Xcode Simulator: how to remove older unneeded devices?
ios, ios-simulator, xcode
Solution
Did you try to just delete the 4.3 SDK from within the Xcode Package?
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs
please also delete the corresponding .dmg file in
~/Library/Caches/com.apple.dt.Xcode/Downloads
to prevent Xcode from re-installing the same package again.
for XCode >= 6 see @praveen-matanam 's answer
Problem
I'm running Xcode 4.3.1 iOS-Simulator which originally only supports iOS 5.1. I need to test my code with iOS 4.3, so I used Xcode's "Install" feature to install it as described in "Installing Xcode with iOS 4.3 device simulator?" Now I'm finished with testing but cannot find a way to uninstall the 4.3 portions ("iPhone 4.3 Simulator" and "iPad 4.3 Simulator"). I want to reduce the clutter in the Scheme menu. No one on Apple's Xcode listserv knew the answer! EDIT: note that much has changed since Xcode 4.3, so suggest anyone reading this look at all the answers. The newest ones such as Steve Moser's may be of more use to you! EDIT 10/2017: Posted on Twitter by Julio Carrettoni If you are an iOS developer, execute this: `$ xcrun simctl delete unavailable` It removes old simulators Xcode no longer use. For me it was 6Gb Did not try it myself... [Also, I just saw Russ Bishop mentioned this in a comment below already...]
