Network Scanner

A powerful network scanning utility for iOS, built with SwiftUI and MVVM architecture. The application provides comprehensive tools for discovering devices on your Local Area Network (LAN) using MMLanScan and detecting nearby Bluetooth peripherals with CoreBluetooth. It features a modern interface with Lottie animations and robust data persistence using CoreData.

⚠️ Important

MAC addresses and device brands are not available on iOS 11+ due to Apple's privacy restrictions. This is a system-level limitation affecting all network scanning applications.

✨ Features

• 📡 LAN Scanner: Quickly detect all devices connected to your Wi-Fi network using the robust MMLanScan library.
• 🔵 Bluetooth Scanner: Discover nearby Bluetooth devices, view their signal strength (RSSI), connection status, and explore advertised services using CoreBluetooth.
• 💾 History & Persistence: Automatically save your scan sessions to a local CoreData database. Filter results by time and device name for easy access.
• 📱 Device Details: View detailed technical information about every discovered device.
• 🎨 Modern UI: A clean, responsive interface enhanced with smooth Lottie animations, including a dedicated Launch Screen.
• 👆 Gestures & Refresh: Manage data intuitively with swipe-to-delete gestures and pull-to-refresh functionality.
• ⚡️ Fast Search: Super fast search capability powered directly by the database.
• 🛡️ Robust Error Handling: Comprehensive error handling to ensure a smooth user experience.

• CoreData: For local data persistence of scan history.
• CoreBluetooth: For interacting with Bluetooth Low Energy devices.
• MMLanScan: A powerful library for network discovery.
• Lottie: For rendering high-quality vector animations.
• CocoaPods & SPM: Used for dependency management.
