How To Use Swifter.jl and AppConsole

• https://github.com/wookay/Swifter.jl

• https://github.com/wookay/AppConsole

1. AppConsole

• It's an RPC Server written in Swift

Demo project

• Install prerequisites using CocoaPods.

  AppConsole/Demo/ViewController $ pod install

Running the sample workspace on Xcode

• Open and run AppConsole/Demo/ViewController/ViewController.xcworkspace

// part of ViewController.swift
class ViewController: UIViewController {
    @IBOutlet var label: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        label.text = AppConsole(initial: self).run()
    }

    ...

• When running the project successfully, could get the output like this.

  AppConsole.swift #28 run AppConsole Server has started on http://localhost:8080

2. Swifter.jl

• It's an RPC Client written in Julia

Install Julia

• Download the Julia (0.4.5) and run http://julialang.org/downloads/

Install Swifter.jl

julia> Pkg.add("Swifter")

Initial

• Inital connect to the endpoint.

julia> using Swifter

julia> vc = initial("http://localhost:8080")
<ViewController.ViewController: 0x7f8dda71e4a0>

Query

• Query getter, setter expressions using @query macro.

julia> @query vc.view
<UIView: 0x7f8dda68fde0; frame = (0 0; 320 568); autoresize = W+H; layer = <CALayer: 0x7f8dda690160>>

• Query mode (> key) for REPL

julia> @query vc.view
<UIView: 0x7f8dda68fde0; frame = (0 0; 320 568); autoresize = W+H; layer = <CALayer: 0x7f8dda690160>>

Swifter> vc.view
<UIView: 0x7f8dda68fde0; frame = (0 0; 320 568); autoresize = W+H; layer = <CALayer: 0x7f8dda690160>>

IJulia

• Swifter.jl supports Jupyter mime types.

• To run the Jupyter interactive environment, install IJulia.

  julia> Pkg.add("IJulia")
  julia> using IJulia
  julia> notebook()
