Xcode downloads but will not install iOS 17 and watchOS 10 SDKs

I get the same thing. I d/l and ran the iOS 17.0 CLI install as per the instructions given in this thread. It ran just fine. Opening Xcode, the canvas area still shows "iOS not installed." with a GET button.

My Xcode Platforms list shows:

macOS 14.0 - Built in

iOS 17.0(grayed out) - Get button

iOS 17.0.1 Simulator - 7.21 on disk

iOS 17.0 Simulator - 7.56 on disk

watch and tv are greyed out.

But i can't get the canvas to show up no matter what I do. I keep going in the same loop, get, install, launch, says it's not installed. Arg!!!!

Took a week off, opened my project I was working on today, and the preview window shows iOS 17.2 not installed, (GET).

WTF!

Tried the GET, downloaded again, don't know where it put it. I found my previous download in my downloads folder. Ran through the CLI install, AGAIN. That failed.

What do I need to do, pay Apple more $$???

I downloaded the latest iOS Sim. Tried to install from command line. It spit out the following error:

 sudo xcrun simctl runtime add "iOS_17.2_Simulator_Runtime.dmg"

D: 25269EA8-085B-446D-ABE4-38077DE1BDF3 iOS (17.2 - 21C62) (Unusable - Other Failure: Error Domain=SimDiskImageErrorDomain Code=5 "Duplicate of 8D3A7D3A-DC4B-4C6C-8F52-8F4B6FCFBE0C" UserInfo={NSLocalizedDescription=Duplicate of 8D3A7D3A-DC4B-4C6C-8F52-8F4B6FCFBE0C, unusableErrorDetail=})

I rebooted and tried again. It installed the second time, at least I think it did. There's no 'progress' to observe that it's doing anything.

I then opened Xcode and it's working.

Xcode installs this via the GUI, but it obviously doesn't work properly. Shouldn't someone make an effort to fix it?

After downloading 17.2 the download just showed it finished. Didnt do nothing. Downloaded 17.0, it did a verification at the end of the download and it got stuck again after that. Then I restarted the PC with "Reopen windows..." unchecked. Now it is showing me the device list again with the 2 new OS I downloaded.

WTF Apple??? Seems to be an issue with XCode 15.2 only. Me and my team encountered this issue at the same time

I had the same thing happen to me, but one of the responses mentioned that although the package was downloaded, it still needed to be installed.

Knowing that, I went into System Preferences and, lo and behold, saw that there was an available update for XCode that needed to be installed (it was because I had just downloaded that iOS 17.2 package).

So after clicking on this to install the update, I had to restart my computer to apply the change. I had already tried to apply the change by just quitting and reopening XCode, but that didn't work, so I took drastic measures and restarted the entire computer, lol.

Anyways, after giving XCode some time to load, this particular issue was resolved (I have to fix some more issues, but, at least, I'm past that one.)

Try (re)installing the desired simulators from the command line:

i have same problem, but restart work for me! hope it helps

You just need to restart the machine after you installed the desired version of iOS to your simulator.

work only sometimes. again and againt this is happening

I am just sitting here laughing, because I do not know what else to do, at the fact that I have followed this advice and it has worked.

Like. Oh, of course. I just had to restart my machine after installing this new software. That I thought I had installed and was using up until this morning when XCode informed me that I needed to install it.

After installing you need to restart the machine. Uncheck reopen current widows.

In case this helps

On a second look… If you’re really running macOS 14.0, update that, too. And check for a download of the latest Xcode at the developer website, if you have that access.
