Re: NSScreen.screens under multiple displays

[Jeff Szuhay via Cocoa-dev]

You may have to go to the Quartz level to get the active display list with

CGError 
 
CGGetOnlineDisplayList( uint32_t  maxDisplays, 
CGDirectDisplayID 

 *onlineDisplays, 
uint32_t *displayCount);

see

I have been meaning to do this when I get around to updating my app but I have 
not not played with this yet.
Sample code? Sample code? Anyone?

Re: Thoughts on Objective-C++

[Jeff Szuhay via Cocoa-dev]

You made a business decision and now you must live with that decision.

Otherwise, this thread is really getting tiresome.

Re: Best Xcode machine mid-2019?

[Jeff Szuhay via Cocoa-dev]

Compilation is largely an i/o-bound problem. Unless the projects you work on 
are hideously
large and would benefit from parallel processing (splitting the i/o among 
several processors), 
your current machine is quite satisfactory. 

Try this: using your current system, create a 4GB disk partition in memory. 
Then make that
partition the “Derived Data” location. 

You can see how here:

If you notice an improvement in stability and decreased build time, great. If 
not, just keep
on building great apps.
