DarkLightning is a lightweight Swift library to allow data transmission between iOS/tvOS devices (Lightning port, Dock connector, USB-C) and OSX (USB) at 480MBit - without jailbreaking your iOS/tvOS device. It uses the usbmuxd service on OSX to open a TCP socket connection to the iOS/tvOS device.
- iOS/tvOS und OSX implementations to transmit data with up to 480 MBit via USB between iOS/tvOS and OSX
- Simulator connection for debugging with iOS/tvOS Simulator
- Information on connected iOS/tvOS devices on OSX
- Callbacks for newly connected and disconnected iOS/tvOS devices on OSX
- iOS 8.0+
- tvOS 9.0+
- Mac OS X 10.10+
- Xcode 8.3
DarkLightning is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "DarkLightning"There are three subspecs included: iOS, tvOS and OSX. CocoaPods automatically selects the correct subspec depending on the platform you are developing for. That means that pod "DarkLightning" and pod "DarkLightning/iOS" have the same effect if you are developing an iOS app.
The basic procedure to open a connection between iOS/tvOS and OSX looks like this:
- Start a
DevicePorton a port on iOS/tvOS - Discover the device on OSX
- Establish a connection to the previously defined port on iOS/tvOS
You can send an arbitrary amount of bytes between iOS/tvOS and OSX. The data are being sent using TCP.
let port = DevicePort(delegate: MyPortDelegate())
port.open()public func port(port: DarkLightning.Port, didReceiveData data: OOData) {
}let data = "Hello World".data(using: .utf8)
port.writeData(data: data!)let daemon = USBDaemon(delegate: MyDaemonDelegate(), deviceDelegate: MyDeviceDelegate())
daemon.start()As soon as you plug in or out an iOS/tvOS device to your Mac you will receive a callback on the corresponding delegate method (daemon(_:didAttach:) or daemon(_:didDetach:)) of USBDaemon. You will also receive a callback on daemon(_:didAttach:) for every iOS/tvOS device that was already attached to OSX when you started the discovery via daemon.start().
// Called for every device that already is or will be attached to the system
public func daemon(_ daemon: Daemon, didAttach device: Device) {
}
// Called for every iOS/tvOS device that has been detached from the system
public func daemon(_ daemon: Daemon, didDetach device: Device) {
}With the help of a discovered Device you can now establish a connection to your iOS/tvOS app.
device.connect()When you are done with the connection make sure to close it properly.
device.disconnect()public func device(_ device: Device, didReceiveData data: OOData) {
}let data = "Hello World".data(using: .utf8)
device.writeData(data: data!)The Example (see Example folder) is a simple messenger that uses DarkLightning to send text messages from iOS/tvOS to OSX and vice versa.
Note: The iOS/tvOS application needs to be launched before the OSX part. The OSX part will try to connect to the first device that has been attached via USB. If there are no attached devices it tries to connect to the iOS/tvOS Simulator.
