Overview

I'm building a custom camera screen that displays the camera image on a preview layer and then captures an image, using AVCaptureSession. When the picture is captured, I immediately load it into a UIImageView in order to display it to the user for approval. I've actually done this many times before, but this is the first time I've tried to do it in an app that supports interface rotation. If I hold the phone in Portrait mode and capture a picture, everything works as expected. When the user rotates the phone into Landscape orientation, I detect this and I replace the preview layer (AVCaptureVideoPreviewLayer) with a new one, specifying connection.videoRotationAngle in order to make the image appear in the right orientation. I'm a little surprised that this is necessary, and it's not a smooth transition, but that doesn't matter. What does matter is that when I capture the image, it is in the wrong orientation. I tried rotating it myself, but this doesn't seem to make any difference. What am I doing wrong?

I am running Xcode 16.1, macOS 15.1 , iOS 18.1, and I see the error when trying to run the Instruments Network Profile

Description As of iOS 18, AVAudioSession.setPreferredIOBufferDuration ignores the requested buffer size when Sound Recognition or Vocal Shortcuts is enabled. This results in 1) much larger buffer sizes and 2) mismatched buffer sizes between input and output buffers, which causes ‘glitchy’ audio and increased latency. Additionally, when this issue occurs AVAudioSession.setPreferredIOBufferDuration continues to return ‘true’ and no error is produced. Steps to Reproduce: Enable Vocal Shortcuts on a device running iOS 18. Enable at least one shortcut (e.g. Control Center). Open or clone the example project (https://github.com/cwalo/SoundRecognitionBug) Build and install the example project Attach a headset and launch the application Observe console logs showing a requested buffer size of 0.005805 (256 samples @ 48k) an actual buffer size of 0.023220 (1104 samples @48k - this is regularly the resulting buffer size in all of our tests) Quit the app and detach the headset. Enable mutesOutput in AudioSystem.mm (to avoid feedback) Launch the application Observe Same result from step 4 Mismatched hardware buffer size of 1104 and recorded frame count of 1024 Mismatched playbackCount and recordCount Quit the app and disable vocal shortcuts Launch the app Observe IOBufferDuration matching the requested duration and matched buffer sizes (expected behavior) Expected results: Requested IOBufferDuration is respected or AVAudioSession returns false or error is produced Input and output buffer sizes match Device(s): iPhone 11 Pro, iPad Pro OS: iOS 18.0.1 Environment: Xcode 16.1 FB: FB15715421 Related to: https://forums.developer.apple.com/forums/thread/765477

For an upcoming update of one of my apps, I’m facing an issue: The .rate parameter of a AVAudioUnitTimePitch allows me to slow down an audio track without any issues: setting .rate to 0.7 or 0.8 results in an almost perfect playback without changing pitch. However, whenever the .rate parameter is greater than 1 (e.g. 1.1 or 1.15), I’m starting to hear audio artifacts (“flattering”) in the audio output which is not so nice (even at .overlap = 32). Intuitively, I’d’ve thought that speeding up the file should contain less artifacts than slowing it down?? I’ve tried different sample rates (44.1 kHz and 48 kHz), but same result. Grateful for any input on this 🙏

Hi, wanted to test if possible to use Mesa3D Dozen driver(Vulkan on D3D12 )+D3DMetal 2b3 to get maybe better Vulkan driver on Wine than default MoltenVK.. this will support Vulkan windows apps via using D3D12Metal.. using vulkan_dzn.dll,dzn_icd.x86_64.json,dxil.dll from x64 folder from: https://github.com/pal1000/mesa-dist-win/releases/download/24.3.0-rc1/mesa3d-24.3.0-rc1-release-msvc.7z using simple vulkaninfo app and running like: wine64 vulkaninfo I get error: [D3DMetal:LOG:2A825] Unsupported API: CheckFeatureSupport, unhandled support query 53 also seems D3DMetal Wine integration on Whisky doesn't expose d3d12core.dll and d3d12.dll like new Agility D3D12 dlls or VKD3D, so getting: MESA: error: Failed to retrieve D3D12GetInterface MESA: error: Failed to load DXCore but anyways seems to try to load the driver as: WARNING: dzn is not a conformant Vulkan implementation, testing use only. full log: MESA: error: Failed to retrieve D3D12GetInterface MESA: error: Failed to load DXCore WARNING: dzn is not a conformant Vulkan implementation, testing use only.

Hi all, Our app allows a user to scan a room and then save that scan on a separate view, followed by additional scans. We're looking into allowing room combining via CapturedStructure, so we need rooms to be scanned in the same ARWorldMap without necessarily needing to re-localize in the same session. This should fit within the first scenario that Apple described. The only way I have found that allows our requirements is to save RoomCaptureView and to re-use that RoomCaptureView whenever we need to start a session again. This creates a number of other issues, and ideally, we wouldn't need to save a View in something like a singleton. We are using captureSession.stop(pauseARSession: false). Additionally, if we use the same RoomCaptureView and an error occurs during the scanning process, we can't get the instructions overlay to appear again if we reuse this view (specifically, the instructions in the middle of the view that state "Move device to start"). It's as if the instructions are completely removed and scanning is stuck on an error state if an error occurs. These instructions also seem to be separate from the instructions we can grab from RoomCaptureViewDelegate via didProvide instruction: RoomCaptureSession.Instruction), so we can't use that either. There's a couple subviews that seem relevant to this: RoomCaptureCoachingOverlayView and ARGlyphView - but both are not public, so we can't force them to appear. Also attempted a number of other things to try to get these subviews to appear, such as layoutIfNeeded(). Saving the ARSession and using it in let roomCaptureView = RoomCaptureView(frame: viewBounds, arSession: arSession) where we're creating a new view with the same ARSession seems much more ideal as that solves the above issues, but we run into another issue: world tracking seems to be completely lost when a new RoomCaptureView (and thus a new RoomCaptureSession) is started, even with the same already started ARSession, almost as if captureSession.stop(pauseARSession: false) doesn't work as described. Is there any way around needing to use the same RoomCaptureView or RoomCaptureSession for subsequent scans in the same session without needing to re-localize via ARWorldMap loading? Is there a way to force the guiding instructions to appear?

iPhone 15pro iOS 18.2 Downloaded files cannot be located anywhere in Files, only by accessing Downloads in Safari. I have tried setting download folder to various locations, iCloud, Phone, Google Disk, but nothing is stored. Has an invisible cache or temp folder been introduced? If so, it is a total fail: When press-holding any file in Safari download, the normal file action options (Quick Look, share, store to Files, etc) are not available. When clicking any file it opens any of several apps that has this file type associated with it, and there is no way to change the default app or disable the forced opening of an app. I tried deleting the app opening .csv (in this case OneDrive), and another irrelevant app opened. There seems to be a hierarchy of apps-file types, and it has no logic to it. in Chrome behaviour is as expected. Chrome vs. Safari screen recordings: https://shorturl.at/my3Oy

I'm trying to develop an app to control HomeKit accessories in a way not available so far in macOS. How can I work around the absence of HomeKit Support for macOS in Xcode 16? Thanks!

Can someone give me an easy way to fix this code?

What is recommended best practice for importing a Blender 3D file into RCP? I assume as a .usdz file? Is there a WWDC24 session or other Apple resource that best explains this. I want to make sure I provide the right format/file to RCP from Blender.

WWDC21 had a cool demo project with fish, with a watery, misty look (Dive into RealityKit). It used post processing in RealityKit, but the ARView class isn’t available in VisionOS. Can CompositorLayer be used instead for post processing in full immersion?

Hello, We are developing Apple pay with In-app provisioning, we are an agent of payment for a bank in France. We have already configured all the entitlements, and we think we have correctly configured things with our PNO It's a react native app and we are able to follow the flow that opens the native dialogue, show the card, then retrieve the Terms & Conditions but when we click accept we get the error: "Could not add card" we're experiencing exactly the same problem described in this other thread: https://forums.developer.apple.com/forums/thread/765832 In the logs we see the response: { errorCode = 40456; statusCode = 500; } Our PNO swears they have configured their system in the right way. They only have 3 fields that they have configured as follows: associated application identifier: {team_id}.{bundle_id} associated store identifier: {adam_id} application launch url: {app_name}:// Are these correct? Attaching the details of a request and response request.txt response.txt We reached out to the Apple Pay team who said we should talk to Technical support. Can somebody help us please? We are stuck at the moment and we really need to make this work. We can provide all the details of the syslog output if needed many thanks in advance! Thomas

I have a Safari extension which allows the user to load their own homepage upon opening a new tab. The extension works by retrieving the homepage URL from UserDefaults and then redirecting to it using window.location.replace. In iOS 18, if the homepage is unable to be loaded due to, for example the user having no internet connection, Safari will go into an rapid loading loop, which eventually stops after a while. This is unlike iOS 17, where trying to reproduce the same scenario will end up with a Safari error page, which should be the expected behaviour. In short, instead of Safari going into an infinite loading loop, it should display a Safari error page like iOS 17 does. As this issue is only happening on iOS 18, I am almost certain it's an iOS bug and would appreciate if this can be fixed as soon as possible. I have created a Feedback Assistant report with ID FB15853821, which contains a sysdiagnose file from my iPhone 16 Pro, as well as two videos, one from my iPhone 16 Pro with iOS 18.2 beta 3 and the other video showing a comparison between iOS 18 and 17. Both videos first show the extension functioning correctly with an active internet connection, but when I disable my internet, the iOS 18 Safari goes into an infinite loop. Here are the steps to reproduce the issue: Download the Homepage for Safari app from the App Store: https://apps.apple.com/gb/app/homepage-for-safari/id6481118559 Enter any valid homepage URL, such as https://apple.com and tap Save Go to Settings -> Apps -> Safari -> Extensions -> Homepage and enable the extension Make sure Open New Tabs is set to “Homepage” Turn off both WiFi and cellular data and attempt to open a new tab in Safari Please note that this also happens with iOS 18.2 beta 4.

If I have a Catalyst app with a WKWebView and I select text, I can drag forward to extend the selection, but I can't reduce the length of the selected range by dragging backwards. I've reproduced this in a trivial sample app. Is there some property I need to set somewhere? I've filed this as FB15645411.

Hello everyone. I would like to let everyone know that I am excited to get an Apple developer account. As soon as I stepped in, I faced the first problem. When I try to buy the Apple developer membership through the app, the person asks for an ID card. It automatically fills in the name and surname part. If we try to become a member via the web, the person does not ask for an ID card and we can enter the name and surname field as we wish. I am at the payment screen and I entered my website name in the name and surname field. Will Apple close my account? Will I be prevented from receiving money through the app? What do you recommend me to do? I don't want to use my own name

We submitted firewall request to below destination subnets and we still see connection refused to port 5223. Please advise why are we seeing connection refused and should we need 5223 port. Subnets - 17.249.0.0/16, 17.252.0.0/16, 17.57.144.0/22, 17.188.128.0/18, 17.188.20.0/23

Currently Apple has their own calendar called Birthdays which takes the birthdays from contacts and makes it as a regular calendar event along with the birthday number, they even do this for Hebrew Birthdays. I have tried (unsuccessfully thus far) to take the same concept and create a calendar for reoccurring events on a specific date in the Hebrew Calendar. An example of this would be Yahrtzeits, which is observed on the Hebrew date each year after a person dies. I want to add it to the system calendars like how Apple does it this way it can be used with any app not just my own. Currently there isn't a way to specify the calendar (like Calendar(identifier: .hebrew) or even make a custom EKRecurrenceRule, also from some of the debugging of the Birthdays calendar, it seems that the date saved is the Gregorian date and that theres some internal calculations happening. Is there a way to add reoccurring Hebrew Events or do I need to reinvent the wheel?

Hi there - I maintain the react-native-apple-authentication module which allows react native developers to implement sign in with Apple When testing we noticed that code working perfectly in iOS17 Simulators now fails on iOS18/18.1 Simulators. Specifically, the credential status is always revoked when testing on an iOS18+ Simulator. The same code works perfectly on a real device running iOS18 or 18.1 so this appears to be a Simulator bug. This is problematic because App review is frequently performed on a Simulator, so there are false-negative test results for Sign In With Apple from reviewers when they use iOS18 emulators, resulting in App submission rejections. We're tracking this here, with some results posted and an example app in-repo that demonstrates the issue: https://github.com/invertase/react-native-apple-authentication/issues/356 It would be great to see the Simulator fixed so that it works correctly with Sign In With Apple again. Thanks

To quickly change emails to “read” status in gmail, I tap on emails (opening them) and when in the email I either swipe right or tap the back arrow to return to inbox. I like to do many of these in quick succession to get rid of the amount of unread emails I have. Once an email is opened, it freezes on the opened page and I have to exit the Gmail app to unfreeze it. About every second or third email in a row is freezing
