Beginner’s question on learning philosophy.
Hello Everyone! I started programming 6 months ago and started Swift / IOS last month. My learning so far has mainly been with Python. I learned a lot of the package ‘SQLAlchemy’, which has very ‘example based’ documentation. If I wanted to learn how to make a many to many relationship, there was a demonstration with code. But going into Swift and Apple packages, I notice most of the documentation is definitions of structures, modifiers, functions, etc. I wanted to make the equivalent of python ‘date times’ in my swift app. I found the section in the documentation “Foundation->Dates & Times”, but I couldn’t figure how to use that in my code. I assume my goal should not be to memorize every Swift and apple functionality by memory to be an app developer. So I would appreciate advice on how to approach this aspect of learning programming.

Reply to RealityKit and USDZ: Winding Order Issue with Negatively Scaled Meshes
Thanks for following up, and apologies for the delay-- this slipped past me. Here’s a repro asset I wrote that you can test directly: https://github.com/alexchuber/Assets/raw/refs/heads/main/Repros/triangleNegScale.usdz For additional reference, here's the USDA content of the asset (material omitted for clarity): #usda 1.0 ( defaultPrim = Root metersPerUnit = 1 upAxis = Y ) def Xform Root { def Mesh Triangle { matrix4d xformOp:transform = ( (-1, 0, 0, 0), (0, 1, 0, 0), (0, 0, 1, 0), (0, 0, 0, 1) ) uniform token[] xformOpOrder = [xformOp:transform] int[] faceVertexCounts = [3] int[] faceVertexIndices = [0, 1, 2] normal3f[] normals = [(0, 0, 1), (0, 0, 1), (0, 0, 1)] ( interpolation = vertex ) point3f[] points = [(0, 0, 0), (1, 0, 0), (0, 1, 0)] uniform token subdivisionScheme = none } } The steps to reproduce are just: Add the asset to a new Reality Composer Pro scene. Open the same asset in QuickLook on iOS/macOS. Compare the facing direction in both views. You should see that the triangles appear to have opp

Weird crash: missing symbol Swift.AsyncIteratorProtocol.next()
I got several reports about our TestFlight app crashing unconditionally on 2 devices (iOS 18.1 and iOS 18.3.1) on app start with the following reason: Termination Reason: DYLD 4 Symbol missing Symbol not found: _$sScIsE4next7ElementQzSgyYa7FailureQzYKF (terminated at launch; ignore backtrace) The symbol in question demangles to (extension in Swift):Swift.AsyncIteratorProtocol.next() async throws(A.Failure) -> A.Element? Our deploy target is iOS 18.0, this symbol was introduced in Swift 6.0, we're using latest Xcode 16 now - everything should be working, but for some reason aren't. Since this symbol is quite rarely used directly, I was able to pinpoint the exact place in code related to it. Few days ago I added the following code to our app library (details omitted): public struct AsyncRecoveringStream: AsyncSequence { ... public struct AsyncIterator: AsyncIteratorProtocol { ... public mutating func next(isolation actor: isolated (any Actor)? = #isolation) async throws(Failure) -> Element? { ...

Reply to Building macOS apps with Xcode 26 on macOS 26 VM
Yeah! It's working! I have a macOS 26.0 host. In UTM I have a macOS 15.7 guest with a Provisioning UUID that has never been added as a device in the developer portal. In my developer account I added a new device with the guest VM's UUID. It's the longer style with lowercase hex digits. I then edited my existing manual provisioning profile with the new device. In Xcode (26.1 beta 2) I changed my app's signing from automatic to manual and referenced the updated provisioning profile. I built the app and copied the new app to a share I use for the VM. I ran the VM and tried to run the updated app. It failed. I missed one step that maybe some others might miss. In Xcode, go to Settings, Apple Accounts. Select your account. Then select your team. Then click on Download Manual Profiles. Once I did that, I rebuilt the app with the now properly updated provisioning profile and recopied the app to the share. And now the app runs in the guest VM! Key steps for those that are not starting from scratch:

Use CCID interface instead of CryptoTokenKit API
Hi, Is it possible for a macOS (or iOS/ipadOS) app to communicate with a CCID-compliant reader using the CCID interface (i.e., directly sending the PC_TO_RDR_* messages) instead of using the CryptoTokenKit API? Apple's CCID driver (/System/Library/CryptoTokenKit/usbsmartcardreaderd.slotd) seems to support all the PC_TO_RDR and RDR_TO_PC messages: https://blog.apdu.fr/posts/2023/11/apple-own-ccid-driver-in-sonoma/#enable-my-ccid-driver The background for this question is that we develop smartcard products and we'd like to use the finer grained settings provided by the CCID specification for testing/demo purposes. Thank you.

Reply to PCIDriverKit entitlements during development
I was asked to follow up on FB19449747 after this was supposedly fixed, so I did. I can't see a DriverKit PCI Transport (development) entitlement in the list of available Capabilities. Huh. Can you double-check on the portal just to be sure? I've checked on three different teams I have access to, and all of them are showing it. A few things to note: It's actually called DriverKit PCI (development), simply to keep the name length a bit more manageable. I just noticed that it doesn't currently include the extra Development only. Learn more Provisioning support required. label on the portal (I'm working on fixing that). I also noticed that it's offering iOS as a platform, which turned out to be one example of a much broader bug (r.162380702). It turns out that several DriverKit entitlements also include extra platforms, which means they can be included in targets they should not be included with. I don't think including them will actually cause any problems (macOS will just ignore them), but it's definitely some

DriverKit. Plug/unplug test leads to MacOS panic
Dear Apple engineers, We have developed a DriverKit (DEXT) driver for an HBA RAID controller. The RAID controller is connected to hosts through Thunderbolt (PCIe port of the Thunderbolt controller). We do plug/unplug tests to verify the developed driver. The test always fails in about 100 cycles with a MacOS crash (panic). The panic contains “LLC Bus error (Unavailable) from cpu0: FAR=0xa40100008 LLC_ERR_STS/ADR/INF=0x80/0x300480a40100008/0x1400000005 addr=0xa40100008 cmd=0x18(ACC_CIFL2C_CMD_RD_LD: request for load miss in E or S state)” At first we assumed that the issue is with hardware. But we did this test on different hosts (MacMini M3 and M4) with different units of our device. The error points to the same physical address FAR=0xa40100008 even if the hosts are different. The 2 full panic logs are attached (one for M4, another one for M3 host). Could you share your understanding of the crash and give any hints on how we can fix it? Please let us know if you need any additional data. Thank you M3

Sign In with Apple Integration Issue - "Sign-Up not completed" Error
I'm experiencing an issue with Sign In with Apple integration in my React Native Expo app (Bundle ID: com.anonymous.TuZjemyApp). Problem Description: When users attempt to sign in using Sign In with Apple, they successfully complete Face ID/password authentication, but then receive a Sign-Up not completed error message. The authentication flow appears to stop at this point and doesn't return the identity token to my app. Technical Details: Frontend Implementation: Using expo-apple-authentication. Requesting scopes: FULL_NAME and EMAIL App is properly configured in app.json with: usesAppleSignIn: true Entitlement: com.apple.developer.applesignin Backend Implementation: Endpoint: POST /api/auth/apple Using apple-signin-auth package for token verification Verifying tokens with audience: com.anonymous.TuZjemyApp Backend creates/updates user accounts based on Apple ID Question: I'm not sure why the authentication flow stops with Sign-Up not completed after successful Face ID verification.

Macos Tahoe issue launching apps through SSH
On a CI infrastructure we connect nodes through SSH, and launch automated apps testing. Since Macos Tahoe: When launching an App through SSH with full executable binary path App doesn't show up in apps bar and top menu No keyboard events are received (mouse work well) How to reproduce: ssh /Applications/Pages.app/Contents/MacOS/Pages # ==> Navigate until you can enter text, no keyboard input are working # ==> App do not show up on app bar # ==> Work as expected if launched from a local terminal open /Applications/Pages.app # ==> work well Do I miss a system configuration to restore ability to launch apps from SSH ? Note: We use full executable binary path (not bundle path/.app folder) because our test application require this full path (Qt Squish)

Transfer of an App with Sign in with Apple Functionality
Hello, I currently have an app that includes the Sign in with Apple feature, and I need to transfer this app to another app team. I have reviewed all official documentation but have not found the answer I need. My situation has some specificities, and I hope to receive assistance. The .p8 key created by the original developer team has been lost, and the app’s backend does not use a .p8 key for verification—instead, it verifies by obtaining Apple’s public key. However, according to the official documentation I reviewed, obtaining a transfer identifier during the app transfer process requires a client_secret generated from the original team’s .p8 key. This has left us facing a challenge, and we have two potential approaches to address this issue: Q1: During the transfer, is it possible to skip obtaining the transfer identifier and proceed directly with the app transfer, without performing any backend operations? Is this approach feasible? Q2: If the above approach is not feasible, should we create a ne

Unable To Perform Stapler Process
I am facing an issue while trying to staple a notarization ticket to my signed macOS installer package. Details of my setup: The .pkg file is signed using my Developer ID Installer certificate. The app inside the package is signed using my Developer ID Application certificate. Notarization via xcrun notarytool completes successfully with status: Accepted. However, the stapler command fails with the following error: xcrun stapler staple -v /Users/mac-test/Desktop/IPMPlus_Arm_Installer_signed.pkg Processing: /Users/mac-test/Desktop/IPMPlus_Arm_Installer_signed.pkg Could not validate ticket for /Users/mac-test/Desktop/IPMPlus_Arm_Installer_signed.pkg The staple and validate action failed! Error 65. I verified that all other Apple notarization-related servers (api.apple-cloudkit.com, gs.apple.com, ocsp.apple.com, ocsp2.apple.com, crl.apple.com, developer.apple.com) are reachable.

X missing dependency on Y because dependency scan of Swift module 'X' discovered a dependency of Y
In my app target Foo, I have a dependency on package Bar. Bar itself have a dependency on another package Other. In my test target FooTests, I have a dependency on package BarTestsHelpers. BarTestsHelpers depends on Bar. When compiling test target FooTests, I get the following unexpected warning in Xcode 26 only: 'Bar' is missing a dependency on 'Other' because dependency scan of Swift module 'Bar' discovered a dependency on 'Other' I can see this is being discussed here as well without a solution. I filled a feedback with a sample project here: FB20602885 It seems that we can remove the warning by explicitly adding the dependency Other on BarTestHelpers. But this shouldn't be needed as BarTestHelpers doesn't use nor know about Other, it only needs it as part of its dependency on Bar.
