iOS 17.0 Simulator (21A328) Failed with HTTP status 400: bad request

Question

I update from Xcode 15 beta to Xcode 15.

I wanted to install the iOS package and got this error:

I already reinstalled Xcode.

There are already newer versions on the Apple site than what is shown here. Is that maybe where the error comes from?

Answer 1

Try the link https://download.developer.apple.com/Developer_Tools/iOS_17_Simulator_Runtime/iOS_17_Simulator_Runtime.dmg.

You can download it manually from here and install it using instruction from Installing and managing Simulator runtimes

After downloading, run:

xcrun simctl runtime add iOS_17_Simulator_Runtime.dmg

Worked perfectly for my colleague. It's weird that I never ran into the error on Xcode 15 though. I think I had installed ios 17 beta pretty early on maybe that's why. – Elaterin

For me it worked by downloading the stimulator through the command line.

Just type this command in the terminal:

xcodebuild -downloadPlatform iOS

Re "stimulator": This seems to be a write-only answer. What kind of stimulator? – Renfred

I also faced this issue, because of storage issue. But I am using a Apple M1 256 GB and I can't able to reduce my storage because system data is 150 GB.

I just downloaded the runtime from Apple and ran the following command in the terminal after download. It worked.

xcrun simctl runtime add iOS_17_Simulator_Runtime.dmg

I fixed it by flushing the DNS. Try this:

1. Open the Terminal app
2. Enter sudo dscacheutil -flushcache, enter your password if prompted
3. Enter sudo killall -HUP mDNSResponder
4. Reconnect your Wi-Fi / Ethernet connection

Or you can simply flush the DNS with CleanMyMac. Either method works just the same.

For me it didn't work. – Junkie

Answer 5

Just sign in with your Apple Developer account to Xcode → Signing in & capabilities → select Team, and it starts your downloading again. This works for me.

Answer 6

I have tried all the suggested methods, but none of them worked for me.

So I did go to App Store, and updated Xcode. After the update is done, running Xcode, it shows the list of simulators to install. Select iOS 17.0.

Then it works well.
