My development work is paused as Xcode is now non-functional on my Macs. Loading any project into Xcode soon leads to a hang and Force Quit. The SDKs are listed as "status unavailable". No Simulators are available.
I've tried previous versions of Xcode; removing everything and re-installing; installation from the Store and direct from the Apple Developer site.
I've created a Feedback issue.
This happens on both of my Mac minis.
I'm running Tahoe 26.4 (25E246) on both.
I've had something like this happening since 26.4 and thought I was the only one. Have been slowly considering wiping both my machines (happening on my MBP and Mac Studio).
Following for the moment and will check to see if any of these fixes work. I'm currently back on 26.3 (working for now) and have submitted a bug report about a month ago.
Anyone find a solution to this problem?
I am having the same issue, I woke up one morning and could not build my iOS app. The components area shows "Status unavailable" for all my platforms besides macOS. I have no way of re-downloading the runtimes and have gone through steps of rebooting my machine, deleting Xcode and re-installing, clearing out all the cache, downloading older Xcode, etc.
I have found no way to get Xcode to build my apps and no way to run an iOS simulator. A very frustrating problem as I have no idea what else I can do.
The only thing that seems to have had any reaction in Xcode at all is removing the Images.plist file, but even then I can't get it to the point where I can compile my app. It only gives me the ability to download the iOS platform via a "Get" button, at which point the actual download hangs.
Success! Xcode 26.5 Release Candidate (17F42) running on macOS Tahoe 26.5 Release Candidate (25F71) appears to have fixed the problem for me.
I first updated to macOS 26.5 RC, and then to Xcode 26.5 RC. I didn't need to clean out my previous installation data (e.g., /Library/Developer, etc.) ... I just deleted my 26.4.1 Xcode and replaced it with the new. My simulators showed up as expected. I did several reboots of my computer, and each time, the simulators briefly show as "status unavailable" but then they eventually show up and stay there.
Hopefully, others have the same the same success.
