CallKit is not get updated on iPhone 14 with Dynamic Island When I am receiving incoming call I need to update localizedCallerName in CallKit. As of iOS 17.2, localizedCallerName does not change. Is there anything I need to specify to update the name? Looks like the problem is related to CXCallUpdate() This is the code I use for updating caller name: func updateCallerName(_ call: Call) { let update = CXCallUpdate() update.localizedCallerName = call.localizedCallerName cxProvider.reportCall(with: call.uuid, updated: update) }

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread. I have been experiencing frequent crashes on iOS 17 and above recently, and I'm having trouble pinpointing the source of the crashes. The crash logs provide no information about the specific location of the crashes. Is there any workaround or solution to identify and resolve this issue? Please find attached the crash logs below

0 I am building a simple macOS menu bar app in swift that displays my machine's CPU temperature and I'm just testing out my function to make sure it can retrieve the temp and display it in the Xcode terminal but instead my error handler messages are triggered indicating an issue retrieving my machines CPU temp data "CPU temp °F could not be retrieved temps couldnot be displayed" import Cocoa import IOKit import IOKit.ps class CPUTempWithServiceMatching { static func getCPUTemp() -> Double? { let dictionaryMatching = IOServiceMatching("AppleSMC") var service = IOServiceGetMatchingService(kIOMainPortDefault, dictionaryMatching) var temp = "0.0" if service != 0 { let key = "TC0P" //thermal zone zero proxy if let result = IORegistryEntryCreateCFProperty(service, key as CFString, kCFAllocatorDefault, 0 ) { temp = (result.takeUnretainedValue() as!

Hi, I'm working in a MacOS Swift app that uses hdiutil and asr. Although I can send the sudo credentials and it can be read perfectly in the terminal, sometimes it appears that they are not enough to allow the program to run, throwing the following error: (asr) Failed to create source stream for replication Volume replication failed - Operation not permited This seems to be a permisions issue, because the very same code run perfectly when it is started from the terminal (szh). What would be the most practical way to overcome this issue? Any help will be highly appreciated.

A swift function name as getDataFromC which can connect with C function. A C function name as ExternalMethod which will receive the connect from swift. The parameter will be fill by call setData function. I can confirm that the entire structure return to getDataFromC was successful. Because I print the data of other structure members to check the correctness of the data. However, I don't know how to translate the largeData to [UInt8]. I try UnsafeMutableRawPointer type. I don't know what to do for the following action. I expected that output.largeData can be translate to [UInt8] type. //Bridging header file struct myStruct { void *largeData; int largeDataLength; int smallData[3]; } //C file void setData(myStruct* data) { int i = 0; uint8_t array[1024]; memset(array,0x66,1024); data->largeData = array; data->largeDataLength = 1024; data->smalData[0] = 0x99; data->smalData[0] = 0x88; data->smalData[0] = 0x77; } void ExternalMethod(myStruct* data) { setData(&output); } //Swift file func test() { var output = myStruct() getDataFromC(&output); var myPointer: UnsafeMutableRawPointer = output.largeData /* Here: I don't know how to translate data from myPointer to [UInt8] */ print("smallData: \(output.largeDataLength)") // 1024 transmission is correct print("smallData: \(output.smallData.0)") // 0x99 transmission is correct print("smallData: \(output.smallData.1)") // 0x88 transmission is correct print("smallData: \(output.smallData.2)") // 0x77 transmission is correct }

I have a swift callback function that accumulates data from the gyroscope handler CMGyroData to value, and takes care that it never goes below zero. Any thoughts why I got this crash? var value: Double = 90 func test(d: Double) { value -= d if value < 0 { value = 0 } else if value > 180 { value = 180 } // Double value cannot be converted to UInt8 because the result would be less than UInt8.min // according to Xcode, value is 0 let angle = UInt8(value.rounded()) print(angle) } During the crash, the debugger shows that value is 0, and the raw memory is 0x0000000000000000. I've heard about negative zero, but then the raw memory would be 0x8000000000000000. Either way, it makes no sense for the UInt8 constructor to fail. (lldb) p value (Double) 0 (lldb) p value.rounded() (Double) 0 (lldb) p UInt8(value.rounded()) (UInt8) 0 Xcode 15.1, iPhone 7 Plus, iOS 15.8 Edit: As a good measure, I changed that line to let angle = UInt8(Int(value.rounded()))

On macOS Sonoma I have a SwiftUI app that correctly plays remote video files and local video files from the app bundle. Where I'm having trouble is setting up the AVPlayer URL for a UVC camera device directly connected on the Mac. let url = URL(string: "https://some-remote-video.mp4")! player = AVPlayer(url: url) player.play() Is there some magic to using a UVC device with AVPlayer, or do I need to access the UVC device differently? Thanks, Grahm

Hi all, I'm trying to find the reason why my app is crashing and fix it. This is just happening in some devices and others are working fine. I have no idea how to do it and any hint on what to do will be really appreciated. I am in a test stage using testFlight and I am using crashlytics to collect the errors. The apps has Firebase services (Push Notification, firestore, crashlytics) google maps, Realm and more.

I'm creating an app with a video player streaming video from an URL. The AVPlayer only takes the URL address of the video but I'd like to create a custom URLRequest and then use that to stream the video from online. So current situation is this: let videourl = URL(string: "videofoobar.com") let player = AVPlayer(url: videourl) player.play() And I would like to go to something like this: let videourl = URL(string: "videofoobar.com") var request = URLRequest(url: videourl) let player = AVPlayer(request: request) //This obviously fails, any workaround? player.play() I know it is not possible to do it like this as AVPlayer only takes URL or AVPlayerItem as parameter. Is there any workaround to make URLRequest and then give it to AVPlayer for online streaming?

Hi folks, I'm trying to use a Transformer in a SwiftData class, but everytime i boot the app in the visionOS simulator it shows an error in main.

If I create a new project with the following code in main.swift and then Profile it in Instruments with the CPU Profiler template, nothing is logged in the Points of Interest category. I'm not sure if this is related to the recent macOS 14.2 update, but I'm running Xcode 15.1. import Foundation import OSLog let signposter = OSSignposter(subsystem: "hofstee.test", category: .pointsOfInterest) // os_signpost event #1 signposter.emitEvent("foo") // os_signpost event #2 signposter.withIntervalSignpost("bar") { print("Hello, World!") } If I change the template to the System Trace template and profile again, then the two os_signpost events show up as expected. This used to work before, and this is a completely clean Xcode project created from the macOS Command Line Tool template. I'm not sure what's going on and searching for answers hasn't been fruitful. Changing the Bundle ID doesn't have any effect either.

Hi, I'm currently looking for the exact criteria which sets NEHotspotNetwork.isSecure() value. I guess this boolean value depends on whether protocol &gt;= WPA2 or 3, but I'm not sure. I hope someone tell me. If possible, linking references would be a great help. Please help me.

Hi I was trying to design the above UI, But using the below code of CPListImageRowItem func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) { self.interfaceController = interfaceController // Create a list row item with images let item = CPListImageRowItem(text: "Category", images: [UIImage(named: "cover.jpeg")!, UIImage(named: "cover2.jpeg")!, UIImage(named: "discover.jpeg")!, UIImage(named: "thumbnail.jpeg")!]) // Create a list section let section = CPListSection(items: [item]) // Create a list template with the section let listTemplate = CPListTemplate(title: "Your Template Title", sections: [section]) // Set the template on the interface controller interfaceController.setRootTemplate(listTemplate, animated: true) } I was getting only header and below image items but detailed text under images are no way to set. can any one help me out of this

The following situation is given: In your code you have a PDFDocument object. This contains a PDF file with form fields that are filled with text. If you call the dataRepresentation() method on this PDFDocument object, you get back a data object: let myDocumentData: Data = pdfDocument.dataRepresentation()! If you now want to initialize a new PDFDocument object with this data object, the contents of the form fields are duplicated within the PDF. let newPDF: PDFDocument = PDFDocument(data: myDocumentData) If you now want to print the newPDF PDFDocument object by creating a new print job, you will get the following result: What you actually expect to see: You only see this behavior when you want to print or share the PDF. You won't see this behaviour inside a PDF View in your application. This behaviour only appears since iOS/iPadOS 17.2 Steps to reproduce: Get a PDF file with form fields, especially text fields fill out these text fields with text create a PDFDocument object with this PDF file call the dataRepresentation() method on this PDFDocument object and store the result in a new variable create a new PDFDocument object with the data object created in the previous step:PDFDocument(data: <data>) Print the new created PDFDocument within iOS/iPadOS 17.2 or share it for example via email I hope Apple will fix this bug soon!

Dear Developer Community, My app is saving handwritten notes, forms and images as annotations in PDF documents by using PDFKit. Since iPadOS 17.2, the content of the annotations within the annotation boundaries is scaled down when saving the annotated PDF file. I.e. the annotation boundaries remain unchanged, but the displayed annotation content shrinks and no longer fills the boundaries. This gets worse with every save operation and applies both to newly created annotations and to elements that were saved before iPadOS 17.2. This issue only occurred after updating to iPadOS 17.2. The same code on my test device with iPadOS 17.1 works perfectly. Does anybody have a similar issue and/or found a workaround to solve this problem? Thanks for any idea!

I am reluctant to admit that I only came to know that Swift provides a builtin documentation markup syntax just a few months ago. /** Test func Some description here. - Parameters: - b:Test - d: Test - f: Test - Returns: Bool */ func myMethod(a b:Int, c d:Int, e f:Int) -&gt; Bool { b &gt; d } It seems the markup is pretty simple and has only a few keywords. But, I want to read through the complete reference. Any useful pointers?

Is there any way to identify if the QLPreviewController is in markup mode? I have a custom QLPreviewController which is used to preview and edit images in my app. I need to identify when entering the markup mode and make some changes in the navigation bar based on this. But I could not find any variable or delegate methods to identify this. Any help will be appreciated.

How is it possible to remake the Dynamic Island music spectrum (visual EQ) animation on macOS? I see WhatsApp have a similar animation on voice calls. Is there a 3rd or native Apple library to make it? https://imgur.com/a/PKDkosC

I have a MacOS screenshot app that was created in 2014. I've recently updated some code and libraries and am having problems with the transfer of screenshot entablements to the new app. Basically, if a user had the old version of my app they would have to delete the old enablement start the new app and then re-enable the updated version of the app. Why is this happening? It's confusing because the user sees that my app is enabled but the enablement isn't working.
