Elements ships with pre-imported .fx files for all macOS, iOS, iPadOS, tvOS and watchOS SDKs that are available at the time the current weekly build is shipped.
Sometimes there will be overlap and a new version of Xcode, iOS or macOS is released and we are not ready to ship an updated version of Elements the same day or week. In that case, EBuild will automatically download the required .fx files for you, on first compile, but you can also manually download them below, or import news SDK yourself.
These SDK downloads for Elements v10 are available:
(they require a recent Elements build, currently 2315 or later)
