XCode 9.1 - Location simulation went missing

Question

I just updated my XCode to 9.1 today, and surprisingly I can't find "Allow location simulation" in scheme setting, please refer to the screenshot below:

Has any one got the same problem? And any suggestion that I can fix it?

Apple's getting worse and worse lately.

Answer 1

I had this issue as well and the fix was to run the application in the Simulator and then go to Edit Scheme while the Simulator was running and the Core Location option magically reappears.
