I came across several "errors" being reported when I run my app, however my app seems to function correctly. I believe they fall in the category listed on this ( now locked ) thread https://developer.apple.com/forums/thread/115461 However, I wanted to post the ones I found to clarify ( close to submission) just in case any of these end up being more than just log noise later. PLEASE let me know if you've come across these before and whether they impacted anything or if you can confirm they are just log noise. Thanks in advance! -[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:] perform input operation requires a valid sessionID. inputModality = Keyboard, inputOperation = , customInfoType = UIEmojiSearchOperations AVAudioSession_iOS.mm:2,223 Server returned an error from destroySession:.

Hello! When running tests on iOS 17, the build succeeds but does not run on iOS 16. It consistently gets stuck on 'Testing'. This issue does not occur on iOS 17.

Hello, I'm unable to run any test cases in Xcode 16 with the iOS 18 simulator. Steps to Reproduce: Create a new iOS project in Xcode 16 using the default iOS app template with the testing option checked. Run any test or UI test case by clicking the "Play" icon in the Test navigator. Xcode gets stuck at the "Testing" state indefinitely. Environment: macOS 15 beta 8 Xcode 16 beta 6 iOS 18 beta 7 simulator

Since the first beta of Xcode 16, randomly when editing a SwiftUI view a crash report opens with the message "PreviewShell quit unexpectedly." After that, annoyingly often the canvas fails to reload correctly, and shows this broken thing: The only way to get it working again is to restart Xcode, but it happens so often that it really impacts productivity. Does this happen to anyone else? If so, have you found a solution? I've already filed a report (FB14876223)

I am having issues with the Apple review process, the reviewer found some blockers on the iPad with 17.6.1. I don't have the physical device which I could use to reproduce the bags and neither on the Apple Downloads site nor via Xcode I am able to see the 17.6.1 simulators available. Is there any way I could download it? Any suggestions?

Hello, I would like to inquire about the release date of Swift Assist’s beta version. Apple has stated that it will be released later this year, but they have not provided a specific date or time. Could you please provide information on the beta version’s release date? Additionally, is there a trial version available? If so, when was it released? Thank you for your assistance.

Using Xcode 15.4, I have successfully built and run my app using Reality Composer Pro Version 1.0 package. I then successfully submitted that app version for release. Now, using Xcode 16 Beta 6, I've created a new branch repository for updating my app for iOS/iPadOS 18 and visionOS 2. However, once I created and switched to the new branch and did a build, I get build errors. It seems to be regarding the package manifest that relates to my Reality Composer Pro package that is part of my app. When I go to the package file in my project navigator and click the Open in Reality Composer Pro button, my package opens in Reality Composer Pro 2.0, which makes sense since it it the version for Xcode 16. However, I don't know how to address/get rid of the build errors. I've added and image of my build errors.

Really stumped on this issue my team is seeing with the Xcode 16 Beta (both Xcode 16 version 6 and Xcode 16.1). Wondering if anyone was having a similar issue and if this is a bug or something configured incorrectly. Basically, when I go to build settings and search for anything related to "Swift Compiler" nothing shows up. The only thing that appears with "Swift" in the title is under the User Defined keys (see attached) As such, I'm unable to change the Swift version for the project and I'm stuck in Swift 6 language mode which we're not quite ready for yet. This is only occurring on one of our targets. Our other app projects are behaving as expected. The project in question has the main target we build the project with and 2 support frameworks. The supporting frameworks are also working correctly. Its just the primary build target giving us fits. Curious if anyone is seeing something similar or has suggestions. Thanks!

Hello, Is anyone experiencing devices on OS 17 disconnecting from Xcode 15 and 16 Beta? I remember there were a lot of past conversations around the time when iOS 17 released but it seems to still be happening even after using Xcode 16 beta. Re-pairing devices and rebooting the hosts appear to fix it temporarily. I discovered that killing the remoted process also allows xcode to reconnect to the devices. Using Xcode 16's devicectl also doesn't work. I have my devices connected to a USB Hub and to multiple devices. The odd thing is I have iOS 16 devices connected and those don't disconnect. I believe iOS 17 introduced a new coredevice stack to connect but has anyone found a fix for it or have any recommendations? TN3158 isn't relevant in my situation because VPN and Packet filtering is not in use and I filed feedback with Apple but they have't responded in a long time.

When opening the package management sheet there is a loading indicator going forever preventing the button to be enabled. The window displays collections but not "Recently used" (which also loads indefinitely). Anyone else seeing this? Any way to clear Xcode preferences/caches for the manager?

Hi, The launchscreen section in Xcode 16 RC keeps disappearing no matter what. Is anyone else seeing this issue? I submitted a bug report over a week ago about this problem. Dan Uff

When I build and run my iOS app with Xcode 16.0 RC (16A242), it fails to run on both a physical iPhone (running iOS 18.0) and any iOS simulator (17.5, 18.0 RC tested). To be clear, this is an issue when running – there are zero build errors, and compilation always completes successfully. The same app, building and running from Xcode 15.4 (15F31d) runs on both a physical iPhone (same OS version) and an iOS simulator (same version) with no issues, and is currently deployed to TestFlight with no crashes at launch reported from users. Xcode 16's console logs the following: warning: (arm64) /Users/seb/Library/Developer/Xcode/DerivedData/Feed-bvzobcgzcnaibqbcwiasvpoxsetu/Build/Products/Debug-iphonesimulator/Feed.app/Feed empty dSYM file detected, dSYM was created with an executable with no debug info. No entry point found. Checked '(null)' I've so far tried a clean build, as well as clearing out my derived data folder entirely. Happy to provide any more info. Does anyone have any pointers as where I even start to debug this issue and narrow down on what's going on with Xcode 16?

I just swapped over to Xcode 16 and archived my build. I have ENABLE_BITCODE = NO in my Build settings (it's listed under user defined settings). When I go to validate the build, I get a failure "Invalid Executable, ***.framework contains bitcode". Nothing about my project settings has changed. If i swap back to Xcode 15 everything's fine when I validate. One thing I noticed though is that if I go through the process of validating, on the confirmation screen for Xcode 16 RC, the line about Bitcode: Not included does not exist like it does if I hit the confirmation screen in Xcode 15.

Hi! I’m trying to set up a launch screen image for my app. My goal is simple: I want my app icon to be displayed in the centre of the screen with a background colour. I do not want to use storyboards in my app. I realise that this is a very simple and common task, but I am struggling to find proper documentation on it. I am vaguely following the info.plist method from this page: https://developer.apple.com/documentation/xcode/specifying-your-apps-launch-screen/ I’m specifying my Image Name and Background Color. And everything plugs in and works except that the scale of the image is very unpredictable. I was hoping to make this work for all kinds of devices and screen sizes by simply using a transparent square image with my icon in the middle. I would have expected the image edges to be snapped to the screen borders and the image to be scaled uniformly to fit the screen. But no matter what resolution I try, 4k, 2k, 1k, the image gets scaled without any recognisable logic behind it. Does anybody know what image size is expected and if there is any way of achieving my goal?

I have some formatting strings that got in my string catalog, e.g. "%@" or "(%@)". However these strings are no longer used in my code anywhere (searching "In this project" in Xcode only matches the entries in my strings catalog), but Xcode does not remove them. I tried editing the file in a text editor, removing them manually but they keep coming back. Any solution for this? Xcode Version 15.4 (15F31d)

Issue: unresolvable because: Could not complete create template: empty template: Failed # variables.0.definitions.0.synomyms.0 I have no idea what this means.

Issue: unresolved variable(s) found: +applicationName I don't know how to fix this warning. Also need help figuring out what the other warning is. All showed up after upgrading to Xcode 16.
