I have tried to add the iOS6.1 simulator from the Xcode 4.6.3 package to Xcode 6, but it doesn't show up.
I followed the instructions on this post: How to Install Older iOS Simulators in XCode 4.2.1 (SDK5.0) to set it up and copied the "iPhoneSimulator6.1.sdk" to /Applications/Xcode/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDK. However it doesn't show up when trying to create a device.
Are there any extra steps I need to take?
