stripe/stripe-ios — reverse-engineered prompt

Build me an iOS payments SDK like Stripe’s that app developers can drop into their apps to accept payments quickly and safely.

I want it to include a simple prebuilt checkout sheet that collects payment details, billing details, and confirms the payment, plus lower level tools for developers who want to build their own payment screens. It should support credit cards, Apple Pay, 3D Secure authentication when needed, card validation, and card scanning on newer iPhones.

Please also include separate pieces for things like Apple Pay, identity verification, financial account connections, connected account dashboards, and payment UI so apps can choose only what they need. Make it feel native on iOS, localizable, privacy conscious, and safe for handling sensitive card data by sending it directly to the payment provider instead of through the app’s server.

Use Swift and make it easy to integrate through common iOS dependency managers. Look up current Apple and payment SDK docs online if you need to.
