I am new to swift, so any advice would be appreciated. So the I have seen URL and URLSession return a timeout response, the android varient of my app does not show this issue.
class HasInternet: ObservableObject {
let monitor = NWPathMonitor()
let queue = DispatchQueue(label: "Monitor")
private var status: NWPath.Status = .requiresConnection
@Published var isConnected = false
init(){
monitor.pathUpdateHandler = { [weak self] path in
if let url = URL(string: "https://google.com") {
var request = URLRequest(url: url)
request.httpMethod = "HEAD"
request.timeoutInterval = 30
let sessionConfig = URLSessionConfiguration.default
sessionConfig.timeoutIntervalForRequest = 30.0
sessionConfig.timeoutIntervalForResource = 60.0
URLSession(configuration: sessionConfig)
.dataTask(with: request) { (_, response, error) -> Void in
guard error == nil else {
return
}
guard (response as? HTTPURLResponse)?
.statusCode == 200 else { return }
DispatchQueue.main.async {
self?.isConnected = true
}
}
.resume()
}
}
monitor.start(queue: queue)
}
}
Here is another place with the same behaviour.
func post(dModel: DialogModel? = nil, url: String, type: responseTypes, body: [String: Any], headers: [headerType], async: Bool = true) { //async
let semaphore = DispatchSemaphore(value: 0)
let timeout: TimeInterval = 10
if let url = URL(string: url) {
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.timeoutInterval = 30
for header in headers {
request.setValue(header.value, forHTTPHeaderField: header.key)
}
do {
request.httpBody = try JSONSerialization.data(withJSONObject: body, options: .prettyPrinted)
} catch let error {
self.processError(dModel: dModel, error: error.localizedDescription, type: .report)
return
}
let sessionConfig = URLSessionConfiguration.default
sessionConfig.timeoutIntervalForRequest = 30.0
sessionConfig.timeoutIntervalForResource = 60.0
URLSession(configuration: sessionConfig)
.dataTask(with: request) { (data, response, error) -> Void in
if let error = error {
self.processError(dModel: dModel, error: error.localizedDescription, type: .report)
if(async){
semaphore.signal() // Signal semaphore even in case of error
}
return
}
if let httpResponse = response as? HTTPURLResponse{
if let unWrappedData = data {
if let httpResponseData = String(data: unWrappedData, encoding: .utf8) {
self.parse(dModel: dModel, type: type, response: httpResponseData, statusCode: httpResponse.statusCode)
}
}
} else {
self.processError(error: "Invalid response")
}
if(async){
semaphore.signal() // Signal semaphore after processing the response
}
}
.resume()
if(async){
semaphore.wait(timeout: .now() + timeout)
}
} else {
processError(error: "Invalid URL")
}
}

I am using a WKWebView to load a webpage and a UITextFiled as the address bar. If I select the UITextField and try to click out of it on to the webView my app crashes. Only happens after textField has been selected. I can navigate other buttons fine. I feel its something obvious but I am new to Swift.
