title: iOS Simulator "could not find the SDK" and it "may need to be reinstalled"
body: <p>I tried running my app today using Xcode 4.6.1 in the iPhone 6.1 simulator, however it did not work. The app built successfully but then when the simulator opened it said "iOS Simulator could not find the SDK. The SDK may need to be reinstalled." When this happened, I went to Xcode> Preferences>Downloads and it said the iOS 6.0 simulator was installed. I decided I would give the app a try in a different simulator so I installed the iOS 5.1 simulator, however the same exact message came up again. Could someone please help me solve this?</p>
  
  <p>Thank you in advance and I really appreciate it.</p>
