Versioning and Change log

PCI-SSF assessment and certification

The Checkout iOS SDK has gone through a thorough assessment against the PCI-SSF standard and is now certified PCI-SSF compliant. This will help you reduce the scope of your own PCI assessments.

Minimum version requirements:

• The minimum iOS version supported by the SDK for the purpose of providing a PCI-SSF compliant solution is iOS 15
• Although the SDK supports iOS 12 to iOS 14 it is not PCI-SSF compliant for these versions. This is because Apple has stopped supporting/delivering security fixes for these versions

Version 3 functionality we have removed in version 4:

• Support for using UITextField. AccessCheckoutUITextField must be used instead. This component is dedicated to capturing and encapsulating your customer's card details to minimize your exposure to PCI Data
• Support for passing card details directly to create an instance of CardDetails
• Support for using merchantId() in AccessCheckoutClientBuilder to pass your Checkout ID. This is replaced by checkoutId()

Licensing

The Access Checkout iOS SDK license is now a proprietary license (previously open source). This is for the purpose of protecting you against a risk of breaking changes in case where the Worldpay APIs, consumed by the SDK, are to change in the future.

Support for enhanced card sessions

• The SDK now returns a card session URL in the form of https://access.worldpay.com/sessions/.... Previously, the card session URL looked like this: https://access.worldpay.com/verifiedTokens/sessions/...

The format of the new card session URL supports our new upcoming Payments API, whilst also remaining compatible with our Verified Tokens API.

Support for SAQ-A compliance

• We have added a new UI Component (AccessCheckoutUITextField) dedicated to capturing and encapsulating your customer's card details to minimize your exposure to PCI Data

At a high level, you now pass references of instances of this UI component to our SDK. The SDK ensures you don't have to manipulate card details directly. This allows your application to be assessed against the PCI SAQ-A standard.

Version 2 functionality that is deprecated in version 3:

• Support for using UITextField (planned removal in version 4)
• Support for directly passing card details to create an instance of CardDetails (planned removal in version 4)
• Support for using merchantId() in AccessCheckoutClientBuilder to pass your Checkout ID is deprecated and replaced by checkoutId() (planned removal of merchantId() in version 4)

Minimum version requirements

• The minimum version supported is iOS 12

Version 2 has a simplified integration and caters for CVC session creation for our Android and iOS SDK.

Swift Package Manager support is now available for our iOS SDK version 2.4.0 onwards.

PAN formatting allows you to format the card in your checkout form as the customer types.

The card brand configuration allows you to restrict the cards that you accept on your checkout form.

The new version of the iOS SDK is 2.1.0 to add support for UITextFields in the validation feature.

We have increased the lifespan of the CVC session from one minute to 15 minutes.
