CMTimebaseAddTimerDispatchSource and new libdispatch swift 3 version

Hi,

I’m migrating some code from swift 2 to swift 3, and I use the CoreMedia timebase API (CMSync). One of the functions I use is CMTimebaseAddTimerDispatchSource whose documentation (https://developer.apple.com/reference/coremedia/1489429-cmtimebaseaddtimerdispatchsource\) has not been updated and commands to use old swift 2 code (dispatch_source_create( DISPATCH_SOURCE_TYPE_TIMER, 0, 0, some_dispatch_queue )).
Is creating a timer source with DispatchSource.makeTimerSource() and casting it to DispatchSource the right way to go ?
