Type “myViewController” does not conform to protocol UIPIckerDataSource in Swift

Question

I just create a new class in Swift, it\'s called myViewController and it\'s a UIViewController. Now I\'m trying to make it a UIPickerViewDelegate

Answer 1

Fix-it in XCode 8.1 inserts a deprecated version of the method below if you're using Swift 3:

func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
    return componentNumber
}

In XCode 10.0+

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return componentNumber
}
