following code

var webView: WKWebView!
override func loadView() {
 super.loadView()
 self.webView = WKWebView(frame: .zero)
 view = webView
}
override func viewDidLoad() {
 super.viewDidLoad()
 
 var request = URLRequest(url: URL(string: "https://hosts")!)
 request.httpMethod = "POST"
 let bodyData = "data1=postData"
 request.httpBody = bodyData.data(using: .utf8)!
 self.webView.load(request)
}

POST parameters are passed in iOS 11.2, but POST parameters are not passed in iOS 11.3.

Anyone please give me the answer.

 super.loadView()
 self.webView = WKWebView(frame: .zero)
 view = webView
}
override func viewDidLoad() {

 request.httpMethod = "POST"
 let bodyData = "data1=postData"
 request.httpBody = bodyData.data(using: .utf8)!
 self.webView.load(request)
}

I was able to get the POST parameter on Web site loaded on iOS 11.2, but could not get it on iOS 11.3

Why did not get it on iOS 11.3? Was the specification changed?

I want anyone to tell me the workaround. Please give me the answer.
