Error in for loop CGFloat

Question

I converted a project from Swift 2 to Swift 3 and now I get an error in the following line:

for i:CGFloat in 0 ..< 2.0 + self.frame.size.width / ( skyText         


        

Answer 1

In essence what you want is still a loop through integer values incremented by 1. So you can just calculate the last int value and use a simple for each loop:

for i in 0..<Int(self.frame.size.width / ( skyTexture.size().width * 2.0 )) + 2 {
    //do your stuff here
    sprite.position = CGPoint(x: CGFloat(i) * sprite.size.width, y: sprite.size.height / 2.0 + groundTexture.size().height * 2.0)
}
