Function signatures are pretty much similar to those in CocoaAsyncSocket because I implemented this framework by learning the source code of CocoaAsyncSocket. The initial idea to build this framework is driven by the need of network library to communicate with KEXT (NKE) to re-write my [Proximac](https://github.com/csujedihy/proximac) project but none of frameworks I found in github supports that. Thus, I decided to implemented my own framework to do so. 14 | 15 | **Note:** This framework is still under active development. It only passes my unit tests and might have various bugs. 16 | 17 | ## Features 18 | ### Full Delegate Support 19 | 20 | * every operation invokes a call to your delagate method. 21 | 22 | ### IPv6 Support 23 | 24 | * listens only on IPv6 protocol but **accepts both** IPv4 and IPv6 incoming connections. 25 | * conforms to Apple's new App Store restriction on IPv6 only environment with NAT64/DNS64. 26 | 27 | ### DNS Enabled 28 | 29 | * takes advantage of sythesized IPv6 address introduced in `iOS 9` and `OS X 10.11` for better IPv6 support. 30 | * uses GCD to do DNS concurrently and connect to the first reachable address. 31 | 32 | 33 | ### KEXT Bi-directional Interaction 34 | 35 | * takes a bundle ID to interact with your KEXT like TCP stream. 36 | 37 | ## Using SwiftDSSocket 38 | 39 | ### Including in your project 40 | 41 | #### Swift Package Manager 42 | 43 | To include SwiftDSSocket into a Swift Package Manager package, add it to the `dependencies` attribute defined in your `Package.swift` file. For example: 44 | 45 | ``` 46 | dependencies: [ 47 | .Package(url: "https://github.com/csujedihy/SwiftDSSocket", "x.x.x") 48 | ] 49 | ``` 50 | 51 | #### CocoaPods 52 | To include SwiftDSSocket in a project using CocoaPods, you just add `SwiftDSSocket` to your `Podfile`, for example: 53 | 54 | ``` 55 | target 'MyApp' do 56 | use_frameworks! 57 | pod 'SwiftDSSocket' 58 | end 59 | ``` 60 | 61 | #### Carthage 62 | To include SwiftDSSocket in a project using Carthage, add a line to your `Cartfile` with the GitHub organization and project names and version. For example: 63 | 64 | ``` 65 | github "csujedihy/SwiftDSSocket" 66 | ``` 67 | 68 | ### Documentation 69 | [https://csujedihy.github.io/SwiftDSSocket/](https://csujedihy.github.io/SwiftDSSocket/) 70 | 71 | ### Example: 72 | 73 | The following example creates a default `SwiftDSSocket` instance and then *immediately* starts listening on port `9999` and echoes back everything sent to this server. 74 | 75 | You can simply use `telnet 127.0.0.1 9999` to connect to this server and send whatever you want. 76 | 77 | ```swift 78 | import Cocoa 79 | import SwiftDSSocket 80 | 81 | class ViewController: NSViewController { 82 | var server: SwiftDSSocket? 83 | var newClient: SwiftDSSocket? 84 | let ServerTag = 0 85 | 86 | override func viewDidLoad() { 87 | super.viewDidLoad() 88 | server = SwiftDSSocket(delegate: self, delegateQueue: .main, type: .tcp) 89 | try? server?.accept(onPort: 9999) 90 | } 91 | } 92 | 93 | 94 | extension ViewController: SwiftDSSocketDelegate { 95 | func socket(sock: SwiftDSSocket, didAcceptNewSocket newSocket: SwiftDSSocket) { 96 | newClient = newSocket 97 | newSocket.readData(tag: ServerTag) 98 | } 99 | 100 | func socket(sock: SwiftDSSocket, didRead data: Data, tag: Int) { 101 | sock.write(data: data, tag: ServerTag) 102 | sock.readData(tag: ServerTag) 103 | } 104 | } 105 | 106 | ``` 107 | 108 | **Tips:** Check out `Demo` folder to see more examples for different environments. 109 | -------------------------------------------------------------------------------- /SwiftDSSocket.podspec: -------------------------------------------------------------------------------- 1 | Pod::Spec.new do |s| 2 | s.name = "SwiftDSSocket" 3 | s.version = "0.1.2" 4 | s.summary = "DispatchSource based sockets framework written in pure Swift 3.1" 5 | s.homepage = "https://github.com/csujedihy/SwiftDSSocket" 6 | s.license = "MIT" 7 | s.author = { "jedihy" => "csujedi@gmail.com" } 8 | s.social_media_url = "https://github.com/csujedihy" 9 | s.ios.deployment_target = "9.0" 10 | s.osx.deployment_target = "10.10" 11 | s.source = { :git => "https://github.com/csujedihy/SwiftDSSocket.git", :tag => "#{s.version}" } 12 | s.source_files = "Sources/**/*.swift" 13 | s.requires_arc = true 14 | s.xcconfig = { 'SWIFT_VERSION' => '3.1' } 15 | end 16 | -------------------------------------------------------------------------------- /SwiftDSSocket.xcodeproj/SwiftDSSocketTests_Info.plist: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | CFBundleDevelopmentRegion 5 | en 6 | CFBundleExecutable 7 | $(EXECUTABLE_NAME) 8 | CFBundleIdentifier 9 | $(PRODUCT_BUNDLE_IDENTIFIER) 10 | CFBundleInfoDictionaryVersion 11 | 6.0 12 | CFBundleName 13 | $(PRODUCT_NAME) 14 | CFBundlePackageType 15 | BNDL 16 | CFBundleShortVersionString 17 | 1.0 18 | CFBundleSignature 19 | ???? 20 | CFBundleVersion 21 | $(CURRENT_PROJECT_VERSION) 22 | NSPrincipalClass 23 | 24 | 25 | 26 | -------------------------------------------------------------------------------- /SwiftDSSocket.xcodeproj/SwiftDSSocket_Info.plist: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | CFBundleDevelopmentRegion 6 | en 7 | CFBundleExecutable 8 | $(EXECUTABLE_NAME) 9 | CFBundleIdentifier 10 | $(PRODUCT_BUNDLE_IDENTIFIER) 11 | CFBundleInfoDictionaryVersion 12 | 6.0 13 | CFBundleName 14 | $(PRODUCT_NAME) 15 | CFBundlePackageType 16 | FMWK 17 | CFBundleShortVersionString 18 | 0.0.4 19 | CFBundleSignature 20 | ???? 21 | CFBundleVersion 22 | $(CURRENT_PROJECT_VERSION) 23 | NSPrincipalClass 24 | 25 | 26 | 27 | -------------------------------------------------------------------------------- /SwiftDSSocket.xcodeproj/project.pbxproj: -------------------------------------------------------------------------------- 1 | // !$*UTF8*$! 2 | { 3 | archiveVersion = 1;

SwiftDSSocket

65 |

Overview

66 | 67 |

SwiftDSSocket is a purely swift based asynchronous socket framework built atop DispatchSource. Function signatures are pretty much similar to those in CocoaAsyncSocket because I implemented this framework by learning the source code of CocoaAsyncSocket. The initial idea to build this farmework is driven by the need of network library to communicate with KEXT (NKE) to re-write my Proximac project but none of frameworks I found in github supports that. Thus, I decided to implemented my own framework to do so.

68 | 69 |

Note: This framework is still under active development. It only passes my unit tests and might have various bugs.

70 |

Features

71 |

Full Delegate Support

72 | 73 |
    74 |
  • every operation invokes a call to your delagate method.
    • 75 |
76 |

IPv6 Support

77 | 78 |
    79 |
  • listens only on IPv6 protocol but accepts both IPv4 and IPv6 incoming connections.
    • 80 |
  • conforms to Apple’s new App Store restriction on IPv6 only environment with NAT64/DNS64.
    • 81 |
82 |

DNS Enabled

83 | 84 |
    85 |
  • takes advantage of sythesized IPv6 address introduced in iOS 9 and OS X 10.11 for better IPv6 support.
    • 86 |
  • uses GCD to do DNS concurrently and connect to the first reachable address.
    • 87 |
88 |

KEXT Bi-directional Interaction

89 | 90 |
    91 |
  • takes a bundle ID to interact with your KEXT like TCP stream.
    • 92 |
93 |

Using SwiftDSSocket

94 |

Including in your project

95 |

Swift Package Manager

96 | 97 |

To include SwiftDSSocket into a Swift Package Manager package, add it to the dependencies attribute defined in your Package.swift file. For example:

98 | 
    dependencies: [
 99 |         .Package(url: "https://github.com/csujedihy/SwiftDSSocket", "x.x.x")
100 |     ]
101 |
102 |

CocoaPods

103 | 104 |

To include SwiftDSSocket in a project using CocoaPods, you just add SwiftDSSocket to your Podfile, for example:

105 | 
    target 'MyApp' do
106 |         use_frameworks!
107 |         pod 'SwiftDSSocket'
108 |     end
109 |
110 |

Carthage

111 | 112 |

To include SwiftDSSocket in a project using Carthage, add a line to your Cartfile with the GitHub organization and project names and version. For example:

113 | 
    github "csujedihy/SwiftDSSocket"
114 |
115 |

Documentation

116 | 117 |

https://csujedihy.github.io/SwiftDSSocket/

118 |

Example:

119 | 120 |

The following example creates a default SwiftDSSocket instance and then immediately starts listening on port 9999 and echoes back everything sent to this server.

121 | 122 |

You can simply use telnet 127.0.0.1 9999 to connect to this server and send whatever you want.

123 | 
import Cocoa
124 | import SwiftDSSocket
125 | 
126 | class ViewController: NSViewController {
127 |   var server: SwiftDSSocket?
128 |   var newClient: SwiftDSSocket?
129 |   let ServerTag = 0
130 | 
131 |   override func viewDidLoad() {
132 |     super.viewDidLoad()
133 |     server = SwiftDSSocket(delegate: self, delegateQueue: .main, type: .tcp)
134 |     try? server?.accept(onPort: 9999)
135 |   }
136 | }
137 | 
138 | 
139 | extension ViewController: SwiftDSSocketDelegate {
140 |   func socket(sock: SwiftDSSocket, didAcceptNewSocket newSocket: SwiftDSSocket) {
141 |     newClient = newSocket
142 |     newSocket.readData(tag: ServerTag)
143 |   }
144 | 
145 |   func socket(sock: SwiftDSSocket, didRead data: Data, tag: Int) {
146 |     sock.write(data: data, tag: ServerTag)
147 |     sock.readData(tag: ServerTag)
148 |   }
149 | }
150 | 
151 |
152 | 153 |

SwiftDSSocket

65 |

Overview

66 | 67 |

SwiftDSSocket is a purely swift based asynchronous socket framework built atop DispatchSource. Function signatures are pretty much similar to those in CocoaAsyncSocket because I implemented this framework by learning the source code of CocoaAsyncSocket. The initial idea to build this farmework is driven by the need of network library to communicate with KEXT (NKE) to re-write my Proximac project but none of frameworks I found in github supports that. Thus, I decided to implemented my own framework to do so.

68 | 69 |

Note: This framework is still under active development. It only passes my unit tests and might have various bugs.

70 |

Features

71 |

Full Delegate Support

72 | 73 |
    74 |
  • every operation invokes a call to your delagate method.
    • 75 |
76 |

IPv6 Support

77 | 78 |
    79 |
  • listens only on IPv6 protocol but accepts both IPv4 and IPv6 incoming connections.
    • 80 |
  • conforms to Apple’s new App Store restriction on IPv6 only environment with NAT64/DNS64.
    • 81 |
82 |

DNS Enabled

83 | 84 |
    85 |
  • takes advantage of sythesized IPv6 address introduced in iOS 9 and OS X 10.11 for better IPv6 support.
    • 86 |
  • uses GCD to do DNS concurrently and connect to the first reachable address.
    • 87 |
88 |

KEXT Bi-directional Interaction

89 | 90 |
    91 |
  • takes a bundle ID to interact with your KEXT like TCP stream.
    • 92 |
93 |

Using SwiftDSSocket

94 |

Including in your project

95 |

Swift Package Manager

96 | 97 |

To include SwiftDSSocket into a Swift Package Manager package, add it to the dependencies attribute defined in your Package.swift file. For example:

98 | 
    dependencies: [
 99 |         .Package(url: "https://github.com/csujedihy/SwiftDSSocket", "x.x.x")
100 |     ]
101 |
102 |

CocoaPods

103 | 104 |

To include SwiftDSSocket in a project using CocoaPods, you just add SwiftDSSocket to your Podfile, for example:

105 | 
    target 'MyApp' do
106 |         use_frameworks!
107 |         pod 'SwiftDSSocket'
108 |     end
109 |
110 |

Carthage

111 | 112 |

To include SwiftDSSocket in a project using Carthage, add a line to your Cartfile with the GitHub organization and project names and version. For example:

113 | 
    github "csujedihy/SwiftDSSocket"
114 |
115 |

Documentation

116 | 117 |

https://csujedihy.github.io/SwiftDSSocket/

118 |

Example:

119 | 120 |

The following example creates a default SwiftDSSocket instance and then immediately starts listening on port 9999 and echoes back everything sent to this server.

121 | 122 |

You can simply use telnet 127.0.0.1 9999 to connect to this server and send whatever you want.

123 | 
import Cocoa
124 | import SwiftDSSocket
125 | 
126 | class ViewController: NSViewController {
127 |   var server: SwiftDSSocket?
128 |   var newClient: SwiftDSSocket?
129 |   let ServerTag = 0
130 | 
131 |   override func viewDidLoad() {
132 |     super.viewDidLoad()
133 |     server = SwiftDSSocket(delegate: self, delegateQueue: .main, type: .tcp)
134 |     try? server?.accept(onPort: 9999)
135 |   }
136 | }
137 | 
138 | 
139 | extension ViewController: SwiftDSSocketDelegate {
140 |   func socket(sock: SwiftDSSocket, didAcceptNewSocket newSocket: SwiftDSSocket) {
141 |     newClient = newSocket
142 |     newSocket.readData(tag: ServerTag)
143 |   }
144 | 
145 |   func socket(sock: SwiftDSSocket, didRead data: Data, tag: Int) {
146 |     sock.write(data: data, tag: ServerTag)
147 |     sock.readData(tag: ServerTag)
148 |   }
149 | }
150 | 
151 |
152 | 153 |
