DataSource and Delegate aren't called

[anirudhamahale]

I created swift 3 project and ran pod install with ANDLineChartView (0.2.2) and implemented the DataSource and Delegate methods, Setting the DataSource and Delegate in ViewDidLoad but the methods associating with the DataSource and Delegate aren't called.

I can't reproduce it. Here is an example UIViewController that I created today. Please try this in you project and let me know if you still have any issues.

import UIKit
import ANDLineChartView

class ViewController: UIViewController {
    lazy var chartView: ANDLineChartView = {
        let chartView = ANDLineChartView(frame: CGRect(origin: .zero, size: self.view.bounds.size))
        chartView.delegate = self
        chartView.dataSource = self
        return chartView
    }()
    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.addSubview(self.chartView)
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}
extension ViewController: ANDLineChartViewDelegate {
    
}
extension ViewController: ANDLineChartViewDataSource {
    func numberOfElements(in chartView: ANDLineChartView!) -> UInt {
        return 10
    }
    func numberOfGridIntervals(in chartView: ANDLineChartView!) -> UInt {
        return 6
    }
    func chartView(_ chartView: ANDLineChartView!, valueForElementAtRow row: UInt) -> CGFloat {
        return CGFloat(row) * 2.0
    }
    func chartView(_ chartView: ANDLineChartView!, descriptionForGridIntervalValue interval: CGFloat) -> String! {
        return "\(interval)"
    }
    func maxValueForGridInterval(in chartView: ANDLineChartView!) -> CGFloat {
        return 30
    }
    func minValueForGridInterval(in chartView: ANDLineChartView!) -> CGFloat {
        return -4
    }
}
