1-1: Fix CI: update tests to match renamed APIs and changed signaturesTests in SpendConscienceTests fail (exit 65) because the codebase API/identifiers changed — update tests or provide stable test helpers.
- SpendConscienceTests/SpendConscienceTests.swift — PlaidService expectations call/inspect members that no longer exist or are private: lastError → currentError, accessToken/itemId are private, and the request‑creation helpers used in tests (createSandboxPublicTokenRequest, createTokenExchangeRequest, createAccountsRequest, createTransactionsRequest, formatDateForPlaid, setLoading/setError/clearError) are missing/renamed. Update tests to exercise the public API (isInitialized/isConnected/isLoading/currentError, async createSandboxPublicToken(), or add test-only accessors).
- PlaidConfiguration tests — test instantiates PlaidConfiguration and treats properties as instance/String values. PlaidConfiguration is static-based and uses an enum for environment; change tests to use PlaidConfiguration.clientId / PlaidConfiguration.secret / PlaidConfiguration.environment (compare to .sandbox) and PlaidConfiguration.validateCredentials().
- Plaid model tests — property names/types changed: PlaidTransaction uses id (not transactionId) and date is a Date; PlaidAccount uses balance (not balances). Adjust decoding tests to assert on actual model fields and types.
- TransactionStore tests — TransactionStore requires init(modelContext: ModelContext). Create an in‑memory ModelContainer/ModelContext for tests and call TransactionStore(modelContext:).
- Search/update other tests for renamed identifiers before re-running CI.

SpendConscience/PlaidConfiguration.swift (3)
149-150: Remove redundant string enum valuesThe SwiftLint warning is correct - when enum raw values match the case names, they can be omitted for cleaner code.
Apply this diff to remove redundant raw values:
enum PlaidEnvironment: String, CaseIterable { - case sandbox = "sandbox" - case production = "production" + case sandbox + case production
119-132: Deprecated property used in validation methodThe
validateCredentials()method uses the deprecatedapiKeyproperty instead of the newsecretproperty. This should be updated for consistency.Apply this diff to use the correct property:
static func validateCredentials() -> Bool { - guard let apiKey = apiKey, !apiKey.isEmpty else { + guard let secret = secret, !secret.isEmpty else { print("❌ PlaidConfiguration: Invalid or missing API key") return false }
135-142: Inconsistent property usage in logging methodSimilar to the validation method,
logConfiguration()uses the deprecatedapiKeyproperty.Apply this diff to use the correct property:
static func logConfiguration() { print("🔧 PlaidConfiguration Status:") print(" Environment: \(environment.rawValue)") print(" Base URL: \(baseURL)") - print(" API Key: \(apiKey != nil ? "✅ Present" : "❌ Missing")") + print(" API Key: \(secret != nil ? "✅ Present" : "❌ Missing")") print(" Client ID: \(clientId != nil ? "✅ Present" : "❌ Missing")") print(" Valid: \(validateCredentials() ? "✅" : "❌")") }SpendConscience/TransactionStore.swift (3)
93-94: Consider making pending transaction handling configurableCurrently, all pending transactions are silently skipped. Consider adding a property to optionally include pending transactions or at least log when they're skipped for better visibility.
Consider this enhancement:
+ /// Whether to include pending transactions in sync + var includePendingTransactions: Bool = false + for plaidTx in plaidTransactionData { // Skip pending transactions - if plaidTx.pending { continue } + if plaidTx.pending && !includePendingTransactions { + print("⏭️ TransactionStore: Skipping pending transaction: \(plaidTx.name)") + continue + }
155-156: Unreachable case in category mappingThe case on line 155 checking for "food and drink" with groceries will never be reached because "food and drink" is already handled on line 145.
Apply this diff to fix the category mapping logic:
switch primaryCategory { - case "food and drink", "restaurants": - return .dining + case "restaurants": + return .dining + case "food and drink": + // Check if it's groceries + if plaidCategories.contains(where: { $0.lowercased().contains("groceries") }) { + return .groceries + } + return .dining case "shops", "general merchandise": return .shopping case "gas stations", "transportation": return .transportation case "utilities", "telecommunication services": return .utilities case "recreation", "entertainment": return .entertainment - case "food and drink" where plaidCategories.contains("groceries"): - return .groceries
116-122: Consider adding transaction metadataThe Transaction initialization could benefit from preserving more metadata from Plaid, such as the merchant name (if different from transaction name) or the original Plaid transaction ID for reference.
Consider storing additional metadata:
let transaction = try Transaction( amount: amount, description: plaidTx.name, category: category, date: plaidTx.date, - accountId: plaidTx.accountId + accountId: plaidTx.accountId, + merchantName: plaidTx.merchantName, + externalId: plaidTx.id // Store Plaid transaction ID for reference )Note: This assumes the Transaction model supports these additional fields.

199-229: Fix MainActor isolation and property name (currentErrornotlastError).Access MainActor-isolated properties on the main actor and use the correct error property.

240-265: convertPlaidTransaction test helper diverges from production types.PlaidTransaction.date is Date (not String), and Transaction’s initializer doesn’t take merchantName/notes here. Either remove this helper or align to actual model APIs.
Minimal test rewrite (no helper):
- let plaidTransaction = PlaidTransaction( - transactionId: "test_id", - accountId: "test_account", - amount: 25.50, - date: "2024-01-15", - name: "Test Transaction", - merchantName: "Test Merchant", - category: ["Food and Drink", "Restaurants"] - ) - - let swiftDataTransaction = transactionStore.convertPlaidTransaction(plaidTransaction) - - #expect(swiftDataTransaction.amount == 25.50) - #expect(swiftDataTransaction.merchantName == "Test Merchant") - #expect(swiftDataTransaction.category.rawValue == "Food and Drink") - - // Test date conversion - let formatter = DateFormatter() - formatter.dateFormat = "yyyy-MM-dd" - let expectedDate = formatter.date(from: "2024-01-15") - #expect(swiftDataTransaction.date.timeIntervalSince1970 == expectedDate?.timeIntervalSince1970) + let json = #"{"transaction_id":"test_id","account_id":"test_account","amount":25.5,"date":"2024-01-15","name":"Test Transaction","merchant_name":"Test Merchant","category":["Food and Drink","Restaurants"]}"# + let plaidTx = try JSONDecoder().decode(PlaidTransaction.self, from: Data(json.utf8)) + let category = await transactionStore.mapPlaidCategoryToTransactionCategory(plaidTx.category ?? []) + let tx = try Transaction(amount: Decimal(abs(plaidTx.amount)), description: plaidTx.name, category: category, date: plaidTx.date, accountId: plaidTx.accountId) + #expect(tx.amount == 25.5) + #expect(tx.category == .dining)

108-115: Don’t fetch all transactions per item; use a predicate.Current code loads the entire table for each Plaid tx (N×full-table scans). Use a targeted FetchDescriptor with a predicate on accountId, amount, and date range.
- // Use a targeted fetch to find potential duplicates - let descriptor = FetchDescriptor<Transaction>() - let potentialDuplicates = try modelContext.fetch(descriptor).filter { existing in - existing.accountId == plaidTx.accountId && - existing.amount == amount && - existing.date >= startOfDay && - existing.date < endOfDay - } + let descriptor = FetchDescriptor<Transaction>( + predicate: #Predicate { t in + t.accountId == plaidTx.accountId && + t.amount == amount && + t.date >= startOfDay && t.date < endOfDay + } + ) + let potentialDuplicates = try modelContext.fetch(descriptor)Optional: batch by unique (accountId, amount, day) to reduce descriptor creation.

25-27: Nice hardening; add umask for defense-in-depth.Flags, mkdir -p, and chmod 600 are solid. Add a restrictive umask early to protect temp files on some shells.

25-28: Duplicate bundle lookup; remove the redundant alt path.Both lookups are identical; this just duplicates work and log noise.
- // Alternative bundle resource names - if let altBundlePlistPath = Bundle.main.path(forResource: "Config.Development", ofType: "plist") { - possiblePaths.append(altBundlePlistPath) - }
43-57: Fix mojibake in debug prints.The “�” characters suggest a bad paste; clean them up for readable logs.
- print(" � Bundle resources path: \(Bundle.main.resourcePath ?? "nil")") + print(" 📍 Bundle resources path: \(Bundle.main.resourcePath ?? "nil")") ... - print(" �💡 Run ./setup-development.sh to create the configuration file") + print(" 💡 Run ./setup-development.sh to create the configuration file")
62-72: Cache the loaded config to avoid repeated I/O on every get.Repeated bundle/disk reads on each call are unnecessary. Cache the first successful load.
struct ConfigurationLoader { - /// Loads configuration from plist file + private static var cached: [String: Any]? + /// Loads configuration from plist file static func load() -> [String: Any] { - var configuration: [String: Any] = [:] + if let cached { return cached } + var configuration: [String: Any] = [:] ... - configuration = plistData + configuration = plistData + cached = plistData print("📄 ConfigurationLoader: Loaded configuration from \(path)") breakSpendConscience/TransactionStore.swift (2)
152-164: Unreachable groceries branch.The “food and drink where contains groceries” case never hits because the prior case already matches “food and drink”.
- case "food and drink", "restaurants": - return .dining + case "food and drink" where plaidCategories.contains(where: { $0.lowercased().contains("grocer") }): + return .groceries + case "food and drink", "restaurants": + return .dining
76-78: Log inserted count, not input count.Count filtered duplicates/pending to reflect actual inserts.
- print("✅ TransactionStore: Synced \(plaidTransactions.count) Plaid transactions to SwiftData") + print("✅ TransactionStore: Sync complete (input: \(plaidTransactions.count), inserted: \(modelContext.registeredObjects.count))")Or maintain a local inserted counter in convertAndSaveTransactions and print that.

110-128: Consider decoupling tests from PlaidService internals.These helpers expose internal state; a protocol + test double would be cleaner and future‑proof.
I can sketch a PlaidServiceTestable protocol and a lightweight TestPlaidService for request construction if helpful.
SpendConscience/PlaidModels.swift (2)
488-513: Model/type naming consistency with tests.Tests reference PlaidAccountsResponse; the type here is AccountsResponse. Prefer consistent “Plaid*Response” or update tests (recommended).
351-439: PlaidError.networkError carries String; align all call sites.Some tests/extensions pass Error instead of String. Keep call sites passing error.localizedDescription (or consider changing the enum to carry Error).

12-21: POSIX DateFormatter and centralized encoding/decoding look great.Stable yyyy-MM-dd handling via en_US_POSIX + GMT avoids locale/timezone bugs. Encoding mirrors decoding. Nice.
