I know that Xcode still lets you write apps in Objective - C, but there is hardly any (new) documentation, and very few new apps are written in it. To add to the question - how viable would it be to learn and write a new app in Objective - C in 2021?

I tried to find the file inside the ios emulator. When I scan the directory all the time, it finds my Mac Book local directory. I don't know why the external folder is being read by the emulator. Turn it off or Is there any way to access the folder inside the emulator? The code proceeds from a test application written in Objective-C. Here's the code:    if ((dir = opendir("/Users/macAccount")) != nullptr) {     while ((diread = readdir(dir)) != nullptr) {       printf ("target : %s", diread->d_name);     }     closedir (dir);   } ==> result (This is the contents of my account on the macbook.)  .android| DataGripProjects| Public| .ssh| Movies| .vimrc| Applications| .gradle| .Trash| Mon.tar.gz| .npm| ...

I'm getting back to coding after a while and I don't see the option to create an ObjC project with Storyboards in Xcode 13. Please tell me how? Thanks Neerav

Is it possible that AppA and AppB which are from the same developer share some local resources on a given device.For instance:Can the data written by App A, be read by App B (through Shared Defaults or any other mechanism)?The following link is to a similar question raised on stackoverlfow. I wanted to be certain thus, raising this question on Apple Dev Forums.https://stackoverflow.com/questions/9079378/shared-resources-for-two-apps-from-the-same-developer

I really can't find the reason for the crash.

I have the following code:@implementation NSWindow (Coordination) - (NSPoint)convertPointFromScreen:(NSPoint)point { NSRect rect = NSMakeRect(point.x, point.y, 1, 1); return [self convertRectFromScreen:rect].origin; }I get a compiliation warning:Category is implementing a method which will also be implemented by its primary classI know Swift has builtin preprocessor directives to detect SDK version, but don't know how to do this in objc. Any suggestions?

Any update from Apple on CVE-2021-42574 fix ?
