Hello,
As the static func wasn’t given a name, how does it apply to the finalPoint variable with the clamped function ?
Could you please explain the reason ?
Also, first time I see the method as " static func + " What makes it useful here ?
Hey!
You could say that “+” is the “name” of the function. But Swift considers that name to be an operator, so you don’t use it with encapsulating parentheses, like other functions.
We have a video on custom operators here: https://www.raywenderlich.com/1940612-advanced-swift-types-and-operations/lessons/6
