IMNetworkReachability

IMNetworkReachability is a reachability framework. It is designed to help you interface with network activity events. It allows you to monitor network state synchronously and asynchronously.

• Requirements
• Installation
• Usage

Requirements

• iOS 8.0+ / macOS 10.9+ / tvOS 9.0+
• Xcode 9.0
• Swift 4.0

Installation

IMNetworkReachability supports multiple methods for installing the library in a project.

Installation with CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like IMNetworkReachability in your projects. See the "Getting Started" guide for more information. You can install it with the following command:

$ gem install cocoapods

Podfile

To integrate IMNetworkReachability into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'

target 'iOS' do
  platform :ios, '8.0'
  use_frameworks!

  pod 'IMNetworkReachability', '~> 0.2.0'

end

target 'macOS' do
  platform :osx, '10.9'
  use_frameworks!

  pod 'IMNetworkReachability', '~> 0.2.0'

end

target 'tvOS' do
  platform :tvos, '9.0'
  use_frameworks!

  pod 'IMNetworkReachability', '~> 0.2.0'

end

Then, run the following command:

$ pod install

Installation with Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate IMNetworkReachability into your Xcode project using Carthage, specify it in your Cartfile:

github "vanyaland/IMNetworkReachability" ~> 0.2.0

Run carthage to build the framework and drag the built IMNetworkReachability.framework into your Xcode project.

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but IMNetworkReachability does support its use on supported platforms.

Once you have your Swift package set up, adding IMNetworkReachability as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/vanyaland/IMNetworkReachability.git", from: "0.2.0"),
]

Manually

If you prefer not to use any of the aforementioned dependency managers, you can integrate IMNetworkReachability into your project manually.

Embedded Framework

• Open up Terminal, cd into your top-level project directory, and run the following command "if" your project is not initialized as a git repository:

  $ git init

• Add IMNetworkReachability as a git submodule by running the following command:

  $ git submodule add https://github.com/vanyaland/IMNetworkReachability.git

• Open the new IMNetworkReachability folder, and drag the IMNetworkReachability.xcodeproj into the Project Navigator of your application's Xcode project.

  It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter.

• Select the IMNetworkReachability.xcodeproj in the Project Navigator and verify the deployment target matches that of your application target.

• Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar.

• In the tab bar at the top of that window, open the "General" panel.

• Click on the + button under the "Embedded Binaries" section.

• You will see two different IMNetworkReachability.xcodeproj folders each with two different versions of the IMNetworkReachability.framework nested inside a Products folder.

  It does not matter which Products folder you choose from, but it does matter whether you choose the top or bottom IMNetworkReachability.framework.

• Select the top IMNetworkReachability.framework for iOS and the bottom one for OS X.

  You can verify which one you selected by inspecting the build log for your project. The build target for IMNetworkReachability will be listed as either IMNetworkReachability_iOS, IMNetworkReachability_macOS or IMNetworkReachability_tvOS.

• And that's it!

  The IMNetworkReachability.framework is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.

Usage

Synchronously

let reachability = IMNetworkReachability("www.google.com")

switch reachability.isReachable() {
  case .reachable:
    print("Reachable")
  case .offline:
    print("Offline")
  case .error(let error):
    print("Failed to check for a network reachability, error: \(error)")
}

Closures

// Declare this property where it won't go out of scope relative to your listener
let reachability = IMNetworkReachability("www.google.com")

reachability.startListening { (result) in
// this is called on a main thread
  switch result {
    case .reachable:
      print("Reachable")
    case .offline:
      print("Offline")
    case .error(let error):
      print("Failed to check for a network reachability, error: \(error)")
  }
}

and for stopping notifications

reachability.stopListening()

Also, don't forget to enable network access on macOS.
