Optional variables as lazy?

[eonist]

Could we make the instance variable non-optional? Example:

lazy var someSize:CGSize = {
   let x:CGFloat = 0
   let y:CGFloat = 0
   let size = CGSize(x,y,0,0)
   return size
}()

//Now we can use someSize with out force unwrap 👌
//What happens is that the var isn't created until something asks for it.
print(someSize.x)
