# iOS integration

[View source](/point-of-sale/classic-library-deprecation/classic-library-integrations/ios-integration.md)

We are [discontinuing classic libraries](/point-of-sale/classic-library-deprecation). If you are currently using a classic library, you need to migrate to [Terminal API](/point-of-sale/design-your-integration/terminal-api).\
Do not build a new integration with a classic library.

Use the iOS app and libraries to integrate your iOS-based POS solution with the Adyen payments platform. This library enables communication between your POS solution, written in Objective-C or Swift, and the PED firmware.
