I've updated my Xcode to Xcode 6.3.2 (6D2105). Now all my existing Apple Watch projects no longer open the Apple Watch simulator (but code runs).
I've tried creeating a clean project as well and added the Watch target. The WatchKit App, Notifcation, and Glances targets run, but the Apple Watch simulator doesn't show up.
Only the iPhone target sim appears (and runs when that target is selected).
I'm I missing some new setting to configure the sim to appear?
PS: Running iPhone 6 / iOS 8.3 (12F69) sim
