        func numberOfComponents( in pickerview: UIPickerView) -> Int {

             

                pickerJahrgang.tag = 0

                pickerTestjahr.tag = 1

                pickerSprint.tag = 2

                pickerKilmmhang.tag = 3

                picker1000m.tag = 4

              

              

                if pickerJahrgang.tag == 0 {return 1}

                if pickerSprint.tag == 1 {return 3}

                if pickerTestjahr.tag == 2 {return 1}

                if pickerKilmmhang.tag == 3 {return 2}

                if picker1000m.tag == 4 {return 3}

             else  {

              

                return 1

                }

          Try to define "numberOfComponents" for more than one Picker in one UIView?

          I presume you mean in “one UIViewController” here.  That is, your view controller implements the picker data source protocol (UIPickerViewDataSource) and you want it to return different results for different pickers.

          You could do that by switching based on the view (or, as you’ve shown, the view tag) but I’d do it by creating a small class that acts as the picker data source and then instantiate that class multiple times, once for each of my pickers.
