NSUserActivity vs. Core Spotlight deep link - ios

Question

I am using both NSUserActivity and Core Spotlight to index content on my app.
The reason I am using Core Spotlight is because I want to index this content before the user access (opens) it.
The problem I am facing is in the AppDelegate method:
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: #escaping ([Any]?) -> Void) -> Bool
Basically userActivity ONLY contains the correct information when I do this in my viewController:
userActivity = myUserActivity
But it does not work if I do:
CSSearchableIndex.default().indexSearchableItems(searchableItems).
By using the second method (Core Spotlight) I can see all my results in spotlight search, but when I tap the item, I don't have any information in the AppDelegate method.
The worst part is this:
po userActivity.activityType
"com.apple.corespotlightitem"
If I print the activityType, instead of getting my own, I get this one...
Any suggestions?

When your app is launched from a CoreSpotlight result you get a CSSearchableItemActionType.
You need to handle this type of action by retrieving the CSSearchableItemActivityIdentifier - This value will match the identifier you provided for your searchable item when you submitted it to the index.
Something like:
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: #escaping ([Any]?) -> Void) -> Bool {
if userActivity.activityType == CSSearchableItemActionType {
guard let selectedItem = userActivity.userInfo?[CSSearchableItemActivityIdentifier] as? String else {
return
}
// Do something with selectedItem
}
}
