I have a strange problem. I have an iPhone 6 which is on iOS 8.3 and I'm using Xcode 6.3. When my iPhone is not connected to Xcode, I can select the iPhone 6 simulator alright but when my device is connected, iPhone 6 disappears from the list. I wasn't able to test this with other devices since I only have an iPhone 6. Does this happen to everyone or is it just me? Is there a way to use the iPhone 6 simulator when my iPhone 6 is connected to the computer? Screenshots are below.
when connected:

when not connected:

Any help is much appreciated! Thanks in advance!
~/Library/Developerand/or~/Library/Application Support/Developerwill have an effect, as that's where Xcode stores stuff. However it looks like a bug to me, but a small one, given you know the solution if you want to use the iPhone 6 Simulator. - trojanfoe
