Accessing instance variables in then block

[AndrewSB]

I can't seem to access class variables in my then block:

For example

class GradientView {
   let colors = ...
   lazy var gradientLayer = CAGradientLayer().then {
       $0.colors = self.colors // also tried colors
   }
}

doesn't work, but

class GradientView {
   let colors = ...
   lazy var gradientLayer: CAGradientLayer = {
       let layer = CAGradientLayer()
       layer.colors = self.colors
       return layer
   }()
}

does.

Can I repeat my old pattern of accessing instance variables in a lazy init using Then?

@AndrewSB, sorry for delay! It seems like a Swift bug. Adding type annotation to gradientLayer might work :)

class GradientView {
   let colors = ...
   lazy var gradientLayer: CAGradientLayer = CAGradientLayer().then {
       $0.colors = self.colors // also tried colors
   }
}

@AndrewSB, Doesn't it work?

It does! Thanks @devxoul!
