ios - Must call a designated initializer of the superclass 'UIViewController' in Swift 1.2 -

i have following init method worked perfect before swift 1.2.

init(items: nsarray, views: nsarray, showpagecontrol: bool, navbarbackground: uicolor){   super.init() 

in swift 1.2 line super.init() raises error:

must call designated initializer of superclass 'uiviewcontroller' 

the problem have 2 possible super init methods call 1 codec , other nib. both of not have access in init method.

see full class here line of error this.

how can correct init method make work swift 1.2?

full code

you writing view controller class other people use part of own app. if view controller have nib file, doing wrong , have been wrong: allow caller supply nib file name as 1 of parameters of initializer, call init(nibname:bundle:) , pass value along.

but gather view controller uses default empty automatic view, not problem in actual fact.

therefore you'll call init(nibname:bundle:), , since view controller has no nib file, pass nil nib name. in fact super.init() doing in earlier version of swift - calling init(nibname:bundle:) nil values you. nothing lost or changed.
