“DeviceActivityReport”

There have been several posts (i.e. here, here) about the lagginess of the DeviceActivityReport extension. Often it takes a few seconds for the view to load, or sometimes doesn't show up at all. I've confirmed this is not a case of excessive memory usage in the extension (exceeding 100MB), because I've profiled the extension and it consistently maxes out at 10MB. I've placed a loading screen behind the DeviceActivityReport inside a ZStack in the host app in order to see if the lag is because it takes some time for the extension to spin up - but the loading screen does not appear, indicating that the extension is running right away, but receiving the view from the extension in the host app is where the lag happens. It's been extremely difficult to debug because the lag only occurs a fraction of the time, and DeviceActivityReport is pretty much a black box. There's no documentation about how the host app and extension actually communicate. I've also combed through the logs using the C

Hello, I want to echo the DeviceActivityReport concurrency problems flagged in https://developer.apple.com/forums/thread/720549, and ask a related question. (Thanks to Kmart and other Apple dev support folks who have been monitoring these forums and responding diligently.) I would like to display daily and weekly stats in the same view, broken down by specific apps (as in the native Screen Time). However, instantiating multiple DeviceActivityReport objects with different filters and/or different contexts leads to confusion, where the two views will incorrectly and intermittently swap data or duplicate data where it shouldn't (seemingly upon some interval when the extension provides fresh data). There isn't documentation on how to display multiple reports at once. Is the idea that logic for multiple reports should be embedded within the extension itself in the makeConfiguration() function and there should only be a single DeviceActivityReport in the main App, or is this a bug? Even w

DeviceActivityReport view often shows up blank in the host app. What's the best way to refresh the view when this occurs?

I want to add a widget to my app that will display the # of pickups the user has for the day. I have the DeviceActivityReport working in the main app but can't get it to display in the widget since it is not a supported view for widgets. Is there any workaround for getting this view to the widget? I tried converting the DeviceActivityReport view to a UI image thinking maybe that would be a way to use a widget approved view type but ImageRenderer seems to fail to render an image for the view (which is just a Text view). To summarize my questions: Is it possible to display a DeviceActivityReport in a widget? If so, what is the best practice? Is converting the DeviceActivityReport view into an image and displaying that in a widget an option? Here's my attempt to convert the DeviceActivityReport view into a UIImage: import SwiftUI import _DeviceActivity_SwiftUI struct PickupsDeviceActivityReport: View { @State private var context: DeviceActivityReport.Context = .totalA

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() hostingCo

The DeviceActivityReport is often laggy or sometimes doesn't show up at all. Quitting and re-opening the app usually fixes this problem. I'm wondering, is there a way to programmatically terminate and then re-launch the DeviceActivityReport App Extension from the host app? This way, that could act as a refresh when the DeviceActivityReport fails to show up.

Hello everyone, As stated in DeviceActivityReport's documentation, when we create a report, the system asks my app’s device activity report extension to provide a View representing the user’s device activity. However, is there a way to send the data to a server in order to display the user's data on a web application so the parent can have access to this data at anytime from anywhere? Best regards, Ben

Pretty much as per the title and I suspect I know the answer. Given that Foundation Models run on device, is it possible to use Foundation Models framework inside of a DeviceActivityReport? I've been tinkering with it, and all I get is errors and Sandbox restrictions. Am I missing something? Seems like a missed trick to utilise on device AI/ML with other frameworks.

I've been experiencing some serious performance issues with DeviceActivityReport. Their severity tends to vary across devices - for some of my users it's really bad and for some it's mostly fine - but every device seems to experience these issues at some point. 1. DeviceActivityReport is completely blank. Often on launch, the DeviceActivityReport is completely blank and the only way to make it show up is to click back and forth between tabs, or quit the app and re-open it. Sometimes, it will show up after one or two seconds, but that is still a bad user experience. When looking at logs during this issue, I can see that makeConfiguration still runs successfully and returns a value, so I suspect the issue is with the rendering of the View in the App Extension. 2. Gestures are slow to register, or can't register at all. For example, if I place my DeviceActivityReport inside a ScrollView, I cannot scroll if I perform the gesture on the report view. If I try to scroll on the par

There is frequently a delay of a few seconds before a DeviceActivityReport renders its view generated from the DeviceActivityReportExtension. It will also sometimes flash with zero data before hydrating with the real activity data (tested with extension code taken directly from XCode boilerplate) Is there a way to be notified when the DeviceActivityReport renders successfully or is still processing, i.e. so a loading indicator can be presented while the extension runs? Thanks!

Our app uses DeviceActivityReport to display the user’s screen time. The performance of DeviceActivityReport is often very poor. These issue occur commonly: Screen time is reported as 0 minutes DeviceActivityReport View appears completely blank The host app loses connection with the DeviceActivityReport altogether I have implemented several workarounds which only slightly improve the performance, to varying degrees depending on the device iOS: Inside the DeviceActivityReport code - retry fetching screen time data until it returns a non-zero result Implement a “refresh” button which reloads the DeviceActivityReport view from the host app However, due to the sandboxed nature of DeviceActivityReport, there is no way for the host application to tell if the DeviceActivityReport extension is experiencing these performance issues. It results in a really bad user experience. I am building the app with Xcode 14 due to another issue where DeviceActivityReport

My app monitors DeviceActivityEvents with no categories, apps, or websites selected because we want to monitor their time spent on all categories, apps, and websites. This is because my app gives users rewards for keeping their total Screen Time low. Unfortunately, it has been seemingly impossible to align the Screen Time shown with DeviceActivityReport to the Screen Time monitored with DeviceActivityMonitor. By default, the DeviceActivityReport captures more Screen Time than the DeviceActivityMonitor by default. But if I try to filter the report by totalActivityDuration on each category, it misses some Screen Time captured by the monitor (like FaceTime, for instance). I simply want to report to the user exactly the Screen Time I am monitoring by default with DeviceActivityMonitor. Is that possible without selecting any categories, apps, or websites in the monitor?

I'd like to allow users to select apps to shield from a DeviceActivityReport (similar to how Apple's Screen Time Settings activity report allows a user to add limits to a selected app in the report. What I need to do is pass an appToken from the DeviceActivityReportExtension to my app. I realize the extension is sandboxed and doesn't allow private data to be seen outside of the sandbox. The docs state: To protect the user’s privacy, your extension runs in a sandbox. This sandbox prevents your extension from making network requests or moving sensitive content outside the extension’s address space. However, tokens aren't sensitive. I want to pass a token set out of the sandboxed extension so users can select certain apps from the report that my app can use for setting limits, etc. I thought using App Groups and saving data with UserDefaults with a suiteName for my app group would do it, but it doesn't appear to allow me to pass the token data. Yes I'm using the same KEY for both as I set a config enum

tl;dr can we use Label(application token) inside of a DeviceActivityReport? I’m working on an app that uses the DeviceActivityReport extension to show a user’s screen time breakdown. The app was working fine in a setup where my main app had the Distribution Family Controls capability and all the extensions had the Development Family Controls capability. However, this caused provisioning issues when I tried to create a test flight build. I then removed the development capabilities from the extensions, and now everything works fine except oddly the Labels in the DeviceActivityReport no longer show anything. They worked fine before, and the same label logic is working 100% fine inside my main app. Anyone encounter this before?

Hello, I have an iOS app using the DeviceActivityReport app extension. Occasionally, the extension gets terminated (likely due to reaching memory limit**), which in turn disrupts the connection with the main app. How can the main app detect when the DeviceActivityReport extension has been terminated due to memory constraints, and what's the best way to re-establish the connection afterward? Thanks in advance for your insights and suggestions! ** I'm also unsure why the extension should be reaching its memory limit. When profiling the extension in XCode, it never reaches above 15MB, and I know the limit is 100MB. It's not doing anything out of the ordinary - and I've seen very similar complaints about DeviceActivityReport terminating on these forums. Any thoughts on how to prevent termination in the first place would also be super helpful!
