## Main release

January 14, 2026

iOS App SDK: 9.4.0.165

## New in this Version

- The App SDK includes non-blocking APIs to support [modern threading](/dpoa/docs/s3suite94-using-the-app-sdk#error-handling). These improve your application's responsiveness and enable a smoother experience for your end users.
- TheTutorial app fetches the required version of the configuration information when [scanning the configuration QR code](/dpoa/docs/s3suite94-configuring-tutorial-web-app#configuring-ios-or-android-tutorial-app).
- The WebAuthn [conditional UI](/dpoa/docs/s3suite94-implementing-authentication-in-your-app#webauthn-credential-selection-ui) works with Quick Authentication.
- The logs generated by Nok Nok's [App IQ](/dpoa/docs/s3suite94-using-the-app-sdk#app-iq) error reporting service contain the username field in the data record.
- The App SDK can [silently register a new passkey](/dpoa/docs/s3suite94-implementing-authentication-in-your-app#automatically-create-a-passkey). Just check a box in the Server FIDO policy to allow end users to sign in and create a passkey in one step.
- A new biometric UAF [authenticator](/dpoa/docs/s3suite94-using-the-app-sdk#supported-authenticators) supports silent registration.
- The sign-up flow supports the [account creation](/dpoa/docs/s3suite94-implementing-authentication-in-your-app#creating-an-account-and-a-passkey) API in iOS 26.
- The App SDK is updated to support Public Key Credential Hints set by a [FIDO policy on the Server](/dpoa/docs/s3suite94-configure-fido2-authenticators#specify-desired-fido2-attributes). These settings control the presentation of the user interface for specific authenticators (security key, passkey on this device, and passkey on a different device), enabling more granular UI selection than was possible with Authenticator Attachment.
- The App SDK automatically [deletes deregistered credentials](/dpoa/docs/s3suite94-implementing-authentication-in-your-app#webauthn-credential-selection-ui). The opportunistic deletion of all WebAuthn credentials is implemented in the current release. When a FIDO2 platform authenticator is deregistered, the App SDK tries to delete the corresponding credential from the end user's device.
- The App SDK supports Liquid Glass UI.
- The App SDK is compatible with Swift 6.

## Issue Fixed in this Version

- Authentication on Tutorial watch app times out when using Quick Authentication.

Previous Behavior: Authentication on Tutorial watch app times out when using Quick Authentication. New Behavior: Authentication completes on Tutorial watch app when using Quick Authentication.

## Known Issue

Passkey registration is not working if your server uses an IPv6-only configuration. Apple drops your request if the domain record resolves to an IPv6 address only. There is a workaround that works only for enterprise users. If you receive the error below when attempting to register a passkey, consider the suggested resolution.

Error:

```plaintext

Application with identifier SG9R4B6BLT.com.noknok.ios.tutorialappplus is not associated with domain example.com
```

Resolution: Open your project with Xcode and navigate to the entitlements screen. Open Entitlements File > Associated Domains and add the following String Items:
