I'm having a problem running my Xcode project on my Apple Watch. It says my iPhone + Apple Watch are ineligible because the OS on the watch doesn't support WatchKit App Products. My iPhone is running iOS 9 and my Watch is running watchOS 2. I've tried rebooting both devices and plugging/replugging in the iPhone.
i was seeing this as well. Tried reboots of mac, phone, and watch. Lots of error messages being displayed in console. I reinstalled xcode, installed the watchos profile on my phone, I also switched to a different lightning cable in a different port. After that last one opening Xcode and my phone appeared along with the watch. I'm still seeing RST requests in console from my phone but Xcode is at least acknowledging the devices. It could see the phone on its own in non watch projects.
Turns out switching the USB port did the trick. Thanks!
Didn't seem to work here - still getting the same problem.
Same problem here - have deleted symbols (more times that I can count), rebooted everything, no avail.
What is more fun is that whenever I unplug my iPhone Xcode 7 crashes.
