I've update Mac from OS X Yosemite 10.10.4 to OS X El Capitan 10.11.1 recently. After OS update the iOS device/Simulator list and Scheme option that appears right next to build/run option disappeared completely. I'm using Xcode 6.4.
I've found something new feature >> button next to Utilities tab on top-right corner after update to OS X El Capitan shown in screenshot. After clicking >> button Scheme button appears but is disabled.
Is this any kind of big or feature? Any fix/workaround?
I've seen this happen as well. The issue seems to be that the field will disappear if the window isn't wide enough. If you resize the window to make it wider, the run destinations field should appear.
The only solution is to use Xcode 7 or above. I've installed Xcode 7.1 and found Scheme/Simulator list available. Refer screenshot.
It seems that Xcode 6 or below doesn't support OS X El Capitan.
Got fix for using Xcode 6.x on OS X El Capitan.
For Scheme :
You can select scheme using Product menu -> Scheme -> Select Scheme
You can also edit, manage or add scheme using above steps.
For Destination :
You can select destination using Product menu -> Destination -> Select destination from drop-down list.
