I am able to capture 48mp photos using .builtInWideAngleCamera, but it seems like .builtInTripleCamera is capped at 12mp?
Is there a way to capture 48mp photos using .builtInTripleCamera? Because .builtInTripleCamera provides smooth transition between cameras during zooming, and I'd like to keep this behavior.
New iPhone 17 Pro have all their cameras at 48mp. Is there a chance that their .builtInTripleCamera is capable of capturing 48mp? Or is this an API limitation?

Error capturing ProRAW using iPhone 17 Pro Telephoto with photoQualityPrioritization set to .Quality
Hey,
I'm having a very strange issue on my iPhone 17 Pro. I'm trying to capture a 12MP ProRAW image using the Telephoto Lens with the photoQualityPrioritization set to .Quality. Unfortunately I receive this error when trying to capture the image:
Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSUnderlyingError=0x134f7a1f0 {Error Domain=NSOSStatusErrorDomain Code=-16802 "(null)"}, NSLocalizedFailureReason=An unknown error occurred (-16802), AVErrorRecordingFailureDomainKey=4, NSLocalizedDescription=The operation could not be completed}
The photo captures correctly at 7.9x zoom, it's only a problem when the zoom goes over 8x.
Also, it's only this particular configuration of settings which causes the issue. I'm able to capture an image if I either:
Set quality to ".balanced"
Set max dimensions to 48MP
Capture a JPEG image instead of a ProRAW image
Use the TripleCamera fusion lens
Any help would be greatly appreciated.

I want to fully support the new iPhone models in my app, and ideally need to know the available lenses. However, I can't find information about this on the web and they're not reported in the simulators. The closest thing I found was this, but it's very out of date. https://developer.apple.com/library/archive/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/Cameras/Cameras.html
My only other option is to buy each device, which isn't really feasible, or to log the data from real users via an analytics tool which isn't ideal either.
Thanks,
Alex

When attempting to access a PHAsset that is in the hidden folder of iOS26, the PHFetchResult always returns no items, even when the user has granted full access to photos and even when includeHiddenAssets is true.
This is the code suggested by ChatGPT; it always fails:
public func fetchAsset(withLocalIdentifier identifier: String) -> PSSPHAssetImplementing? {
// First try the direct fetch by identifier (fast path)
let directResult = PHAsset.fetchAssets(withLocalIdentifiers: [identifier], options: nil)
if let asset = directResult.firstObject {
return build(from: asset)
}
// Fallback: fetch all assets including hidden, then filter manually
let options = PHFetchOptions()
options.includeHiddenAssets = true
let allAssets = PHAsset.fetchAssets(with: options)
for index in 0..<allAssets.count {
let asset = allAssets.object(at: index)
if asset.localIdentifier == identifier {
return build(from: asset)
}
}
return nil
}
Is it no longer possible to retrieve a hidden photo in iOS 26?
Area
ImageCaptureCore / ICDeviceBrowser
Description
On iOS 26.1 beta, calling
requestControlAuthorization()
requestContentsAuthorization()
always returns .notDetermined and never transitions to .authorized or .denied.
This prevents apps from properly accessing device control or contents authorization. The issue occurs regardless of device state or prior requests.
Steps to Reproduce
1. Create and start an ICDeviceBrowser instance.
2. Call requestControlAuthorization() or requestContentsAuthorization().
3. Inspect the returned ICAuthorizationStatus.
Expected Result
• The system should prompt the user if necessary.
• A final status of either .authorized or .denied should be returned.
Actual Result
• The completion handler always reports .notDetermined.
• No user prompt appears and the status does not change.
Version / Build
• iOS 26.1 beta
• Xcode
Hardware
• [iPhone 15 Pro, iPad Pro (M2)]
Impact
This regression blocks development and testing of features relying on ImageCaptureCore. Applications depending on device browsing and content access cannot proceed, which significantly affects workflows involving external device integration.
Notes
This appears to be a regression compared to earlier iOS releases.
Hi, We have created an app which allows recording 4K 60 fps videos in the app. We have noted that some time the recording switched to 20 fps (the value 20 is constant) even though the resolution settings is at 4K 60fps. We are using AVCaptureDevice to invoke the camera.
has anyone experienced this problem before ? What is unique to 20 fps? Why does it resort to 20 fps from 60 fps and why not to other numbers ?

I discovered when editing photos with the PhotoKit API, PHContentEditingOutput's renderedContentURL is a file in the app container's tmp directory with a filename that seems to follow the format render.<uuid>.JPG, and that file does not get deleted if the edit does not complete successfully (the user cancels the edit request, an error occurs, the app crashes, etc). I understand the system is supposed to automatically delete tmp files every once in a while, but some users are noticing my app's Documents & Data inflates, so I'm considering deleting these render files each time the app is launched. But I don't want to delete everything in the tmp directory as there could possibly be other data in there.
What's the best way to remove those temporary files? Does the filename always start with render. no matter the device language? I thought I'd delete files in NSTemporaryDirectory() with that prefix but then I discovered in Mac Catalyst the location is not the tmp directory directly, they're in tmp/TemporaryItems/<bundleid>.
Thanks!
Just downloaded iOS 26.1 and my phone keeps ringing after the call has been answered. Any fixes for this?

My implementation of LockedCameraCapture does not launch my app when tapped from locked screen. But when the same widget is in the Control Center, it launches the app successfully.
Standard Xcode target template:
Lock_Screen_Capture.swift
@main
struct Lock_Screen_Capture: LockedCameraCaptureExtension {
var body: some LockedCameraCaptureExtensionScene {
LockedCameraCaptureUIScene { session in
Lock_Screen_CaptureViewFinder(session: session)
}
}
}
Lock_Screen_CaptureViewFinder.swift:
import SwiftUI
import UIKit
import UniformTypeIdentifiers
import LockedCameraCapture
struct Lock_Screen_CaptureViewFinder: UIViewControllerRepresentable {
let session: LockedCameraCaptureSession
var sourceType: UIImagePickerController.SourceType = .camera
init(session: LockedCameraCaptureSession) {
self.session = session
}
func makeUIViewController(context: Self.Context) -> UIImagePickerController {
let imagePicker = UIImagePickerController()
imagePicker.sourceType = sourceType
imagePicker.mediaTypes = [UTType.image.identifier, UTType.movie.identifier]
imagePicker.cameraDevice = .rear
return imagePicker
}
func updateUIViewController(_ uiViewController: UIImagePickerController, context: Self.Context) {
}
}
Then I have my widget:
struct CameraWidgetControl: ControlWidget {
var body: some ControlWidgetConfiguration {
StaticControlConfiguration(
kind: "com.myCompany.myAppName.lock-screen") {
ControlWidgetButton(action: MyAppCaptureIntent()) {
Label("Capture", systemImage: "camera.shutter.button.fill")
}
}
}
}
My AppIntent:
struct MyAppContext: Codable {}
struct MyAppCaptureIntent: CameraCaptureIntent {
typealias AppContext = MyAppContext
static let title: LocalizedStringResource = "MyAppCaptureIntent"
static let description = IntentDescription("Capture photos and videos with MyApp.")
@MainActor
func perform() async throws -> some IntentResult {
.result()
}
}
The Issue
LockedCameraCapture Widget does not launch my app when tapped from locked screen. You get the Face ID prompt and takes you to just Home Screen. But when the same widget is in the Control Center, it launches the app successfully.
Error Message
When tapped on Lock Screen, I get the following error code:
LaunchServices: store ‹private > or url ‹private > was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database"
UserInfo=&NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler}

Things I tried
Widget image displays correctly
App ID and the Provisioning Profile seem to be fine since they work fine when the same code injected in to AVCam sample app and when used the same App ID's.
AppIntent file contains the target memberships of the Lock Screen capture and Widget
Apple compiles without errors or warnings.
I'm writing a program to control a PTZ camera connected via USB.
I can get access to target camera's unique_id, and also other infos provided by AVFoundation. But I don't know how to locate my target USB device to send a UVC ControlRequest.
There's many Cameras with same VendorID and ProductID connected at a time, so I need a more exact way to find out which device is my target.
It looks that the unique_id provided is (locationID<<32|VendorID<<16|ProductID) as hex string, but I'm not sure if I can always assume this behavior won't change.
Is there's a document declares how AVFoundation generate the unique_id for USB camera, so I can assume this convert will always work? Or is there's a way to send a PTZ control request to AVCaptureDevice?
https://stackoverflow.com/questions/40006908/usb-interface-of-an-avcapturedevice
I have seen this similar question. But I'm worrying that Exacting LocationID+VendorID+ProductID from unique_id seems like programming to implementation instead of interface. So, if there's any other better way to control my camera?
here's my example code for getting unique_id:
//
// camera_unique_id_test.mm
//
// 测试代码:使用C++获取当前系统摄像头的AVCaptureDevice unique_id
//
// 编译命令:
// clang++ -framework AVFoundation -framework CoreMedia -framework Foundation
// camera_unique_id_test.mm -o camera_unique_id_test
//
#include <iostream>
#include <string>
#include <vector>
#import <AVFoundation/AVFoundation.h>
#import <Foundation/Foundation.h>
struct CameraInfo {
std::string uniqueId;
};
std::vector<CameraInfo> getAllCameraDevices() {
std::vector<CameraInfo> cameras;
@autoreleasepool {
NSArray<AVCaptureDevice*>* devices =
[AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo];
AVCaptureDevice* defaultDevice =
[AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
// 遍历所有设备
for (AVCaptureDevice* device in devices) {
CameraInfo info;
// 获取unique_id
info.uniqueId = std::string([device.uniqueID UTF8String]);
cameras.push_back(info);
}
}
return cameras;
}

std::vector<CameraInfo> cameras = getAllCameraDevices();

Fundamentally, my questions are: is there a known transform I can apply onto a given (pixel) position (passed into a Metal Fragment Function) to correctly sample a texture provided by the main cameras + processed by a Vision request. If so, what is it? If not, how can I accurately sample my masks?
My goal is to highlight people in a Vision Pro app using Compositor Services.
To start, I asynchronously receive camera frames for the main left and right cameras. This is the breakdown of the specific CameraVideoFormat I pass along to the CameraFrameProvider:
minFrameDuration: 0.03
maxFrameDuration: 0.033333335
frameSize: (1920.0, 1080.0)
pixelFormat: 875704422
cameraType: main
cameraPositions: [left, right]
cameraRectification: mono
From each camera frame sample, I extract the left and right buffers (CVReadOnlyPixelBuffer.withUnsafebuffer ==> CVPixelBuffer).
I asynchronously process the extracted buffers by performing a VNGeneratePersonSegmentationRequest on both of them:
// NOTE: This block of code and all following code blocks contain simplified representations of my code for clarity's sake.
var request = VNGeneratePersonSegmentationRequest()
request.qualityLevel = .balanced
request.outputPixelFormat = kCVPixelFormatType_OneComponent8
...
let lHandler = VNSequenceRequestHandler()
let rHandler = VNSequenceRequestHandler()
...
func processBuffers() async {
try lHandler.perform([request], on: lBuffer)
guard let lMask = request.results?.first?.pixelBuffer else {...}
try rHandler.perform([request], on: rBuffer)
guard let rMask = request.results?.first?.pixelBuffer else {...}
appModel.latestPersonMasks = (lMask, rMask)
}
I store the two resulting CVPixelBuffers in my appModel. For both of these buffers aka grayscale masks:
width (in pixels) = 512
height (in pixels) = 384
byters per row = 512
plane count = 0
pixel format type = 1278226488
I am using Compositor Services to render my content in Immersive Space. My implementation of Compositor Services is based off of the same code from Interacting with virtual content blended with passthrough.
Within the Shaders.metal, the tint's Fragment Shader is now passed the grayscale masks (converted from CVPixelBuffer to MTLTexture via CVMetalTextureCacheCreateTextureFromImage() at the beginning of the main render pipeline).
fragment float4 tintFragmentShader(
TintInOut in [[stage_in]],
ushort amp_id [[amplification_id]],
texture2d<uint> leftMask [[texture(0)]],
texture2d<uint> rightMask [[texture(1)]]
)
{
if (in.color.a <= 0.0) {
discard_fragment();
}
float2 uv;
if (amp_id == 0) { // LEFT
uv = ??????????????????????;
} else { // RIGHT
uv = ??????????????????????;
}
constexpr sampler linearSampler (mip_filter::linear, mag_filter::linear, min_filter::linear);
// Sample the PersonSegmentation grayscale mask
float maskValue = 0.0;
if (amp_id == 0) { // LEFT
if (leftMask.get_width() > 0) {
maskValue = rightMask.sample(linearSampler, uv).r;
}
} else { // RIGHT
if (rightMask.get_width() > 0) {
maskValue = rightMask.sample(linearSampler, uv).r;
}
}
if (maskValue > 250) {
return (1.0, 1.0, 1.0, 0.5)
}
return in.color;
}
I need to correctly sample the masks for a given fragment.
The LayerRenderer.Layout is set to .layered. From Developer Documentation.
A layout that specifies each view’s content as a slice of a single texture.
Using the Metal debugger, I know that the final render target texture for each view / eye is 1888 x 1792 pixels, giving an aspect ratio of 59:56.
The initial CVPixelBuffer provided by the main left and right cameras is 1920x1080 (16:9).
The grayscale CVPixelBuffer returned by the VNPersonSegmentationRequest is 512x384 (4:3).
All of these aspect ratios are different.
My questions come down to: is there a known transform I can apply onto a given (pixel) position to correctly sample a texture provided by the main cameras + processed by a Vision request. If so, what is it? If not, how can I accurately sample my masks?
Within the tint's Vertex Shader, after applying the modelViewProjectionMatrix, I have tried every version I have been able to find that takes the pixel space position (= vertices[vertexID].position.xy) and the viewport size (1888x1792) to compute the correct clip space position (maybe = pixel space position.xy / (viewport size * 0.5)???) of the grayscale masks but nothing has worked. The "highlight" of the person segmentations is off: scaled a little too big, offset little to far up and off to the side.
The iPhone 17’s front camera with the new 18MP square sensor and iOS 26’s Center Stage feature can auto-rotate between portrait and landscape like the native iOS Camera app.
Is there a Swift or AVFoundation API that allows developers to manually control front camera orientation in the same way the native Camera app does? Or is this auto-rotation strictly handled by the system without public API access?
Hi,
I'm a fan of the gallery in vision pro which has video as well as still photography but I'm wondering if Apple has considered adding the projected media tags to heic so that we can go that next step from Spatial photos to Immersive photos. I have a device that can give me 12k x 6k fisheye images in HDR, but it can't do it at a framerate or resolution that's good enough for video, so I want to cut my losses and show off immersive photos instead. Is there something Apple is already working on for APMP stills or should I create my own app that reads metadata inside a HEIC that I infer in a similar way to the demo "ProjectedMediaConversion" is doing for Video. It would be great to have 180VR photos, which could show as Spatial in a gallery view, but going immersive would half-surround you instead of floating in the blurred view. I think that would be a pretty amazing effect.

In what scenario will an app receive the limitExceeded PHPhotosError code? This case was added in iOS 26.1 and is not currently documented. What PhotoKit APIs can encounter this error and how should it be handled?
Problem Description
(1) I am using ARKit in an iOS app to provide AR capabilities. Specifically, I'm trying to use the ARSession's captureHighResolutionFrame(using:) method to capture a high-resolution frame along with its corresponding depth data:
open func captureHighResolutionFrame(using photoSettings: AVCapturePhotoSettings?) async throws -> ARFrame
(2) However, when I attempt to do so, the call fails at runtime with the following error, which I captured from the Xcode debugger:
[AVCapturePhotoOutput capturePhotoWithSettings:delegate:] settings.depthDataDeliveryEnabled must be NO if self.isDepthDataDeliveryEnabled is NO
Code Snippet Explanation
(1) ARConfig and ARSession Initialization
The following code configures the ARConfiguration and ARSession. A key part of this setup is setting the videoFormat to the one recommended for high-resolution frame capturing, as suggested by the documentation.
func start(imagesDirectory: URL, configuration: Configuration = Configuration()) {
// ... basic setup ...
let arConfig = ARWorldTrackingConfiguration()
arConfig.planeDetection = [.horizontal, .vertical]
// Enable various frame semantics for depth and segmentation
if ARWorldTrackingConfiguration.supportsFrameSemantics(.smoothedSceneDepth) {
arConfig.frameSemantics.insert(.smoothedSceneDepth)
}
if ARWorldTrackingConfiguration.supportsFrameSemantics(.sceneDepth) {
arConfig.frameSemantics.insert(.sceneDepth)
}
if ARWorldTrackingConfiguration.supportsFrameSemantics(.personSegmentationWithDepth) {
arConfig.frameSemantics.insert(.personSegmentationWithDepth)
}
// Set the recommended video format for high-resolution captures
if let videoFormat = ARWorldTrackingConfiguration.recommendedVideoFormatForHighResolutionFrameCapturing {
arConfig.videoFormat = videoFormat
print("Enabled: High-Resolution Frame Capturing by selecting recommended video format.")
}
arSession.run(arConfig, options: [.resetTracking, .removeExistingAnchors])
// ...
}
(2) Capturing the High-Resolution Frame
The code below is intended to manually trigger the capture of a high-resolution frame. The goal is to obtain both a high-resolution color image and its associated high-resolution depth data. To achieve this, I explicitly set the isDepthDataDeliveryEnabled property of the AVCapturePhotoSettings object to true.
func requestImageCapture() async {
// ... guard statements ...
print("Manual image capture requested.")
if #available(iOS 16.0, *) { // Assuming 16.0+ for this API
if let defaultSettings = arSession.configuration?.videoFormat.defaultPhotoSettings {
// Create a mutable copy from the default settings, as recommended
let photoSettings = AVCapturePhotoSettings(from: defaultSettings)
// Explicitly enable depth data delivery for this capture request
photoSettings.isDepthDataDeliveryEnabled = true
do {
let highResFrame = try await arSession.captureHighResolutionFrame(using: photoSettings)
print("Successfully captured a high-resolution frame.")
if let initialDepthData = highResFrame.capturedDepthData {
// Process depth data...
} else {
print("High-resolution frame was captured, but it contains no depth data.")
}
} catch {
// The exception is caught here
print("Error capturing high-resolution frame: \(error.localizedDescription)")
}
}
}
// ...
}
Issue Confirmation & Question
(1) Through debugging, I have confirmed the following behavior: If I call captureHighResolutionFrame without providing the photoSettings parameter, or if photoSettings.isDepthDataDeliveryEnabled is set to false, the method successfully returns a high-resolution ARFrame, but its capturedDepthData is nil.
(2) The error message clearly indicates that settings.depthDataDeliveryEnabled can only be true if the underlying AVCapturePhotoOutput instance's own isDepthDataDeliveryEnabled property is also true.
(3) However, within the context of ARKit and ARSession, I cannot find any public API that would allow me to explicitly access and configure the underlying AVCapturePhotoOutput instance that ARSession manages.
(4) My question is:
Is there a way to configure the ARSession's internal AVCapturePhotoOutput to enable its isDepthDataDeliveryEnabled property? Or, is simultaneously capturing a high-resolution frame and its associated depth data simply not a supported use case in the current ARKit framework?
I have the main app that saves preferences to UserDefaults.standard. So I have this one preference that the user is able to toggle - isRawOn
UserDefaults.standard.set(self.isRawOn, forKey: "isRawOn")
Now, I have LockedCameraCaptureExtension which is required know if that above setting on or off during launch. Also if it's toggled within the extension, the main app should know about it on the next launch.
The main app and the extension runs on separate containers and the preferences are not shared due to privacy reasons.
Apple mentions of using appContext of CameraCaptureIntent, but not sure how above scenario is possible through that....unless I am missing something.
Apple Reference
What I have for CameraCaptureIntent:
@available(iOS 18, *)
struct LaunchMyAppControlIntent: CameraCaptureIntent {
typealias AppContext = MyAppContext
static let title: LocalizedStringResource = "LaunchMyAppControlIntent"
static let description = IntentDescription("Capture photos with MyApp.")
@MainActor
func perform() async throws -> some IntentResult {
.result()
}

In my app, I use api provided in Photos framework to delete specified photo.
But after upgrading to iOS 26, the delete function in some iOS device no longer work.
The api will never triggers the system confirmation dialog, and the completionHandler is never called.
In the iOS Photos app, deletion works correctly on the same assets, but calling the API from my app does not work.
Steps to Reproduce
Make sure the app has Full Photo Library Access.
Execute the following code:
PHPhotoLibrary.shared().performChanges({
let assetsToBeDeleted = PHAsset.fetchAssets(withLocalIdentifiers: delUrls, options: nil)
PHAssetChangeRequest.deleteAssets(assetsToBeDeleted)
}, completionHandler: completionHandler)
Expected Behavior
The system should present a confirmation dialog asking the user to delete the selected photos.
After the user confirms, the deletion should occur, and the completionHandler should be called with success or error.
Actual Behavior
The system delete confirmation dialog does not appear.
The completionHandler is never called.
Environment
iOS Versions: 26.1 / 26.0.1
It looks like api bug.
I want to check Is it a know issue and will be fixed. Thanks
If the app is launched from LockedCameraCapture and if the settings button is tapped, I need to launch the main app.
CameraViewController:
func settingsButtonTapped() {
#if isLockedCameraCaptureExtension
//App is launched from Lock Screen
//Launch main app here...
#else
//App is launched from Home Screen
self.showSettings(animated: true)
#endif
}
In this document:
https://developer.apple.com/documentation/lockedcameracapture/creating-a-camera-experience-for-the-lock-screen
Apple asks you to use:
func launchApp(with session: LockedCameraCaptureSession, info: String) {
Task {
do {
let activity = NSUserActivityTypeLockedCameraCapture
activity.userInfo = [UserInfoKey: info]
try await session.openApplication(for: activity)
} catch {
StatusManager.displayError("Unable to open app - \(error.localizedDescription)")
}
}

However, the documentation states that this should be placed within the extension code - LockedCameraCapture. If I do that, how can I call that all the way down from the main app's CameraViewController?
On iOS 26.1, this throws on the 2020 iPad Pro (4th gen) but works fine on an M4 iPad Pro or iPhone 15 Pro:
guard let device = AVCaptureDevice.default(.builtInLiDARDepthCamera, for: .video, position: .back) else {
throw ConfigurationError.lidarDeviceUnavailable
}
It's just the standard code from Apple's own sample code so obviously used to work:

Does it fail because Apple have silently dumped support for the older LiDAR sensor used prior to the M4 iPad Pro, or is there another reason? What about the 5th and 6th gen iPad Pro, does it still work on those?
