Static variable inside of a function in Swift.

gistfile1.swift

func staticInsideFunction() {
    struct Temp { static var hasAnimated = false }
    if Temp.hasAnimated == false {
        // ... do something only on the first function call.
        Temp.hasAnimated = true
    } else {
        // ... do something on all subsequent function calls.
    }
}

Very nice. Thank you for sharing!

It didn't work for me and I've got the following errors:
Type 'Temp' nested in generic function 'myFunction' is not allowed
Static stored properties not yet supported in generic types

Any other suggestions?

any idea how to do this in Swift 3? can't seem to figure it out.

This looks genius. What are examples where you would use this pattern?
