uiviewcontroller - Property not initialized at super.init call -

i have next init method in view controller:

init(mainviewcontroller: uiviewcontroller, settingsviewcontroller: uiviewcontroller, gap: int) { self.mainviewcontroller = mainviewcontroller self.settingsviewcontroller = settingsviewcontroller self.gap = gap self.setupscrollview() // error here super.init(nibname: nil, bundle: nil) //and here. }

the self.setupscrollview method looks this:

func setupscrollview() { self.scrollview = uiscrollview(frame: cgrectzero) self.scrollview.settranslatesautoresizingmaskintoconstraints(false) self.view.addsubview(self.scrollview) }

the errors are:

self used before super.init call , property 'self.scrollview' not initialized @ super.init call

i've looked @ similar post without luck. help appreciated!

you can declaring scrollview optional , moving setup method phone call below super.init call. declaration this:

var scrollview : uiscrollview?

and initialisation:

init(mainviewcontroller: uiviewcontroller, settingsviewcontroller: uiviewcontroller, gap: int) { //other stuff super.init(nibname: nil, bundle: nil) self.setupscrollview() } func setupscrollview() { scrollview = uiscrollview(frame: cgrectzero) scrollview!.settranslatesautoresizingmaskintoconstraints(false) view.addsubview(scrollview!) }
