Camera's settings at calibration time
Hi everyone, I am wondering under which settings the camera(s) were set by the time they were calibrated. For instance, one aspect that is easy to find is the reference resolution of the images taken when calibrating the intrinsics, this is by retrieving intrinsicMatrixReferenceDimensions. Making sure that the principal point is referenced to the by the time resolution used when the calibration was ongoing. However, recently I saw that there are focusing modes that potentially displace the lens' physical position. Settings like: AutoFocusRangeRestriction: none, near, far setFocusModeLocked: Locks the lens position at the specified value, and sets the focus mode to a locked state. My concern lies the impact this focusing lens displacements have on the intrinsic matrix parameters, if the lens is displaced, these parameters no longer describe the camera since the lens position has changed w.r.t. the lensPosition set when they were calibrated [0-1]. If my understanding is correct the AutoFocusRangeRestriction is just a range freedom the system is allowed to auto-focus and not a specific lens position. Conversely, the setFocusModeLocked does indeed fix the lensPosition to a certain value [0 - 1]. In simple words, what is the focus lensPosition the cameras were set when calibrating them for intrnisics?

Developer Program Billing
Hi, I did get the renew invoice in email but there was an additional charge the same day / time for $6.19 from Apple , seems like it is related but cannot find any invoice in email or anything other than a charge line on the credit card. Does anyone have any idea what this additional charge might be? Still waiting to hear back from Apple.

Overnightforecast data from weatherResponse.dailyForecast.forecast array object
Background: We are using Apple WeatherKit for an app to fetch future weather data specialty cloudCover and condition and pretipitationChance from the Overnightforecast data from weatherResponse.dailyForecast.forecast array object. Code Sample: On xcode on Swift and Swift UI using Apple WeatherKit task{ do{ let weatherResponse= try await self.weatherService.forecast(for: latLong) let cloudCover = weatherResponse.dailyForecast.forecast[0].overnightforecast.cloudCover Issue: While we are on debug mode, we can literally see overnightforecast.cloudCover data (as well as condition and pretipitationChance) is available under from index 0 to index 10 of weatherResponse.dailyForecast.forecast array object but when we are trying to assign this property, its throwing error as "overnightforecast object not present under weatherResponse.dailyForecast.forecast array object" Attachment:

Issue Wifi Calling - with 5G and LTE - iOS Beta 18.4. 3rd beta and before
when I receive calls on my mobile number and I am connected to a Wifi, the calls is cancelled after the second ring and the caller receives a busy signal. That means I cannot receive calls anymore. This problems happens with different mobile providers and does not occur on my Samsung Galaxy Phone with the same number (eSim). Even when I disable WIFI Calling the problem persists, when I am connected to a WIFI. Only when I disable the WIFI Connect and I am only connected to the mobile carrier, the calls go throuhg in a normal way. VERY annoying and hast not been fixed with Beta 3 of iOS 18.4. Any clue how this can be solved with settings? Hope Apple fixes this very soon!

App development agency bankruptcy, what about our apps?
First, I apologize if I post to the wrong forum, but this is kinda new to me. Backstory: I recently joined a company as CTO and the first topic on my agenda is the mobile presence. The android app was built in-house, but the iOS app was outsourced to an app/web development agency. The problem: the aforementioned agency ceased operations in mid-2024 without notifying us. They cancelled their dev program enrollment and our apps are no longer available on the App Store. And the agency reps are not responding to emails and phone calls. My question: is there a way to get access to our application? We plan in-house redesign and refactoring in 2025, but we want access to the bundle ID, the app groups, the iCloud container, etc. We can present legal documents, company website and branding, everything to prove that app is technically ours. Thanks in advance! Have a good and productive 2025!

Turning on setVoiceProcessingEnabled bumps channel count to 5
Hi all, The use of setVoiceProcessingEnabled increases the channel count of my microphone audio from 1 to 5. This has downstream effects, because when I use AVAudioConverter to convert between PCM buffer types the output buffer contains only silence. Here is a reproduction showing the channel growth from 1 to 5: let avAudioEngine: AVAudioEngine = AVAudioEngine() let inputNode = avAudioEngine.inputNode print(inputNode.inputFormat(forBus: 0)) // Prints <AVAudioFormat 0x600002f7ada0: 1 ch, 48000 Hz, Float32> do { try inputNode.setVoiceProcessingEnabled(true) } catch { print("Could not enable voice processing \(error)") return } print(inputNode.inputFormat(forBus: 0)) // Prints <AVAudioFormat 0x600002f7b020: 5 ch, 44100 Hz, Float32, deinterleaved> If it helps, the reason I'm using setVoiceProcessingEnabled because I don't want the mic to pick up output from the speakers. Per wwdc When enabled, extra signal processing is applied on the incoming audio, and any audio that is coming from the device is taken Here is my conversion logic from the input PCM format (which in the case above is 5ch, 44.1kHZ, Float 32, deinterleaved) to the target format PCM16 with a single channel: let outputFormat = AVAudioFormat( commonFormat: .pcmFormatInt16, sampleRate: inputPCMFormat.sampleRate, channels: 1, interleaved: false ) guard let converter = AVAudioConverter( from: inputPCMFormat, to: outputFormat) else { fatalError("Demonstration") } let newLength = AVAudioFrameCount(outputFormat.sampleRate * 2.0) guard let outputBuffer = AVAudioPCMBuffer( pcmFormat: outputFormat, frameCapacity: newLength) else { fatalError("Demonstration") } outputBuffer.frameLength = newLength try! converter.convert(to: outputBuffer, from: inputBuffer) // Use the PCM16 outputBuffer The outputBuffer contains only silence. But if I comment out inputNode.setVoiceProcessingEnabled(true) in the first snippet, the outputBuffer then plays exactly how I would expect it to. So I have two questions: Why does setVoiceProcessingEnabled increase the channel count to 5? How should I convert the resulting format to a single channel PCM16 format? Thank you, Lou

Restart Issue iPhone 14 Pro Max
I have a iPhone 14 Pro Max device with iOS 18.2.1 but I am facing an in which the device gets restart abruptly.Interestingly, today the device is not restarting at all. I attempted a hard reset by pressing the volume up button, followed by the volume down button, and then holding the power button, but this method was unsuccessful. When I connect the device to a charger, the Apple logo appears, but it disappears after a short period, and the device does not progress beyond this point. I would appreciate any assistance in recovering my device.Has anyone experienced the same issue with the iPhone 14 series?

Error creating FileProvider domain on external drive
Hi, I am trying to use the new FileProvider feature available on macOS 15 to create a FileProvder domain on an external drive. I am creating the domain with the initializer init(displayName:, userInfo:, volumeURL:) But when I try to add the domain with NSFileProviderManager.add() I get error NSCocoaErrorDomain, code 3328 - feature not supported. My external drive is APFS formatted and encrypted. I am checking its eligibility with NSFileProviderManager.checkDomainsCanBeStoredOnVolume(at:) and the result is "eligible". What should be done to solve this problem - is there a specific entitlement I have to add? I checked the possible entitlements and I don't see anything pointing in this direction. I will be very grateful for any help!

A wired keyboard connected via a hub cannot wake up the iPad on iOS version after 18.0
Problem Description: On the iPad 10th tablet, when a USB 2.0 interface extended by a Type - C interface through a USB 2.0 hub is used to connect a keyboard, there is an issue that the keyboard cannot wake up the system when the system version is 18.0 (inclusive) or higher. However, this problem does not occur on systems earlier than 18.0. Note: To ensure low power consumption of the product, if there is no key press on the keyboard for 10 minutes, the power supply of some functions of the hub will be cut off, but the power supply of the keyboard will remain on. When a key is pressed, the power supply of all functions of the hub will be reconnected.

XCode and Running On iPad Hardware Instead of Simulator
Last year's submission form says that if you select (Run on Xcode) the app will be in the simulator not on an iPad. Has that changed this year, as I don't see it in the terms? (My app has imported local package dependencies for Reality Composer Pro that I am not certain would work on playgrounds for iOS. And it needs the iPad camera for AR functionality.)

Sequoia 15.3 Beta 24D5034f
Hi folks, First - I'm not a developer. Some time ago I came across Sequoia Beta and installed it thinking it was just a usage data collection thing. I recently wanted to delete it because I suspected it was causing other issues, but was only offered to have updates stopped. My MacBook Pro M2 still says I'm running Sequoia 15.3 (Beta 24D5034f). I have another, maybe unrelated issue and posted a question about it on Apple Community but the question was deleted and I was pointed here because I mentioned the Beta! This was my question: I can FaceTime from the iPhone but when I try to FaceTime from the Mac, I get a notification on the Mac saying: "iPhone calls not available. Your iPhone is not configured to allow calls using this Mac". My iPhone is a 14Plus on iOS 18.2.1 (22C161). I've tried the iPhone and Mac fixes suggested by Apple but no luck there - that was all about turning iMessages and FaceTime off or signing out for both devices, then power cycling both devices. I don't understand how this is supposed to work. Could my issue be related to the Beta? If so, and in any case, how do I remove the Beta? TIA
