CountryFlags

Zero-Dependency SwiftUI components to dynamically generate country flags from ISO codes (e.g., "TN" → 🇹🇳). No image assets, no external libraries – just native Swift/SwiftUI.

🚀 Key Advantages

• 🏳️ Instant Flag Generation - from 2-letter codes
• 🧩 No Assets Needed – Flags generated at runtime via Unicode
• 📦 No Pods/SPM – 100% self-contained SwiftUI
• 🖥 System-Native – Matches Apple’s emoji rendering
• 🎚 Fully Scalable – Vector-perfect at any size
• 📋 Copy-Paste Friendly - Ready-to-use components

Core Implementation

1. Unicode Flag Generator

extension String {
    /// Converts ISO 3166-1 codes to emoji flags ("TN" → "🇹🇳")
    func toFlag() -> String {
        guard self.count == 2 else { return "" }
        return self.uppercased()
            .unicodeScalars
            .map { UnicodeScalar(127397 + $0.value)! }
            .reduce("") { $0 + String($1) }
    }
}

Why This Solution Stands Out

Method	Storage	Rendering	Dependencies
This Solution	0KB	Vector	None
Image Assets	~200KB*	Bitmap	None
Flag Libraries	1MB+	Mixed	SPM/CocoaPods

^{*Estimated size for 250+ flag PNGs at 2x resolution}

Requirements

• iOS 15.0+
• Xcode 13+
