How can I sort this Array in Swift 3 ? ( Picker View ) ( Core Data )

Question

How can I sort this Array in my PickerView ? I am using Swift 3.

Answer 1

Instead of sorting array every time in titleForRow you need to sort it once after you initialized your stores array.

stores.sort { $0.name < $1.name }

Now stores array is sorted by name property now simply return the name from titleForRow method.

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
}

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return stores.count
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return stores[row].name
}

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    print(stores[row].name)
}
