preOpenCard not running on iPhoneX simulator

Trap inside the preopencard handler.  LC fails silently in built
applications, so if some code or routine that is either directly or
indirectly triggered by the preopencard handler fails, the handler will
just stop executing.
You might be able to find out what's going on with the mobile debugger, too.

Do do it with code, try
on preopencard
answer "poc"

answer "pre doSomething"
answer "dosomething achieved"

answer "preDoSomethingElse
answer "doSomethingElse achieved"

answer "end poc"
end preopencard
