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.

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.
