Is there a way using Swift, to detect if iMessage is turned on, on the user's device? We have a need to warn a user if they have iMessage on (to boring to explain why) and would like to pop up a notice, if it's detected to be on.

A feature of Visual Studio which I’ve always missed in Xcode is the ability to quickly search for the selected text in the editor. Currently, after selecting the text I want to find, I have to hit cmd+c, cmd+f, cmd+v, then enter. Am I missing a shortcut? I would like to be able to select the text I’m looking for, then use a shortcut that would immediately search for the selected text in the current editor.
