# Socket.IO-Client-Swift
Socket.IO-client for iOS/OS X.

## Example
```swift
import SocketIO

let manager = SocketManager(socketURL: URL(string: "http://localhost:8080")!, config: [.log(true), .compress])
let socket = manager.defaultSocket

socket.on(clientEvent: .connect) {data, ack in
    print("socket connected")
}

socket.on("currentAmount") {data, ack in
    guard let cur = data[0] as? Double else { return }
    
    socket.emitWithAck("canUpdate", cur).timingOut(after: 0) {data in
        if data.first as? String ?? "passed" == SocketAckStatus.noAck {
            // Handle ack timeout 
        }

        socket.emit("update", ["amount": cur + 2.50])
    }

    ack.with("Got your currentAmount", "dude")
}

socket.connect()
```

## Installation
Requires Swift 4/5 and Xcode 10.x

### Swift Package Manager
Add the project as a dependency to your Package.swift:
```swift
// swift-tools-version:4.2

import PackageDescription

let package = Package(
    name: "socket.io-test",
    products: [
        .executable(name: "socket.io-test", targets: ["YourTargetName"])
    ],
    dependencies: [
        .package(url: "https://github.com/socketio/socket.io-client-swift", .upToNextMinor(from: "16.1.1"))
    ],
    targets: [
        .target(name: "YourTargetName", dependencies: ["SocketIO"], path: "./Path/To/Your/Sources")
    ]
)
```

Then import `import SocketIO`.

### Carthage
Add this line to your `Cartfile`:
```
github "socketio/socket.io-client-swift" ~> 16.1.1
```

Run `carthage update --platform ios,macosx`.

Add the `Starscream` and `SocketIO` frameworks to your projects and follow the usual Carthage process.

### CocoaPods 1.0.0 or later
Create `Podfile` and add `pod 'Socket.IO-Client-Swift'`:

```ruby
use_frameworks!

target 'YourApp' do
    pod 'Socket.IO-Client-Swift', '~> 16.1.1'
end
```

Install pods:

```
$ pod install
```

Import the module:

Swift:
```swift
import SocketIO
```

Objective-C:

```Objective-C
@import SocketIO;
```
