Since updating to watchOS 3 beta4, iOS 10 beta 4 and Xcode 8 beta4, I can no longer install and run apps from Xcode on my Apple Watch. I have made sure I have installed the beta4 configuration profiles for both iOS 10 and watchOS 3. I've made sure that my AppleID session has not expired in Xcode. I've unplugged/re-plugged the lightning cable multiple times. I've reset the AppleWatch at least 3 times and set it up again as a new device. Each time, Xcode will appear to start installing symbols by showing this line at the top/center of the Xcode window:
Installing Symbols for watchOS 3.0 (14S5302d) with a progress indicator that spins but never finishes.
Even while this is showing I can try to run apps on the watch. They will install (apparently) and I'll start to see the animated generic icon when the attempt to run but eventually the watch will just return to the watch face.
Has anyone else seen this and, if so, do you know what the workaround is to be able to run apps from Xcode again?
Thanks!
