expect separate authorization from each underlying website whose content appears in the search results?
