Changing UIBarButton title shows ellipsis between old and new title

Question

When I'm dynamically changing a title of UIBarButton ellipsis shortly during changing:

I've tried to change frame of rightBarButton (make it wider), but it was not helpful. Any suggestions? Thanks

Set the button's possibleTitles property to the set of possible titles when you setup the bar button item.

let btnDoneSave = ...
// Other setup
btnDoneSave.possibleTitles = [ "Done", "Save" ]

There should also be a place in Interface Builder for filling in the possible titles if you are creating the bar button item there.
