Register multiple Siri shortcut at once

Question

I wrote some code which try to register multiple Siri shortcut at once by iterating enum values

When I run the code and open settings app, it only shows the last registered shortcut.

How should I register multiple Siri shortcut at once?

static func registerSiriShortcut(to responder: UIResponder) {

    if #available(iOS 12.0, *) {
      let cases = SiriShortcutType.allCases
      for type in cases {

        let activity = NSUserActivity(activityType: type.siriActivityType)
        activity.title = type.siriShortcutTitle
        activity.isEligibleForSearch = true
        activity.isEligibleForPrediction = true

        responder.userActivity = activity
        responder.userActivity?.becomeCurrent()
      }
    }

  }

Answer 1

Your code seems okay to me. Generally, Settings->Siri shows only the recent registered shortcuts. If you go to Settings->Siri->All shortcuts, you will see the all names there.

As you mention in your code activity.isEligibleForSearch = true Alternatively, go to your phone search from swipe right from home and type the shortcut, you should see the shortcut item's popup too.

EDIT 1: Proof of my Code:

1. Info.plist: You need to mention how many NSUserActivityTypes:

   <Key>NSUserActivityTypes</key>
   <array> 
   <string>com.rio.SiriShortcuts.makeGreen</string>
   <string>com.rio.SiriShortcuts.makeRed</string>
   </array>
   

2. Enum class:

   enum SiriShortcutType {
   case makeRed
   case makeGreen
   
   var siriActivityType: String {
       switch self {
           case .makeRed:
           return "com.rio.SiriShortcuts.makeRed"
           case .makeGreen:
           return "com.rio.SiriShortcuts.makeGreen"
       }
   }
   
   var siriShortcutTitle: String {
       switch self {
       case .makeRed:
           return "Make View Red"
       case .makeGreen:
           return "Make View Green"
       }
   }
   
   var color: String {
       switch self {
       case .makeRed:
           return "red"
       case .makeGreen:
           return "green"
       }
   }
   
   static let allCases:[SiriShortcutType] = [.makeRed, .makeGreen]
   }
   

3. Now my register method in VC (called by button action):

    func registerSiriShortcut() {
   if #available(iOS 12.0, *) {
       let cases = SiriShortcutType.allCases
       var suggestions: [INShortcut] = []
       for type in cases {
   
           let activity = NSUserActivity(activityType: type.siriActivityType)
           activity.userInfo = ["color" : type.color]
           activity.title = type.siriShortcutTitle
           activity.isEligibleForSearch = true
           activity.isEligibleForPrediction = true
           activity.persistentIdentifier = NSUserActivityPersistentIdentifier(type.siriActivityType)
           suggestions.append(INShortcut(userActivity: activity))
       }
       INVoiceShortcutCenter.shared.setShortcutSuggestions(suggestions)
   }
   }
   

Edit 1: INShortcut supports multiple Siri Shortcuts: See the updated registerSiriShortcut().
