I'm adding Siri Shortcuts to my app using INUIAddVoiceShortcutViewController and things are working fine, except when I try to delete a shortcut using NSUserActivity.deleteSavedUserActivities(withPersistentIdentifiers:)

I verified the persistentIdentifier is not being saved for the NSUserActivity. Below is the code that I used to create the NSUserActivity:
func createUserActivityForShortcut(workoutName: String, timerID: String) -> NSUserActivity? {  

    let userActivity = NSUserActivity(activityType: "com.fourthframe.intervals.start-timer")  
    userActivity.isEligibleForSearch = true  

    userActivity.isEligibleForPrediction = true  
    userActivity.suggestedInvocationPhrase = "Start \(workoutName)"  

    userActivity.title = "Start \(workoutName)"  
    userActivity.userInfo = ["timerID": timerID]  
    userActivity.persistentIdentifier = timerID  
    userActivity.needsSave = true  
    userActivity.requiredUserInfoKeys = ["timerID"]  
    userActivity.becomeCurrent()  

    return userActivity  

} 

Steps to Reproduce:
1) Create NSUserActivity
2) Add a voice shortcut using INUIAddVoiceShortcutViewController
3) Retrieve list of voice shortcuts using INVoiceShortcutCenter.shared.getAllVoiceShortcuts
4) Verify that voiceShortcut.shortcut.userActivity?.persistentIdentifier is nil

Expected Results:
voiceShortcut.shortcut.userActivity?.persistentIdentifier is not nil

Actual Results:
voiceShortcut.shortcut.userActivity?.persistentIdentifier is nil

Version:
iOS 12.1

Notes:
I’ve had others on stackoverflow and dev forum confirm this behavior
