Thank you for your feedback. Unfortunately, this does not solve my problem. The function is supposed to be applicable for all possible (like UnitArea, UnitAcceleration, UnitAngle, ...). I wrote the following function which returns me the desired result as string. func showMeasurement(value: Double, unit: String, symbol: Bool) -> String {         switch(unit) {             //MARK: Aceleration         case "UnitAcceleration.metersPerSecondSquared":             let newValue = Measurement(value: value, unit: UnitAcceleration.metersPerSecondSquared)             if symbol {                 return newValue.unit.symbol             } else {                 return newValue.formatted(.measurement(width: .narrow, usage: .asProvided, numberFormatStyle: .number.precision(.fractionLength(2))))             }         case "UnitAcceleration.UnitAcceleration":             let newValue = Measurement(value: value, unit: UnitAcceleration.baseUnit())             if symbol {                 return newValue.unit.symbol             } else {                 return newValue.formatted(.measurement(width: .narrow, usage: .asProvided, numberFormatStyle: .number.precision(.fractionLength(2))))             } .... But later I will also need the corresponding Measurment to be able to calculate with the values.

Try ``struct ExampleView: View { var fruits = ["Banana","Apple", "Peach", "Watermelon", "Grapes" ] @State private var selectedFruit = 0 var body: some View { VStack { Form { Picker(selection: $selectedFruit, label: Text("Select Favorite Fruit")) { ForEach(0..<fruits.count) { Text(self.fruits[$0]) } } Text("Your Favorite Fruit: \(self.fruits[selectedFruit])") } .pickerStyle(MenuPickerStyle()) } } }
