I'm currently using initBy(ViewController(aDecoder)), but initBy is deprecated. The message tells me I can replace initBy with @OverrideInit on the constructor, but every time I do, I get an error: constructor with @OverrideInit doesn't override any super class constructor. Is there an example somewhere of how to use this annotation properly? It seems no matter what I do it doesn't work.

To “override” a constructor, your constructor should have the same parameter names and types.
Maybe you have wrong parameter names?
For example, in your code from previous thread you have constructor(aDecoder: NSCoder), and aDecoder parameter name doesn’t match super constructor.

Here is what I'm doing:

@ExportObjCClass
class ViewController @OverrideInit constructor(aDecoder: NSCoder) : UIViewController(aDecoder) {
    @ObjCOutlet lateinit var label: UILabel

I still see the error when compiling Error:(7, 1) constructor with @OverrideInit doesn't override any super class constructor.

Your constructor should have the same parameter names and types as super constructor, which is

constructor(coder: NSCoder)

So your constructor parameter should be coder: NSCoder too:

class ViewController @OverrideInit constructor(coder: NSCoder) : UIViewController(coder) {

Ah, that works! Thanks 🙂
