Red "X" showing up for Certificates, Identifiers, & Profiles in xcode
I've upgraded to a new Macbook recently, just when I was setting up my Xcode, I realized I there is a this red "X" showing up next to my development team as I was signing in to my account I have checked my permission on App Store Connect, everything seemed fine. I have also deleted my old Apple development certificate and requested for another one. Nothing worked.

Swift compiler fails in Release (-O) when using generic ObservableObject with @Published on iOS < 26 in Xcode 26.3
When building a SwiftUI project in Xcode 26.3, Swift compilation fails in the Release configuration with Optimization Level set to -O, when the iOS deployment target is lower than iOS 26 (e.g. iOS 16, 17, or 18). The failure occurs when using a generic class conforming to ObservableObject that contains a @Published property. The same code: Compiles successfully in Xcode 16.3 (Release, -O) with iOS 16/17/18 Compiles successfully in Xcode 26.x when the deployment target is set to iOS 26 Compiles successfully in Xcode 26.x Debug configuration (-Onone) Compiles successfully in Xcode 26.x Release when optimization is disabled (-Onone) However, in Xcode 26.3, the build consistently fails in Release (-O) when targeting iOS 16, 17, or 18. This appears to be a Swift compiler optimization issue related to generics, ObservableObject, @Published, and back-deployment to iOS versions prior to iOS 26. STEPS TO REPRODUCE Create a new SwiftUI App project using Xcode 26.3. Leave all project settings at default (Swift version 5). Set the iOS Deployment Target to iOS 16, 17, or 18. Use the following minimal code: import SwiftUI internal import Combine @MainActor class CommonViewModel<Item>: ObservableObject { @Published var listArray = [Item]() } class ContentViewModel: CommonViewModel<String> { func reloadData() { self.listArray = ["1"] } } struct ContentView: View { @StateObject private var viewModel = ContentViewModel() var body: some View { Color.clear .onAppear { viewModel.reloadData() } } } Build and run the app using the Release configuration.

Can I move Xcode files to an external SSD safely?
Hi everyone, I’m running out of space on my Mac and I need to use an external SSD to free up room, especially because Xcode is taking a lot of storage. I want to know if it’s safe to move some Xcode files—projects, derived data, or system-related files—to an external SSD. Which files can I move safely, and which should stay on the internal drive? I want to avoid breaking anything or causing issues with Xcode or macOS. Also, is it the same situation if I use an external HDD instead of an SSD? Are there additional risks or performance issues to consider?

how to inhibit -fprofile-instr-generate passed to linker
I'm struggling to build a driver for iPadOS in a particular project configuration. If I put the driver code and dext target into the same Xcode project which contains the iPad app, all is well. This is the way the Xcode driver template does it. However, I'd like to build and debug the dext on macOS, while eventually deploying on iPadOS. So I put the dext into a different project, which has a macOS target, a minimal iPadOS target and a DriverKit target. I made a workspace which contains both projects. I dragged the macOS project into the iPadOS project so that I can refer to the products of the macOS project (specifically, its driver target) as a dependency of the iPadOS target. Note that the main iPad app target depends on the driver target. So the workspace organization looks like this: Workspace iPad project main iPad app target (depends on driver) test project reference test project test macOS/iPad app target DriverKit dext target When I build the iPadOS target, it builds the dependent driver target in the macOS project, but it fails to link because Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/15.0.0/lib/darwin/libclang_rt.profile_driverkit.a is not found. If I just build the driver target directly in Xcode, there is no such complaint. I looked closely at the build logs, and I see for the failed link, there are these two linker flags set which are not set in the successful case -debug_variant -fprofile-instr-generate I can't seem to control the generation of this flag. I tried turning off the Profile switch in the Scheme editor for the driver, but is makes no difference. When I directly build the driver target, no -fprofile-instr-generate is set and it compiles and links. When i build the driver as a dependency of another target, -fprofile-instr-generate is passed to the linker, which fails. The obvious workaround is to put the driver source code into a separate driver target in the iPadOS project, but I'd rather have just one DriverKit driver for both platforms, with a few settings (such as bundle ID) controlled by a configuration file. Has anyone else encountered this problem, and know of a workaround?

Xcode 26.3 incompatible with FireBase and WeTest?
Popular automated testing systems like FireBase [1] and WeTest [2] expect the uploaded test to include the Debug-iphoneos directory generated by Xcode. However, in all of our builds on Xcode 26.3, this folder is created but remains empty. There are some other folders with the same name in subdirectories, but these only contain intermediate build files. Now we're looking for configuration or settings in Xcode to restore the original behavior, where the top-level Debug-iphoneos directory gets populated with a complete image of the test target, include the binary and resource files. Any suggestions would be much appreciated! [1] https://firebase.google.com/docs/test-lab/ios/run-xctest [2] https://www.wetest.net/documents/detail/automation/d8yaA7yz

Is it possible to download or copy the iOS SDK for Xcode 26.1 using command-line tools? If so, how?
I have Xcode 26.1.1 (installed on a Mac Mini with Sequoia 15.7.2), which was installed from the Universal .xip file available from the Apple Developer site. This file is 2.7Gb. When Xcode is run, there is a menu item at Settings -> Components, and the top section "Platform Support" includes an option to "Get" the iOS SDK, which is an additional 10.3Gb download.[1][2] I would like to either use command-line tools to obtain this iOS SDK component, or find where the downloaded package or its contents are installed on this Mac. This Apple Documentation some examples of using command-line tools to download components for Xcode. However, there is no specific documentation on how to separately download the iOS SDK. It seems that if possible, it could be done with "xcodebuild -downloadComponent", however I have tried a number of likely component names (ios, ios_sdk, ios26.1, ios_sdk26.1, iphoneos, iphoneos_sdk, iphoneos_sdk26.1), and none are valid. Does anyone know either where the SDK download can be found, or how to download it using command-line tools? Background: I require this as I am managing a fleet of Mac Minis located in a data centre (used for iOS/Android builds), and Internet access is restricted - any action requiring Internet access needs the Mac to be removed from the machine room racks and taken to a build room, then connected to a mobile hotspot or similar. This access is slow, and the above 10.3Gb download can take over an hour. If I can download the SDK separately, I can distribute it to all of the Macs over the internal network overnight, in advance of visiting the DC for upgrade tasks. [1] Various web sites say that the iOS SDK is "bundled with" Xcode. However, if that's the case a) how is a 10.3Gb download somehow included in a 2.7Gb file? And b) why do I still need to "Get" this component after installing Xcode from the 2.7Gb file? [2] Note that I am not looking for the iOS Simulator, I have already downloaded the iOS 26.1 version of this. I am specifically looking for the iOS SDK as listed under "Platform Support" in the Xcode menu described above.

Can't specify platform version for xcodebuild download 26.x
Prior to iOS 26.0 we were able to download specific simulator runtimes from the command line by using a command like xcodebuild -downloadPlatform iOS -buildVersion 18.0 This is described in the documentation here. This no longer works for 26.x. If I run the following command: "xcodebuild -downloadPlatform iOS -buildVersion 26.0" it fails with the following error: "Finding content... iOS 26.0 is not available for download." If I omit the -buildVersion flag it will download the latest version, currently 26.2, but if I try and specify 26.2 as the buildVersion I still get "iOS 26.2 is not available for download". This behavior has been confirmed on Xcode 26.2. Perhaps related, it appears these runtimes are also no longer being made available for download on https://developer.apple.com/download/all

Latest Beta Version Breaks Xcode Testing Builds on Physical devices.
This is a grave issue I am facing while testing my apps on my personal device. This is the error I seem to be getting: "The application could not be launched because the Developer App Certificate is not trusted." And on the phone side, this is the message: Unable to Verify App. An internet connection is required to verify the trust of the developer "Apple Development... Before I receive any recommendations, such as deleting Xcode or restarting my device, I would like to clarify that I have already taken all necessary precautions. The application I was testing appeared to function correctly in the morning a few hours prior to the update. However, after upgrading to the latest beta builds, iOS 26.4 beta and the latest macOS beta, this issue has become a recurring problem. I would greatly appreciate your assistance in resolving this matter, as it is of utmost importance to me.

"Unable to verify app" cannot verify trust of developer
I've seen a couple posts on reddit today but wanted to call out here because I think it may be a more widespread issue - I keep getting an error trying to open my iOS app saying "Unable to verify app - An internet connection is required to verify trust of the developer...". I have never gotten this issue before and did not change anything in my build settings from my last successful build of the app to now. The directions it gives me are to go to Settings > General > VPN and Device Management and trust my developer certificate from there, but that doesn't work either. The first time I tried this, the developer certificate wasn't there at all, then I looked at Reddit and saw people recommending to download the developer certificate to solve the issue, but doing this did not fix the error either. Just looking to see if anyone else has encountered this or what the fix might be.

MacOS and iOS all running 26.4 Beta 3. Does anyone know if we have to wait for Xcode 26.4 Beta 3 and it's associated SDK's for this one to become available?

Is it possible to download or copy the iOS SDK for Xcode 26.1 using command-line tools? If so, how?
I have Xcode 26.1.1 (installed on a Mac Mini with Sequoia 15.7.2), which was installed from the Universal .xip file available from the Apple Developer site. This file is 2.7Gb. When Xcode is run, there is a menu item at Settings -> Components, and the top section "Platform Support" includes an option to "Get" the iOS SDK, which is an additional 10.3Gb download.[1][2] I would like to either use command-line tools to obtain this iOS SDK component, or find where the downloaded package or its contents are installed on this Mac. This Apple Documentation some examples of using command-line tools to download components for Xcode. However, there is no specific documentation on how to separately download the iOS SDK. It seems that if possible, it could be done with "xcodebuild -downloadComponent", however I have tried a number of likely component names (ios, ios_sdk, ios26.1, ios_sdk26.1, iphoneos, iphoneos_sdk, iphoneos_sdk26.1), and none are valid. Does anyone know either where the SDK download can be found, or how to download it using command-line tools? Background: I require this as I am managing a fleet of Mac Minis located in a data centre (used for iOS/Android builds), and Internet access is restricted - any action requiring Internet access needs the Mac to be removed from the machine room racks and taken to a build room, then connected to a mobile hotspot or similar. This access is slow, and the above 10.3Gb download can take over an hour. If I can download the SDK separately, I can distribute it to all of the Macs over the internal network overnight, in advance of visiting the DC for upgrade tasks. [1] Various web sites say that the iOS SDK is "bundled with" Xcode. However, if that's the case a) how is a 10.3Gb download somehow included in a 2.7Gb file? And b) why do I still need to "Get" this component after installing Xcode from the 2.7Gb file? [2] Note that I am not looking for the iOS Simulator, I have already downloaded the iOS 26.1 version of this. I am specifically looking for the iOS SDK as listed under "Platform Support" in the Xcode menu described above.

Can't specify platform version for xcodebuild download 26.x
Prior to iOS 26.0 we were able to download specific simulator runtimes from the command line by using a command like xcodebuild -downloadPlatform iOS -buildVersion 18.0 This is described in the documentation here. This no longer works for 26.x. If I run the following command: "xcodebuild -downloadPlatform iOS -buildVersion 26.0" it fails with the following error: "Finding content... iOS 26.0 is not available for download." If I omit the -buildVersion flag it will download the latest version, currently 26.2, but if I try and specify 26.2 as the buildVersion I still get "iOS 26.2 is not available for download". This behavior has been confirmed on Xcode 26.2. Perhaps related, it appears these runtimes are also no longer being made available for download on https://developer.apple.com/download/all

Orphaned XCode simulator disk images
Recently I noticed that although my drive showed ~800Gb of usage, the folders within totally to around ~600Gb (and yes I was including hidden 'dot' files/folders. After some inspection I found that there are a whole set of Disk Media Images, that appear to be related to XCode simulators. Here's an extract from the command line diskutil list command: /dev/disk5 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +17.6 GB disk5 Physical Store disk4s1 1: APFS Volume iOS 26.2 Simulator 17.1 GB disk5s1 /dev/disk6 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +14.2 GB disk6 1: Apple_APFS Container disk7 14.2 GB disk6s1 /dev/disk7 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +14.2 GB disk7 Physical Store disk6s1 1: APFS Volume XROS 26.2 Simulator 13.8 GB disk7s1 /dev/disk8 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +17.2 GB disk8 1: Apple_APFS Container disk9 17.2 GB disk8s1 /dev/disk9 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +17.2 GB disk9 Physical Store disk8s1 1: APFS Volume iOS 26.0 Simulator 16.7 GB disk9s1 /dev/disk10 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +8.5 GB disk10 1: Apple_APFS Container disk11 8.5 GB disk10s1 /dev/disk11 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +8.5 GB disk11 Physical Store disk10s1 1: APFS Volume XROS 2.5 Simulator B... 8.2 GB disk11s1 /dev/disk12 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +18.0 GB disk12 1: Apple_APFS Container disk13 18.0 GB disk12s1 /dev/disk13 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +18.0 GB disk13 Physical Store disk12s1 1: APFS Volume XROS 2.5 Simulator 17.5 GB disk13s1 /dev/disk14 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +17.6 GB disk14 1: Apple_APFS Container disk15 17.6 GB disk14s1 /dev/disk15 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +17.6 GB disk15 Physical Store disk14s1 1: APFS Volume iOS 26.1 Simulator 17.1 GB disk15s1 /dev/disk16 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +14.1 GB disk16 1: Apple_APFS Container disk17 14.1 GB disk16s1 /dev/disk17 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +14.1 GB disk17 Physical Store disk16s1 1: APFS Volume XROS 26.1 Simulator 13.7 GB disk17s1 /dev/disk18 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +17.6 GB disk18 1: Apple_APFS Container disk19 17.6 GB disk18s1 /dev/disk19 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +17.6 GB disk19 Physical Store disk18s1 1: APFS Volume iOS 26.1 Simulator 17.1 GB disk19s1 /dev/disk20 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +9.1 GB disk20 1: Apple_APFS Container disk21 9.1 GB disk20s1 /dev/disk21 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +9.1 GB disk21 Physical Store disk20s1 1: APFS Volume iOS 18.5 Simulator B... 8.8 GB disk21s1 /dev/disk22 (disk image): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme +20.7 GB disk22 1: Apple_APFS Container disk23 20.7 GB disk22s1 /dev/disk23 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +20.7 GB disk23 Physical Store disk22s1 1: APFS Volume iOS 18.5 Simulator 20.2 GB disk23s1 I am unable to unmount them, either from the command line or Disk Utility.

I'am porting my App to Swift 6...
... and I managed to fix most issues coming out, but for a specific issue in an class adopting a protocol; basically it is a support class to be used by the view controller and so I wanted to keep it in background, so I created a new actor and I wanted to use it for this protocol and adopting classes. Yet I came out with a host of errors I have no idea about how to cope with: :

Xcode Devices "Download Container" no longer works on latest Xcode 26.0 (24228) (Build 17A324)

Latest Beta Version Breaks Xcode Testing Builds on Physical devices.
This is a grave issue I am facing while testing my apps on my personal device. This is the error I seem to be getting: "The application could not be launched because the Developer App Certificate is not trusted." And on the phone side, this is the message: Unable to Verify App. An internet connection is required to verify the trust of the developer "Apple Development... Before I receive any recommendations, such as deleting Xcode or restarting my device, I would like to clarify that I have already taken all necessary precautions. The application I was testing appeared to function correctly in the morning a few hours prior to the update. However, after upgrading to the latest beta builds, iOS 26.4 beta and the latest macOS beta, this issue has become a recurring problem. I would greatly appreciate your assistance in resolving this matter, as it is of utmost importance to me.

"Unable to verify app" cannot verify trust of developer
I've seen a couple posts on reddit today but wanted to call out here because I think it may be a more widespread issue - I keep getting an error trying to open my iOS app saying "Unable to verify app - An internet connection is required to verify trust of the developer...". I have never gotten this issue before and did not change anything in my build settings from my last successful build of the app to now. The directions it gives me are to go to Settings > General > VPN and Device Management and trust my developer certificate from there, but that doesn't work either. The first time I tried this, the developer certificate wasn't there at all, then I looked at Reddit and saw people recommending to download the developer certificate to solve the issue, but doing this did not fix the error either. Just looking to see if anyone else has encountered this or what the fix might be.
