Meet Xcode: Your iOS IDE

Xcode is Apple's all-in-one IDE: you write code, design UI, debug, and ship to the App Store, all from one tool.

Download & Install Xcode

Grab Xcode free from the Mac App Store. Just note it is 30+ GB, so clear some disk space first.

Your First Project: Setup

Launch Xcode and choose Create a new Xcode project — or File > New > Project if it is already open.

Selecting Project Template

Pick the iOS > App template. It scaffolds a single view controller — the perfect minimal base for learning.

Name Your App & Configure

Configure your project: Product Name and Organization Identifier form your Bundle Identifier. Crucially, set Language to Objective-C.

Exploring Project Structure

Xcode opens with the Project Navigator on the left, listing files like AppDelegate, SceneDelegate, ViewController, main.m, and the storyboard.

The App's Entry Point: main.m

Every app starts at main.m, the entry point — just like main() in C. It boots the app object and your app delegate.

    #import <UIKit/UIKit.h>
    #import "AppDelegate.h"

    int main(int argc, char * argv[]) {
        NSString * appDelegateClassName;
        @autoreleasepool {
            // Setup code that might create objects goes here.
            appDelegateClassName = NSStringFromClass([AppDelegate class]);
        }
        return UIApplicationMain(argc, argv, nil, appDelegateClassName);
    }

App & Scene Delegates

The App Delegate manages your whole app lifecycle; the Scene Delegate (iOS 13+) manages each individual window or scene.

UI: View Controllers & Storyboards

Your UI lives in View Controllers (the code for one screen) and the storyboard, a visual editor for laying out elements.

Build & Run on a Simulator

To see your app, pick a simulator like iPhone 15 Pro and hit Run. Xcode builds and launches it as a virtual iPhone on your Mac.

Quick Check: Xcode Setup

Let's test your understanding of setting up an Objective-C project in Xcode.

Recap: Your Xcode Journey Begins

Recap: you installed Xcode, created an Objective-C app, met key files like main.m and the delegates, and ran it on a simulator.
