Integration

CocoaPods

You can use CocoaPods to install MultiPeer by adding it to your Podfile:

pod 'MultiPeer'

Carthage

You can use Carthage to install MultiPeer by adding it to your Cartfile:

github "dingwilson/MultiPeer"

Swift Package Manager

For SPM, add the following to your package dependencies:

.package(url: "https://github.com/dingwilson/MultiPeer.git", .upToNextMinor(from: "0.0.0"))

Usage

To get started, import MultiPeer.

import MultiPeer

Then, simply initialize MultiPeer with the name of your session (serviceType). There are two modes of connections (advertiser and browser). To utilize both, simply use .autoConnect().

MultiPeer.instance.initialize(serviceType: "demo-app")
MultiPeer.instance.autoConnect()

Any data transmitted by MultiPeer will always be accompanied by a numerical "type", to ensure other peers know what kind of data is being received, and how to properly process it. You can manage this by creating a UInt32 enum, as shown below:

enum DataType: UInt32 {
  case string = 1
  case image = 2
  // ...
}

To send data, simply use the .send(object: type:) function:

MultiPeer.instance.send(object: "Hello World!", type: DataType.string.rawValue)

To receive data, we must conform to the MultiPeerDelegate protocol:

func multiPeer(didReceiveData data: Data, ofType type: UInt32) {
  switch type {
    case DataType.string.rawValue:
      let string = data.convert() as! String
      // do something with the received string
      break;
      		
    case DataType.image.rawValue:
      let image = UIImage(data: data)
      // do something with the received UIImage
      break;
      		
    default:
      break;
  }
}

func multiPeer(connectedDevicesChanged devices: [String]) {
}

Finally, ensure that you set the MultiPeer delegate.

MultiPeer.instance.delegate = self

Congratulations! You have successfully sent data using MultiPeer! For more detailed information (including details of other functions), please see the docs.
