In some cases (for example, now), Xcode 6 does not display a drop-down list for selecting a schema menu. It is usually located next to the play button. In any case, I can not find access to this scheme even from the menu. How to enable it?
According to the docs , the "Schemes" menu should be on the toolbar. This is just access to the "Schema Editor". The Scheme Menu is not displayed.
Update / fix: Well, this is not a fix, but I understand that we can access the schematic editor from the menu: Product-> Scheme
A. I just upgraded to the OS X El Capitan GM semester. This may have something to do with it. But I'm sure I saw this problem several times in OS X Yosemite.
