Thanks a lot to everybody for helping!
I have tried a number of approaches.
For the moment , I have settled for an app group container.
Both apps are members of the same app group container.
In that, app A creates a file with the flags, then launches app B, and B reads
the flags file (if present
Thanks a lot.
I tried this in my app A , but I keep getting the error message
launch path not accessible
together with a stack trace.
I am getting the url to my app B like this:
url_ = NSWorkspace.shared.urlForApplication( withBundleIdentifier:
"de.zach.AppB" )
which points to /priva

Interesting. Will that work with all the sandboxing?
Can A create a file /tmp/info-for-B without any user intervention?
Can B read it *and* delete it?

Sounds good. How can A launch B as its sub-process? (and pass command line
arguments?)

If app B can be treated as a sub-process of app A you can use P
Write stuff to location in file the other app knows about, then read it.

Thanks a lot for your reponse.
Yes , it is sandboxed.
... Argh, the *last* line of the docs of configuration.arguments tell that
those are ignored! :-(
So, the new question is: is there any easy way how my app A can launch my app B
and pass a simple piece of info from A to B, such as a boolean

Is your app sandboxed? Arguments are ignored in sandboxed applications.
