Describe the bug

• App Crashes when the component gets rendered DatePickerIOS on IOS 16 Devices and Simulator

Expected behavior

• DatePickerIOS should render as expected on all iOS versions

To Reproduce

export default class App extends Component {

  state = { date: new Date() }

  render = () =>
    <DatePicker
      date={this.state.date}
      onDateChange={date => this.setState({ date })}
      mode={"date"}
      locale={'en'}
      style={{
            width: Dimensions.get('window').width,
            height: Dimensions.get('window').height / 3,
            backgroundColor: '#FFF',
          }}
      textColor={'#000000'}
    />

}

Smartphone (please complete the following information):

• OS: iOS v16.x.x only

• react-native-date-picker version [5.0.0]

Workaround

• If you are using RN > 0.72 and later
• Check if the date-picker crashes or not. If crashed, try this workaround.
• Go to iOS folder > DatePicker.m > Replace setup function

-(void)setup {
    if(@available(iOS 13, *)) {
        self.overrideUserInterfaceStyle = UIUserInterfaceStyleLight;
    }
    if (@available(iOS 13, *)) {
        self.preferredDatePickerStyle = UIDatePickerStyleInline; // it will use "Calendar" style date picker for iOS v13 to v16
    } 
    if (@available(iOS 17, *)) {
        self.preferredDatePickerStyle = UIDatePickerStyleWheels; // // it will use traditional (rolling wheels) style date picker for iOS v17 and later
    }
    self.calendar = [NSCalendar calendarWithIdentifier:NSCalendarIdentifierGregorian];
}

I just had this happen in my EXPO app, on iOS. I was selecting the year, and when the spinner stopped, the app crashed. All I can see in Sentry is NSInternalInconsistencyException: UITableView dataSource is not set:

{
beingPresented: true,
is_window_rootViewController: false,
presentingViewController: UIViewController,
screen: RCTModalHostViewController,
window: <UIWindow: 0x10130b960; frame = (0 0; 375 812); autoresize = W+H; gestureRecognizers = <NSArray: 0x2809cbe70>; layer = <UIWindowLayer: 0x2809cb780>>,
window_isKeyWindow: true,
window_windowLevel: 0.000000
}

I've never reproduced it locally but it happened in release mode. Seems like it happens the first time you try to use it, then it doesn't happen again.
