Totally new to iOS and am starting out with Objective-C. Been trying to figure out how to correctly output this NSLog string. I want the length of the "Hello, World!" to output. I believe the result should be "Here is the length of the string:12" right?

Can someone show me the code to fix this? Currently the result i'm getting is
"Here is the length of the string:0x1.fffe332cf2cp-1028"


// 3 ways of using @ and NSString. Each valid.
        NSString *myString = @"Hello, World!";
        int len = [myString length];
        
        len = [@"Hello, World!" length];
        
        myString = [[NSString alloc] initWithString:@"Hello, World!"];
        len = [myString length];
        
        NSLog(@"Here is the length of the string:%a",len);

NSLog is fine but it is a lot of work sometimes and your xcode output become filled with too much text.

Pause your code after mySting has been init with "Hello World" and then in xCode where all the output information is put this


po [myString length]
