Reachability

A new, clean and lean network interface reachability library written in Swift.

Remarks

Network reachability changes can be monitored using the built-in Combine publisher or an async stream.

While it is possible to create customised instances, a default shared instance is provided.

The native NWPathMonitor is used under the covers to provide the library functionality.

Basic Usage

Simple

import Reachability

if Reachability.shared.currentPath.isReachable {
    print("We are online")
} else {
    print("No internet")
}

SwiftUI

import SwiftUI
import Reachability

struct SomeView: View {
    @ObservedObject var reachability = Reachability.shared

    var body: some View {
        if reachability.currentPath.isReachable {
            // Show some data loaded from the internet
        } else {
            Text("No internet connection")
        }
    }
}

Using Combine

import Reachability

var subscriptions = Set<AnyCancellable>()

Reachability.shared.publisher
    .sink { path in
        if path.isReachable {
            print("We are online")
        } else {
            print("No internet")
        }
    }
    .store(in: &subscriptions)

Using AsyncStream

import Reachability

Task {
    for await path in Reachability.shared.stream {
        if path.isReachable {
            print("We are online")
        } else {
            print("No internet")
        }
    }
}

Installation

Reachability can be installed using Swift Package Manager, a dependency manager built into Xcode.

While in Xcode, go to File / Swift Packages / Add Package Dependency… and enter the package repository URL https://github.com/Alecrim/Reachability.git, then follow the instructions.

To remove the dependency, select the project and open Swift Packages (next to Build Settings).
