No file access permission for Cocoa app but works with command line app

Question

If I create a command line tool project and run something like:

NSError *error = nil;
NSFileManager *fileManager = [NSFileManager defaultManager];
if(![fileManager createDirectoryAtPath:@"/vault/ahh/eee" withIntermediateDirectories:YES attributes:nil error:&error])
{
    NSLog(@"couldn't make dir: %@", error);
}

I am actually able to make the 'eee' directory. But if I do the same thing with an app (Cocoa):

couldn't make dir: Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “eee” in the folder “ahh”." UserInfo={NSFilePath=/vault/ahh/eee, NSUnderlyingError=0x600000a5d800 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}

Why is this and what should I do for the app so that it can handle file accesses?

Found the answer. you can turn off sandbox by going to signing and capabilities tab and just remove the sandbox settings on the right.
