How to play gif in widget? "网易云音乐" and "one widget" can play gif in the widget. can anyone guide me. Thank you

we are seeing what appears to be an internal healthkit error appearing in our app.  not sure if it's connected, but we've mostly seen it reported on devices running ios 16.  even though our app's primary language is japanese, and in all reported occurrences the app was running in japanese, the error message itself appears in english.  searching the error string on the web yields surprisingly few results (including only two mentions on this forum that i could find, neither of which seemed relevant).  this would seem to suggest that it's coming from something deep inside healthkit, since the error message is not localized.  in all reported cases, the user had recently upgraded to a new iphone.  in most cases, the problem only occurs on the new device even though everything had been working correctly prior to the upgrade.  the error occurs when the app is unable to read step count data from healthkit. we have confirmed that the app has been granted access permissions to all health data via os settings.  we've also tried having the user toggling those settings off, then back on, rebooting the device, deleting and reinstalling the app, etc., to no avail. the error message is "Unable to invalidate interval: no data source avallable." we'd appreciate it if anyone can shed more light on this issue. thanks!

We have implemented Universal Links for iOS. We have deployed the following file as per the documentation: /.well-known/apple-app-site-association Everything works fine until my organization applied domain-level block on traffic out side my country. We need to whitelist Apple servers but we cannot find their IPs or domains used to access this file.

This issue has cropped up many times here on DevForums. Someone recently opened a DTS tech support incident about it, and I used that as an opportunity to post a definitive response here. If you have questions or comments about this, start a new thread and tag it with Network so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" iOS Network Signal Strength The iOS SDK has no general-purpose API that returns Wi-Fi or cellular signal strength in real time. Given that this has been the case for more than 10 years, it’s safe to assume that it’s not an accidental omission but a deliberate design choice. For information about the Wi-Fi APIs that are available on iOS, see TN3111 iOS Wi-Fi API overview. Network performance Most folks who ask about this are trying to use the signal strength to estimate network performance. This is a technique that I specifically recommend against. That’s because it produces both false positives and false negatives: The network signal might be weak and yet your app has excellent connectivity. For example, an iOS device on stage at WWDC might have terrible WWAN and Wi-Fi signal but that doesn’t matter because it’s connected to the Ethernet. The network signal might be strong and yet your app has very poor connectivity. For example, if you’re on a train, Wi-Fi signal might be strong in each carriage but the overall connection to the Internet is poor because it’s provided by a single over-stretched WWAN. The only good way to determine whether connectivity is good is to run a network request and see how it performs. If you’re issuing a lot of requests, use the performance of those requests to build a running estimate of how well the network is doing. Indeed, Apple practices what we preach here: This is exactly how HTTP Live Streaming works. Remember that network performance can change from moment to moment. The user’s train might enter or leave a tunnel, the user might step into a lift, and so on. If you build code to estimate the network performance, make sure it reacts to such changes. Keeping all of the above in mind, iOS 26 beta has two new APIs related to this issue: Network framework now offers a linkQuality property. See this post for my take on how to use this effectively. The WirelessInsights framework can notify you of anticipated WWAN condition changes. But what about this code I found on the ’net? Over the years various folks have used various unsupported techniques to get around this limitation. If you find code on the ’net that, say, uses KVC to read undocumented properties, or grovels through system logs, or walks the view hierarchy of the status bar, don’t use it. Such techniques are unsupported and, assuming they haven’t broken yet, are likely to break in the future. But what about Hotspot Helper? Hotspot Helper does have an API to read Wi-Fi signal strength, namely, the signalStrength property. However, this is not a general-purpose API. Like the rest of Hotspot Helper, this is tied to the specific use case for which it was designed. This value only updates in real time for networks that your hotspot helper is managing, as indicated by the isChosenHelper property. But what about MetricKit? MetricKit is so cool. Amongst other things, it supports the MXCellularConditionMetric payload, which holds a summary of the cellular conditions while your app was running. However, this is not a real-time signal strength value. But what if I’m working for a carrier? This post is about APIs in the iOS SDK. If you’re working for a carrier, discuss your requirements with your carrier’s contact at Apple. Revision History 2025-07-02 Updated to cover new features in the iOS 16 beta. Made other minor editorial changes. 2022-12-01 First posted.

I'm trying to implement a virtual serial port driver for my ham radio projects which require emulating some serial port devices and I need to have a "backend" to translate the commands received by the virtual serial port into some network-based communications. I think the best way to do that is to subclass IOUserSerial? Based on the available docs on this class (https://developer.apple.com/documentation/serialdriverkit/iouserserial), I've done the basic implementation below. When the driver gets loaded, I can see sth like tty.serial-1000008DD in /dev and I can use picocom to do I/O on the virtual serial port. And I see TxDataAvailable() gets called every time I type a character in picocom. The problems are however, firstly, when TxDataAvailable() is called, the TX buffer is all-zero so although the driver knows there is some incoming data received from picocom, it cannot actually see the data in neither Tx/Rx buffers. Secondly, I couldn't figure out how to notify the system that there are data available for sending back to picocom. I call RxDataAvailable(), but nothing appears on picocom, and RxFreeSpaceAvailable() never gets called back. So I think I must be doing something wrong somewhere. Really appreciate it if anyone could point out how should I fix it, many thanks!

Hello. I took a closer look at the data I'm getting back for hourly forecasts and I'm baffled by results I'm seeing. For example, it's Dec 19, 2022 8:00am PT and I'm asking for the weather for Orchard Park NY (lat 42.766437 long -78.743855) for Dec 23, 2022. The daily forecast tells me they're expected to have 5.9" of snow. However, the hourly forecast with the most snow that day is reported as 0.071" (1.8mm). The Apple Weather app on iOS shows that hour as having 0.6". I wrote a 'for' loop to print the results of my call to WeatherService.shared.weather.         print(oneHour.precipitationAmount.formatted())         print(oneHour.precipitationAmount.description)         print(oneHour.precipitationAmount.unit)         print(oneHour.precipitationAmount.value) 0.071 in 1.8 mm <_NSStatic_NSUnitLength: 0x2010b0178> mm 1.8

I'm using the iOS simulator with a StoreKit configuration file. I can see that there have been transactions while the app has been closed, but my StoreKit 2 listener is never called with those updates to be able to finish them When I open my app from a cold start. I've added a listener on application(_:didFinishLaunching:launchOptions:) like this: func startObservingTransactions() { task = Task(priority: .background) { for await result in Transaction.updates { if case .verified(let transaction) = result { await transaction.finish() } } } } But the Transaction.updates loop never gets called (have added breakpoints to check). It's only ever called when a purchase is made, or subsequent transaction renewals when the app is open. Only then it will get the previously unfinished transactions. Steps to reproduce: Create an app with a StoreKit config file (with sped up transactions) to purchase an item Make a purchase then quit the app Wait for a bit for more transactions to be made while the app is closed. Open the app from a cold start and none of the transactions will be finished by the listener in your app. Cancel the subscription via the transaction manager. Close and open the app from a cold start. The first transaction will be finished by the listener but none of the others will be. In Apple's docs it says If your app has unfinished transactions, the listener receives them immediately after the app launches Why is this not the case?

I can build the SimpleFirewall application (https://developer.apple.com/documentation/networkextension/filtering_network_traffic ) using xcode: After I run the application, seems can't block any traffic. I find there is some logs from network extension process: networkd_settings_read_from_file Sandbox is preventing this process from reading networkd settings file at "/Library/Preferences/com.apple.networkd.plist", please add an exception. Any step I am missing ?

I'm struggling to understand why the async-await version of URLSession download task APIs do not call the delegate functions, whereas the old non-async version that returns a reference to the download task works just fine. Here is my sample code: class DownloadDelegate: NSObject, URLSessionDownloadDelegate { func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didWriteData bytesWritten: Int64, totalBytesWritten: Int64, totalBytesExpectedToWrite: Int64) { // This only prints the percentage of the download progress. let calculatedProgress = Float(totalBytesWritten) / Float(totalBytesExpectedToWrite) let formatter = NumberFormatter() formatter.numberStyle = .percent print(formatter.string(from: NSNumber(value: calculatedProgress))!) } } // Here's the VC. final class DownloadsViewController: UIViewController { private let url = URL(string: "https://pixabay.com/get/g0b9fa2936ff6a5078ea607398665e8151fc0c10df7db5c093e543314b883755ecd43eda2b7b5178a7e613a35541be6486885fb4a55d0777ba949aedccc807d8c_1280.jpg")! private let delegate = DownloadDelegate() private lazy var session = URLSession(configuration: .default, delegate: delegate, delegateQueue: nil) // for the async-await version private var task: Task&lt;Void, Never&gt;? // for the old version private var downloadTask: URLSessionDownloadTask? override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) task?.cancel() task = nil task = Task { let (_, _) = try! await session.download(for: URLRequest(url: url)) self.task = nil } // If I uncomment this, the progress listener delegate function above is called. // downloadTask?.cancel() // downloadTask = nil // downloadTask = session.downloadTask(with: URLRequest(url: url)) // downloadTask?.resume() } } What am I missing here?

Hi, thanks for reading my question. I need help with some odd behaviour with product.purchase() not triggering a confirmation dialog after a subscription has expired and trying to purchase it again. Seeing this in iOS 16.2 and 15.7.2 (haven't tried any other versions) on actual devices, not in simulator. I'm using a sandbox user on the sandbox environment (not using the local store kit config file testing option). Using a newly created sandbox user, first subscription purchase goes through just fine, dialog box pops up, login with sandbox user, get confirmation of purchase and then Transaction.currentEntitlements has one item as expected. It auto renews for 12 times (each time Transaction.currentEntitlements contains the correct results) and then expires, as expected for sandbox. Transaction.currentEntitlements is then also empty, as expected. All good so far. Now I want to test purchasing it again...Call product.purchase() again to renew/start a new subscription and nothing happens, no confirm purchase dialog box pops up at all. The purchase function simply exits BUT returns success (as in the following gets called) but in self.updatePurchasedProducts(), Transaction.currentEntitlements is empty. case let .success(.verified(transaction)):      // Successful purchase       await transaction.finish()      await self.updatePurchasedProducts() if I instead go to Settings->App Store->Sandbox User-> Manage Subscriptions and renew the subscription there, instead of in my app, then Transaction.currentEntitlements has a new entry and all is good again. Alternatively, if I create yet another new sandbox user and logout of the old one I was using, I am once again able to purchase from within the app, so .purchase() once again works as normal. Is there something I am missing about expired subscriptions and trying to purchase them again in the app? Is this a sandbox issue and in production I'll have no problem? The sandbox user has purchasing enabled in Settings->App Store. I've also tried calling AppStore.sync() (which is in my "Restore Purchase" button) before calling product.purchase() after the subscription stops renewing, expires and this issue comes up, doesn't resolve it. Also have a less important question, the initial call to product.purchase(), the one that works as expected, has a bit of a delay before the confirmation dialog pops up, a few seconds, which will probably result in the user clicking the buy button again thinking it didn't work. Is a bit of a delay normal for sandbox? Will it be ok in production? When it fails, and I have to renew in Settings->AppStore->Sandbox user, there's also a bit of a delay after I return to my app, 5-15 or so seconds, before the transaction observer fires and currentEntitlements is checked again, is there a way to reduce this delay? Thank you!

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 with a single DeviceActivityReport, I run into inconsistencies where the View provided by the extension takes multiple seconds to load or fails to load altogether. The behavior seems random...I will build the application with the same code multiple times and see different behavior each time. Finally, a plug for better support in the Simulator for the entire set of Screen Time APIs. Thanks!

Hi guys, I'm trying to upload my app with Tap to Pay on iPhone functionality. However, I'm getting error message "Profile doesn't include com.apple.developer.proximity-reader.payment.acceptance entitlement." I've confirmed many times that I have the distribution profile with this capability. Any idea what might be the issue? The development environment works perfectly.

I'm writing an app that uses text to speech. On the physical Iphone 12 it works but on the simulator I don't get any speech from my app. I tried the following to enable. Settings -> Accessebility -> "Spoken Content" -> "Speak Selecton" to ON (green) in Voices I added the German Anna that I use on my Iphone with the downloaded enhancements. The speech test works in this menu but not in my app. What am I missing ? Cheers, Gerhard
