Visualize command gives error: use of undeclared identifier 'CFTypeRef'

When I run vi label were label is some UILabel, I’m getting this:

(lldb) vi label
error: error: use of undeclared identifier 'CFTypeRef'
error: use of undeclared identifier 'label'

Here’s a screenshot. As you can see, label is a UILabel that is currently in scope.

I tried with both the latest release from Homebrew and master. I’m using Xcode 8.0 and Swift 3.

Here’s a trivial sample project which you can use to reproduce this bug: https://cl.ly/hbOV

Any chance it’s something like having to call expr import CoreGraphics?

Thanks, it is possible that Chisel needs to do that. It will probably have to be expr @import CoreGraphics since Chisel commands generate objc. If this does work, I guess we’ll need some central location to manage and execute the imports, on behalf of commands.
