This document serves as a guide for the 3DS SDK integrator of the Netcetera iOS 3DS SDK, providing details how should the SDK be configured and integrated into an iOS application or library.

Please check the release notes pages for detailed release notes about the current and previous versions of the Netcetera iOS 3DS SDK.

Versioning and Update Policy

The Netcetera iOS 3DS SDK follows the software versioning convention. The releases have semantic versioning scheme, meaning the version name will be composed of PROTOCOL.MAJOR.MINOR.PATCH.

  • PROTOCOL - major protocol version, i.e. 2
  • MAJOR - new features
  • MINOR - improvements
  • PATCH - bug or security fix

Because of limitations imposed by Apple, the minor and patch numbers are concatenated together. When ThreeDS2ServiceSDK.getSDKVersion() is called, the concatenated version will be returned, i.e. for version, the returned string would be 2.2.10.

It is recommended that the 3DS Requestor App always uses the latest available version of the SDK.
