Hi,
the package UI Builder (v. 0.11.2-preview) doesn’t compile with Unity 2020.2.0a15.
It seems like the class UnityEditor.StyleSheets.StyleSheetImporterImpl doesn’t exist anymore.
Compile error:
Library\PackageCache\com.unity.ui.builder@0.11.2-preview\Editor\Utilities\StyleSheetExtensions\StyleSheetUtilities.cs(13,25): error CS0246: The type or namespace name ‘StyleSheetImporterImpl’ could not be found (are you missing a using directive or an assembly reference?)
We’ll have a new release of the UI Builder package soon that will work with 2020.2.0a15 and newer. This versions will therefore no longer work with 2020.2.0a14 or older (which is why we didn’t release it earlier). For now, if you need to use the UI Builder, you’ll need to hold off updating to the latest Unity alpha.
Ok sure, we will hold off on updating it.
Will you maintain 2 versions, one 2020.2.0a15+ and one below, or you’ll just need to use the latest alpha to use the UI Toolkit editor from that release version onwards?
The next UI Builder version will require 2020.2.0a15 or newer builds of 2020.2. We will not maintain two versions as these are all alpha builds that come with no support. This is bound to happen as we stabilize APIs. If you need to go back to an earlier 2020.2 version, you can temporarily downgrade the UI Builder package. This should not break any assets.
That’s great news, thank you!
UI Builder 1.0.0-preview.1 is out now which supports 2020.2.0a15 and newer.
