How to Build Reusable SwiftUI Components

🔥 Stop Copy-Pasting UI Code in SwiftUI!

Your designer just changed the primary button color. Now you're hunting through 20+ files to update them manually... 😅

Sound familiar? Every SwiftUI developer has been there.

🚀 The Solution: Reusable Components

I just published the complete guide to building SwiftUI components that you'll actually want to reuse across your entire app.

🎯 What You'll Learn

🔘 Custom Button Component

• Multiple states (primary, secondary, destructive)
• Disabled states with proper styling
• Clean, consistent API design

🃏 Flexible Card Component

• Generic design that works with ANY content
• Multiple styles (elevated, flat, bordered)
• Consistent spacing and shadows

📝 Smart Input Fields

• Built-in validation (email, min length, custom rules)
• Proper error handling and display
• Modern @State vs @Binding patterns

🎨 Custom ViewModifiers

• Design system consistency
• Environment-aware styling
• One place to update, everywhere reflects changes

💡 Quick Preview

Instead of scattered button code like this:

// Scattered across different files... 😬
Button("Login") {
    // action
}
.font(.headline)
.foregroundColor(.white)
.padding()
.background(Color.blue)  // Designer changed this!
.cornerRadius(8)

You get clean, reusable components:

// Anywhere in your app ✨
CustomButton("Login", style: .primary) {
    // login action
}

CustomButton("Cancel", style: .secondary) {
    // cancel action  
}

CustomButton("Delete", style: .destructive) {
    // delete action
}

The magic? When your designer changes colors, you update ONE file and every button automatically updates! 🎉
