Hello... I've recently started the Objective-C course. And I've gotten a few videos in... I am pretty fluent in Swift already, but I will likely not make my first App in Swift because its not a stable language yet, which is why I'm learning Objective-C (Just to be clear, I am fluent in Swift Syntax, I am not fluent in App making)

I had a few questions though...

To create a variable, instead of using "var" like in swift, you do "NSString *<stringname>;" (Without quotes) is it essentially just a var without the var prefix? It's just a direct way of saying we're making a variable of type String. Without the "var str: String"?

Also... in this case:

import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) { @autoreleasepool { // insert code here... NSLog(@"Hello, World!"); }

NSString *firstName;
firstName = @"Ryan";
NSLog(@"firstName: %@", firstName);



return 0;

}

NSString *str = @"Test";

It won't let me declare a string variable outside of the main function... is that normal? Does all code need to be inside of a main function or a function with argc and stuff declared??? I may sound very noobish but I really want to understand this so later I'm not totally lost.
