Struct inside Protocol

I have a protocol which has a struct as a property:

struct Dimensions {
    var width: CGFloat
    var height: CGFloat
}

Protocol ShapeType {
    var dimensions: Dimensions {get set}
}

Now I have a class which is a subclass of SKShapeNode :

class Shapes: SKShapeNode, ShapeType {
    var dimensions: Dimensions

    override init {       // Error
        super.init()

        dimensions = Dimensions(width: 40, height: 40)
    }
}

I get this error:

Property 'self.dimensions' not initialized at super.init call

What is the proper way to inisialzie the struct inside the class?

You have to initialize self.dimensions before you call the super.init() method in your Shapes class initializer

init(dimensions: Dimensions) {
    self.dimensions = dimensions
    super.init()
}
