Framework not found ARKit

When building for iOS using remote build, I can connect to the remote Mac and begin the build process, but it fails with the error “ld: framework not found ARKit”. I have checked that the Mac has the v9 Beta version of XCode installed, and I can build AR projects to a device from that computer through XCode. What am I missing here?

Relevant log text:

UATHelper: Packaging (iOS): UnrealBuildTool: clang: error: linker command failed with exit code 1 (use -v to see invocation)

As an update, I searched the System/Library/Frameworks and Library/Frameworks folders on my Mac remote client, but I’m not finding an ARKit framework file anywhere. However, I know that XCode can build an ARKit app from that machine. What am I missing?

Found the problem; I had an older version of XCode installed on the Mac as well as the new Beta, and it was looking to the wrong one as the default.
