DIGIPIN

🌍 📍 A Swift library for handling India Post's DIGIPIN (Digital Postal Index Number) system - encode any location in India into a simple 10-character code.

🗺️ Geographic Encoding

The DIGIPIN framework provides tools to generate and decode DIGIPIN codes - India Post's revolutionary geographic encoding system. It enables precise location representation through a simple 10-character alphanumeric code, covering all of India's territory with high precision.

Add the DIGIPIN product to your target's dependencies:

.target(
    name: "YourTarget",
    dependencies: [
        .product(name: "DIGIPIN", package: "digipin")
    ]
)

Quick Example

import DIGIPIN

// Generate a DIGIPIN code
let digipin = DIGIPIN()
let coordinate = Coordinate(latitude: 28.622788, longitude: 77.213033) // Dak Bhawan (official example)

let code = try digipin.generateDIGIPIN(for: coordinate)
print(code) // "39J-49L-L8T4"

// Convert back to coordinates
let location = try digipin.coordinate(from: "39J-49L-L8T4")
print("Lat: \(location.latitude), Long: \(location.longitude)")

See the framework's documentation for detailed information and guides.

📍 Geographic Coverage
