问题
I am using firebase Deeplink URL to open my app's specific section. It is working well when app running in background but when I killed the app and click deeplink url from outside than I don't know how to handle that case, I mean where I should write my condition to get the parameters of url.
This method of app delegate called when app in background
@available(iOS 8.0, *)
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
guard let dynamicLinks = DynamicLinks.dynamicLinks() else {
return false
}
let handled = dynamicLinks.handleUniversalLink(userActivity.webpageURL!) { (dynamiclink, error) in
if let dynamicLink = dynamiclink, let _ = dynamicLink.url
{
var path = dynamiclink?.url?.path
path?.remove(at: (path?.startIndex)!)
let delimiter = "/"
var fullNameArr = path?.components(separatedBy: delimiter)
let type: String = fullNameArr![0]
let Id: String? = (fullNameArr?.count)! > 1 ? fullNameArr?[1] : nil
if(type == "games")
{
self.callGameDetailView(gameId: Id! , gameType: "created", notificationId: "NIL" )
}else{
var paths = dynamicLink.url?.path
paths?.remove(at: (path?.startIndex)!)
self.setRewardViewController(paths!)
}
} else {
// Check for errors
}
}
return handled
}
but it will not call open url method when I killed the app and hit the dynamic link url:
@available(iOS 9.0, *)
func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])
-> Bool {
return self.application(application, open: url, sourceApplication: nil, annotation: [:])
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
let dynamicLink = DynamicLinks.dynamicLinks()?.dynamicLink(fromCustomSchemeURL: url)
if let dynamicLink = dynamicLink
{
var path = dynamicLink.url?.path
path?.remove(at: (path?.startIndex)!)
let delimiter = "/"
var fullNameArr = path?.components(separatedBy: delimiter)
let type: String = fullNameArr![0]
let Id: String? = (fullNameArr?.count)! > 1 ? fullNameArr?[1] : nil
if(type == "games")
{
self.callGameDetailView(gameId: Id! , gameType: "created", notificationId: "NIL" )
}else{
var paths = dynamicLink.url?.path
paths?.remove(at: (path?.startIndex)!)
self.setRewardViewController(paths!)
return true
}
}
return FBSDKApplicationDelegate.sharedInstance().application(
application,
open: url,
sourceApplication: sourceApplication,
annotation: annotation)
}
In short I have no Idea how to handle the dynamic link when app runs first time or run after killing the app?

I also have same issue, you need to get NSUserActivity from launchOptions
var launchURL :URL? = nil
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
....
// this code should have worked but not working for me with Xcode 9
// if let userActivityDictionary = launchOptions?[.userActivityDictionary] as? [UIApplicationLaunchOptionsKey : Any],
// let auserActivity = userActivityDictionary[.userActivityType] as? NSUserActivity {
// launchURL = auserActivity.webpageURL
// }
if let userActDic = launchOptions?[UIApplicationLaunchOptionsKey.userActivityDictionary] as? [String: Any],
let auserActivity = userActDic["UIApplicationLaunchOptionsUserActivityKey"] as? NSUserActivity{
NSLog("type \(userActDic.self),\(userActDic)") // using NSLog for logging as print did not log to my 'Device and Simulator' logs
launchURL = auserActivity.webpageURL
}
...
}
func applicationDidBecomeActive(_ application: UIApplication) {
if let url = self.launchURL {
self.launchURL = nil
DispatchQueue.main.asyncAfter(deadline: .now()+2.0, execute: {
// wait to initalize notifications
if let dynamicLinks = DynamicLinks.dynamicLinks() {
NSLog("handling \(dynamicLinks)")
dynamicLinks.handleUniversalLink(url) { (dynamiclink, error) in
if let link = dynamiclink?.url {
NSLog("proceessing \(dynamicLinks)")
let strongMatch = dynamiclink?.matchConfidence == .strong
// process dynamic link here
self.processDynamicLink(withUrl: link, andStrongMatch: strongMatch)
}
}
}
})
}
}

The two openURL AppDelegate methods that you are referencing are called when the application is opened by use of a URI scheme. URI scheme functionality will only work in very specific scenarios. In iOS 9, Apple switched to Universal Links, which actually call the function application:continueUserActivity:restorationHandler:.
This function does not call the openURL methods so all of your Universal links handling will have to be done in the continueUserActivity that you mentioned first.
For the sake of saving yourself a lot of trouble in handling other edgecases, I'd suggest moving to another 3rd party provider like Branch (Full disclosure, I work there) since they bundle all of this handling into one callback and provide more functionality and attribution related services that are not available to Firebase users.

In application:didFinishLaunchingWithOptions: method, you need to register your customURLScheme.
FirebaseOptions.defaultOptions()?.deepLinkURLScheme = YOUR_URL_SCHEME
