Financekit

If you're building iOS apps that need to work with Apple Card, Apple Cash, or Savings data, this wraps the FinanceKit framework with clear guidance on the authorization flow, querying transactions and balances, and handling the managed entitlement process. It covers the practical details like checking data availability before making calls (the framework terminates your app otherwise), using Swift predicates for filtering transactions, and working with the enum-based account types. The background delivery and transaction picker sections are helpful for building finance apps that feel native to iOS. Note that you'll need an organization-level developer account and Apple's approval for the entitlement, so this isn't for quick prototypes.
