SelectDirectory() no longer works in Catalina

[trev]

Code: Pascal  [Select]

1. SelectDirectory('Select the GCB chipdata folder','',selectedDir);
2.  

and

Code: Pascal  [Select]

1.  selDir := TSelectDirectoryDialog.Create(nil);
2.  
3.       Try
4.            selDir.Title:='Select GCB data folder';
5.            if selDir.Execute then
6.                     selectedDir := selDir.FileName;
7.            finally
8.                     selDir.Free;
9.            end;
10.  

In Catalina Beta 5, SelectDirectory and (my second attempt) TSelectDirectoryDialog are both silently ignored. No problem for either under Mojave.

Checking the Catalina logs I find:

Is this related to the removal of the Carbon framework and:

Deprecations

macOS frameworks are now thinned for the x86-64 architecture. Apps that execute i386 code now fail with the EBADARCH error code. The remaining stub frameworks are nonfunctional and exist only for compatibility purposes. (51236070)

[Thaddy]

Seems a similar issue that arose with win-x86_64, where you could only write shell extensions in 64 bit code. Apart from changing to all 64 bit code, that Apple expects you to do, there's not much else we can do from the Lazarus side if that is the case.

[trev]

I am compiling all 64 bit code with the Cocoa widget set. If you look at the log snippet I posted, you will see calls to the Carbon framework (eg NSCarbonMenuImpl _carbonCommandProcessEvent:handlerCallRef)  which is indeed only 32 bit and either removed or non-functional in Catalina.
