This is the complete Playground code: import MapKit import SwiftUI import PlaygroundSupport struct AddressSearchView: View { @State private var region = MKCoordinateRegion( center: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194), span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01) ) var body: some View { VStack { Map(position: .constant(MapCameraPosition.region(region))) { } .frame(height: 300) } } } struct AddressSearchView_Previews: PreviewProvider { static var previews: some View { AddressSearchView() } } PlaygroundPage.current.setLiveView(AddressSearchView()) When I try to run this I get this in the debug console: error: Couldn't look up symbols: protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI Hint: The expression tried to call a function that is not present in the target, perhaps because it was optimized out by the compiler. the preview never shows up. If I use other SwiftUI components and not the map it works fine. What is happening? Playground target is Swift 6 macOS (iOS does the same). Xcode 16.2

I am at a loss as to why, since the latest update, that my preview pane is no longer working. May i have some assistance on the matter? Thank you in advance! 😀✌️

Hello, I recently updated my app, and in the Transporter app it said that the processing failed. This is the email I recieved: Please correct the following issues and upload a new binary to App Store Connect. ITMS-90048: This bundle is invalid - Your archive contains paths that are not allowed: [._Symbols] I couldn't find anything related to this in XCode or anywhere else on the internet. What did I do wrong? For context, I am developing using Expo and React Native.

I'm trying to evaluate if we can support AR navigation with MapKit. The feature is supposed to be available for users in US. I tried to run the sample on my iPhone: https://developer.apple.com/documentation/arkit/tracking-geographic-locations-in-ar?language=objc But I'm in a location that ARGeoTrackingConfiguration.checkAvailabilityWithCompletionHandler: always return false. I think ARGeoAnchor isn't supported in my location. I tried to use simulated locations by Adding a gpx file when launching the app. Enabling Xcode -> Debug -> Simulate Location -> New York, NY, US But the availability for ARGeoAnchor is still false. Is that possible for me to develop the ARGeoAnchor feature outside of the covered areas?

I want use Swift and objective-c both, I build bridge header ,but I got to errors. I can't fix them. Please help me. Thank you . ios iphone app.

I am working on an XCode project and I have some Swift functions within a helper functions file. This file has some functions declared that create 3 global variables. These global variables are then used in various views throughout the app. In the functions, there are print statements for when it catches an error. However, when I run the app and I get an error that stems from this file, there are no print statements. How can I have this print statements show up in the debug console?

My project is using Fastlane 2.226.0. After converted groups to folders on XCode 16, I got an error when executed below function in Fastfile: get_version_number(xcodeproj: "MyProject.xcodeproj", target: "MyProject") Below is the error message output after I ran fastlane: Unable to find XCode build setting: MARKETING_VERSION

My application is in flightTest mode. I received my first two crash reports in XCODE /Organizer. The context is well described, and I was able to isolate the locations where very serious errors occurred. My application is connected. I'm missing one piece of data in this crash report: the time of the crash. This will help me see what (in my case) static data was being read on the data server at that time. This will help me investigate. Is it possible to obtain this information?

I implemented the cloudkit function, where users can connect with each other. The problem is, that if User A is doing a friend request and User B is accepting the request. The friend entry is correct visible for User B but not for User A. I can see in cloud kit that after the accepted request, the friend connection is set up correctly, also with the correct userID, but it not showing up for User A (the one that send the request) It's in the public database. In this view you sign in using Apple Sign-In and create a specific user ID. Then you can access a global leaderboard to compare with all signed-in users. Additionaly, there’s a friend tab where you can search for and type in a specific user ID. The target user sees the friend request, can accept it, and then the accepted friend appears in their friend list. However, the original requester doesn’t see the connection after acceptance even though CloudKit shows the records Add comment. I've also tried to add a placeholder in for User A, that e.g he send the request and then has a placeholder where it says e.g pending request to User B. After User B accepted the request, the placeholder will go away and no friend connection is displayed, very strange.

I have been using Xcode 16.2 for a long time. I downloaded it from the developer site. I recently downloaded Xcode 16.3. I was offline on an airplane and I got an error authenticating my account. Since then, I have not been able to sign my apps. I was able to create a new app that worked but in my effort to resolve the problem, I deleted my account and now I cannot add it back. I was getting a "bad URL" error. Now I'm getting "Could not connect to the server." I sent an email to Apple Dev Support and they told me to download Xcode from the App Store. I did that and it gave me the same error. Is anyone else having this problem? If Apple Dev Support cannot resolve it, I don't know how I am going to.

If I install RealmSwift into an ios app using SPM, I have no problems. However if I install it into an ios framework, then when building there is this error: error: missing required modules: 'Realm.Private', 'Realm', 'Realm.Swift' I have discovered that if I change the import statement from: import RealmSwift to private import RealmSwift then doing that makes this build error goes away (but doing that isn't a feasible workaround as I would like to publicly export classes stored in Realm from the framework). There's no point in posting issues with Realm on their support board as its being deprecated and its tumble weeds on their forum. But I would be very interested in hearing from the Apple expects explanation or speculation on: why is importing the same framework via SPM into a framework xcode project resulting in different behavior then when importing it into an app? why would changing import to private import make the build error go away? TIA

If you have two video segments, one HDR and one SDR, next to one another in a composition, the SDR one appears dark, since its max luminance will be lower than the max luminance of the HDR clip. iMovie handles this well by (reverse) tone mapping the SDR content to make it look HDR in an HDR composition. This is what I want to achieve. I've looked into algorithms to do this, and the best that I can find is the conversion from RGB to YCbCr described in Table 4 of BT.2020, followed by conversion method A (Section 4.2, table 4) of BT.2446-1. I have these implemented in a Core Image kernel, available at this repo. The issue that I'm seeing is that the colors are still much too hot, and while there are frames that appear close to properly tone mapped, it doesn't come close to the accuracy of iMovie's approach. If someone is an expert in colorimetry, etc., I'd really appreciate a breakdown of what I'm doing wrong here. To be specific: Assuming non-constant luminance for the YCbCr conversion Using a Metal Core Image kernel for the actual tone mapping The video composition uses Core Image filters directly The video composition is using BT.2020 colorimetry and the PQ transfer function. Below is a comparison of two screenshots, one using an unaltered HDR asset, and the other using the same asset transcoded to SDR with QuickTime, and reverse tone mapped to HDR for playback. Is there something I'm missing?

I'm encountering an issue while trying to build my iOS app in Xcode for the simulator. Issue: Xcode Version: 15.x macOS Version: 14.x (Sonoma) Simulator: iPhone 16 Pro Error Message: Command ClangStatCache failed with a nonzero exit code Steps Taken: Cleaned build folder (Shift + Cmd + K) Deleted DerivedData (rm -rf ~/Library/Developer/Xcode/DerivedData) Updated Xcode and checked iOS SDK updates Disabled Clang Static Analyzer Cache None of these steps resolved the issue. Any help would be appreciated! Thanks in advance.

Hi everyone, I’m facing a major roadblock with my family location tracking app, and I need some advice or guidance from the community. Background Back in 2021, I implemented NSE filtering entitlement to send location-based notifications and retrieve the device's location in return (as suggested by Apple’s technical code support). Over time, I built my app around this entitlement, adding many features that depend on it. When Location Push Service Extension was introduced for iOS 15+, I adapted accordingly: NSE filtering was used for devices below iOS 15 Location Push Service Extension was used for iOS 15+ NSE filtering also played a crucial role in: ✅ Accepting/rejecting location-based notifications ✅ Checking device settings & location permissions (since location push won’t work without proper permissions) The Issue In November 2024, I created a new developer account to change my business entity. Since then, I’ve been requesting the NSE entitlement repeatedly for four months, but Apple keeps rejecting it. Meanwhile, they approved the Location Push Entitlement, but without NSE filtering, I’m forced to rewrite a huge part of my app’s core functionality. I’ve sent multiple emails explaining my use case, but I keep getting rejected without any clear explanation or workaround. My Ask Has anyone faced a similar issue with NSE entitlement? Are there any alternative approaches to achieve the same functionality? Any advice on how to escalate this to Apple or get proper feedback on why it's being rejected? I’ve invested years into this app, and a forced rewrite would take months. Any help, insights, or contacts who could assist would be greatly appreciated! Thanks in advance! 🙏

I have a iOS app using a gobind xcframework library. All went well when using Xcode 15.0 (15A240d), but failed on Xcode 16.2 (16C5032a). It’s confirmed the failure is from only Xcode version difference, all others like source code, lib binary, physical test iPhone all keeping the exact same. After digging, the root comes from golang os.Executable() call (https://pkg.go.dev/os#Executable), which is used in xcframework library. Using Xcode 15.0, os.Executable() returns “/var/containers/Bundle/Application/E80602C7-EFFB-4F1B-9FF8-FBA0E7E3DA76/Runner.app/Runner” as normal. But with Xcode 16.2, os.Executable() panic with err “cannot find executable path”. I’ve checked Xcode&SDK version change history, couldn’t find any clue like relevant permissions restrictions stuff. Could someone please share a hint? Thanks .

I've been using XCode for development in C++ for several years. Suddenly, today it started having the following problem: Any time I try to compile my code, (even if I just finished successfully compiling it), it spends several minutes running CLangStatCache. This is according to the result of "Perform Action... Build with Timing Summary". Furthermore, if I first delete the ".../DerivedData/SDKStatCaches.noindex" folder, the problem goes away and it compiles immediately. However, it creates a new folder with a 32 Mb file in it, and then has the same problem the next time unless I delete that folder again. I do not want to have to delete this file every time I compile my code. Is there some way to turn this off? What happened that is different today from any other day in the last several years? I did just download and install the latest System software update, including XCode... Did that break something?

Versions XCode version: 16.2 iOS version: 17.0 Background I am trying to generate a QR code inside the ActivityReportExtention which encoded the FamilyActivitySelection information. The code is roughly: Question Can I create Image inside the ActivityReportExtension? I cannot even render a simple image (not QR code) inside the extension. How can I debug inside the extension? Logs of the extension are not shown in the console. Code A function to generate QR Code import CoreImage import UIKit func generateQRCode(from string: String) -> UIImage? { let data = string.data(using: .ascii) guard let filter = CIFilter(name: "CIQRCodeGenerator") else { return nil } filter.setValue(data, forKey: "inputMessage") filter.setValue("Q", forKey: "inputCorrectionLevel") // Q for medium quality guard let outputImage = filter.outputImage else { return nil } // Scale the QR code image so it looks clear on screen let transform = CGAffineTransform(scaleX: 10, y: 10) let scaledImage = outputImage.transformed(by: transform) // Create a CIContext and generate a CGImage from the CIImage let context = CIContext() if let cgImage = context.createCGImage(scaledImage, from: scaledImage.extent) { return UIImage(cgImage: cgImage) } else { return nil } } Inside ActivityReportExtension sandbox: struct LineChartView: View { var body: some View { VStack { if let qrImage = generateQRCode2(from: "this is a test") { Image(uiImage: qrImage) .resizable() .scaledToFit() .frame(width: 200, height: 200) } else { Text("QR Code generation failed") } } } }

Today's Xcode release won't download the visionOS SDK, gives a 'network error'.
