N unknown server-side error occurred while processing the command. Original error: Sdk '10.2.1' was not in list of simctl sdks

“An unknown server-side error occurred while processing the command. Original error: Sdk ‘10.2.1’ was not in list of simctl sdks” Any idea here?

I thought of downloading the sdk in xcode 8.3, but that shows only simulators upto 10.2 . Any idea on this

try using 10.3 as platform version!
