🔧 Detailed Changes by Category


1. Critical Compilation Fixes


1.1 WarplySDK.swift - MODIFIED ⚠️ CRITICAL


File: SwiftWarplyFramework/SwiftWarplyFramework/Core/WarplySDK.swift

Problem: 4 compilation errors in constructCampaignParams(campaign:isMap:) method (lines 2669-2670)

Root Cause: Async/await mismatch - synchronous method calling async NetworkService methods

Changes Made:

// BEFORE (Causing compilation errors):
"access_token": networkService.getAccessToken() ?? "",      // ❌ ASYNC CALL
"refresh_token": networkService.getRefreshToken() ?? "",    // ❌ ASYNC CALL

// AFTER (Fixed):
// Get tokens synchronously from DatabaseManager
var accessToken = ""
var refreshToken = ""

do {
    if let tokenModel = try DatabaseManager.shared.getTokenModelSync() {
        accessToken = tokenModel.accessToken
        refreshToken = tokenModel.refreshToken
    }
} catch {
    print("⚠️ [WarplySDK] Failed to get tokens synchronously: \(error)")
}

let jsonObject: [String: String] = [
    // ... other parameters
    "access_token": accessToken,      // ✅ SYNC
    "refresh_token": refreshToken,    // ✅ SYNC

🔧 Legacy Credential Removal Session - June 27, 2025


Session Overview


Date: June 27, 2025

Session Type: Legacy Authentication System Removal

Primary Goal: Remove dependency on deprecated API credentials (api_key, web_id, client_id, client_secret)

Issues Resolved: 3 critical blocking issues

Files Modified: 4 files

Approach: Minimal changes to maintain stability  


🚨 Critical Issues Identified and Resolved


Issue #1: TokenRefreshManager Blocking Guard Statement


File: SwiftWarplyFramework/SwiftWarplyFramework/Network/TokenRefreshManager.swift

Problem: Guard statement required client_id and client_secret, causing token refresh to fail completely

Impact: ❌ CRITICAL - Token refresh completely blocked  

Before (Blocking):

guard let clientId = refreshParams["client_id"],
      let clientSecret = refreshParams["client_secret"],
      let refreshToken = refreshParams["refresh_token"] else {
    throw NetworkError.authenticationRequired
}


After (Non-blocking):

// Only refresh_token is required - client_id/client_secret are legacy credentials (deprecated)
guard let refreshToken = refreshParams["refresh_token"] else {
    throw NetworkError.authenticationRequired
}

// Use empty strings for legacy credentials (they're not needed anymore)
let clientId = refreshParams["client_id"] ?? ""
let clientSecret = refreshParams["client_secret"] ?? ""


Result: ✅ Token refresh now works without legacy credentials


Issue #2: WarplySDK Registration Validation


File: SwiftWarplyFramework/SwiftWarplyFramework/Core/WarplySDK.swift

Problem: Registration validation expected actual API key and Web ID values, throwing WarplyError code 5 when they were "deprecated"

Impact: ❌ CRITICAL - Device registration failed with WarplyError code 5  

Before (Blocking):

// Verify that API key and web ID were stored
let newApiKey = UserDefaults.standard.string(forKey: "NBAPIKeyUD")
let newWebId = UserDefaults.standard.string(forKey: "NBWebIDUD")

guard let apiKey = newApiKey, !apiKey.isEmpty else {
    throw WarplyError.dataParsingError
}

guard let webId = newWebId, !webId.isEmpty else {
    throw WarplyError.dataParsingError
}

print("✅ [WarplySDK] Device registration successful - API Key: \(apiKey.prefix(8))..., Web ID: \(webId)")


After (Non-blocking):

// Legacy credentials are deprecated - registration is successful regardless
print("✅ [WarplySDK] Device registration successful (legacy credentials deprecated)")


Result: ✅ Registration succeeds without WarplyError code 5


Issue #3: NetworkService Credential Warnings


File: SwiftWarplyFramework/SwiftWarplyFramework/Network/NetworkService.swift

Problem: Excessive warning logs and fallback logic for missing credentials

Impact: ⚠️ HIGH - Log spam and unnecessary processing  

Before (Warning-heavy):

private func getApiKey() -> String {
    let apiKey = UserDefaults.standard.string(forKey: "NBAPIKeyUD") ?? ""
    if apiKey.isEmpty {
        print("⚠️ [NetworkService] API Key not found in UserDefaults (key: NBAPIKeyUD)")
    }
    return apiKey
}

private func getWebId() -> String {
    let webId = UserDefaults.standard.string(forKey: "NBWebIDUD") ?? ""
    if webId.isEmpty {
        print("⚠️ [NetworkService] Web ID not found in UserDefaults (key: NBWebIDUD)")
        // Fallback to Configuration.merchantId if available
        let fallbackWebId = Configuration.merchantId
        if !fallbackWebId.isEmpty {
            print("🔄 [NetworkService] Using Configuration.merchantId as fallback web ID")
            return fallbackWebId
        }
    }
    return webId
}


After (Clean):

private func getApiKey() -> String {
    // Legacy credentials no longer needed - always return empty string
    return ""
}

private func getWebId() -> String {
    // Use merchant ID directly (no more UserDefaults lookup needed)
    return Configuration.merchantId
}


Registration Storage Fix:

// Before (Stored deprecated values)
if let apiKey = response["api_key"] as? String {
    UserDefaults.standard.set(apiKey, forKey: "NBAPIKeyUD")
    print("✅ [NetworkService] API Key stored: \(apiKey.prefix(8))...")
}

// After (Doesn't store deprecated values)
if let apiKey = response["api_key"] as? String {
    if apiKey != "deprecated" {
        print("ℹ️ [NetworkService] API Key received but not stored (legacy credential)")
    } else {
        print("ℹ️ [NetworkService] API Key is deprecated (expected)")
    }
}


Result: ✅ No more credential warnings, clean logs


Issue #4: TokenModel Legacy Credential Defaults


File: SwiftWarplyFramework/SwiftWarplyFramework/models/TokenModel.swift

Problem: TokenModel could store nil values for client credentials

Impact: 🟡 MEDIUM - Potential issues with token refresh parameters  

Before:

init(accessToken: String, refreshToken: String, clientId: String? = nil, clientSecret: String? = nil) {
    self.accessToken = accessToken
    self.refreshToken = refreshToken
    self.clientId = clientId
    self.clientSecret = clientSecret
    // ...
}


After:

init(accessToken: String, refreshToken: String, clientId: String? = nil, clientSecret: String? = nil) {
    self.accessToken = accessToken
    self.refreshToken = refreshToken
    self.clientId = clientId ?? ""  // Legacy credential - always use empty string
    self.clientSecret = clientSecret ?? ""  // Legacy credential - always use empty string
    // ...
}


Result: ✅ Consistent empty string handling for legacy credentials

After the initial legacy credential removal, a comprehensive search revealed 2 additional problematic checks that could still cause issues:


Issue #7: getCampaigns Authentication Logic (FINAL FIX)


File: SwiftWarplyFramework/SwiftWarplyFramework/Core/WarplySDK.swift

Problem: getCampaigns method failed with ERROR: -1 when user not authenticated due to failed getCampaignsPersonalized and getAvailableCoupons calls

Impact: ❌ CRITICAL - Campaign loading completely failed for non-authenticated users  

Root Cause: The method tried to call authentication-required endpoints (getCampaignsPersonalized and getAvailableCoupons) even when user was not logged in, causing the entire flow to fail.

Solution: Authentication-First Approach

// Check if user is authenticated to determine campaign processing approach
if self.isUserAuthenticated() {
    // User is authenticated - get full experience with personalized campaigns and coupon filtering
    print("✅ [WarplySDK] User authenticated - loading personalized campaigns and coupon availability")

    self.getCampaignsPersonalized(language: language, filters: filters, completion: { personalizedCampaigns in
        // ... full authenticated flow with parseCampaigns filtering
    })
} else {
    // User not authenticated - return all basic campaigns without coupon filtering
    print("ℹ️ [WarplySDK] User not authenticated - returning all basic campaigns without coupon filtering")

    // Skip parseCampaigns entirely - return raw campaigns without filtering
    completion(campaignsArray)
}


Key Changes:


Added isUserAuthenticated() helper method - checks database for valid, non-expired tokens

Authentication-first logic - check auth status before making dependent calls

Graceful degradation - non-authenticated users get basic campaigns without filtering

Skip parseCampaigns - for non-authenticated users to avoid empty results due to missing coupon availability


Result: ✅ No more ERROR: -1 - campaigns load successfully for both authenticated and non-authenticated users

Issue #5: NetworkService Signature Generation (CRITICAL)


File: SwiftWarplyFramework/SwiftWarplyFramework/Network/NetworkService.swift

Problem: Conditional signature generation that skipped the loyalty-signature header when API key was empty

Impact: ❌ CRITICAL - Missing signature header could cause API authentication failures  

Before (Problematic):

// Generate loyalty signature (apiKey + timestamp SHA256)
let apiKey = getApiKey()
if !apiKey.isEmpty {
    let signatureString = "\(apiKey)\(timestamp)"
    let signature = signatureString.sha256()
    request.setValue(signature, forHTTPHeaderField: "loyalty-signature")
}


After (Safe):

// Generate loyalty signature (apiKey + timestamp SHA256)
// Always generate signature, even with empty API key (server expects this header)
let apiKey = getApiKey()
let signatureString = "\(apiKey)\(timestamp)"
let signature = signatureString.sha256()
request.setValue(signature, forHTTPHeaderField: "loyalty-signature")


Result: ✅ Signature header always sent, preventing authentication failures


Issue #6: WarplySDK Registration Check (CLEANUP)


File: SwiftWarplyFramework/SwiftWarplyFramework/Core/WarplySDK.swift

Problem: Dead code that checked for non-empty legacy credentials (would never execute)

Impact: 🟡 MEDIUM - Unnecessary code that could confuse developers  

Before (Dead Code):

// Check if we already have API key and web ID
let existingApiKey = UserDefaults.standard.string(forKey: "NBAPIKeyUD")
let existingWebId = UserDefaults.standard.string(forKey: "NBWebIDUD")

if let apiKey = existingApiKey, !apiKey.isEmpty,
   let webId = existingWebId, !webId.isEmpty {
    print("✅ [WarplySDK] Device already registered - API Key: \(apiKey.prefix(8))..., Web ID: \(webId)")
    return
}


After (Clean):

// Legacy credentials are deprecated - always proceed with registration if needed
// (The server will handle duplicate registrations gracefully)


Result: ✅ Cleaner code, no more dead conditional logic
