IOS UIWebView leaked

Question

class MyViewController: UIViewController {
     @IBOutlet weak var webView: UIWebView?
     override func viewDidLoad() {
    super.viewDidLoad()

    let url = NSURL(string: urlString)
    let request = NSURLRequest(URL: url!)
    SVProgressHUD.show()

    webView?.loadRequest(request)
    webView?.scrollView.header = MJRefreshNormalHeader(refreshingBlock: {

      [weak self] in
      if let strongSelf = self {
        strongSelf.webView?.reload()
      }})   }
     override func viewDidDisappear(animated: Bool) {
    super.viewDidDisappear(animated) 

    SVProgressHUD.dismiss()   }    }

extension MyViewController: UIWebViewDelegate {
     func webViewDidFinishLoad(webView: UIWebView) {
    webView.scrollView.header.endRefreshing()
    SVProgressHUD.dismiss()   }       func webView(webView: UIWebView, didFailLoadWithError error: NSError?) {
    webView.scrollView.header.endRefreshing()
    SVProgressHUD.dismiss()   }    }

The view controller was pressed by the navigation controller, when I pop it up, I have leaks. In instrument.Leak, I saw them.

I am sure that webView, myViewController were delayed, but when pop pop myViewController, 4M increased and was not released. Please help and thanks.

According to the answer posted here , there is a workaround that if you install configuration.selectionGranularityon WKSelectionGranularityCharacter, then the leak will stop:

let config = WKWebViewConfiguration()
config.selectionGranularity = .character //WKSelectionGranularityCharacter
let myWebview = WKWebview(frame: frame, configuration: config)
