Troubleshooting Video Loading Issues on iOS: Slow Performance Over Mobile Data but Fast on Wi-Fi
Hello, We are developing a social media application that allows users to share and view content in the form of images and videos. The app is built with Angular and Ionic, and we use Capacitor to integrate native functionalities. Currently, we are experiencing an issue with content loading on iOS devices. Specifically, when the iPhone is connected to Wi-Fi, videos load quickly and play smoothly. However, when using mobile data, videos take a long time to load or, in some cases, do not load at all. We are trying to identify the cause of the issue and determine whether it could be related to Xcode configuration or any system restrictions. Some potential reasons we have considered include: iOS Mobile Data Usage Restrictions iOS may limit mobile data usage for large downloads or streaming content if the app does not have the proper permissions. In Settings > Mobile Data, users can restrict data usage for specific apps. App Transport Security (ATS) Configuration Xcode and iOS enforce strict security policies for network connections through App Transport Security (ATS). If the API serving the videos uses HTTP instead of HTTPS or has restrictive headers, this could affect loading over mobile networks. Xcode Network Usage Settings Xcode allows configurations related to network access. There might be a setting limiting access to mobile networks when the device is not on Wi-Fi. Video Quality and Adaptability Differences If videos are not optimized for mobile networks (e.g., high-quality formats without adaptive versions), loading times could be significantly longer. Implementing HLS (HTTP Live Streaming) could improve playback on slower networks. Request Timeout Issues If video loading requests have a short timeout, slower mobile network connections might exceed this limit, causing the request to fail. Compression and Caching It is essential to check if videos are properly compressed and if caching is implemented to improve performance on mobile networks. Given this situation, we would like to know what Xcode settings might be affecting video loading performance on mobile data and how we can adjust them to enhance the user experience.

Developer Enrollment - Bug.
Hi everyone, We're hoping someone here can help us out. We've run into a consistent issue when trying to enroll a new Apple Developer account as an organisation using our DUNS number. Here's what we've experienced: Individual enrollment through the Developer app works perfectly with a new Apple ID. However, when using an existing Apple ID and selecting organization enrollment, the process gets stuck: The payment button is greyed out in the Developer app. We're then locked out of enrolling through the app entirely. 4. When trying to complete the enrollment via the Developer website, there’s no valid payment method available (e.g., VISA option missing CVV field), and any attempts to proceed just loop without success. We're essentially stuck in a limbo state where we can’t proceed. We’ve gone through all the support channels: The automated assistant (Gaby) is unable to resolve the issue or understand the full context. Live chat support for both individual and business accounts told us they can’t assist and referred us back to the developer support system—which leads us back to square one. All members of our team were able to enroll individually without issue, but organisation enrollment consistently failed. Business support and Commercial support (spoken to supervisors) are unable to assist. They really tried and made an effort. Has anyone experienced this before? Is there a way to get in touch with a real person at Apple who can actually resolve this? What are our next steps? Any advice would be greatly appreciated. Thanks!

I've been fooling around with this and I lose "stuff"
I have an idea for an app for awhile (5+ years) and it took awhile (a year or more to figure out how to develop on - I know C/C++/FORTRAN, started in the punch card era). I ended up using the MacBook I had, some books and chatGPT and plunged into development. BTW this was all happening while I'm retired, included moving to FL from MD. There are times where development stops for months at a time, I've started and stopped at least four or five times on different portions of the project. I've realized that I can actually skip the user interface until the end if ever. At the beginning of code development, I did little more that "Hello world" programs to get my feet wet. Golf, pickleball, doctor appointments, etc. interrupts development. When I get back to it, my code has "disappeared", I open Xcode, open the project and I don't see any of my code - where did it go? I did find the code using the Finder in Directory/projname/projname/ContentView.swift (I'm not sure why projname is duplicated, no doubt my ignorance!) - so the code is still present, somewhere!

Printing error
Back in December 2024 I noticed when I go through the steps to print I would get an error to cancel or retry. We have 4 iPhones and 3 had the newest IOS and those 3 would get the same error. The phone that had old ios 17 something the print would work. Called Apple and did troubleshooting, the opened something on apples end for the developer to investigate. Within 2 weeks a new ios was available and fixed the issue on the 3 phones that could not print. I did the latest update February and March 2025 on all 4 phones thinking no way the issue will happen again and if did all 4 phone cannot print. Is there an iOS bug that is affecting printing ios 18.3.2.

Plugin/Module deployment support in App Store
Our app provides configuration and maintenance features for Siemens electrical devices. The app supports multiple devices and the devices have their own specific features, which also need to be supported by our App. The devices can be released to the market only when our app supports those features. Our app release timeline is once in every 4 months. We face a challenge when some of these devices are not able to deliver their features by our release time. So, we would like to make these devices plugins, which can be independently released, without releasing the App every time. The app would, of course, be released once in every 4 months, depending on the common features. I'm not able to find how to release only the plugins within the app, without releasing the entire app. Some one has suggested app extensions, but that does not fit our solution as in some cases, we need continuous polling of data from one or mode devices for minutes or hours, as the app can be used by the user to monitor some of the device values.

CarPlay music sound output from iPhone after enabled Enhanced Siri
With CarPlay communication plugin R18.1, I followed these steps to integrate Enhance siri, the music sound was output from carplay and there is no option for output to Car. ============================================ Enhanced Siri Declare supported audioFormats for the AuxIn and AuxOut streams Since the AuxIn and AuxOut streams for Siri do not have to be both active at the same time, the accessory must claim audio formats support for AuxIn Audio and AuxOut audio independently. The audio formats for each stream can differ from each other (48KHz for AuxOut and 16KHz for AuxIn). The new audio types represent these new streams - AuxIn/speechRecognition & AuxOut/speechRecognition. Check if connected device supports the feature AirPlayReceiverSessionHasFeatureEnhancedSiri() Claim support in the Setup Response message if device supports the feature Add kAirPlayKeyAccessoryEnabledFeature_EnhancedSiri key through the AirPlayReceiverServer delegate AirPlayReceiverServerCopyProperty_f function for the kAirPlayKey_AccessoryEnabledFeatures key. Helper function: CFArrayAppendValue() Add Enhanced Siri parameters dictionary in the INFO message Add dictionary through the AirPlayReceiverServer delegate AirPlayReceiverServerCopyProperty_f function for the kAirPlayKey_EnhancedSiriInfo key. kAirPlayKey_EnhancedSiriInfo dictionary parameters: Voice activation of Siri - kAirPlayKey_EnhancedSiriVoice Current language of voice model - kAirPlayKey_VoiceModelCurrentLanguage Supported languages of voice model - kAirPlayKey_VoiceModelSupportedLanguages Enhanced Button activation of Siri - kAirPlayKey_EnhancedSiriButton Supported zone(s) if any - kAirPlayKey_SupportedSiriTriggerZones Update AudioStream Get state of the AuxIn state by providing an implementation of AudioStreamUpdateState() - Off, local buffering, or streaming to device. Decouple input streams from output streams. AuxIn is an independent input stream only. The property kAudioStreamProperty_Direction will provide the necessary information if the stream is input, output or input & output. Provide a handler for the AirPlayReceiverSessionDelegate setEnhancedSiriParams_f This will provide additional information: Activation type Setting the language of the voice model Invoke the Communication Plugin to start buffering Once the activation type has been specified, the accessory can request the plugin to start buffering using AirPlayReceiverSessionAuxInStart(). Use the new APIs to trigger Siri: AirPlayReceiverSessionRequestSiriActionWithLatency() AirPlayReceiverSessionRequestSiriVoiceActivationWithLatency() AirPlayReceiverSessionRequestSiriVoiceActivationWithSample() Button presses and voice activations should use this new APIs which adds a timestamp of the activation. These APIs allow a choice of a latency or a sample for button and voice activations. If there is a delay between the user pressing the button to notifying the device on the button press, this latency value should represent this time. If the accessory can determine which zone activated, it can provide the zone with the request. Invoke the Communication Plugin to stop buffering You may need to invoke the plugin to stop buffering (AirPlayReceiverSessionAuxInStop()) if exclusive access to the microphone is necessary. Such instances may include but not limited to: Native voice recognition session Telephony Another stream function which uses the microphone starts modesChanged notification can be used to determine if a resource is being used Note, if the session ends, the plugin will automatically stop buffering

Unwanted Communication error cut off, no report sent
Hi, I've been trying to debug an issue with my extension. I am able to register the extension on install of my app, can select it under Phone> SMS/Call Reporting. When I touch Report it brings up my view controller, with the sender and message details. I set let response = ILClassificationResponse(action: .reportJunk) I've added debug logs throughout my extension and everything looks good. Now when MobileSMS takes over, I see: default 23:15:09.837024-0400 MobileSMS response: extension: error 23:15:09.837328-0400 MobileSMS error reporting SMS response: default 23:15:09.837387-0400 MobileSMS Finished, invoking didCompleteClassificationRequest info 23:15:09.837487-0400 MobileSMS didCompleteClassificationRequest -- di I don't see what the error is, and that last log entry is cut off at "di". I've confirmed my info.plist, allowed domains, aasa, and my remote API is not touched. Any advice? Xcode 16.3 Testing on iPhone 16e iOS 18.4.1

Trouble Displaying Heart Rate Data Graph from Apple Watch in iOS App
Issue with Heart Rate Graph from Apple Watch in iOS App Hello Community! I hope everyone is doing well. I'm developing an iOS app that includes a feature to display a graph of the heart rate recorded during a route using the Apple Watch. Current Implementation I have successfully implemented data collection and transfer from the Apple Watch to the iPhone. The app's main UI correctly displays the user's real-time BPM. When the user stops the route, an analysis view is generated, showing speed and altitude (both work perfectly). Expected Behavior The user starts recording a route while monitoring heart rate. After tapping "Stop Route," an analysis view should display a heart rate graph along with speed and altitude data. Issue Encountered Despite multiple attempts, I have not been able to properly generate the heart rate graph. The only result I have achieved so far is a flat line with points representing the recorded BPM over time, instead of a proper graph. Request for Help If anyone has experience implementing a similar feature, I would appreciate any guidance on correcting my implementation. I can share: The file responsible for graph visualization. The file handling data processing after the user stops the route. Any help or suggestions would be greatly appreciated! Summary I'm trying to display a heart rate graph from Apple Watch data in my iOS app. While data collection and transfer work fine, the graph only shows a flat line instead of a proper visualization. Speed and altitude graphs work correctly. If anyone has experience with this, I’d love some guidance!

CarPlay Driving Task App Start/Stop NAvigation
Hi you all, I wrote an CarPlay Driving Task App that can start Navigation to a well defined target. This works as expected (navigation app is started to the destination), but sometime, for any important reason, my application receives updates about current destination. I should interrupt current navigation to current destination and update to the new destination. I'm not able to interrnupt/update. Have you any idea if this is possible? Thanls in advance!

Issue with Developer
I am a startup founder based in India. Recently the iOS developer we were working with left the company in some what acrimonious circumstances. Post his departure from the company, he has made it clear that he will try to cause damage to our iOS app to the extent that it starts to crash. Even though we have removed his access, as a non tech founder, I am not sure what ways he can edit or hamper our iOS app and what measures we can take to protect the same. Please advise us with steps for us to secure our code and ensure no one can edit the same or hamper our iOS app on the app store. Thank you

How to Get Incoming Call Notifications to Create a Phone App in iOS 18.2+?
I am trying to create a phone app that can receive incoming call notifications using CallKit, as described in Apple's CallKit documentation. Added the com.apple.developer.calling-app entitlement in my .entitlements file. Implemented CXProvider and set up the delegate methods (provider:perform: and providerDidReset). Added UIBackgroundModes with voip in Info.plist. Configured CXProviderConfiguration to support phone numbers. I expected to receive incoming call notifications when my app was set as the default calling app. However, I am not receiving any notifications when an incoming call arrives. How can I properly detect and handle incoming calls in my default calling app? Is there any additional configuration required for iOS 18.2+?
