I am trying to learn swift and have a problem with segmented controls.
I have an IBAction which will use switch to select 'Male' or 'Female'.
Here is the code:

Code Block @IBAction func genderButton(_ sender: UISegmentedControl) {
        switch segmentedControl.selectedSegmentIndex {
        case 0:
            userGender = "Female"
        case 1:
            userGender = "Male"
        default:
            return
        }
    }

However I get an error on the switch line:

Code Block Cannot find 'segmentedControl' in scope

I have looked on the web and the method looks OK to me, so why do I get this error?

Normally, you don't need the IBOutlet. With the code I proposed, it's enough to connect the IBAction.

Looks like you have not defined segmentedControl anywhere. In fact, you have to use sender (which is in fact the segmentedControl).

Just change as:

Code Block @IBAction func genderButton(_ sender: UISegmentedControl) {
        switch sender.selectedSegmentIndex {
        case 0:
            userGender = "Female"
        case 1:
            userGender = "Male"
        default:
            return
        }
    }

If that's OK, please don't forget to close the thread by marking the correct answer (it seems you have several other threads that you didn't close ; please do it as well)
