Access eligible financial data from Apple Wallet, including U.S. Apple Card, Apple Cash, Savings, and U.K. connected-account data. FinanceKit provides on-device access to accounts, balances, and transactions with user-controlled authorization. Targets Swift 6.3 / current Apple platforms; query APIs are available from iOS/iPadOS 17.4, TransactionPicker from iOS/iPadOS 18, and background delivery from iOS/iPadOS 26.
Keep FinanceKit guidance focused on financial-data access, Wallet order storage/querying, TransactionPicker, and background delivery. Route Apple Pay checkout to PassKit, widget UI/timeline work to WidgetKit, and Wallet order-tracking email or Apple Business Connect optimization outside this skill.
com.apple.developer.financekit from Apple via the FinanceKit entitlement request form. This is a managed capability; Apple reviews each application.NSFinancialDataUsageDescription to Info.plist -- this string is shown to the user during the authorization prompt.xml<key>NSFinancialDataUsageDescription</key> <string>This app uses your financial data to track spending and provide budgeting insights.</string>
U.S. FinanceKit financial data requires iOS/iPadOS 17.4+ and currently covers eligible Apple Card, Apple Cash, and Savings data; Apple Card Family participants and Apple Cash Family children are excluded. U.K. support requires iOS/iPadOS 18.4+ and uses open banking for supported institutions. Orders APIs are available separately from financial-data query APIs.
Check whether the device supports FinanceKit before making any API calls. This value is constant across launches and iOS versions.
swiftimport FinanceKit guard FinanceStore.isDataAvailable(.financialData) else { // FinanceKit not available -- do not call any other financial data APIs. // The framework terminates the app if called when unavailable. return }
For Wallet orders:
swiftguard FinanceStore.isDataAvailable(.orders) else { return }
Data availability returning true does not guarantee data exists on the device. Data access can also become temporarily restricted (e.g., Wallet unavailable, MDM restrictions). Restricted access throws FinanceError.dataRestricted rather than terminating.
Request authorization to access user-selected financial accounts. The system presents an account picker where the user chooses which accounts to share and the earliest transaction date to expose.
swiftlet store = FinanceStore.shared let status = try await store.requestAuthorization() switch status { case .authorized: break // Proceed with queries case .denied: break // User declined case .notDetermined: break // No meaningful choice made @unknown default: break }
Query current authorization without prompting:
swiftlet currentStatus = try await store.authorizationStatus()
Once the user grants or denies access, requestAuthorization() returns the cached decision without showing the prompt again. Users can change access in Settings > Privacy & Security > Financial Data.
Accounts are modeled as an enum with two cases: .asset (e.g., Apple Cash, Savings) and .liability (e.g., Apple Card credit). Both share common properties (id, displayName, institutionName, currencyCode) while liability accounts add credit-specific fields.
swiftfunc fetchAccounts() async throws -> [Account] { let query = AccountQuery( sortDescriptors: [SortDescriptor(\Account.displayName)], predicate: nil, limit: nil, offset: nil ) return try await store.accounts(query: query) }
swiftswitch account { case .asset(let asset): print("Asset account, currency: \(asset.currencyCode)") case .liability(let liability): if let limit = liability.creditInformation.creditLimit { print("Credit limit: \(limit.amount) \(limit.currencyCode)") } }
Balances represent the amount in an account at a point in time. A CurrentBalance is one of three cases: .available (includes pending), .booked (posted only), or .availableAndBooked.
swiftfunc fetchBalances(for accountID: UUID) async throws -> [AccountBalance] { let predicate = #Predicate<AccountBalance> { balance in balance.accountID == accountID } let query = AccountBalanceQuery( sortDescriptors: [SortDescriptor(\AccountBalance.id)], predicate: predicate, limit: nil, offset: nil ) return try await store.accountBalances(query: query) }
Amounts are always positive decimals. Use creditDebitIndicator to determine the sign:
swiftfunc formatBalance(_ balance: Balance) -> String { let sign = balance.creditDebitIndicator == .debit ? "-" : "" return "\(sign)\(balance.amount.amount) \(balance.amount.currencyCode)" } // Extract from CurrentBalance enum: switch balance.currentBalance { case .available(let bal): formatBalance(bal) case .booked(let bal): formatBalance(bal) case .availableAndBooked(let available, _): formatBalance(available) @unknown default: "Unknown" }
Use TransactionQuery with Swift predicates, sort descriptors, limit, and offset.
swiftlet predicate = #Predicate<Transaction> { $0.accountID == accountID } let query = TransactionQuery( sortDescriptors: [SortDescriptor(\Transaction.transactionDate, order: .reverse)], predicate: predicate, limit: 50, offset: nil ) let transactions = try await store.transactions(query: query)
swiftlet amount = transaction.transactionAmount let direction = transaction.creditDebitIndicator == .debit ? "spent" : "received" print("\(transaction.transactionDescription): \(direction) \(amount.amount) \(amount.currencyCode)") // merchantName, merchantCategoryCode, foreignCurrencyAmount are optional
FinanceKit provides factory methods for common filters:
swift// Filter by transaction status let bookedOnly = TransactionQuery.predicate(forStatuses: [.booked]) // Filter by transaction type let purchases = TransactionQuery.predicate(forTransactionTypes: [.pointOfSale, .directDebit]) // Filter by merchant category let groceries = TransactionQuery.predicate(forMerchantCategoryCodes: [ MerchantCategoryCode(rawValue: 5411) // Grocery stores ])
For a transaction field table and more query patterns, read references/financekit-patterns.md.
Use AsyncSequence-based history APIs for catch-up sync, live updates, or resumable sync. These return inserted, updated, and deleted item IDs plus a HistoryToken.
swiftfunc catchUpTransactions(for accountID: UUID) async throws { let history = store.transactionHistory( forAccountID: accountID, since: loadSavedToken(), isMonitoring: false // finish after saved-token catch-up ) for try await changes in history { removeLocalRecords(withIDs: changes.deleted) upsert(changes.inserted + changes.updated) saveToken(changes.newToken) } }
HistoryToken conforms to Codable. Persist it to resume queries without reprocessing data:
swiftfunc saveToken(_ token: FinanceStore.HistoryToken) { if let data = try? JSONEncoder().encode(token) { UserDefaults.standard.set(data, forKey: "financeHistoryToken") } } func loadSavedToken() -> FinanceStore.HistoryToken? { guard let data = UserDefaults.standard.data(forKey: "financeHistoryToken") else { return nil } return try? JSONDecoder().decode(FinanceStore.HistoryToken.self, from: data) }
If a saved token points to compacted history, the framework throws FinanceError.historyTokenInvalid. Discard the token, then immediately run a fresh catch-up query for the affected account or balance stream so local state and the replacement token are rebuilt. Use isMonitoring: true only for a separate live monitor.
swiftlet accountChanges = store.accountHistory(since: nil, isMonitoring: true) let balanceChanges = store.accountBalanceHistory(forAccountID: accountID, since: nil, isMonitoring: true)
Ongoing budgeting sync should cover the data model the user authorized: account objects for account additions/removals, account balances for trend and widget state, and transactions for spending detail. Use separate history tokens per stream or account so a compacted token only forces resync of the affected stream.
For apps that need selective, ephemeral access without full authorization, use TransactionPicker from FinanceKitUI. Access is not persisted -- transactions are passed directly for immediate use.
swiftimport FinanceKitUI struct ExpenseImportView: View { @State private var selectedTransactions: [Transaction] = [] var body: some View { if FinanceStore.isDataAvailable(.financialData) { TransactionPicker(selection: $selectedTransactions) { Label("Import Transactions", systemImage: "creditcard") } } } }
FinanceKit supports saving and querying Wallet orders (e.g., purchase receipts, shipping tracking).
swiftlet result = try await store.saveOrder(signedArchive: archiveData) switch result { case .added: break // Saved case .cancelled: break // User cancelled case .newerExisting: break // Newer version already in Wallet @unknown default: break }
swiftlet orderID = FullyQualifiedOrderIdentifier( orderTypeIdentifier: "com.merchant.order", orderIdentifier: "ORDER-123" ) let result = try await store.containsOrder(matching: orderID, updatedDate: lastKnownDate) // result: .exists, .newerExists, .olderExists, or .notFound
swiftimport FinanceKitUI AddOrderToWalletButton(signedArchive: orderData) { result in // result: .success(SaveOrderResult) or .failure(Error) }
iOS 26+ supports background delivery extensions that notify your app of financial data changes outside its lifecycle. User authorization made in the main app is inherited by the extension. Both targets need the FinanceKit entitlement; use App Groups to share data between the app, extension, and related widgets.
These registration methods are synchronous and nonthrowing; do not write try or await.
swiftstore.enableBackgroundDelivery( for: [.accounts, .accountBalances, .transactions], frequency: .daily )
Available frequencies: .hourly, .daily, .weekly. These are expected minimum intervals between extension launches when data changes; longer frequencies give the extension a larger processing window.
Disable selectively or entirely:
swiftstore.disableBackgroundDelivery(for: [.transactions]) store.disableAllBackgroundDelivery()
Create a background delivery extension target in Xcode (Background Delivery Extension template). Implement the two async entry points directly on the extension type and return from didReceiveData(for:) only after essential work is saved.
swiftimport FinanceKit @main struct MyFinanceExtension: BackgroundDeliveryExtension { func didReceiveData(for types: [FinanceStore.BackgroundDataType]) async { if types.contains(.transactions) { await processNewTransactions() } if types.contains(.accountBalances) { await updateBalanceCache() } if types.contains(.accounts) { await refreshAccountList() } } func willTerminate() async { await savePartialWork() } }
DON'T -- skip availability check:
swiftlet store = FinanceStore.shared let status = try await store.requestAuthorization() // Terminates if unavailable
DO -- guard availability first:
swiftguard FinanceStore.isDataAvailable(.financialData) else { showUnavailableMessage() return } let status = try await FinanceStore.shared.requestAuthorization()
DON'T -- treat amounts as signed values:
swiftlet spent = transaction.transactionAmount.amount // Always positive
DO -- apply the indicator:
swiftlet amount = transaction.transactionAmount.amount let signed = transaction.creditDebitIndicator == .debit ? -amount : amount
DON'T -- assume authorized access persists:
swiftlet transactions = try await store.transactions(query: query) // Fails if Wallet restricted
DO -- catch FinanceError:
swiftdo { let transactions = try await store.transactions(query: query) } catch let error as FinanceError { if case .dataRestricted = error { showDataRestrictedMessage() } }
Use the canonical transaction-history loop above and persist each newToken only after local deletes and upserts commit. Keep separate tokens per stream/account; on invalid-token errors, resync only the affected scope.
Both asset and liability accounts use .debit for outgoing money. But .credit means different things: on an asset account it means money received; on a liability account it means a payment or refund that increases available credit.
