Xcode iOS project only shows "My Mac 64-bit" but not simulator or device

I figured it out. I had to edit the scheme (Product->Scheme->Edit Scheme...), and for some reason no executable was selected. I chose my app, saved and now I have my simulator and device options back.

Here is how I solved this problem. Right-click on the xcodeproj file and select "show package contents." Now delete everything inside the xcuserdata folder. Voila. I hope it helps anyone else out there that is facing this problem.

This is basically happen, when you change your project name or something like that. The solution is, you have to select the right "Scheme" for your project. Here is the solution :

After open your project :

1. Go to "Product" from upper menu
2. Select "Scheme" from the list
3. Then select "Manage Scheme"
4. Now no matter your "Project Name" is listed here or not just click on "Autocreate Schemes Now" from the upper-right side of the window.
5. Press "ok", now your project rebuild and you can find the "Simulator List" on the top.

Hope this help you guys.

Had the same problem.

None of the above solutions worked. In the end, I clicked on "Manage Schemes" and then "Autocreate Schemes Now". Then select the new scheme in Xcode. Now you will get back all device/simulator options.

This might be a bit nuclear option if you are midway through the project. My problem happened as I was starting on a new project and renamed the project. In this scenario, only autocreating a new scheme seemed to work.
