New Feature

  • Native Xcode SDK applicable to Flutter, Cordova, and Ionic platform
    • The guide document of the Native Xcode SDK has been updated for the cross-platform. Although it does not encrypt the Javascript code used on the cross-platform, it can provide the same level of security features as our native SDK supports, such as jailbreak detection and integrity verification.

Bug Fixes

  • Fixed an error app closed due to false-positive during IPA integrity verification
    • The issue of terminating the app due to integrity verification failures such as “APP_INTEGRITY_CURRUPTED” has been fixed.
    • This issue was reported from the customers using Apple Push Notification Service plugin.
  • Updated how to use hash generating scripts.
    • The “generate_genesis” file has been added to fix the integrity verification issue. Before executing the “generate_hash” script, it is necessary to proceed with security settings. Please check the updated guide document in the new SDK for detailed instructions on how to use it.
  • Updated Security risk blocking GUI code
    • Modified the GUI sample codes in guide document so that the GUI window does not exit the app in debug mode.
