SwiftWarplyFramework Migration Plan


Overview

This document outlines the plan for migrating the Objective-C components of SwiftWarplyFramework to Swift. The UI components (ViewControllers and Cells) are already in Swift and will not be modified.


Layer Consolidation Details

This section details the specific steps for consolidating swiftApi.swift, MyApi.h/m, and Warply.h/m into a single WarplySDK.swift implementation.


Current Structure Analysis


swiftApi.swift: Swift class with API operations, data models, and global state management

MyApi.h/MyApi.m: Objective-C bridging layer that interfaces with core Warply functionality

Warply.h/Warply.m: Core Objective-C implementation with networking, managers, and SDK functionality


Consolidation Strategy

Replace all three layers with a modern Swift implementation that:


Eliminates the unnecessary bridging layer (MyApi)
Modernizes the architecture using Swift features
Properly separates concerns (models, networking, state management)
Implements async/await patterns
Uses proper Swift error handling


Detailed Migration Steps


Step 1: Model Extraction (from swiftApi.swift)


 Create Models/ directory structure

 Move to Models/Campaign.swift:


 CampaignItemModel → Campaign

 LoyaltyContextualOfferModel → LoyaltyOffer


 Move to Models/Coupon.swift:


 CouponItemModel → Coupon

 CouponSetItemModel → CouponSet

 RedeemedMerchantDetailsModel → RedeemedMerchantDetails


 Move to Models/Market.swift:


 MarketPassDetailsModel → MarketPass

 SupermarketModel → Supermarket


 Move to Models/Merchant.swift:


 MerchantModel → Merchant

 ShopAvailabilityItemModel → ShopAvailability


 Move to Models/Events.swift:


 LoyaltySDKFirebaseEventModel → FirebaseEvent

 LoyaltySDKDynatraceEventModel → DynatraceEvent

 LoyaltySDKSessionExpiredEventModel → SessionExpiredEvent

 CouponEventModel → CouponEvent


 Move to Models/Response.swift:


 VerifyTicketResponseModel → VerifyTicketResponse

 GenericResponseModel → GenericResponse

 RedeemedSMHistoryModel → RedeemedSMHistory


 Move to Models/Gifts.swift:


 LoyaltyGiftsForYouPackage → LoyaltyGift

 WarplyCCMSEnabledModel → CCMSEnabled


Step 2: Global State Migration (from swiftApi.swift GlobalVariables)


 Create Core/SDKState.swift:

private final class SDKState {
  static let shared = SDKState()

  var campaigns: [Campaign] = []
  var coupons: [Coupon] = []
  var oldCoupons: [Coupon] = []
  var allOldCoupons: [Coupon] = []
  var couponSets: [CouponSet] = []
  var ccmsCampaigns: [LoyaltyOffer] = []
  var seasonalList: [LoyaltyGift] = []
  var merchants: [Merchant] = []
  var carouselList: [Campaign] = []
  var marketPassDetails: MarketPass?
  var supermarketCampaign: Campaign?
}


Step 3: UserDefaults Migration (from swiftApi.swift)


 Create Storage/UserDefaultsStore.swift:

@propertyWrapper
struct UserDefault<T> {
  let key: String
  let defaultValue: T

  var wrappedValue: T {
      get { UserDefaults.standard.object(forKey: key) as? T ?? defaultValue }
      set { UserDefaults.standard.set(newValue, forKey: key) }
  }
}


final class UserDefaultsStore {
      @UserDefault(key: "trackersEnabled", defaultValue: false)
      var trackersEnabled: Bool

  @UserDefault(key: "appUuidUD", defaultValue: "")
  var appUuid: String

  @UserDefault(key: "merchantIdUD", defaultValue: "")
  var merchantId: String

  @UserDefault(key: "languageUD", defaultValue: "el")
  var applicationLocale: String

  @UserDefault(key: "isDarkModeEnabledUD", defaultValue: false)
  var isDarkModeEnabled: Bool


}


#### Step 4: Network Layer Implementation (replacing MyApi methods)
- [ ] Create Network/Endpoints.swift:
  ```swift
  enum Endpoint {
      case verifyTicket(guid: String, ticket: String)
      case getCoupons(language: String, couponsetType: String)
      case getCampaigns(language: String, filters: [String: Any])
      case getCampaignsPersonalized(language: String, filters: [String: Any])
      case getMerchants(categories: [String], defaultShown: Bool, center: Double, tags: [String], uuid: String, distance: Int, parentUuids: [String])
      case getCouponSets(active: Bool, visible: Bool, uuids: [String]?)
      case getAvailableCoupons
      case getMarketPassDetails
      case getCosmoteUser(guid: String)
      case getSingleCampaign(sessionUuid: String)
      case logout

      var path: String { /* implementation */ }
      var method: HTTPMethod { /* implementation */ }
      var parameters: [String: Any]? { /* implementation */ }
  }


 Create Network/NetworkService.swift:
```swift
protocol NetworkServiceProtocol {
  func request(_ endpoint: Endpoint) async throws -> T
  func upload(_ data: Data, to endpoint: Endpoint) async throws
  func download(from endpoint: Endpoint) async throws -> Data
}


final class NetworkService: NetworkServiceProtocol {
      private let session: URLSession
      private let baseURL: String

  func request<T: Decodable>(_ endpoint: Endpoint) async throws -> T
  func upload(_ data: Data, to endpoint: Endpoint) async throws
  func download(from endpoint: Endpoint) async throws -> Data


}


#### Step 5: Configuration Migration (from WLGlobals.h and swiftApi)
- [ ] Create Core/Configuration.swift:
  ```swift
  public struct Configuration {
      static var baseURL: String = ""
      static var host: String = ""
      static var errorDomain: String = ""
      static var merchantId: String = ""
      static var language: String = "el"
      static var verifyURL: String = ""

      enum Environment {
          case development
          case production

          var baseURL: String {
              switch self {
              case .development: return "https://engage-stage.warp.ly"
              case .production: return "https://engage.warp.ly"
              }
          }
      }
  }


Step 6: Core SDK Implementation (consolidating all layers)

  private init() {
      self.state = SDKState.shared
      self.network = NetworkService()
      self.storage = UserDefaultsStore()
      self.eventDispatcher = EventDispatcher()
  }

  // MARK: - Configuration
  public func configure(webId: String, merchantId: String, environment: Configuration.Environment = .production)

  // MARK: - Events & Analytics
  public func logEvent(_ event: Event)
  public func logTrackersEvent(_ eventType: String, _ eventName: String)
  public func subscribe<T: Event>(_ eventType: T.Type, handler: @escaping (T) -> Void)

  // MARK: - Push Notifications
  public func handleNotification(_ payload: [String: Any])

```swift
protocol Event {
  var name: String { get }
}


final class EventDispatcher {
      private var subscribers: [String: [(Any) -> Void]] = [:]

  func dispatch<T: Event>(_ event: T)
  func subscribe<T: Event>(_ eventType: T.Type, handler: @escaping (T) -> Void)
