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.

Lost connection to my iphone
I was developing on Xcode and downloading and testing just fine. Today when I connect (via cable), clean, build and run the system When I look in the iPhone ->settings -> General ->VPN & Device Management it does not list my developers tag. How do I get the two talking again. I have restarted the MAC (Xcode) and the iPhone multiple times.

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: :

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.

I changed something with Bundle Identifier... since then I cannot trust the certificate anymore on iPhone. It just won't show up. I reinstalled new profile, new bundle id, completely reinstalled iPhone... created new certificates, downloaded... nothing... I thinks it needs internet connection, but connection works just fine Unable to Verify App An internet connection is required to verify trust of the developer "Apple Development: My Name (22YBQVQJZK). This app will not be available until verified. this makes me crazy.. I lost like 5 hours on this.. still it does not work... Apple Intelligence tried like everything .. didn't help

How can I use private AI agents in Xcode 26.3?
I work on some proprietary codebases and can only use private AI services with them (currently MiniMax M2.1 and GLM 4.7). It all works great with both Claude Code and OpenCode agents, and I'd like to leverage the new agentic capabilities that are now in Xcode 26.3. I'm not seeing any option to connect to OpenCode, and both the Anthropic and OpenAI providers require an enterprise account (which I don't have access to). Are there any options that I'm missing here?

Verify App Process Never Verifies

But then I get an error message stating I need to Verify App via the Settings section "VPN & Device Management" I click on my account under "Developer App" and I trust my developer account. Then I am asked to "Verify App" And when I do so I can a spinning icon that spins for a minute.

Request: Option to Position Coding Assistant on the Right Side in Xcode
Dear Xcode Team, Please consider adding an option to position the Coding Assistant on the right side of the editor. Currently, when the assistant panel is open, it makes it difficult to access the Project Navigator at the same time. Having the ability to move the Coding Assistant to the right side would allow developers to keep the Project Navigator visible while interacting with the assistant, improving workflow and efficiency. Thank you

Linker trying to link Metal toolchain for every object file on Catalyst
When building our project for Mac Catalyst with Xcode 26.2, we get this warning almost a hundred times, once for every object file: directory not found for option '-L/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst' Somehow, every Link <FileName>.o build step got the following parameter, regardless if the target contained Metal files or not: -L/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst The toolchain is mounted at this point, but the directory usr/lib/swift/maccatalyst doesn't exist. When building the project for iOS, the option doesn't exist and the warning is not shown. We already check the build settings, but we couldn't find a reason why the linker is trying to link against the toolchain here. Even for targets that do contain Metal files, we get the following linker warning: search path '/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst' not found Is this a known issue? Is there a way to get rid of these warnings?

Active Membership but Xcode shows "Red X" at Certificates, Identifiers & Profiles
Hi everyone, I am struggling with a persistent issue regarding my Developer Program membership and Xcode syncing. Even though the Apple Developer Portal shows that my developer license is active and I have full access to App Store Connect, it is unfortunately not possible to sign applications with this account. It behaves as if the license wasn't active. The Symptoms: -Portal status: Active (Account Holder/Admin), -Xcode Settings: When I navigate to Settings > Accounts and select my team, there is a Red X displayed next to "Certificates, Identifiers & Profiles.", Xcode suggests there is an issue accessing these resources and I cannot sign any binaries. Confirmed the membership is active in the web portal. Everything seems configured correctly on the web side, but the account simply doesn't work locally in Xcode. Has anyone faced this specific "Red X" issue despite a valid membership? Is there a specific cache I need to clear or a way to force Xcode to re-fetch the correct status? Any advice on how to resolve this loop would be greatly appreciated. Thanks! :)

Xcode hangs on git network operations
In Xcode 26.3 and 26.4, when I use Xcode's built-in git functionality to do a "pull" or "fetch", Xcode presents a dialog saying it's performing the operation, but it never completes. The dialog remains on screen with a spinner. My remote repos are stored on a Mac mini on my local network and I access them via SSH. The git command line works fine, as does the tool Git Tower. I've filed this as FB22091014. Has anyone else seen this, and if so, found a solution?

Every Unity project with ARKit doesn't open in Testflight
Even when making a completely fresh Unity project, if I include ARKit and upload it to testflight, when I open it on my ipad it says 'Couldn't Load App'. If I don't include testflight the app opens fine. If I build the app directly to my ipad the app works fine. It opens if I set ARKit to 'optional' but then the AR doesn't work. I have included a camera and location usage description so it's not that. Really not sure what's going on, any help would be massively appreciated!

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.

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: :

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.

cannot run app on external iPhone
I changed something with Bundle Identifier... since then I cannot trust the certificate anymore on iPhone. It just won't show up. I reinstalled new profile, new bundle id, completely reinstalled iPhone... created new certificates, downloaded... nothing... I thinks it needs internet connection, but connection works just fine Unable to Verify App An internet connection is required to verify trust of the developer "Apple Development: My Name (22YBQVQJZK). This app will not be available until verified. this makes me crazy.. I lost like 5 hours on this.. still it does not work... Apple Intelligence tried like everything .. didn't help

How can I use private AI agents in Xcode 26.3?
I work on some proprietary codebases and can only use private AI services with them (currently MiniMax M2.1 and GLM 4.7). It all works great with both Claude Code and OpenCode agents, and I'd like to leverage the new agentic capabilities that are now in Xcode 26.3. I'm not seeing any option to connect to OpenCode, and both the Anthropic and OpenAI providers require an enterprise account (which I don't have access to). Are there any options that I'm missing here?

Verify App Process Never Verifies
I have an iOS app that I want to run on my device via Xcode and the USB-C cable. Once I run it through Xcode with my device as the target the app builds on device. But then I get an error message stating I need to Verify App via the Settings section "VPN & Device Management" I click on my account under "Developer App" and I trust my developer account. Then I am asked to "Verify App" And when I do so I can a spinning icon that spins for a minute. Spinning Icon stops and I still cant use the app. I have tried a couple of different things in particular Here is the Xcode error output : Domain: IDELaunchCoreDevice Code: 0 Recovery Suggestion: Verify that the Developer App certificate for your account is trusted on your device.

Request: Option to Position Coding Assistant on the Right Side in Xcode
Dear Xcode Team, Please consider adding an option to position the Coding Assistant on the right side of the editor. Currently, when the assistant panel is open, it makes it difficult to access the Project Navigator at the same time. Having the ability to move the Coding Assistant to the right side would allow developers to keep the Project Navigator visible while interacting with the assistant, improving workflow and efficiency. Thank you

Linker trying to link Metal toolchain for every object file on Catalyst
When building our project for Mac Catalyst with Xcode 26.2, we get this warning almost a hundred times, once for every object file: directory not found for option '-L/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst' Somehow, every Link <FileName>.o build step got the following parameter, regardless if the target contained Metal files or not: -L/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst The toolchain is mounted at this point, but the directory usr/lib/swift/maccatalyst doesn't exist. When building the project for iOS, the option doesn't exist and the warning is not shown. We already check the build settings, but we couldn't find a reason why the linker is trying to link against the toolchain here. Even for targets that do contain Metal files, we get the following linker warning: search path '/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst' not found Is this a known issue? Is there a way to get rid of these warnings?

Active Membership but Xcode shows "Red X" at Certificates, Identifiers & Profiles
Hi everyone, I am struggling with a persistent issue regarding my Developer Program membership and Xcode syncing. Even though the Apple Developer Portal shows that my developer license is active and I have full access to App Store Connect, it is unfortunately not possible to sign applications with this account. It behaves as if the license wasn't active. The Symptoms: -Portal status: Active (Account Holder/Admin), -Xcode Settings: When I navigate to Settings > Accounts and select my team, there is a Red X displayed next to "Certificates, Identifiers & Profiles.", Xcode suggests there is an issue accessing these resources and I cannot sign any binaries. Confirmed the membership is active in the web portal. Everything seems configured correctly on the web side, but the account simply doesn't work locally in Xcode. Has anyone faced this specific "Red X" issue despite a valid membership? Is there a specific cache I need to clear or a way to force Xcode to re-fetch the correct status? Any advice on how to resolve this loop would be greatly appreciated. Thanks! :)

Xcode hangs on git network operations
In Xcode 26.3 and 26.4, when I use Xcode's built-in git functionality to do a "pull" or "fetch", Xcode presents a dialog saying it's performing the operation, but it never completes. The dialog remains on screen with a spinner. My remote repos are stored on a Mac mini on my local network and I access them via SSH. The git command line works fine, as does the tool Git Tower. I've filed this as FB22091014. Has anyone else seen this, and if so, found a solution?

Every Unity project with ARKit doesn't open in Testflight
Even when making a completely fresh Unity project, if I include ARKit and upload it to testflight, when I open it on my ipad it says 'Couldn't Load App'. If I don't include testflight the app opens fine. If I build the app directly to my ipad the app works fine. It opens if I set ARKit to 'optional' but then the AR doesn't work. I have included a camera and location usage description so it's not that. Really not sure what's going on, any help would be massively appreciated!
