ReachabilityX is built using NWPathMonitor from Apple's Network framework to provide an easy way to observe the network changes for SwiftUI.

- Swift 5.3+
Add it as a dependency within your Package.swift,
dependencies: [
.package(url: "https://github.com/dscyrescotti/ReachabilityX", from: "1.0.0")
]
Currently, ReachabilityX can only be installed via Swift Package Manager.
ReachabilityX comes with ReachabilityView that exposes Reachability object supplied from its parent or ancestor. It is pretty handy to use when network changes are needed to observe across multiple views.
Firstly, you need to create an instance of Reachability inside the entry point of an app for the purpose of sharing it across multiple views via environmentObject(_:).
@main
struct TestApp: App {
@ObservedObject var reachability: Reachability = .init()
var body: some Scene {
WindowGroup {
ContentView()
.environmentObject(reachability)
.onAppear {
reachability.start()
}
}
}
}Now, you can easily implement your presentation logic inside ReachabilityView and also implement your business logic using onChangeStatus(action:), onChangeInterfaceType(action:) and onChangePath(action:).
struct ContentView: View {
var body: some View {
ReachabilityView { (status: Status) in
// some presentation logic
}
.onChangeStatus { status in
// some business logic associated with status changes
}
.onChangeInterfaceType { interfaceType in
// some business logic associated with interface type changes
}
.onChangePath { path in
// some business logic associated with path changes
}
}
}ReachabilityView comes with a couple of initializers that allows you to construct your desired views inside closures with different parameters.
// use it when you are only interested in status
ReachabilityView { (status: Status) in
// some presentation logic associated with status changes
}
// use it when you are only interested in interface type
ReachabilityView { (interfaceType: InterfaceType) in
// some presentation logic associated with interface changes
}
// use it when you are interested in both of status and interface type
ReachabilityView { (status: Status, interfaceType: InterfaceType) in
// some presentation logic associated with status and interface type changes
}
// use it when you need to know the whole network path object
ReachabilityView { (path: NWPath) in
// some presentation logic associated with network path
}ReachabiliyX also allows you to create your own Reachability instance by declaring inside SwiftUI view to observe the network changes.
struct ContentView: View {
@StateObject var reachability: Reachability = .init()
var body: some View {
Group {
switch reachability.status {
case .satisfied: Text("Connected!")
default: Text("Not Connected!")
}
}
.onAppear {
reachability.start()
}
.onDisappear {
reachability.stop()
}
.onChangeInterfaceType(reachability) { interfaceType in
// some business logic
}
}
}To obtain network path updates, you need to call start() method to begin observing network changes. If you want to stop observing changes, you have to call stop() method. This will no longer monitor any network changes.
