There are 2 textfileds. When focus switches between these 2 fields, On iOS18: it will call the keyboardWillShowNotification On iOS26, it will NOT call this keyboardWillShowNotification. Is it a bug or a feature?

https://developer.apple.com/documentation/callkit/preparing-your-app-to-be-the-default-calling-app I have 2 accounts, one for App store and one for tesing (Inhouse type). I added the capability in the Xcode project, and can run it. But when I run a Inhouse build for it on my CI server, it failed. So is the Inhouse build support this "com.apple.developer.calling-app"?

My app support ringout feature, when set Ringout, all the calls in my app will go to native, by using tel://xxx. But when my app set as the default calling app by the user. Then when user make a call from Contact, it will jump to my app, but app will will route this call to native. So there is a issue for this, then the quesion is: How to check if my app is set as default calling app?

I found this api may fail after iOS18.0 open func request(_ transaction: CXTransaction, completion: @escaping ((any Error)?) -> Void) But I can not reproduce it and it will recover after relaunch the app. Is there any issue for this or guide line after iOS18?

I have an audio issue on iPhone 15 Pro (iOS18.5). After some steps, the new call will be on one-way audio status, but tap mute and unmute will back to normal. See the attached video and check the "yellow dot indicator" for the audio status. Video link: https://youtube.com/shorts/DqYIIIqtMKI?feature=share I have a similar issue on iOS15 and iOS16, and no issue on iOS17, but now I have this issue on iOS18 with dynamic island model devices. Please check. Thanks.

Before iOS16, we can use https://developer.apple.com/documentation/coretelephony/ctcarrier But after iOS this is deprecated and has no replacement. There are some discussions on it, eg. https://developer.apple.com/forums/thread/714876 https://developer.apple.com/forums/thread/770400 Now I asked AI, then it provided this solution, to check the serviceCurrentRadioAccessTechnology, so it this ok to check the SIM card status? var hasSIMCard = false let info = CTTelephonyNetworkInfo() if let rat = info.serviceCurrentRadioAccessTechnology, rat.values.contains(where: { !$0.isEmpty }) { hasSIMCard = true. // has RAT } BTW, I can see a lot of changes in the Core Telephony framework. https://developer.apple.com/documentation/coretelephony 1.isSIMInserted https://developer.apple.com/documentation/coretelephony/ctsubscriber/issiminserted A Boolean property that indicates whether a SIM is present. iOS 18.0+ iPadOS 18.0+ This value property is true if the system finds a SIM matching the Info.plist carrier information (MCC / MNC / GID1 / GID2). Is this ok to check SIM insert status, this seems must preconfig some info in the info.plist. 2.iOS26 provide CTCellularPlanStatus https://developer.apple.com/documentation/coretelephony/ctcellularplanstatus Can I use this to check SIM status?

Steps to Reproduce make an outbound call cover the sensor Actual Behavior the screen won't go dark device iOS Result iphone15 17 Pass iphone14p 18.0.1 Pass iphoneXs_pro max 18.1.1 Pass iphone13pro max 18.2.1 Pass iphone16pro 18.2 Fail iphone15pro max 18.3 Fail iphone12 pro max 18.3 Fail ps: Skype has the same probelm Seems like this issue only happens on iOS18.2+ on some devices, so is there a bug for this?

I read this doc and find some key info. https://developer.apple.com/carplay/documentation/CarPlay-App-Programming-Guide.pdf CarPlay app entitlements All CarPlay apps require a CarPlay app entitlement that matches your app type. To request a CarPlay app entitlement, go to http://developer.apple.com/carplay and provide information about your app, including the type of entitlement that you are requesting. You also need to agree to the CarPlay Entitlement Addendum. Apple will review your request. If your app meets the criteria for a CarPlay app, Apple will assign a CarPlay app entitlement to your Apple Developer account and notify you. But I still have questions about the old and new CarPlay. // About account permission I have 2 Apple developer accounts. Account A (normal dev account): Here our app already supports the old-style CarPlay UI. (before iOS14) And I can see there are "CarPlay Messaging App" and "CarPlay VoIP Calling App" in the "Additional Capabilities" tab in my Identifier. Account B (Enterprise account): I can see there is a "CarPlay Communication App" in the "Additional Capabilities" tab in my Identifier. But I don't know (or don't remember) if I have requested this new CarPlay entitlement for this account. Quesiton 1: If I want to refactor my current CarPlay app (from old UI to new UI [iOS14 support]), Do I need to request the CarPlay entitlement for Account A? Because I can not find the "CarPlay Communication App" in Account A portal(or via Xcode). // About New CarPlay UI In the old UI, there are just 2 buttons showing after user tap the App icon now. One is for message and the other one is for VoIP call. But I can see only one VoIP call button in the new CarPlay UI, no seperated message button. Question2: Can I add a message button? If no, how to implement a similiar user experience. Thanks.

The app will be wake up from killed status by silent notification or not? This is a question for years, from my test. It will wake up. Here the wake up means it will call the "didFinishLaunchingWithOptions" method. But we can not see the app in the "recent apps" list after switching home-screen up. So any Apple dev can give me a detailed explain for this?

My VoIP app is installed on an iPad, but can't accept incoming calls by VoIP push. But it works after I force-restart this iPad. I have some customers who encountered the same cases, fixed by force-restart too. So my question is What happened on the APNs connection after force-restart? At what case, the APNs connection will be off?

(Put AirPods in the case.) BTW, if I tap the "Manual" button once I disconnected the BT, it also prints the "wrong" value for "availableInputs", and it will become normal after about 3~4 seconds.

Case-ID: 10075936 PLATFORM AND VERSION iOS Development environment: Xcode Xcode15, macOS macOS 14.5 Run-time configuration: iOS iOS18.0.1 DESCRIPTION OF PROBLEM Our customer experienced an one-way audio issue when switching from the built-in microphone to AirPods Pro (model: A2084, version: 6F21) during a VoIP call. The issue occurred when the customer's voice could not be heard by the other party, but the customer could hear the other party's voice. STEPS TO REPRODUCE Here are the details: After the issue occurred, subsequent VoIP calls experienced the same issue when using AirPods Pro, but the issue did not occur when using the built-in microphone. The issue could only be resolved by restarting the system, and killing the app did not work. Log and code analysis: In WebRTC, it listens for AVAudioSessionRouteChangeNotification. In the above scenario, when webrtc receives the route change notification, it will print the audio session configuration information. At this point, the input channel count was 0, which was abnormal: [Webrtc] (RTCLogging.mm:33): (audio_device_ios.mm:535 HandleValidRouteChange): RTC_OBJC_TYPE(RTCAudioSession): { category: AVAudioSessionCategoryPlayAndRecord categoryOptions: 128 mode: AVAudioSessionModeVoiceChat isActive: 1 sampleRate: 48000.00 IOBufferDuration: 0.020000 outputNumberOfChannels: 2 inputNumberOfChannels: 0 outputLatency: 0.021500 inputLatency: 0.005000 outputVolume: 0.600000 isPreferredSpeaker: 0 isCallkit: 0 } If app tries to call API, setPreferredInputNumberOfChannels at this point, it will fail with an error code of -50: setConfiguration:active:shouldSetActive:error:]): Failed to set preferred input number of channels(1): The operation couldn’t be completed. (OSStatus error -50.) Our questions: When AVAudioSession is active, the category and mode are as expected. Why is the input channel count 0? Assuming that the AVAudioSession state is abnormal at this point, why does killing the app not resolve the issue, and why does the system need to be restarted to resolve the issue? Is it possible that the category and mode of the AVAudioSession fetched by the app is currently wrong? Does it need to be reset again each time the callkit is started if the category and mode fetched are the same as the values to be set?

I have an app that was transferred from another account, but now the notifications are not working with the account's Team ID, Key ID, and .p8 file. Here are the details: On 9/14, the app was transferred to my RingCentral account. We tested the notification features, and everything worked well (both VoIP and normal push notifications). At that time, the server was still using the old Team ID, Key ID, and .p8 file configuration. On 9/24, we noticed that the notification features had stopped working. We then switched to using RingCentral's Team ID, Key ID, and .p8 file, and the notifications started working again. This raises some questions about the app transfer and notification configuration process: 3.1 After an app is transferred, do we need to immediately switch to the new account’s configuration (in this case, the RingCentral account: Team ID, Key ID, and .p8 file)? 3.2 How long does the old configuration (ld account) remain valid for notifications after an app is transferred (in this case, the Unify Office app: Team ID, Key ID, and .p8 file)? Thanks in advance for your help!
