Overview

I am developing a standard UAC 2.0 device and encountered an issue where the channel names do not update according to the iChannelNames field in the Class Specific AS Interface Descriptor when switching between different channel counts. For example: AS1 (6 channels) is configured with the following channel names: ADAT 1, ADAT 2, ADAT 3, ADAT 4, HP L, HP R AS2 (4 channels) is configured with: ADAT 1, ADAT 2, HP L, HP R However, when switching from AS1 (6 channels) to AS2 (4 channels), the channel names displayed in Audio MIDI Setup do not reflect the change as expected. The actual result is: ADAT 1, ADAT 2, ADAT 3, ADAT 4 The system simply hides the last two channels; the names of the remaining channels are not updated. Initial Topology My original topology was as follows: Later, I discovered that macOS uses the iChannelNames field from the Input Terminal to display channel names. Therefore, I modified the USB device descriptors and updated the topology to the following: To distinguish the channel names for different channel counts, each Input Terminal is assigned a unique iChannelNames value. This method worked perfectly on macOS 15. However, after updating to macOS 26, this topology no longer displays the correct channel names. Question On macOS 26, what is the correct method to ensure that the channel names update dynamically when switching between different audio channel configurations?

I am using the native SwiftUI WebView and WebPage APIs (iOS 26+) and would like to implement file download functionality using the native SwiftUI WebView. However, I have not been able to find any APIs equivalent to WKDownload. In WKWebView, the WKDownload API can be used to handle downloads. I am looking for a similar API or recommended approach in the native SwiftUI WebView that would allow downloading files. If anyone has guidance or suggestions on how to implement this, I would appreciate your help.

I’m creating a new post because the situation has gone far beyond reasonable. My Apple Developer Program enrollment has been stuck in “Pending” status for almost a month. During this time, I have sent around 10 emails to Apple Developer Program Support. Result: ZERO REPLISES. NO EXPLANATIONS NO UPDATES. NO HELP. If you are experiencing the same issue — or have faced it before — please leave a comment or upvote this thread so it gets visibility. At this point, this seems to be the only way to get Apple’s attention. Apple, this situation needs to be addressed.

App is repeatedly rejected under Guideline 2.5.1 for referencing the private API:_SecCertificateIsValid Reported custom framework CommonLibrary.framework. The SDK is written in Objective-C and uses only public Security APIs. It does not use any deprecated APIs. We have verified the framework binary using nm, otool, and strings, and _SecCertificateIsValid does not appear in exported or hidden symbols. Bitcode is disabled, dead-code stripping is enabled, and the Release build uses -Os. Despite this, App Store Connect continues to detect _SecCertificateIsValid. We have attached herewith screenshots of our analysis for the reference. Can Apple’s server-side analysis or Security.framework internals still surface _SecCertificateIsValid? Is there a recommended way for SDK authors to prevent this symbol from being flagged?

Hi everyone, With the rapid growth of digital banking, payments, and AI-driven financial services, building secure and scalable FinTech apps on iOS has become more complex than ever. From handling sensitive user data to ensuring compliance and seamless performance, iOS developers face multiple technical challenges. Key areas that usually require deep expertise include: Apple Pay and Wallet integrations Secure authentication (Face ID / Touch ID / biometrics) Real-time transaction processing Core ML for financial predictions SwiftUI dashboards for financial analytics Data encryption and regulatory compliance https://www.nimbleappgenie.com At Nimble AppGenie, we’ve worked extensively as a FinTech app development expert, helping startups and enterprises design and build iOS financial applications that are secure, scalable, and user-centric. Our experience shows that the most successful fintech apps are those that balance strong security architecture with intuitive UX and performance optimization. I’m interested to hear from the community: What are the biggest challenges you’ve faced while building fintech apps on iOS? Are there any recent iOS updates or Apple frameworks that significantly improved your fintech workflows? How are you handling compliance and security in production apps? Looking forward to learning from everyone’s experiences and best practices.

Hi all - i'm encountering a strange issue since updating to Xcode 26.0.1. It seems that any SwiftUI Views that have an :ObservedObject property that contains @Published properties, and use those properties inside the View, no longer update when those properties are updated when the view also has an @Environment property. If I remove the @Environment property and any usage of it, the view updates correctly. The specific environment property i'm using is .safeAreaInsets, like so: @Environment(\.safeAreaInsets) private var safeAreaInsets Is this a recognised bug in the latest iOS 26 SDK? Thanks

My iphone glitched and turned off and would not turn back on. I have already tried force restart by charging it and everything but it stays as a black screen even though my phone vibrates and everything.

Hi. I'm trying to show 3D or AR content in multiple pages on an iOS app but I have found that if a RealityView is used earlier in a flow then future uses will never display the camera feed, even if those earlier uses do not use any spatial tracking. For example, in the following simplified view, the second page realityView will not display the camera feed even though the first view does not use it not start a tracking session. struct ContentView: View { var body: some View { NavigationStack { VStack { RealityView { content in content.camera = .virtual // showing model skipped for brevity } NavigationLink("Second Page") { RealityView { content in content.camera = .spatialTracking } } } } } } What is the way around this so that 3D content can be displayed in multiple places in the app without preventing AR content from working? I have also found the same problem when wrapping an ARView for use in SwiftUI.

I've connected my Claude account into Coding Intelligence and working properly (opening a web browsing and connecting my account), but when I press Claude Agent it sayes that I have to login againt. When I press the Account login with Claude.ai account, a web browser is opened, but it never finished the flow and I have an infinite spinner. Apple M2 Pro with macOS 26.2 (25C56)

Hey everyone, I purchased an Apple Developer Program for 99 USD on January 1 2024, filled out my credit card that I use for iCloud+ storage plan, got my confirmation email that within 48h my developer account should be activated, but it never did. Plus after waiting more than 48h I wrote to support, describing everything, but never heard back from them. One thing I noticed during the checkout was I was asked for everything (name, address, CC number, expiry date) but not the CVV number. Is this normal, and would Apple be able to process the payment without it? I though about going through the enrolment process again, but am afraid of a double charge, in case my original enrolment gets accepted... Please advise and share your experiences when enrolling to the developer program. Thanks!

Since last year, our company has been signing in new users to Apple Store Connect using our private email domain. However, since last week, when we try to sign in with this same domain, we receive the following error: "Your primary email address cannot end in @mydomain.com.br. Choose a different email address."

My app is already in production, and there are purchases. But people from Europe cannot download it because I need to pass DSA compliance. The DSA regulation status has been “in review” for about a month already. What do I need to do?

I'm trying to enroll in Apple Developer and I continuously getting a "Payment Declined" message despite trying 4 credit cards, a debit card and even my apple card. When I try this through the developer app the "Enroll Now" button is greyed out. It's not a bank issue I've already checked and they don't see any requests coming through. I’ve tried multiple times with no luck. Contacted Apple support and they are extremely slow with the responses with very little help. Does anyone have any thoughts on how to fix this?

Based on https://developer.apple.com/documentation/networkextension/nednssettings/searchdomains , we expect the values mentioned in searchDomains to be appended to a single label DNS query. However, we are not seeing this behavior. We have a packetTunnelProvider VPN, where we set searchDomains to a dns suffix (for ex: test.com) and we set matchDomains to applications and suffix (for ex: abc.com and test.com) . When a user tries to access https://myapp , we expect to see a DNS query packet for myapp.test.com . However, this is not happening when matchDomainsNoSearch is set to true. https://developer.apple.com/documentation/networkextension/nednssettings/matchdomainsnosearch When matchDomainsNoSearch is set to false, we see dns queries for myapp.test.com and myapp.abc.com. What is the expected behavior of searchDomains?

When using an image in a List item, you sometimes want to tint that image, but only if the item isn’t selected. When it’s selected, you usually want the contents of the list item to be all-white, for contrast. The backgroundProminence Environment value ostensibly exists for this purpose, but in my tests, it never seems to change. Am I doing something wrong? Is there an alternative solution? For instance, this code: import SwiftUI struct ProminentBackgroundInList: View { var body: some View { List(selection: .constant(0)) { ListItem().tag(0) ListItem().tag(1) } } } struct ListItem: View { @Environment(\.backgroundProminence) var backgroundProminence var body: some View { HStack { Image(systemName: "person.fill") .foregroundStyle(backgroundProminence == .standard ? .orange : .primary) Text("Person") } } } #Preview { ProminentBackgroundInList() } Produces this result:

Hello, I'm implementing the wallet extension for a financial app. Right now I'm having a problem, I want to redirect to the main app when the user hasn't logged in. Is it possible? This is my code in the WalletUI. It just doesn't work. let urlString = "bank://login" guard let url = URL(string: urlString) else { return } self.extensionContext?.open(url, completionHandler: { success in if !success { print("Success") } else { self.completionHandler?(.canceled) } }) }

I’m having an issue verifying a domain for a Merchant ID. I’m implementing Apple Pay on the web for a demo, and I’ve configured the Azure server to match Apple’s requirements for domain verification, such as the TLS configuration, not requiring client certificates, and ensuring there are no redirects. I’ve run tests with OpenSSL and PowerShell and all responses return HTTP/1.1 200 OK. I also tested the URL Apple says it uses to validate the file under .well-known, and it does show the expected result. I already have the Apple Pay Payment Processing Certificate and the Apple Pay Merchant Identity Certificate approved; the only thing missing is the domain verification. I’m not sure what else to test—if you could help me with a possible solution, I’d really appreciate it. (The project is built in .NET 8 and hosted on Azure App Service.)

I'm trying to display CPButtons (CPContactCallButton, CPContactMessageButton) in CPContactTemplate. They are displayed using device with iOS16, but with iOS26 device CPContactTemplate only displays contact image and contact name. No buttons. Is it a bug? I don't have iOS17/18 devices to try.

Hello, We're developing endpoint security software using the Endpoint Security framework, and we've encountered challenges with the behavior change in macOS 15 regarding provisioning UDIDs in cloned VMs. The Change Prior to macOS 15, cloning a VM preserved its UDID (format: 0000FE00-9C4ED9F68BBDC72D). Starting with macOS 15, cloned VMs receive a new UDID generated from the host's Secure Enclave (format: b043d27202c7ac37ca3c6b82673302225485cae9), making each clone effectively a new device. Our Workflow We maintain a clean base VM image and clone it for each test run. We add the base VM's UDID to our provisioning profile once, then create clones which (previously) retained that same UDID, allowing us to start new testing cycles without re-registering devices. This is essential because our product involves low-level system integration through the Endpoint Security framework, and if something goes wrong during development, it has the potential to affect system stability. To prevent any cascading issues between test runs or different product versions, we need each test to start from a known clean state rather than reusing the same VM. The Challenge With each VM clone generating a new UDID, we're hitting Apple's device registration limits quickly. This particularly impacts: New team members who spin up VMs for the first time and can't run signed builds Our CI/CD pipeline where multiple test environments need provisioning profiles Developers testing different branches who need separate clean environments Current Workaround We've found that VMs created on macOS 14 and upgraded to macOS 15+ retain their original UDID format. However, we're concerned this workaround may stop working in future macOS versions, which would leave us without a viable path forward. If the workaround stops working, our fallback would be signing each CI build with a Developer ID signature to allow running on any device. However, we'd prefer to avoid this as it would significantly increase load on Apple's signing infrastructure for what are essentially internal test builds. We completely understand the security reasoning behind tying UDIDs to the host's Secure Enclave for Apple Account support. However, for development workflows that don't require Apple Account features in VMs but do require clean, isolated test environments, the previous behavior was quite valuable. Question Is there a recommended approach for teams in our situation? We're happy to explore alternative workflows if there's a pattern we're missing, or we'd be glad to provide more context if this is a use case Apple is considering for future updates. Thanks for any guidance you can provide! Feedback case: FB21389730
