Issue/Introduction

This KB article addresses common questions raised regarding iOS platform support and SDK versioning information observed during DDNA iOS SDK integration and testing.

Specifically, it clarifies:

  • The minimum supported iOS version requirement: MinimumOSVersion: 15.5. Is iOS 15.5 truly a requirement for the SDK, or can it run on iOS 14?

  • A version mismatch observed in the Info.plist file: CFBundleShortVersionString Mismatch (8.3.6 vs 8.4.1). However, version 8.4.1 was referenced in prior discussions. Is this a mistake or an oversight in the Info.plist file?

Environment

Advanced Authentication 9.1.5 DDNA iOS SDK

Resolution

Minimum iOS Version Requirement (MinimumOSVersion = 15.5)

Apple now considers iOS 14 obsolete. All devices capable of running iOS 14 are also eligible to upgrade to iOS 15 or later. In alignment with Apple’s platform lifecycle and support policy:

  • The AA / DDNA SDK officially supports iOS 15.5 and above

  • iOS 14 is no longer supported by the SDK

Supported iOS Versions

The following iOS versions are supported:

  • iOS 15.5

  • iOS 16

  • iOS 17

  • iOS 18

  • iOS 26 (GA, GA-4)

Resolution

This behavior is by design.

  • No fix is required on the DDNA SDK side

  • Customers should align their application’s minimum OS requirement with iOS 15.5 or later

Issue 2: CFBundleShortVersionString Mismatch (8.3.6 vs 8.4.1)

Yes, there is a version mismatch in the Info.plist file.

  • The version shown (8.3.6) does not reflect the intended release version (8.4.1)

  • This is a labeling issue only and does not affect any functional SDK behavior

Resolution

  • The mismatch will be corrected in an upcoming SDK release

  • Customers may continue using the current DDNA SDK for development and testing

  • No reconfiguration or workaround is required

Additional Information

The DDNA iOS SDK intentionally enforces a minimum iOS version of 15.5 to remain aligned with Apple’s supported platforms. Additionally, a cosmetic version mismatch in the Info.plist file has been identified and will be resolved in a future release, with no impact on functionality.
