I'm developing an iOS app that displays store locations on a map using Apple Maps (MapKit). I've limit the number of icons that can be displayed on the map to 100, but there's still huge performance issues and the app is very laggy even on modern iPhone models. What's the best practice when displaying a large number of icons on a map, should the icons be in PNG format with a small resolution (~10kb) or should the icons be vector (SVG) for best performance? Should I use the MapKit framework for iOS 17 or the UIKit approach?

Hey, I uploaded an app to Testflight and received these two Missing API declaration warnings. Is there something I am missing/wrong on the PrivacyInfo.xcprivacy file? Thanks so much!

I tried to run my Flutter app in Xcode in release mode, but I got the error: module 'cloud_firestore' not found. When I run my app in debug mode, everything works as expected. I also uploaded my app to the App Store for TestFlight and when I download it there it crashes, but only after I log in with Firebase Authentication. I have verified that the platform: iOS version in the pod file matches the deployment info in Xcode and I have verified that I have runner.xcworkspace open. I have also tried - delete Podfile - 'flutter clean' - 'flutter pub get' - 'flutter build ios' But I still get the error and I think this is the problem why my app crashes on the TestFlight. I am not using the latest version of Xcode, could this be a problem? What else can I do?

I am trying to setup a Virtual Machine environment for our CI/CD and I get the following error when I try to clone the source packages of the xcodebuild command in the disk mounted by the host in the vm to use it as a cache: Error Domain=NSPOSIXErrorDomain Code=62 "Too many levels of symbolic links" This error only shows up when the path of the option "clonedSourcePackagesDirPath" is set to the disk mounted by the host. On a directory inside the vm itself it works fine. We get the error with the macos target of the Lottie.xcframework since it's the only one to use symlink. We check and there is no cycle to be found. Anyone has any idea of how to solve this issue ? Or an explanation of what's going on there ?

I'm developing iOS framework with Objective C. I create a dispatch_queue_t by using dispatch_queue_create. And call CFRunLoopRun() for run the Runloop in the queue. But, It looks like the dispatch_queue_t has share the RunLoop. Some classes has add an invalid timer, and when I call the CFRunLoopRun(), It crashed on my side. Sample code: - (void)viewDidLoad { [super viewDidLoad]; self.queue1 = dispatch_queue_create("com.queue1", DISPATCH_QUEUE_CONCURRENT); self.queue2 = dispatch_queue_create("org.queue2", DISPATCH_QUEUE_CONCURRENT); } - (IBAction)btnButtonAction:(id)sender { dispatch_async(self.queue1, ^{ NSString *runloop = [NSString stringWithFormat:@"%@", CFRunLoopGetCurrent()]; runloop = [runloop substringWithRange:NSMakeRange(0, 22)]; NSLog(@"Queue1 %p run: %@", self.queue1, runloop); //NSTimer *timer = [[NSTimer alloc] initWithFireDate:[NSDate date] interval:1 target:self selector:@selector(wrongSeletor:) userInfo:nil repeats:NO]; //[[NSRunLoop currentRunLoop] addTimer:timer forMode:NSRunLoopCommonModes]; }); dispatch_async(self.queue2, ^{ NSString *runloop = [NSString stringWithFormat:@"%@", CFRunLoopGetCurrent()]; runloop = [runloop substringWithRange:NSMakeRange(0, 22)]; NSLog(@"Queue2 %p run: %@", self.queue2, runloop); CFRunLoopRun(); }); } Some time they take same RunLoop: https://i.stack.imgur.com/wGcv3.png ===== You can see the crash by uncomment the code of NSTimer. The NSTimer has been added in queue1, but it still running when call CFRunLoopRun() in queue2. I have read some description like: https://stackoverflow.com/questions/38000727/need-some-clarifications-about-dispatch-queue-thread-and-nsrunloop They told that: "system creates a run loop for the thread". But, in my check, they are sharing the RunLoop. This is sad for me, because I facing that crashes happen when calling CFRunLoopRun() on production. Can someone take a look at this.

At the beginning of the year, I transferred 3 applications from one account to another. Last month, I had to make changes and update two of them without any issues. Now, I need to update the third one, but in Xcode, I'm getting an error saying that the identifier can't be registered to my development team because it's not available. In App Store Connect, I can see all 3 applications perfectly. I have regenerated the certificates, but this third one is not appearing in the provisioning profiles. Any help?

Once I have the PDF generated by xcode: what exactly should I be doing with it?. Is there a place in Apple Connect where I should be uploading it?. If there's a place to upload it, will this mean that privacy manifest for our app will be updated by using this PDF? Do you have some documentation I can reference to where I can see the process of uploading this PDF? (not the process of how to create the xcprivacy file or how to add it to xcode nor all the properties that go in the plist file.)

When I try to list paired devices(like iphone with developer mode enabled and paired/connected with Xcode) using this command, I don't see it listed. xcrun simctl list pairs Can't see the paired devices in xcrun simctl list as well. I am on Sonoma 14.41 and the paired iphone is on ios17.2.1. Please advise.

Recently my live preview canvas on Xcode recently stopped accepting my keyboard inputs out of the blue when I type in a textField. Has this bug been addressed? I'm on iOS sim 17.4, Xcode 15.3

This is to see if anyone knows how to resolve this incident in the new version of XCODE 15.3 since it works fine in version 15.1 As you can see, when you open the component, the text type appears by default and the added library does not load nunitosan, when change to customs and search the font, it does not appear in the list. I would greatly appreciate any TIP or solution for this error in updating the tool.

Hey there! Got a question about font kerning: When adding a negative kerning to a text (changes via user input) the last character sometimes gets cut off: dropbox.com/s/49ucdzk8m4k61sj/fontproblem1.png?dl=0 dropbox.com/s/vmklvxp510wjeak/fontproblem2.png?dl=0 What i do is the following: Text("\(pos, specifier: "%.1f")") &#9;.font(.system(size: 100,design: .serif)) &#9;.fontWeight(.bold) &#9;.kerning(-5) When i remove the kerning it works, but as i understood the kerning keeps the letters as they are? Is there an alternative way of doing it?

Hello. I am trying to load my own Image Based Lighting file in a visionOS RealityView. I used the code you get when creating a new project from scratch and selecting the immersive space to full when creating the project. With the sample file Apple provides, it works. But when I put my image in PNG, HEIC or EXR format in the same location the example file was in, it doesn't load and the error states: Failed to find resource with name "SkyboxUpscaled2" in bundle In this image you can see the file "ImageBasedLight", which is the one that comes with the project and the file "SkyboxUpscaled2" which is my own in the .exr format. if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) do{ let resource = try await EnvironmentResource(named: "SkyboxUpscaled2") let iblComponent = ImageBasedLightComponent(source: .single(resource), intensityExponent: 0.25) immersiveContentEntity.components.set(iblComponent) immersiveContentEntity.components.set(ImageBasedLightReceiverComponent(imageBasedLight: immersiveContentEntity)) }catch{ print(error.localizedDescription) } Does anyone have an idea why the file is not found? Thanks in advance!

Hello, The Apple Watch's connectivity to Xcode has always been finicky. Sometimes it would start doing "transport errors" and you'd have to repair the watch/phone to xcode to resolve it. Now after the 10.4 upgrade, it seems that there are cases where the watch doesn't even show in the device list. Here's what I've observed: The watch will connect the first time you launch xcode(after 10.4 install or a new restore). If you unpair the watch, it will never show in the device list again. This is despite any remediation efforts, such as unpairing the phone from xcode, restarting the watch/phone, and clearing trusted devices. Erasing the watch and restoring it will allow it to connect again to xcode, but only if you never unpair it. If you unpair the watch, it will repeat the behavior of not showing in the device list again. So, the only solution is to erase/restore the watch to get it to show in the device list on xcode. Every single time. Again, this is new behavior for Watch OS 10.4
