How to show image title instead of icon in xcode code?

Related: I like the literals; to find out the name of the image after-the-fact, have Xcode reveal the name of the image asset by selecting the literal, then press Cmd-E, "Use Selection for Find". The image's name will show in the Find bar, e.g. #imageLiteral(resourceName: "icn_spinner")

Alternatively, press Cmd-/ to comment the line out; the commented form contains the literal text.
