        I am trying to launch an app, and open a specific document with it.

        For example, to launch Sublime Text, I can do it using the following call

        [[NSWorkspace sharedWorkspace] launchAppWithBundleIdentifier:@"com.sublimetext.3" options:(0) additionalEventParamDescriptor:nil



        How do I pass a url of a document to the app, to make Sublime Text open this document after launch? I believe this can be done using additionalEventParamDescriptor, but I can't find an example anywhere on how to build a correct NSAppleEventDescriptor for an "open document" event.

          I use the following:

              [[NSWorkspace sharedWorkspace]
                openFile: /path/to/document
                withApplication: /path/to/app];


          You can use "absolutePathForAppBundleWithIdentifier" to convert a bundle ID to an absolute path.


          Note that the above works even from the sandbox and even when your document path is not sandbox-friendly. Also, /path/to/app is not Catalina-friendly. If you are running on Catalina and trying to open a system app, you must provide the "/System" prefix.


          It looks like both of these methods are deprecated in 10.15. You should probably use "openURLs:withApplicationAtURL:configuration:completionHandler:" and "URLForApplicationWithBundleIdentifier:" for new apps that don't need compatibility with 10.14 or earlier.
