The original request from asked for an Objective-C tutorial; noted a reply in another thread. The short guide below is a compact, up-to-date starter: core concepts, a minimal hands-on example, common pitfalls, and authoritative resources to follow for deeper study.

A minimal program using Foundation (save as main.m):

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        NSLog(@"Hello, Objective-C");
    }
    return 0;
}

Compile and run from Terminal (macOS with clang/LLVM):

clang -fobjc-arc -framework Foundation main.m -o hello
./hello

Key topics to learn next in practical order: basic C and pointers; Objective-C syntax (@interface/@implementation, message sends like [obj method], property/dot syntax); Foundation classes (NSString, NSArray, NSDictionary); memory management differences (ARC vs manual retain/release); categories, protocols, and blocks; and then platform frameworks (UIKit for iOS, AppKit for macOS). For projects that mix C++ and Objective-C, use the .mm extension (Objective-C++).

Common troubleshooting notes: linker errors often mean a missing framework (add -framework Foundation for CLI apps). Forgetting an @autoreleasepool in a command-line app can cause leaks. Legacy tutorials may show manual retain/release—use ARC for new code or annotate files that require MRR. Objective-C/Swift bridging benefits from nullability annotations when migrating.

Authoritative references and deeper tutorials: The Objective-C Programming Language (Apple) and practical articles at objc.io. This note is intended to be a concise, self-contained starting point complementary to the replies already posted by forum members.
