-ac and -ar parameters will become required in version 21.0.0

[Kyle Reis (Kyle-Reis)]

Since the 17.6.0 release of the Intune app wrapping tool for iOS in 2023, the tool has generated a warning when either the "-ac" or "-ar" options are not specified. These parameters will become required in the 21.0.0 release of the wrapping tool. The "-ac" and "-ar" parameters are used to specify the Entra client ID and redirect URI for the application, respectively. If your application has not yet been registered in Entra, please follow these instructions to create a registration and ensure the app can be successfully wrapped with version 21.0.0+ of the Intune app wrapping tool. Make sure to also grant your application access to the Intune MAM service within any tenants where it is used. If your application is registered as a single-tenant app and will only be used within a single tenant, then you should also specify the "-aa" option when wrapping to provide the authority URI for the tenant. The 21.0.0 release of the Intune app wrapping tool for iOS will be available in September of 2025. If you have any questions or concerns, please file an issue or reply directly to this announcement.

Hi Kyle Reis (@Kyle-Reis)

Can you please let us know if an application does not require a sign-in to a corporate M365 account, how can we skip the requirement for MSAL authentication and still apply the Intune SDK (via wrapping or integrated into the app code)?

Some custom applications might be wrapped simply to provide the Intune SDK and allow it to share data with other Intune App Protected applications, however the app may not necessarily require the user to log into a M365 account.

Thanks,
Nick

Nick (@Lorhaft) - This is not supported. MSAL is a required dependency of the Intune SDK. MAM policies are targeted to Entra accounts + client applications. In order for the Intune service to identify the correct policies to deliver to the application, the user must authenticate and enroll into MAM with a valid Entra account.

Hello Kyle Reis (@Kyle-Reis)

I’m currently using this tool.
With the latest update, the “-ac” and “-ar” parameters have become mandatory, but since we are not yet ready with Entra, we are still using the older version of the tool.
We plan to switch to the latest version as soon as the necessary settings are prepared, but we’d like to know: how long will we be able to continue using the older version?

Also, regarding the apps we have created so far using the old version of the tool — will we be able to continue using them without updating?

Hi UK-JP. In general, it is recommended that you keep your applications up-to-date with the latest available minor/patch update for an in-support major version of the app wrapping tool. Currently, versions 20.x and 21.x are supported. You can continue to use version 20.x as long as your apps are compiled with Xcode 16. However, using version 20.x of the wrapping tool on apps compiled with Xcode 26 is not supported. Such apps should be wrapped with version 21.x of the tool.

Version 20.x of the tool will continue to be supported until September 2026, when we release support for the next major Xcode version (presumably Xcode 27). However, support will be limited to high priority/security updates only.

For now, apps wrapped with 20.x will continue to work, provided you've updated them to at least version 20.8.1, per #143. At a later date, we will provide additional communications on the timeline for when such apps will no longer be able to communicate with the MAM service (beyond September 2026).

Thank you very much for your reply, Kyle Reis (@Kyle-Reis)

I’ve reviewed everything you mentioned and fully understand the details.
I’m relieved to hear that I have some time to prepare things on the Entra side.
I will move forward with preparations so that we can support version 21 as soon as possible.
