not get iPhone simulator option on xcode? see this bellow answer

Some time you not seen the iPhone simulator option on xcode and just see the "Mac 64-bit" option.

so for get iPhone simulator option on xcode just change base SDK in project -> Build Setting and just set  "latest ios sdk" option instead of other.
