FinanceKit

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.

Setup and Entitlements

Requirements

Managed entitlement -- request com.apple.developer.financekit from Apple via the FinanceKit entitlement request form. This is a managed capability; Apple reviews each application.
Organization-level Apple Developer account (individual accounts are not eligible).
Account Holder role required to request the entitlement.
Eligible App Store app -- the app must be in the Finance category, distributed through the App Store for iPhone in the United States or United Kingdom, and provide financial-management tools such as net-worth, spending, or budgeting features.
Per-bundle-ID approval -- Apple assigns the entitlement to the approved bundle ID; do not assume it applies to sibling apps or extensions automatically.
If the app offers financial products directly or through a regulated institution, it must allow customers to connect those accounts to Apple Wallet and share the data with FinanceKit.

Project Configuration

Add the FinanceKit entitlement through Xcode managed capabilities after Apple approves the request.
Add NSFinancialDataUsageDescription to Info.plist -- this string is shown to the user during the authorization prompt.
For iOS 26 background delivery, add the FinanceKit entitlement to both the app and extension targets, then use App Groups for shared storage.
