Because you wrote `let bezierPath = UIBezierPath()` in the middle of a type definition, and in all other types, you would get a new bezier path for each instance.
struct Struct {
let bezierPath = UIBezierPath() // per instance
}
class Class {
let bezierPath = UIBezierPath() // per instance
}
func function() {
let bezierPath = UIBezierPath() // per call
}
enum Enum {
case aCase {
let bezierPath = UIBezierPath() // shared?!?!
}
}
