A simple date picker written in Swift, that has two wheels for year selection and an era picker. Supports Gregorian calender only by now.

Features:

• Year, Month, Century, Subcentury and Era picker wheels
• 'Infinite' scrolling for Year, Month, Century, Subcentury and Era
• Minimum and maximum year customization in range from 9999 DCE to 9999 CE
• Date validation (incl. vs maximum and minimum date)
• Different color for valid / non-valid date font

Just copy XKDatePickerView.swift to your project. UIPickerViewDataSource and UIPickerViewDelegate protocols are already implemented in AXDatePickerView itself, so don't implement them for axDatePickeView object, Add conformance to XKDatePickerViewDelegate instead. Example:

class ViewController: UIViewController, XKDatePickerViewDelegate {

override func viewDidLoad() {
        super.viewDidLoad()
        xkDatePicker.xkDatePickerDelegate = self
        }

Implement XKDatePickerViewDelegate function to recieve selected date:

func axDatePickerDateChangedWith(date: Date) {
        // Your code here to handle date
    }

Make outlet for AXDatePicker object in your controller.

@IBOutlet weak var xkDatePicker: XKDatePickerView!

To select date implement xkDatePickerDateChangedWith function:

func xkDatePickerDateChangedWith(date: Date) {
        // Your code here to handle the date
    }

To change minimum and maximum year set corresponing class property:

let minYear: Int = -4000
xkDatePicker.minimumYear = minYear

let maxYear: Int = 5500
xkDatePicker.maximumYear = maxYear

New dates will be handled automatically at runtime. Keep in mind, that maximum date should be greater than minimum date, otherwise a fatalError will be thrown.

Color for valid and invalid dates use validDateFontColor and invalidDateFontColor properties (handled automatically at runtime):

let balack = UIColor.black()
xkDatePicker.validDateFontColor = balack

let red = UIColor.red()
xkDatePicker.invalidDateFontColor = red
