Cannot convert value of type '() -> _' to specified type 'Town.Size'

Question

Am getting this issue with this struct, on the line which reads \"lazy var townSize: Size ={\" and can\'t figure out what the issue is.

struct Town {

             


        

Answer 1

You incorrectly declared lazy var it should be declared like this

 lazy var townSize: Size = {
        switch self.population {
        case 0...10000:
            return Size.Small
        case 10001...100000:
            return Size.Medium
        default:
            return Size.Large
        }
    }()
