stringByAppendingFormat: returns the new string, it does not modify the receiver string. That's why you are getting no change. Try this:

NSMutableString  *selectDay=@"Wed 14 May";
NSString *newString = [selectDay stringByAppendingFormat:@"%i", yearNumber];
NSLog(@"%@", newString);

Or this:

NSMutableString  *selectDay=@"Wed 14 May";
NSString *newString = [NSString stringWithFormat:@"%@%i", selectDay, yearNumber];
NSLog(@"%@", newString);

EDIT: Actually you don't need mutable string for this. selectDay should be a normal NSString.

NSString  *selectDay=@"Wed 14 May";
