Hello,
I'm checking to see if anyone else is experiencing an issue downloading the latest beta simulator.
When I try to download the iOS 26 beta 5 simulator in Xcode, the download fails instantly. There is no progress, just an immediate error with no message other than the code itself: DVTDownloadableErrorDomain Code: 41.
I've already restarted both Xcode and the Mac multiple times. I have also tried downloading on different networks to rule out a firewall issue.
Same here. Maybe unrelated but I noticed I installed the apple silicon Xcode and it's trying to install "ios 26.0 Universal Simulator (23A5308g)". Other (watchOS, tvOS, etc.) runtimes download fine it seems. I also do have an iOS 18.5 runtime installed but no other platforms so curious if that has something to do with it
Just fixed it.
xcodebuild -downloadPlatform iOS -architectureVariant arm64
just run that in terminal and it will download and appear in Xcode
Thank you for reporting that you're facing issue with this, and apologies! Could you please confirm if this is still reproducing after restarting Xcode?
Also, are you seeing this issue on macOS Tahoe, or on Sequoia?
Still seeing this issue after restarting Xcode, and after restarting my Mac. (macOS Sequoia 15.6)
What fixed it is downloading it from the command line: xcodebuild -downloadPlatform iOS -architectureVariant arm64
(After having first selected the Xcode beta as default in the command line tools.)
Yeh I'm pretty sure as the others have stated that it's trying to download as the universal XCode when we have silicon only xcode.
Without specifying the architecture using the command line it defaults to universal which is what XCode must be doing.
