We are using AVAssetDownloadURLSession to download content with multiple audio tracks. Still, we are facing an issue where only one audio language is being downloaded, despite explicitly requesting multiple audio languages. However, all subtitle variants are being downloaded successfully.
Issue Details:
Observed Behaviour: When initiating a download using AVAssetDownloadURLSession, only one audio track (Hindi, in this case) is downloaded, even though the content contains multiple audio tracks.
Expected Behaviour: All requested audio tracks should be downloaded, similar to how subtitle variants are successfully downloaded.

Any idea to achieve reliable periodic Bluetooth data retrieval on iOS, even when the app is closed or killed.
**Hi everyone **
We try to add BackgroundAssetExtension to our project, in local testing work fine, but when we try upload app to TestFlight we get some errors that we don't know how to fix.
App
Supported Destinations: iPhone, iPad, Mac(Designed for iPad)
Minimum Deployments: iOS 12
BackgroundAssetExtension
Minimum Deployments: iOS 16.4
Error when try to upload to TestFlight:
"<IDEDistributionIssue: severity(error), error(Error Domain=ContentDelivery Code=90171 \"Asset validation failed\" UserInfo={IDEDistributionIssueSeverity=3, NSLocalizedDescription=Asset validation failed, NSLocalizedRecoverySuggestion=Invalid bundle structure. The \U201cDemo.app/decompressed_data_5.bin\U201d binary file is not permitted. Your app cannot contain standalone executables or libraries, other than a valid CFBundleExecutable of supported bundles.

when we checked archive (Show package contents) that many files like
compressed_data_1.bin
compressed_data_2.bin
compressed_data_3.bin
compressed_data_4.bin
compressed_data_5.bin
compressed_data_6.bin
decompressed_data_1.bin
decompressed_data_2.bin
decompressed_data_3.bin
decompressed_data_4.bin
decompressed_data_5.bin
decompressed_data_6.bin
We added to main target in Build Phase -> Embed ExtensionKit Extensions

We will be appreciate for any suggestions :) If need some additional information let me know :pray:
Hi everyone,
We came an issue that, In some scenarios in our app we cannot fetch any resources from device (Photo and Contact).
One case we catched is putting app in background and spending time in other commonly used apps and coming back to our app cause this issue but there is a small chance that get this issue during using the application.
In cell, we are trying to fetch the image like this
imageFetchTask = Task {
let image = await CompositionRoot.shared.photosManager.image(requestType: .imageCollections, forId: photoAsset.photoId)
self.photoImageView.image(image)
}
and inner layers of this code we get the PHAsset and request image
PHAsset.firstAsset(for: id)
let manager = PHImageManager.default()
manager.requestImage(for: asset, targetSize: request.targetSize, contentMode: .aspectFill, options: request.options) { (image, info) in
continuation.resume(returning: image)
}
We figured out that issue not happening only in Photos also Contacts and
any web request. So any help according to this situation is well appreciated.
Thanks

DeviceActivityReport presents statistics for a device: https://developer.apple.com/documentation/deviceactivity/deviceactivityreport
The problem: DeviceActivityReport can present statistics with a delay for a parent device (when DeviceActivityReport is presenting, the DeviceActivityReportExtension is called to process the statistics). One possible solution is to call DeviceActivityReport periodically throughout the day in a child device. However, the app will not be available all day. Is there any way to run DeviceActivityReport in the background?
I have tried the following approach, but it didn’t work (DeviceActivityReportExtension didnt call):
let hostingController: UIHostingController? = .init(rootView: DeviceActivityReport(context, filter: filter))
hostingController?.view.frame = .init(origin: .zero, size: .init(width: 100, height: 100))
hostingController?.beginAppearanceTransition(true, animated: false)
hostingController?.loadView()
hostingController?.viewDidLoad()
try? await Task.sleep(for: .seconds(0.5))
hostingController?.viewWillAppear(true)
hostingController?.viewWillLayoutSubviews()
try? await Task.sleep(for: .seconds(0.5))
hostingController?.viewDidAppear(true)
try? await Task.sleep(for: .seconds(0.5))
hostingController?.didMove(toParent: rootVC)
try? await Task.sleep(for: .seconds(0.5))
hostingController?.viewWillLayoutSubviews()
hostingController?.viewDidLayoutSubviews()
hostingController?.view.layoutIfNeeded()
hostingController?.view.layoutSubviews()
hostingController?.endAppearanceTransition()
Is there any way to run DeviceActivityReport in the background? (when app is not visible/closed). The main problem is call DeviceActivityReport
