# Upgrade to the latest version of Checkout Kit to avoid issues with iOS 26

Checkout Kit’s preloading feature is not compatible with the upcoming release of iOS 26. This incompatibility will prevent buyers from completing their checkout process within the app. If no action is taken, customers using devices with iOS 26 will encounter blank checkout pages and will be unable to finalize their purchases.

To prevent this issue, promptly update your apps to the latest versions of Checkout Kit. Use the following versions: [Swift 3.3.1](https://github.com/Shopify/checkout-sheet-kit-swift/releases/tag/3.3.1), [Kotlin 3.5.1](https://github.com/Shopify/checkout-sheet-kit-android/releases/tag/3.5.1), and [React Native 3.3.1](https://github.com/Shopify/checkout-sheet-kit-react-native/releases/tag/3.3.1).
