Mobile & Gaming Development

Quick Start

Swift Basics (iOS)

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var label: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()
        label.text = "Hello, World!"
    }

    @IBAction func buttonTapped(_ sender: UIButton) {
        label.text = "Button tapped!"
    }
}

SwiftUI (Modern iOS)

import SwiftUI

struct ContentView: View {
    @State var count = 0

    var body: some View {
        VStack {
            Text("Count: \(count)")
                .font(.title)

            Button("Increment") {
                count += 1
            }
            .padding()
        }
    }
}

Kotlin Basics (Android)

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val button = findViewById<Button>(R.id.button)
        button.setOnClickListener {
            Toast.makeText(this, "Button clicked!", Toast.LENGTH_SHORT).show()
        }
    }
}

React Native

import React, { useState } from 'react';
import { View, Text, TouchableOpacity, StyleSheet } from 'react-native';

export default function App() {
    const [count, setCount] = useState(0);

    return (
        <View style={styles.container}>
            <Text>Count: {count}</Text>
            <TouchableOpacity
                style={styles.button}
                onPress={() => setCount(count + 1)}
            >
                <Text>Increment</Text>
            </TouchableOpacity>
        </View>
    );
}

const styles = StyleSheet.create({
    container: { flex: 1, justifyContent: 'center' },
    button: { padding: 10, backgroundColor: '#007AFF' }
});

Flutter

import 'package:flutter/material.dart';

void main() {
    runApp(MyApp());
}

class MyApp extends StatefulWidget {
    @override
    _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
    int count = 0;

    @override
    Widget build(BuildContext context) {
        return MaterialApp(
            home: Scaffold(
                appBar: AppBar(title: Text('Counter')),
                body: Center(
                    child: Column(
                        children: [
                            Text('Count: $count'),
                            ElevatedButton(
                                onPressed: () => setState(() => count++),
                                child: Text('Increment'),
                            )
                        ],
                    )
                ),
            ),
        );
    }
}
