Hi all,
I'm working on application that access user system preferences and
files/directories stored on system disk and other storage attached to
the system. On macOS Catalina after running each build system is
asking to allow access to System Events and files in different
locations:

Quote“application” wants access to control “System Events“. Allowing
control will provide access to documents and data in “System Events“,
and to perform actions within that app.Quote“application” would like
to access files on a network volume.Quote“application” would like to
access files in your Desktop folder.Quote“application” would like to
access files in your Documents folder.Quote“application” would like to
access files in your Downloads folder.
Each new build is recognized by the system as different application,
so it again is asking for permissions. What is interested this hasn't
happen in macOS Mojave - it was enough to allow this once and each new
compilantion has run without security dialogs.

How to bypass this security control during development process in
macOS Catalina?

Best regards,
Inferno

From Eskimo (Apple Forum Dev):

QuoteIs your app code signed?  Most problems like this are caused by
the app not being code signed, so the system can’t be sure that the
new build of your app is the same code as the previous build that was
OK’d be the user.

That probably explains it. I noticed even Mojave is logging a check
for signing on every rebuilt application's launch but of course,
unlike Catalina, it's not enforcing access permission requests.

It cannot be bypassed, it's a feature

Apple last time makes tons of "improvements" especailly related to the
security. But they forget to check how it affect the users...

So if I sign the code and allow once for access to System Events and
files locations, system will not ask for permissions during all next
compilations?

Best regards,

The effect is fully intended for the "users" and only happens the
first time the application is run. It's a little different for the
developers

I can't guarantee it, but it would seem to be implied by Eskimo if you
incorporate code signing into your rebuilding workflow.

The alternative is to use Mojave for development which is what I do.
