ios - Xib fatal error -

-

i have .xib called contentview.xib , set custom class subview of uiview. error when try , run app:

fatal error: init(coder:) has not been implemented:

here code: 

class contentview: uiview {       override init() {         super.init(frame: cgrect(             x: 0,             y: 0,             width: screen.width,             height: screen.height))           nsbundle.mainbundle().loadnibnamed("contentview", owner: self, options: nil)     }      required init(coder adecoder: nscoder) {         super.init(coder: adecoder)         fatalerror("init(coder:) has not been implemented:")     }

i have looked nscoder , couldn't find fix it.

it because of code:

fatalerror("init(coder:) has not been implemented:")

you raising assertion , crashing app yourself, remove code, work well.
