# "Framework"
This is a very simple pseudo-"integration test" project that links against
AsyncDisplayKit as a dynamic framework, for Swift/Carthage users.
If it fails to compile, Travis CI builds will fail. To escape from such dire straits:
* If you've added a new class intended for public use, make sure you added its
header to the "Public" group of the "Headers" build phase in the
AsyncDisplayKit-iOS framework target. Note that this smoke test will only fail
if you remembered to add your new file to the umbrella helper.
