URL not being passed to appdelegate - swift

Question

I can't get dynamic links or universal links working. My app won't read in a URL. I've started with a fresh project, added a URL Scheme of com.company.AppLoginView and the below code into AppDelegate. I added a url in notes of: com.company.AppLoginView://Register?User=Name. Clicking the link requests to open the app which then opens. However, nothing seems to be passed to the app and the below isn't being called. What am I doing wrong? This is a completely empty app and should work.
func application(_ app: UIApplication, open url: URL,
options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
if let scheme = url.scheme,
scheme.localizedCaseInsensitiveCompare("com.myApp") == .orderedSame,
let view = url.host {
var parameters: [String: String] = [:]
URLComponents(url: url, resolvingAgainstBaseURL: false)?.queryItems?.forEach {
parameters[$0.name] = $0.value
}
print("View:\(view) Params:\(parameters) Scheme:\(scheme)")
// redirect(to: view, with: parameters)
}
return true
}

Answer 1

This is because target is iOS 13 and SceneDelegate takes over some functions from AppDelegate. In particular, open:url is replaced by SceneDelegate scene:openURLContexts.

You should add ULR scheme and URL identifier to plist. You can use this:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Editor</string>
<key>CFBundleURLName</key>
<string>com.company.AppLoginView</string>
<key>CFBundleURLSchemes</key>
<array>
<string>com.company.AppLoginView</string>
</array>
</dict>
</array>
and check it with print in method in AppDelegate
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
print(url)
return true
}
open Safari and type your address
com.company.AppLoginView://Register?User=Name
