{
    "xdm:activityId":"xcore:offer-activity:xxxxxxxxxxxxxxx",
    "xdm:placementId":"xcore:offer-placement:xxxxxxxxxxxxxxx"
}

In Xcode, ensure that AEP Optimize is added to the list of packages in Package Dependencies. See Swift Package Manager.

Navigate to Luma > Luma > AppDelegate in the Xcode Project navigator.

Ensure AEPOptimize is part of your list of imports.

import AEPOptimize

Ensure Optimize.self is part of the array of extensions that you are registering.

let extensions = [
    AEPIdentity.Identity.self,
    Lifecycle.self,
    Signal.self,
    Edge.self,
    AEPEdgeIdentity.Identity.self,
    Consent.self,
    UserProfile.self,
    Places.self,
    Messaging.self,
    Optimize.self,
    Assurance.self
]

Navigate to Luma > Luma > Model > Data > decisions in the Xcode Project navigator. Update the activityId and placementId values with the decision scope details you copied from the Journey Optimizer interface.

Navigate to Luma > Luma > Utils > MobileSDK in the Xcode Project navigator. Find the func updatePropositionOD(ecid: String, activityId: String, placementId: String, itemCount: Int) async function. Add the following code:

// set up the XDM dictionary, define decision scope and call update proposition API
Task {
   let ecid = ["ECID" : ["id" : ecid, "primary" : true] as [String : Any]]
   let identityMap = ["identityMap" : ecid]
   let xdmData = ["xdm" : identityMap]
   let decisionScope = DecisionScope(activityId: activityId, placementId: placementId, itemCount: UInt(itemCount))
   Optimize.clearCachedPropositions()
   Optimize.updatePropositions(for: [decisionScope], withXdm: xdmData)
}

This function:

• sets up an XDM dictionary xdmData, containing the ECID to identify the profile for which you have to present the offers.

• defines decisionScope, an object that is based on the decision you have defined in the Journey Optimizer - Decision Management interface and is defined using the copied decision scope from Create a decision. The Luma app uses a configuration file (decisions.json) that retrieves the scope parameters, based on the following JSON format:

  code language-swift
  "scopes": [ { "name": "name of the scope", "activityId": "xcore:offer-activity:xxxxxxxxxxxxxxx", "placementId": "xcore:offer-placement:xxxxxxxxxxxxxxx", "itemCount": 2 } ]

  However, you can use any kind of implementation to ensure the Optimize APIs get the proper parameters (activityId, placementId and, itemCount), to construct a valid DecisionScope object for your implementation.
  For your information: the other key-values in the decisions.json file are for future use and not relevant and used currently in this lesson and as as part of the tutorial.

• calls two APIs: Optimize.clearCachePropositions and Optimize.updatePropositions. These functions clear any cached propositions and update the propositions for this profile.

Navigate to Luma > Luma > Views > Personalization > EdgeOffersView in the Xcode Project navigator. Find the func onPropositionsUpdateOD(activityId: String, placementId: String, itemCount: Int) async function and inspect the code of this function. The most important part of this function is the Optimize.onPropositionsUpdate API call, which

• retrieves the propositions for the current profile based on the decision scope (which you have defined in Journey Optimizer - Decision Management),
• retrieves the offer from the proposition,
• unwraps the content of the offer so it can be displayed properly in the app, and
• triggers the displayed() action on the offer which sends an event back to the Edge Network informing the offer is displayed.

Still in EdgeOffersView, add the following code to the .onFirstAppear modifier. This code ensures that the callback for updating the offers is registered only once.

// Invoke callback for offer updates
Task {
    await self.onPropositionsUpdateOD(activityId: decision.activityId, placementId: decision.placementId, itemCount: decision.itemCount)
}

Still in EdgeOffersView, add the following code to the .task modifier. This code updates the offers when the view is refreshed.

// Clear and update offers
await self.updatePropositionsOD(ecid: currentEcid, activityId: decision.activityId, placementId: decision.placementId, itemCount: decision.itemCount)

Rebuild and run the app in the simulator or on a physical device from Xcode, using .

Go to the Personalisation tab.

Select Edge Personalisation.

Scroll to the top, and you see two random offers displayed from the collection that you have defined in the DECISION LUMA - MOBILE APP DECISION tile.

{width="300"}

The offers are random, as you have given all offers the same priority and the ranking for the decision is based on priority.

Review the setup instructions section to connect your simulator or device to Assurance.
