@discardableResult func doSomething() -> Bool {
    // does something
    return true
}

This function can be called in the following ways:

doSomething()

let didSucceed = doSomething()

Is there a way to differentiate the two from inside the doSomething() function, as in, is there a way to know if the caller is using the result?
