Could not download IOS Simulator Xcode 12.4

Macbook Air M1, get the error in Xcode 12.4:

Could not download and install IOS 12.0 Simulator. Failed to download package from ADC. There are no valid accounts registered with Xcode that have the ability to access this resource. Contact Apple Developer Program Support to resolve account access issues.

I have never had this error on the previous Xcode and Macbook on intel chip. Please can you tell me how to solve it.


Hi Everyone,

I was following this issue and what worked for me is the following:

  • Go to the URL: https://developer.apple.com/download/all/
  • You will be asked to login with your developer account.
  • Download "iOS 17 Simulator Runtime". With Chrome, you also might get download paused but be patient. Eventually after a long time it will downloaded as Chrome has better built in tolerance to resume downloads.

  • Run the following command:
xcrun simctl runtime add "Path to downloaded dmg file"
e.g. xcrun simctl runtime add "~Downloads/iOS_17_Simulator_Runtime.dmg" 

And after that you should be able to continue with your app development. I hope it helps you

The simplest solution is to just sign in into your apple account on Xcode and launch back the download.

Follow the steps

  1. Xcode -> Settings -> Account -> Add account using the + icon
  2. Using the top tab for the same window select "Platform" then download the simulator

Now you are good to go.
