ios - warning : will never be excuted -

-

i updated old swift 1 app swift 2 using xcode 7 , i'm getting few warnings not there before updated.

 required init(coder adecoder: nscoder) {      fatalerror("init(coder:) has not been implemented")      // swift 2 update     state = .optionsvisible     super.init(coder: adecoder)! }

that function giving me 2 warnings both state , super lines not executed, i'm not sure why? figured changed between swift 1 , 2, i'm not sure what.

thanks!

fatalerror flagged @noreturn, compiler can tell nothing after executed.

this function st3 = (x, y) -> console.log "#{x?}, #{y?}" if [x?, y?] [true, true] # <- line 'good' 'bad' this output true, true bad i want able tuple comparison in python. in python, if can written as if (x, y) == (true, false): return 'good' the coffescript if loop translated javascript such if ([x != null, y != null] === [true, true]) { 'good'; } that's why not evaluated true. is there alternative way express in coffeescript? if want check see if of arguments not none , this: def check_all(*args): return all(arg not none arg in args) if wanted check if they're true (like literally true) use def check_all(*args): return all(arg true arg in args) if wanted take in list (instead of variable number of parameters, remove asterisk.
