Hi everyone, I’m experiencing a persistent issue when trying to download the iOS Simulator Runtime 26.1 on Xcode (version 26.1). The download always fails with the following error Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 I’m located in Brazil, so I initially thought it might be region-related, but I’ve already tried several attempts to fix it, including: Using VPNs for the US and Europe Installing the Xcode 26.2 beta Downgrading Xcode to earlier versions Reinstalling the same version of Xcode Restarting Xcode and my Mac Switching networks Clearing simulator support/device files Unfortunately, nothing has resolved the issue. Is anyone else facing this problem? Does anyone know a workaround or a manual way to download/install the iOS 26.1 simulator runtime? Thanks in advance!

This is from Mac OS 26 or the prior version. It seems to be trying to include XCTest, but its no where in the build phases or frameworks? Anyone seen this issue?

Hey guys, I updated to macOS Tahoe and after that I tried installing Xcode 26, but I always get an error message saying it can’t complete the installation, both through the App Store and via direct download from Apple’s website. Is anyone else having this same issue?

Hi everyone, I'm experiencing a persistent issue for months now where I'm unable to download the iOS 26 simulator Runtime. I've tried reinstalling Xcode and also Xcode Beta but same issue. iOS 26 Simulator is also not on developers download page, so manual installation is impossible. And sadly I can't compile any code without having iOS 26 simulator installed. Anyone able to get passed this? Hardware: M1 Pro OS: Tahoe 26.1 Heres the error Download failed.

I am missing device support for IOS 18.5 in xcode. I tried installing xcode 16.4, xcode 16.4 beta and xcode 26 beta 2 but none of them generated folder for 18.5. Is this happening only for me or everyone. Please provide me 18.5 folder if anyone has it. I would appreciate a lot.

Hello, We're attempting to validate our application archive through Xcode but the application is crashing during the validate step and we're not sure why. Platform: macOS 15.1 Arch: arm64 We've confirmed that our developer agreements are up to date (a suggestion made by other posts on these forums). Other suggestions have been to downgrade Xcode but we're hoping there's another explanation. The application is quite complex - many libraries and framework - but executes as expected during development and testing. Crash Report Any insight into this error would be appreciated. We're sure it's something wrong with our plist or archive structure but the crash is limiting our ability to debug.

Good day! When your project have total 887 or more SPM local targets and then you try to build it, xcodebuild will be crash.

I have a very annoying problem when I try to distribute my app to the App Store. Organizer does not recognise the project as an app I think. Xcode version is 16.2 but I have tries in 15.4.

From time to time while I'm editing code, Xcode 15.0.1 says "The file 'project.xcworkspace' has been modified by another application" asking me "Keep Xcode Version" or "Use Version on Disk". I didn't see this before 15.0.1 (or 14.1.1). Who changed the file? What should my answer be? 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.

I want to use a ci_script to change the CI_BUILD_NUMBER to a new value. But in XCODE CLOUD there seems to be no programmatic way to change it?

I'm trying to bring up an existing macOS app workspace to build against the macOS 26 SDK, however Xcode 26b1 is producing the following error, and I'm unable to proceed: /Users/tonyarnold/Documents/Reveal/<unknown>:1:1: error reading '/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/include/module.modulemap': No such file or directory /Users/tonyarnold/Documents/Reveal/<unknown>:1:1: failed to emit precompiled module '/Users/tonyarnold/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/_Builtin_stdbool-LVR359SH1U4537HG9T3JOGN.pcm' for module map '/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/include/module.modulemap' I've checked and the module map that it claims is missing is there on the filesystem. Is this a known issue with this beta?

Anyone else notice that Xcode 16.1 seems to have stopped building universal binaries for both debug and release builds even though under "Build Settings-Build Active Architecture" both Debug and Release are set to NO. We had been using the universal binary builds out of Debug for preliminary tests on Intel based machines. The Architectures setting is set to: Standard Architectures (Apple Silicon, Intel) - $(ARCHS_STANDARD). I started a brand new empty app and it does the same thing. A workaround is to set the Destination in Xcode's menu bar to "Build on Any Mac" and then find the binary and drag it to the Intel computer. You can't run that one though from Xcode. Another workaround is to build an Archive and drag that one.

Hi Apple Developer Community. I have a problem with opening my Xcode File in Xcode 16. It says, that a specific File is missing and I don't know how to resolve this. Can someone help me? Thanks for the help :)

Since iOS 18.2 the simulators have been missing the content under Apps menu for Settings. We are on to iOS 18.3 and still no Apps settings. @dts

Hi, I am in the last step "preparing for submission" and everything excepts "age rating" is fine. How can I fix this? I have two apps and on neither i can edit "age rating" :(

This is the Icon Composer from Xcode 26.0 Beta 1 (not the really old one Xcode6? 😆 that I find when I search here) Is there a way to show the really cool 3D that they showed off during demos? Maybe all we get is which level is on top. Upon export it only seems to be able to do 2x? - is there some way to get it to take 1x? Every time I change it - it jumps back to 2x and iOS wants 1x... maybe a feedback. Also Xcode seems to want 3 icons - but there are 6 iOS ones exported. How do I get the other 3 in there? It does seem pretty easy to import PNG's from Sketch and order them and move pieces around. I guess you can save individual lighting for each icon mode.

Canvas Previews (targeting macOS) in both Xcode 16.4 & Xcode 26 fail to load, when the project imports a Swift package that imports and uses WebKit. I'm on macOS 15.5. Tried also to bring minimum targets of both the project and the package to 15.0. I see that there are some work-arounds for iOS simulator but nothing for the Mac. Anyone facing the same problem?
