Hi Team, I am using Xcode 8.1 & 8.2.1 on Mac OSX High Sierra, I am able to build the code, but then its not getting installed on the Simulator.But I am able to run the code on device.I have reset the simulator, quit simulator,Xcode,restarted the machine,changed the location in pref.While trying to install the app,It shows the error "INVALID DEVICE STATE".Also some other error like "unable to find CoreSimulator".Is the Xcode 8.X is compatable with High Sierra?
Will Xcode 8 run on High Sierra
Is there some reason you aren't using latest Xcode 9.3.1 with macOS HS?
Is Xcode installed to /Applications? Did you rename it?
What iOS versions does that app support? Have you installed any sims in Xcode Preferences? How much free space on your SSD?
Which device are you trying to run in the simulator?
Run this in the terminal and see if any sims are found:
xcrun simctl list devices
