SwiftUI check if URL is reachable and switch to ContentView automaticly - swiftui

Question

I tried this to check the status of connectivity :
func checkConnection() {
if let url = URL(string: "https://www.xxxxxxxxxxxxxxxxxxxxx") {
var request = URLRequest(url: url)
request.httpMethod = "HEAD"
URLSession(configuration: .default)
.dataTask(with: request) { (_, response, error) -> Void in
guard error == nil else {
print("Error:", error ?? "")
return
}
guard (response as? HTTPURLResponse)?
.statusCode == 200 else {
print("down")
return
}
print("up")
}
.resume()
}
}
and it works fine. It shows "up" or "down" in console. I'm a beginner in Xcode and SwiftUI, so my question is:
Instead of print("up") I want to go automaticly to the "ContentView" if URL is reachable. I tried ContentView() but it does not work.
Thanks for your help.

This is easily handled with a NavigationLink. One method to do this is by doing the following.
Add a binding to keep state for if the view is active.
Add navigation link to present the view that you want.
Check your conditions returning true/false
If condition is true, the bound state will update the NavigationLink and view will be presented.
#State var isValidURL = false
//Body {...
NavigationLink(destination: ContentView(), isActive: isValidURL {}
func checkConnection() {
if let url = URL(string: "https://www.xxxxxxxxxxxxxxxxxxxxx") {
var request = URLRequest(url: url)
request.httpMethod = "HEAD"
URLSession(configuration: .default)
.dataTask(with: request) { (_, response, error) -> Void in
guard error == nil else {
print("Error:", error ?? "")
return
}
guard (response as? HTTPURLResponse)?
.statusCode == 200 else {
print("down")
return
}
self.isValidURL.toggle()
}
.resume()
}
}
