Common Mode Flag

A run loop pseudo-mode that manages objects monitored in the “common” modes.


Run loops never run in this mode. This pseudo-mode is used only as a special set of sources, timers, and observers that is shared by other modes. See Managing Observers for more details.



static let commonModes: CFRunLoopMode!

Objects added to a run loop using this value as the mode are monitored by all run loop modes that have been declared as a member of the set of “common” modes with CFRunLoopAddCommonMode(_:_:).
