Universal links - Unregistered XPC Activity: com.apple.SharedWebCredentials.recheck - ios11

Question

I am trying to implement the universal link for my domain in Xcode9. The teamID and bundle identifier for debug/inhouse are different from release build. And I am testing the debug version on real device. Kinda stuck here. Any help would be really appreciated. Thanks.
I have uploaded the unsigned apple-app-site-association file to myDomain/.well-known/ folder, and the type is application/json. The file could be returned when using curl -v myDomain/.well-known/AASA as below:
{
"webcredentials": {
"apps": [
"TeamID.BundleIdentifier"
]
},
"applnks": {
"apps": [],
"details": [
{
"appID": "TeamID.BundleIdentifier",
"paths": [
"*"
]
}
]
}
}
In myDomain server header, I have added the following line
<meta name="apple-itunes-app" content="app-id=App_Store_ID">
The associate domain was also turned on and added applinks:myDomain under the capabilities in Xcode
Following code has been added to appDelegate:
/* universal links */
public func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: #escaping ([Any]?) -> Swift.Void) -> Bool {
// 1
NSLog("Continue User Activity called: ")
if userActivity.activityType == NSUserActivityTypeBrowsingWeb {
let webURL = userActivity.webpageURL!
if !present(URL: webURL as NSURL) {
application.openURL(webURL)
}
}
return true
}
Deleted my App and safari websiteData on iPhone7. Run the project on my phone, following is the console log:

My questions are:
1. I added https://myDomain in notes, long press the url, it shows open link but no open in app option. what should I do to bring up the "open in app" option when long pressing?
Long press the url, choose open, it opens in safari. The smart banner in safari only points to apple store, as if safari never knows that the debug version has already installed on the phone. How can safari knows that debug version is installed hence it should show "open" in the smart banner?
when clicking on the url, universal Link method in appDelegate wasn't called. Any settings not set correctly?
There's an error in following line in the device console log. Also from the device console log, can we conclude that requesting apple-app-site-association file succeeded?

Thanks very much.
