We have been successfully using the PTT (Push-to-Talk) framework in our application since the release of iOS 17. Audio is recorded by pressing a PTT button and speaking after the PTT framework initiates an AVAudioSession. While the PTT framework has generally worked well since the iOS 17 release, we have received reports that, on occasion, after the app has been idle for a while ( when I have seen it my phone has been in flightmode over night), it suddenly records only silent audio. This issue does not occur every time but sporadically. For users experiencing this problem, pressing the PTT button results in no “PTT framework start sound,” and only “empty sound” is recorded. The only solution to restore audio is restarting the device. Restarting the app alone is insufficient, though leaving the PTT channel and rejoining it also resolves the issue. I have reproduced the problem several times and observed that everything appears normal within the app. We receive an active AVAudioSession from the PTT framework, a

Hello Dev team, 3 weeks I'm looking for how I can export a static Cinema 4D objects WITH TEXTURES to Reality Composer Pro ! I can export it directly on USDA format and it works well for the 3D model in Reality Composer Pro, BUT, I can't have the textures on my model. My model is simple not colored ! Of course I expect to have textures applied on the good place and same appearance I've in Cinema 4D. Could you give me a process to do that please ? I'm using Cinema 4D R25 and Last XCode and Reality Composer Pro beta versions. Big big thanks to the one could help me on this. It will unblock many things to me!!!! Cheers Mathis

I am working on a live activity with a button that will do a network call when pressed on. I want to make sure that it can only be pressed once, and then ignored while the request is processed. This is what I did: Since it seems that a new intent object is created for each button press, I am using a static synchroniser like this: private var _isBusy: Bool = false private var _timestamp: Date? = nil private let queue: DispatchQueue private let resetInterval: TimeInterval init(resetInterval: TimeInterval = 60, queueLabel: String = default.synchronizedBoolQueue) { self.resetInterval = resetInterval self.queue = DispatchQueue(label: queueLabel) } var isBusy: Bool { get { return queue.sync { return _isBusy } } set { queue.sync { _isBusy = newValue } } } func setIfNotBusy() -> Bool { return queue.sync { let now = Date() if let timestamp = _timestamp { if now.timeIntervalSince(timestamp) > resetInterval { // Reset if it was more than the specified interval ago _isBusy = false _timestamp = nil } } if !_isBusy {

One of our customer has reported that pushes are delivered with big delay. Pushes are send to APNS in less than 5 seconds as per our statistics but it takes sometimes up to 5 minutes for notifications to arrive on devices. The authentication used is certificate based even though token based authentications is also tried out before. They have around 346252 subscribed device tokens (users) to which important pushes are send out. We use HTTP/2 based connections and reuses the connections. To avoid push bursts over selective connection, we distribute push traffic across different APNs servers. Sample headers: [:method: POST, :authority: api.push.apple.com, :path: /3/device/, :scheme: https, apns-expiration: 1723721057, apns-priority: 10, apns-topic: , authorization: bearer ] Sample payload: {reference:{id:lux.DvKH5JCtCcus5EaW5Houcn,type:articleReference},aps:{badge:0,alert:{body:„Warum werden nicht ein paar gesetzliche Feiertage gestrichen?“ Munich-Re-Chef Joachim Wenning fordert, dass die Deutschen mehr

Hi. I display buildings in mixed immersive view. Right now the building appears in relation to the person when the view is opened. (world anchor) To position the building precisely, I want to use object tracking. Set up a project following the wwdc object tracking session. That works well sort of... With an object anchor, the 3D object related to the anchor disappears as soon as the Tracked object is out of view, and with the big objects you don't get the chance to look around. I figure I need to give my 3D object a world anchor, and only have that world anchor update if a change in the object anchor is detected. how do I do that? Preferable using the tools in Reality Composer pro (or very well explained, as I am new to code)

hello. I installed ios 18 beta from the official website, but I had a big problem after the update. The storage began to fill up abruptly with the system date, 30GB was free, it became 1-3 GB. how to fix it?

For the past few days my imessage has been acting strangely, if I send a line of messages only the first few will say they had a problem sending. At first I chalked it up to my wifi messing up but even after switching locations/using data instead it still randomly shows messages as not sending. Then on top of that my phone will send notifications twice from all my apps, for example I got a message on discord and the notifcation sent twice. And a similar issue to the notification thing is that even if I’ve already read a notif/replied to it it’ll come up a minute later as if I hadn’t already seen it and clicked it. None of them are that big of an issue but it becomes aggravating after a while. I’ve reset my phone, updated it, and cleared up my storage and nothing seems to work. I’m not even sure how to classify what I’m going through. Any tips on how to fix this?

I'm writing software that uses the security framework to get signing information from applications. I noticed that over time memory consumption goes up. After checking with Instruments, I saw an accumulation of objects coming from the internals of the security framework. These allocated objects don't seem to go away. Following is a standalone code sample that seems to cause the problem in my env. Running it by itself creates a big number of objects that are not released. I also attached a screenshot from Instruments. #include #include #include OSStatus get_signing_info(const char* path) { SecStaticCodeRef codeRef = NULL; OSStatus status; NSString* str = [NSString stringWithUTF8String:path]; NSURL* url = [NSURL fileURLWithPath:str]; status = SecStaticCodeCreateWithPath((__bridge CFURLRef)url, kSecCSDefaultFlags, &codeRef); CFDictionaryRef _info = NULL; status = SecCodeCopySigningInformation(codeRef, kSecCSSigningInformation, &_info); NSDictionary* info = (__bridge_transfer NSDictionary *)_i
