While testing some of our pyobjc-based code on the current OS X 10.11 (El Capitan) beta, we encountered problems with the use of LaunchServices framework. For example, the following code that works on OS X 10.10 and earlier no longer works on OS X 10.11.
from LaunchServices import LSSharedFileListCreate
Basically, Apple has deprecated the SharedFileList API, and, in the process, appears to have separated the API from LaunchServices into its own framework (SharedFileList.framework). That's probably why the SharedFileList imports no longer work through pyobjc-framework-LaunchServices.
Note that any Objective-C code that uses the ShareFileList API and that previously linked against the CoreServices umbrella framework continues to work fine on OS X 10.11.
Will pyobjc continue to support the SharedFileList API?
