I installed Xcode 15 beta 5 as well as the simulator, the iOS simulator runs very very slow, it takes nearly 30 mins to start the device, and after it's started, it's very lag, can anyone help?

I downloaded Xcode 15 beta 5 and I'm trying to work on my app, but it's having a problem with the simulator. It can't find the runtime I guess. This is the first time I've ran into this. When I try to run, this is what I get: The com.apple.CoreSimulator.SimRuntime.iOS-17-0 simulator runtime is not available. runtime profile not found using "System" match policy Download the com.apple.CoreSimulator.SimRuntime.iOS-17-0 simulator runtime from the Xcode Settings. Not sure what to do here. I also installed the latest iOS 17 developer beta on my device and Xcode doesn't work with that either. I can't help but think the development team forgot something here.

In Xcode 15 beta 6, building any Mac Catalyst project will encounter the following Linker warning. ld: warning: building for 'macCatalyst', but linking in dylib (/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa.tbd) built for 'macOS'

Xcode generates symbols for image and color assets now (which is super nice!). We noticed an issue when generating code symbols for our image assets. We have an image named inputContour and one named inputContourColor. Xcode was not able to generate a symbol for inputContourColor and instead produced the following warning: #warning("The \"inputContourColor\" image asset name resolves to the symbol \"inputContour\" which already exists. Try renaming the asset.") It turns out that the generator automatically removes the color suffix when creating the code symbol. For color assets, this probably make sense (so tealColor would become just teal), but this should not be applied to image resources.

We use Storyboards and custom fonts in our app. Once we started developing new features for iOS 17 and did the first build in Xcode 15, we've noticed that in quite a few places incorrect fonts are set to views. In some places it is incorrect weight, while in other it's completely different font. Some observations: Fonts may change the next time app is build. E.g., instead of SF Pro Display Semibold we got SF Pro Display Heavy, and then after few relaunches it switched to Nunito Bold 😵‍💫 We’ve ensured that correct font is set in Storyboard, and even tried to re-assign it. That didn’t help. All custom fonts are properly added to a target and are registered in info.plist All custom fonts are listed in UIFont.familyNames, so they are indeed registered with the system. Wrong fonts are loaded on both development environment and in TestFlight builds We’ve never experienced anything similar before Xcode 15 What we've tried: Re-assigning fonts in Storyboard. Creating new Storyboard in Xcode 15 and copying screens into it. I wonder if anybody else having similar issues and maybe knows the workaround. Thank you. P.S. I've filed a Feedback to Apple: FB12903371

=> Cannot copy the image because the disk is almost full The disk of my Mac is not full. Or is it another logical disk? Every time I try to install the iOS 17.0 simulator (21A5303d) it creates a copy of itself and fails. It is filling my HD and I do not know how to delete those files. And it differs by the last letter. Different versions? Registering simulator runtime with CoreSimulator failed.

I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData. My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).

Background Fetch debug was work properly in xcode 14。But was not work properly in Xcode 15 Beta 6. I have done these steps: -[x] Use Xcode - Debug - Simulate Background Fetch, performFetchWithCompletionHandler didnot receive the system callback. -[x] Use Xcode-Scheme-Edit Scheme-Run-Launch due to background fetch event。the feature is enable。but launch isn't background launch。and didnot receive the system callback。 Is it a bug in Xcode 15 Beta。 Could anyone give me some advices? Thank you

The Xcode Canvas Simulator (for Xcode 14 and even 15 ..beta 6) cause multiple springboard and diagnosticd processes to run at nearly 100% CPU , cause the MacBook M1 to heat. This happens every time. This is usually triggered after the Canvas show an error which live previewing the code as I edit it. I have tried clearing the derived data but it doesn't seem to help. This happens with all projects. I am unable to use live previews because of this issue. The are often other processes with the string Poster in them. Like PhotosPosterProvider , CollectionsPoster , ExtragalacticPoster running high on usage at the same time.

Hi ! We are super exited to switch to Xcode 15 when it will be released, but we have a major issue : Apps built with Xcode 15 beta fail to show DeviceActivityReport base view on iOS 16.

It's 100% reproductible with a very simple sample project If you guys could report the issue as well, it would be nice !

Xcode Cloud always exports archive using ad-hoc, development and app-store profiles. This uses up 5-6 more minutes always for my app. How to disable and allow export only in single distribution profile

Is it possible to reset the device list without paying the Apple Tax? I recently let my developer account lapse due to financial issues but it gets to me that I cant write and run apps I wrote on the phone I own. Now I cant even test them on it because I cant reset the device list. Is there any solution?

When using Xcode 15 beta 8 / iOS 17 beta 8 simulator runtime, we can see in Activity Monitor that memory used by "SimRenderServer" proccess grows significantly with each UI test run. It reproduces even on an empty test, that just wait for a second without launching the application. Memory usage doesn't go down when test run finishes, so each consecutive run adds more to it. For example, create an new project with a UI test // The contents of the test don't actually matter func testExample() async throws { try await Task.sleep(for: .seconds(1)) } Run this test repeatedly 100+ times and observe the "SimRenderServer" process in the Activity Monitor. From what we observed it only reproduces when "Preferred Capture Format" in the test plan configuration is set to "Video". Setting it back to "Screenshot" does no result in growing memory usage. This was reproducible on macOS Sonoma beta / macOS Ventura 13.5.1. Feedback was submitted FB13098749.

Hi there, i have recently started development in swift Ui. I wanted to ask whether it is possible to design an AR app which generates and tracks a 3d model or .scn based on a real world 3d model if .usdz format is used. for example i want to generate and track the movement of an aeroplane in AR and i have .scn file but i want a real world object as an anchor like a pen or pencil and i want to use its 3d data in .usdz format. i know you can use ARobjects abnd object tracking but it uses .arobject format and doesnot use LiDAR. important thing is that i want to use Lidar tracking not point cloud. is it possible? point me in right direction Thank you. I am using xcode 15 & ios 17 beta

Hi, since a while now, I've noticed that in Xcode 15 (beta 8), my iOS device running iOS 17 (latest beta), I can't seem to disable the setting "Connect via Network" in the Devices and Simulators window. The controls are disabled, and stuck to 'on'. I often also have issues with the 'Installing to device' step while development my apps, where a reboot of the iPad is required. My guess is that it gets stuck/confused how it is supposed to deploy and my network setup is a bit complicated due to VPN's, tight WiFi security etc. Unpairing the device doesn't help with resetting this setting. After unpairing the top-right header (with the Take Screenshot controls etc...) even still shows the details of the unpaired device. Anyone else has experienced this or know a solution.

I have verified on developer.apple.com under Certificates, Identifiers & Profiles that my device‘s Device ID (UUID) as listed. I have NO problem building & installing this app to my iPad, nor any problems installing other of my apps to this iPhone - it’s just this app on the phone that’s messed up.

In stringsdict it was possible to define a format separately from the translation so you could do something like "n_days" which you could pass in an integer and it would return you only "Day" or "Days" without the actual value in it. And it's work great. But now with the strings catalog it seems like the format specifier HAS to be in the value, otherwise it's not recognized. Is there now no way to pluralize anything without having the actual value inside the translation? Cannot infer format specifier for string group because no numerical specifiers were found (en: %d.n_hours)
