Confused about expiring certificates
Hi all, I got the email saying my certificate(s) will be expiring in 30 days. I can view my certificates (distribution, distribution managed, and 2x developments) on my account page. The distribution expires in 30 days (4/20/2023) The distribution managed expires in 6 months Development #1 (under my name) expires in 30 days (4/20/2023) Development #2 (also under my name) expires in 2 months (5/26/2023) However, I don't see any way to renew them. I have read other posts that talk about 'edit' or 'generate' buttons, but I don't see that and I presume those posts are just out of date. When I look in my xcode project, I see that I am using 'automatically manage singing'. Xcode also shows that a provisioning profile is expiring in 2 months. I presume that is something different? It has the same expiration date as my development #2 certificate (5/26/2023). It's also unclear what is going to happen when these certificates expire. I read that devices running builds with the expired distribution cert will stop working. Is that just for internal builds downloaded from something like Test Flight? Will live builds, downloaded by actual players from the AppStore, stop working if I don't push a release with a new cert in the next month? I am the one that set this all up and 'maintains' it, but I don't engage with it often enough to remember the bits and bobs. My apologies for all the newbie questions. Thank you for your assistance

Video not working on 16.4 simulator
I'm testing a video stream (HLS) with AVPlayer. On XCode 14.3 and simulators running iOS 16.4, there is no video image, only black screen. The audio is playing normally, also progress/duration of the video is showing as expected. The problem does not occur on same XCode version with earlier versions of the simulator. Is this a simulator bug? I've also tested it on real device with iOS 16.4 - no problem there.

Info.plist Heeeeeellllp
hello. i have 3 time started a new project now I am making a app and i get a Error code on Info.plist file. I have been trying to resolve an issue with the Info.plist file in an Xcode project. The error message is "Multiple commands produce" related to the Info.plist file. I have tried several approaches to fix the issue, including: Checking the "Copy Bundle Resources" section in the "Build Phases" tab of the project settings to ensure there is only one Info.plist file listed. Deleting the Info.plist file from the project and creating a new one, then updating the reference to the Info.plist file in the "Build Settings" tab. Can anyone help me with this??

Xcode cloud errors
Hi community: I'm coming across two error types on Xcode cloud during ui tests. encountered an error (Early unexpected exit, operation never finished bootstrapping - no restart will be attempted. (Underlying Error: Test crashed with signal kill before starting test execution. If you believe this error represents a bug, please attach the result bundle at /Volumes/workspace/resultbundlexcresult)) encountered an error (Failed to prepare device 'Clone 7 of iPhone 14 Pro' for impending launch. If you believe this error represents a bug, please attach the result bundle at /Volumes/workspace/ resultbundle.xcresult. (Underlying Error: Unable to boot the Simulator. launch failed to respond. (Underlying Error: Failed to start launch_ sim: could not bind to session, launchd_sim may have crashed or quit responding))) Any ideas on how to solve them? Thanks

Xcode 14.3: Restarting after unexpected exit, crash, or test timeout - How to debug?
My tests fail with "Restarting after unexpected exit, crash, or test timeout". This is what I have so far established: Does only happen when building with xcodebuild (14.3) but not when building with Xcode (14.3) Tests that are failing are in a .testTarget within a local swift package and part of a test plan together with tests that are in subprojects there are no crashlogs, so likely these tests are not crashing with Xcode 14.2 there are no problems whatsoever (xcodebuild or Xcode) Any ideas on how to debug this any further? Best Roddi

Error message "Thread 10: EXC_BREAKPOINT (code=1, subcode=0x10515fd44)" in Xcode
I have been getting these error messages in debug window in Xcode: 2023-06-06 07:46:15.412684-0500 Courier[8456:442818] [LayoutConstraints] Unsupported layout off the main thread for _UIModernBarButton with nearest ancestor view controller, UINavigationController 2023-06-06 07:46:15.413268-0500 Courier[8456:442818] [Assert] -[UIImageView _invalidateImageLayouts] must be called on the main queue 2023-06-06 07:46:15.413730-0500 Courier[8456:442818] [Assert] -[UIImageView _layoutForImage:inSize:cachePerSize:forBaselineOffset:] must be called on the main queue (lldb) The messages come when my code crashes and gives this error message in a red ribbon in the editor window: Thread 10: EXC_BREAKPOINT (code=1, subcode=0x10515fd44) In the Debug navigator on the left pane of Xcode, it shows the code stopped at: #0 0x000000010515fd44 in _dispatch_assert_queue_fail () This is what shows at the end in the editor window. At the very end is where the error message in the red ribbon shows: 0x10515fd10 <+68>: add x9, x9, #0xf2f ; "BUG IN CLIENT OF LIBDISPATCH: Assertion failed: " 0x10515fd14 <+72>: stp x9, x8, [sp] 0x10515fd18 <+76>: adrp x1, 65 0x10515fd1c <+80>: add x1, x1, #0xefa ; "%sBlock was %sexpected to execute on queue [%s (%p)]" 0x10515fd20 <+84>: sub x0, x29, #0x18 0x10515fd24 <+88>: bl 0x10519cfc8 ; symbol stub for: asprintf 0x10515fd28 <+92>: ldur x19, [x29, #-0x18] 0x10515fd2c <+96>: str x19, [sp] 0x10515fd30 <+100>: adrp x0, 65 0x10515fd34 <+104>: add x0, x0, #0xf65 ; "%s" 0x10515fd38 <+108>: bl 0x1051986b0 ; _dispatch_log 0x10515fd3c <+112>: adrp x8, 98 0x10515fd40 <+116>: str x19, [x8, #0x268] -> 0x10515fd44 <+120>: brk #0x1 I have no idea which code is causing the error, so I don't even know what code to put in my question. I created a symbolic breakpoint with 'LayoutConstraints' in the Symbol field. It is never tripped. I get no purple warnings that says a line of code should not be in the main thread. I have no idea where to go from here. I don't ind anything when I do a search in the internet that is narrowed down to address my error. I am running the code on an iPhone 13 Pro Max device with iOS 16.5. I am using Xcode 14.3 on a Mac Pro running Ventura 13.4

Use of 64pt and 68pt iOS App Icon Sizes
Hi there! Back with Xcode 14 and iOS 16 there were two new app icon sizes introduced to iOS: 64pt @2x (128x128px) 64pt @3x (192x192px) 68pt @2x (136x136px) What are those icons used for? Neither the Xcode 14 release notes nor the Human Interface Guidelines are mentioning those sizes and what they are used for. In previous Xcode versions the asset catalog had labels for each icon size. As Xcode 15 still doesn’t bring that feature back I’m still puzzled when those icon sizes are visible to the user. Best! – Alex

Upgrading to iPadOS 17 running RoomPlan gets exception on call to Rendering.

Using @Namespace in #Preview Xcode 15 gives an error message
Greetings... I am trying to use @Namespace for my matchedGeometryEffect use case. prior to Xcode 15 beta the following code worked just fine: struct ChapterItem_Previews: PreviewProvider { @Namespace static var namespace static var previews: some View { ChapterItem(namespace: namespace, show: .constant(true)) } } However trying to do the same within the new Xcode 15 beta #Preview Macro #Preview { @Namespace var namespace ChapterItem(namespace: namespace, show: .constant(true)) } produces the following error message: Ambiguous use of 'Preview(_:traits:body:)' May I kindly get assistance on the proper way I can get this to work in Xcode 15 beta? Please be as detail as you can since I'm still new to swiftUI as well Thank You.

Are Swift Packages supported by String Catalogs?
Hello, do the String Catalogs (new in Xcode 15) support Swift Packages? I've tried adding a new Localizable.xcstrings (string catalog) file to my package's resources folder. Great! I then see this screen: All good so far. I then try to go and build my Swift Package... and nothing changes. The string catalog is never populated and I'm left with the same screen as above. So, do string catalogs not support packages at this time or am I doing something wrong? I was really hoping String Catalogs would work and save the day since Export Localizations also does not work for Swift packages that don't support macOS. 😔

Why doesn't the Apple Vision Pro simulator appear as a run destination?
Throughout the WWDC guides and videos, Apple claims existing iOS and iPadOS apps will run in the visionOS Pro Simulator "unmodified." But none of my existing UIKit apps do. xrOS is installed and it does run for new project templates. But even after making sure "Apple Vision (Designed for iPad)" is added to my project settings, the destination never appears in the picker UI. What is Xcode detecting? If existing apps must be using SwiftUI or somesuch, then Apple needs to state that as a requirement. And if that is the case, is there a migration example of meeting this requirement without breaking or rewriting my apps?
