Xcode/iOS: How to enable App Groups without Developer Account?

Question

I want to create an iOS extension that requires the App Groups capability. According to the list of Supported Capablilities App Groups can be used without Developer Account. According to that document it should be possible with an Apple ID account.

When I try to enable App Groups for my application it fails to:

Add the "App Groups containers" entitlements to your App ID

Communication with Apple failed

There is an answer to question Xcode: Enable App Groups without developer account? which states that a Developer Account is required, which contradicts the official documentation.

Question XCode shows warning after adding App Groups (Add the “App Groups” entitlement to your App ID) does not contain helpful answers, as they also refer to an existing Developer Account. They point out that the error message provided by Xcode is not helpful.

So my question is, how to actually use App Groups without a Developer Account or is the official documentation erroneous?

Answer 1

As far as I am aware you must setup an App ID in the developer portal to do this (or let Xcode do the equivalent work for you). So, you will in fact need a developer account. Having said that, you should be able to do it with a free developer account.
