Hi, I’ve developed a photo app that includes a photo deletion feature. Some users have reported encountering PHPhotosError.operationInterrupted (3301) when attempting to delete photos. Initially, I suspected that some of the assets might have a sourceType of typeiTunesSynced, since the documentation notes that iTunes-synced assets cannot be edited or deleted. However, after checking the logs, all of the assets involved are of typeUserLibrary. Additionally, the user mentioned that some photos in the iPhone Photos do not show a delete button. I’m unsure whether the absence of the delete button is related to the 3301 error. I’d like to confirm the following: Under what conditions does PHPhotosError.operationInterrupted (3301) occur, and how should it be handled? Why do some photos in the iPhone Photos not show a delete button? The code for deleting photos is as follows: PHPhotoLibrary *library = [PHPhotoLibrary sharedPhotoLibrary]; [library performChanges:^{ PHFetchResult *assetsToBeDeleted = [PHAsset fetchAssetsWithLocalIdentifiers:delUrls options:nil]; if (assetsToBeDeleted) { [PHAssetChangeRequest deleteAssets:assetsToBeDeleted]; } } completionHandler:^(BOOL success, NSError *error) {

Hey, Quick question. I noticed that Adobe's new app, Project Indigo, allows you to open the app using the Camera Control button. However, when your device is locked it just shows this screen: Would this normally be approved by the Appstore approval process? I ask because I would like to do something similar with my camera app. I know that this is not the best user experience, but my apps UI is not built in Swift and I don't have the resources to build the UI again. At least this way the user experience would be improved from what it is now, where users cannot even launch the app. I get many requests per week about this feature and would love to improve the UX for my users, even if it's not the best possible. Thanks, Alex

We are facing a strange issue where a small portion of our large userbase can not start the capture session in our app, as it gets interrupted with the following reason: AVCaptureSessionInterruptionReasonVideoDeviceNotAvailableWithMultipleForegroundApps Our users are all from iPhones, no one is using an iPad. Just to be sure we have set session.isMultitaskingCameraAccessEnabled = true but it does not seem to make any difference. Another weird interruption we are seeing

We are facing a strange issue where a small portion of our large userbase can not start the capture session in our app, as it gets interrupted with the following reason: AVCaptureSessionInterruptionReasonVideoDeviceNotAvailableWithMultipleForegroundApps Our users are all from iPhones, no one is using an iPad. Just to be sure we have set session.isMultitaskingCameraAccessEnabled = true but it does not seem to make any difference. Another weird scenario we are seeing on an even smaller number of users is that the following call: AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .back) returns nil. A quick look at our error reports show this happening on iPhone XR, 13 and 14 models. They should all support this device type. Any help on investigating these issue would be greatly appreciated!

Can i use iokit usb lib to disable build-in camera?

I developed a driverkit extension based on overriding-the-default-usb-video-class-extension, but the link didn’t give the details of realization. I asked DTS who gave two tips: 1, Do you also have a CMIO extension to load in place of the default overriding-the-default-usb-video-class-extension 2, Your DriverKit extension’s info.plist is also missing the CameraAssistantBundleID. I want to know why a driverkit extension needs a CMIO extension, what’s the data and control flow?
