To quickly try a snippet of code in objective-c using clang from the command line. 1. Create a "main.m" file (see example below) 2. Compile using "clang -o main main.m -lobjc -framework Foundation" 3. Run "./main"

main.m

#import <Foundation/Foundation.h>

int main(int argc, char *argv[])
{
    NSArray *array = @[ @"a", @"b", @"c" ];

    for (NSUInteger i = 0; i < array.count; i++)
    {
        NSLog(@"%@", array[i]);
    }
}
