I am developing a parental control app using Flutter and platform channels to integrate with the Screen Time API on iOS. The app has two interfaces - one for the parent and one for the child. I have set up Family Sharing correctly and installed the app on both the parent's and child's devices. However, I am encountering some issues with the Family Activity Selection feature. It's worth noting that I am a Flutter developer with limited knowledge of Swift and iOS development, so if my issues stem from a mistake I made, please forgive me. The problems I am facing are as follows: When calling the family activity selection, the list of apps shown in the apps sheet is from the parent's device, and no apps from the child's device are displayed. I have double-checked that Family Sharing and other necessary configurations are set up correctly, including the family control capability. Even if I select apps on the parent's device, the selected apps are not returned in the result. The returned array is empty. Additionally, there is no close or done button on the sheet, and drag-to-dismiss is not working either. This might be an issue with the way I have written the code (most of the native code was generated by AI assistants like Claude and GPT, as I am a Flutter developer with limited knowledge of Swift and iOS development). I have tested other parental control apps that use the Screen Time API and observed the same issue, where the parent's apps are shown on the parent's device instead of the child's apps. For more context, I have provided the relevant code snippet below: import Flutter import FamilyControls import ManagedSettings import SwiftUI class FamilyActivityHandler: NSObject, FlutterPlugin { // ... private func openFamilyActivityPicker(result: @escaping FlutterResult) { let store = ManagedSettingsStore() let selection = FamilyActivitySelection() // Adjusting for UIWindowScene for iOS 15 and later guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene, let window = windowScene.windows.first else { result(FlutterError(code: "NO_WINDOW_SCENE", message: "No window scene found", details: nil)) return } let viewController = UIHostingController(rootView: FamilyActivityPicker(selection: .constant(selection))) viewController.modalPresentationStyle = .formSheet window.rootViewController?.present(viewController, animated: true, completion: nil) DispatchQueue.main.async { let applications = selection.applicationTokens let categories = selection.categoryTokens let webDomains = selection.webDomainTokens store.shield.applications = applications.isEmpty ? nil : applications store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set()) store.shield.webDomains = webDomains // Custom method to generate descriptive strings for tokens let applicationsDescription = applications.map { token in // Implement a custom description method or use an identifier property "\(token)" } let categoriesDescription = categories.map { token in // Implement a custom description method or use an identifier property "\(token)" } let webDomainsDescription = webDomains.map { token in // Implement a custom description method or use an identifier property "\(token)" } let resultDict: [String: Any] = [ "applications": applicationsDescription, "categories": categoriesDescription, "webDomains": webDomainsDescription ] result(resultDict) } } } I would greatly appreciate any guidance or insights from the community on how to resolve these issues and properly implement the Family Activity Selection feature using the Screen Time API in a Flutter app with platform channels.

I am currently debugging an issue with DeviceActivityMonitor where the threshold is reached even though the target app (e.g. Instagram) is not being used actively. I noticed that the device with the unexpected behavior had the instagram.com website opened in the Safari web browser (among hundreds of other tabs). That tab was not actively used either (not in foreground, Safari app neither used). However, I was wondering if it can happen that this website is contributing towards the threshold as well even though it is in background and not used? Otherwise I cannot explain myself this strange behavior.

Hello, I am working on a screen time manager that can block certain apps. I want this to work by allowing a certain number of 5-minute sessions per day. For each app the user selects, I would like to store the number of sessions remaining for that app in a dictionary. Currently, I am storing them in a dictionary of type <AppToken: Int>. However, I would like to store this dictionary to UserDefaults, and it doesn't seem like it is possible to store the type AppToken to UserDefaults. I was wondering how I could go about storing the AppTokenas a String and maybe saving to UserDefaults as a <String: Int> instead? Thanks.

Hi, I use ScreenTime API for proving feature of hiding other installed apps in the iOS device. 
Specifically I set applications I want to hide to this property of ManagedSettingsStore.application.blockedApplications. Documentation to this propery says The system hides blocked applications and prevents the user from launching them. There is no any limitations or deprecation labels, api available starting iOS 15. My app is in the AppStore and works good, but I received reject for app update saying: The app uses public APIs in an unapproved manner, which does not comply with guideline 2.5.1. Specifically, your app still uses Screentime API to hide apps from user. Since there is no accurate way of predicting how an API may be modified and what effects those modifications may have, unapproved uses of public APIs in apps is not allowed. This sounds odd to me as feature is documented, not marked as deprecated and confirmed on forum by Apple Engineer it’s available for developers. Additionally I can’t find any public information about “unapproved uses of public APIs” that reviewer refers to. So there are literally no reason to reject my app as feature is documented and I use it as it's prescribed. The only public requirement for the developers found in Apple Review Guidelines and Apple Developer Program License Agreement is to use public API, there is no term "unapproved uses of public APIs". After long conversation with reviewer I submitted appeal but review board didn't provide any clarity and declines my appeal with exactly the same response without clarifying situation and referring to 2.5.1 that is actually not applicable. Looking forward to finding any useful information, experiences from other developers, or clarifications from Apple Engineers.

As per our code, we have the apps to be shielded whenever the threshold is reached. According to this use-case, our code in DeviceActivityExtension looks something like: override func eventDidReachThreshold(_ event: DeviceActivityEvent.Name, activity: DeviceActivityName) { super.eventDidReachThreshold(event, activity: activity) defaults?.setValue(event.rawValue, forKey: "appLimitEventName") defaults?.setValue(true, forKey: "appLimitReached") defaults?.synchronize() // using darwinNotificationCenter to trigger callback in the application let darwinNotificationCenter = DarwinNotificationsManager.sharedInstance() darwinNotificationCenter.postNotification(withName: "nextAppLimitInitiated") // using Notifications to debug since print doesn't work scheduleNotification(with: "interval threshold reached") } And in our application, we have the shielding logic in place, init() { let darwinNotificationCenter = DarwinNotificationsManager.sharedInstance() darwinNotificationCenter.register(forNotificationName: "nextAppLimitInitiated"){ print("callback received") let appLimitReached = self.defaults?.bool(forKey: "appLimitReached") let appLimitEventName = self.defaults?.string(forKey: "appLimitEventName") if appLimitReached ?? false, appLimitEventName != "" { // this sends the notification when callback is received self.scheduleNotification(with: "init start") self.defaults?.setValue(false, forKey: "appLimitReached") guard var dataArray = self.defaults?.array(forKey: "appLimitdataArray"), !dataArray.isEmpty else { return } let appLimitData = dataArray.first as! NSDictionary let appLimitKey = appLimitData["appLimitId"] as! String let data = self.getSchedule(key: appLimitEventName ?? "") if let appTokens = data?.applicationTokens { for token in appTokens { if !self.applicationTokens.contains(appTokens) { self.applicationTokens.insert(token) } } } self.store.shield.applications = self.applicationTokens self.store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(self.categoryTokens, except: Set()) dataArray.removeFirst() //dataArray.append(appLimitData) self.defaults?.set(dataArray, forKey: "appLimitdataArray") self.initiateMonitoring(initiateAgain: true) self.scheduleNotification(with: "init end") } } } This works as expected for multiple App Limits but only when the device is connected to the Xcode. If we disconnect the device from Xcode/ stop application from Xcode/ try in release mode, the callback is not received from extension to the app/init block. When the device is connected to Xcode, if the apps hit the threshold, they are shielded automatically. But if the device is disconnected/ app is in release mode, the apps are not shielded automatically even after the threshold is reached. It is shielded later only after opening our app once. Please let me know if I'm doing anything wrong in receiving callback or in my shielding logic. If I need to place the shielding logic in the extension, please tell me how I can handle multiple appTokens.

I have two repeating DeviceActivitySchedules running in my app and noticed a super strange behavior: whenever I modify Screen Time API permission settings (granting an additional app permission, or removing permission for a different app (completely different unrelated screen time apps from App Store)) all my DeviceActivitySchedules are cancelled and the intervalDidEnd callbacks are called my permission is not modified in this scenario this is a super strange and unexpected behavior is anyone able to reproduce this? for me this happens 100% of the times I do this any known workarounds?

Hello, I am using a DeviceActivityEvent to limit access to an app after the user has spent x minutes on it. Sometimes it can happen that a DeviceActivitySchedule spans from 11:55pm - 12:25am (just an example). In these cases, I have noticed, the DeviceActivityMonitorExtension’s eventDidReachThreshold is not called after the user has reached the threshold time interval in the observed app. I assume this is because we have transitioned over midnight and something weird happens to the DeviceActivitySchedule. I’ve tried adding the day components to the DeviceActivitySchedule as well, but then it fails completely. Any advice how to handle this? I could, of course, create two separate DeviceActivitySchedules: one for before midnight, and one for after. But depending on the user’s real app usage that could lead to slightly different (and unexpected) behavior.

If we want to un-shield category/application for particular schedule, then what is the mechanism for this, as for now we are using ManagedSettingsStore().shield.applications = nil and ManagedSettingsStore().shield.applicationCategories = nil, which is actually un-shielding all category/applications without considering the selection of category/application for that schedule. What is the best approach to handle multiple schedules for shielding of apps?

How can I add an X as close button on the FamilyActivityPicker Toolbar? Desired effect see image

Update 1: Seems like app limits do work, but they don't account for time spent already in the day (only counts it since it first was scheduled? - but just guessing). This seems to be the change in behavior that is making it seem like broken. I have an app that uses individual FamilyControls / Screen Time authorization. I am still investigating but reporting ASAP. Will add feedback and more later. I am not sure what's going on, but so far: App limits generally work fine throughout the day(?) At around 9 PM they stop working if I clear ManagedSettingStore/DeviceActivityCenter (it might be unrelated to the time, but just clearing, but this is just what I know so far) I tried setting app limits from Apple's Setting app (so I could see if it's not just my app, and that system could have issues) and it crashes. The whole Settings app freezes and then crashes. (edit: after some freezing, including in the app picker, I was able to set a limit and it worked...did notice some odd behavior where 1 minute break did not work, but selecting 15 minute break did work) going to also update: FB13688616

It's no secret, the Screen Time/Family Controls API is incredibly challenging to figure out. If you want to talk with other people building on the API, join the discord here: https://discord.gg/sjxhKWgry4 I want to connect with other people building so I made a discord where we can discuss challenges, updates & questions in more depth.

I'm using the Screen Time API to shield apps the user selects. The problem is, that the apps are always shielded, even outside of the schedule. Here is my function initiateMonitoring: func initiateMonitoring(scheduleStart: DateComponents, scheduleEnd: DateComponents) { let schedule = DeviceActivitySchedule( intervalStart: scheduleStart, intervalEnd: scheduleEnd, repeats: true ) let center = DeviceActivityCenter() do { try center.startMonitoring(.daily, during: schedule) logger.log("STARTED MONITORING") } catch { logger.log("FAILED MONITORING: \(error.localizedDescription)") } } The expected result should be that the selected Apps should be blocked during the schedule the user specified, but not outside the schedule, but it is blocked 24/7. I've experimented with the DateComponents, but the issue may be somewhere else. What's maybe interesting is, I tried Logging the DeviceActivityMonitor and somehow it doesn't get called. The logging-output from initiateMonitoring is printed in the console, but for the DeviceActivityMonitor it's not. I implemented it as recommended as a separate Extension Target. For more context, here is my DeviceActivityMonitor: class DeviceActivityMonitorExtension: DeviceActivityMonitor { let store = ManagedSettingsStore() let logger = Logger() override func intervalDidStart(for activity: DeviceActivityName) { super.intervalDidStart(for: activity) logger.log("INTERVAL STARTED") let model = ShieldManager.shared let applications = model.selectionToDiscourage.applicationTokens let categories = model.selectionToDiscourage.categoryTokens let webCategories = model.selectionToDiscourage.webDomainTokens store.shield.applications = applications.isEmpty ? nil : applications store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set()) store.shield.webDomains = webCategories.isEmpty ? nil : webCategories } ... What's confusing me is that the apps are in fact shielded, so the MonitorExtension should be called, but neither the logging works nor my separate ShieldConfigurationExtension, maybe the issues are connected... Any help would be gladly appreciated!

I am currently developing an app to help people focus on their work. I use familycontrols , managedsettings and devie activity to develop it. I am currently facing an issue where I would like to hide the app selected by the user from the main screen and resource library. But I did not find any relevant information in the document. Who can help me.

There is a way to allow DeviceActivityMonitor to make UI changes? Currently I have some code in the intervalDidStart and intervalDidEnd that updates Core Data entities, and it works correctly. However, the changes are only reflected if the app is terminated and opened again. Thus, if the app is opened and one of the methods inside the DeviceActivityMonitor is being called, the UI won't be updated. PS: I am using @FetchRequest to retrieve the core data entities called BlockEntity, and I have a little circle in the UI which should indicate the status of the block: active/inactive, so it would be nice to update the color in real time when intervalDidStart or intervalDidEnd are called.

I am trying to understand how to approach 'x minute' pauses for a DeviceActivitySchedule. For instance, I would like to let the user pause for 5 minutes from an active schedule (meaning un-shielding the apps and re-applying the shield after the 5 min has passed). The only way that came to my mind was calling the following: Calling .startMonitoring to start monitoring a new event with the same apps starting .now and ending .now + 5 minutes; Calling in the intervalDidStart, store.shield.applications.subtract(apps) so that the apps are removed from the shield. Calling in the intervalDidEnd, store.shield.applications = apps so that the apps are now shielded again. The problem is that, from the Apple Developer Documentation: The minimum interval length for monitoring device activity is fifteen minutes. So the minimum pause I could offer to the user would be 15 minutes. And that tells me this approach is most likely wrong, because all other Screen Time apps, like Opal, Jomo, AppBlock offer also 5 min pause. Does anyone know / can think of a different and better approach?

An app that uses screen time API. After asking for permission and receiving them works, everything generally work, shields applications etc.. Upon new version update (manually update from testFlight old version or App Store) I get an error message, I can then update again without any error but the permissions are revoked and I have to ask for them again. shielding stopes. This happens randomly on TestFlight or App Store and the permissions Did anyone encounter this or solved this? this seems to have started a month ago but maybe I just missed it before

Anyone had any luck modifying any of the Activity pickers with the view modifer. We've tried preferredColorScheme(_:) with no luck. Stuck with black icons half the time - which doesn't match our UI. We've had even less luck modifying the activityPicker sheet view to match our UI. A gigantic 'Choose Activity' sits right in the middle of our activity selection page which already has our own specific headers. Not to mention trying add accessibility option into these views. Anyone had better luck modifiying the activity picker views?

Hello, I want to make a simple project that simply displays the user's current daily ScreenTime. I believe you may be able to do the functionality I want with: FamilyControls or ScreenTime. I believe that you may need to pay for the paid developer account in order to access the FamilyControl framework. I am having trouble finding guidance as to how I would do this as most reddit/stackoverflow posts are incomplete with answers and I cannot find demos/code examples/tutorials/sample usage anywhere on google. I would greatly appreciate any help and guidance. If the solution requires the paid developer tier, I am fine with that. Thank you in advance
