Creating Motion-sensing application Using Xcode;

I currently have 3 Xcode projects available: AirGuitar, Angular Rotation rate, Angle Detect

I need to combine this three projects to make a prototype app with:

1. Mapping 6 different angles (25, 14, 5, -5, -15, -25 degrees each) to 6 different guitar strings, each string with fixed note

2. Mapping the rotation rate (angular velocity) to the strumming force (velocity)

How could I possibly combine these projects by Threading in Swift? (maybe using dispatch queue?)

/////AirGuitar ViewController.swift code;

import UIKit

class ViewController: UIViewController {

var button1: Button1!

var button2: Button2!

var button3: Button3!

var button4: Button4!

var button5: Button5!

var button6: Sampler1!

override func viewDidLoad() {

super.viewDidLoad()

button1 = Button1()

button2 = Button2()

button3 = Button3()

button4 = Button4()

button5 = Button5()

button6 = Sampler1()

}

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

// Dispose of any resources that can be recreated.

}

@IBAction func button1Down(_ sender: UIButton) {

button1.play()

}

@IBAction func button2Down(_ sender: UIButton) {

button2.play()

}

@IBAction func button3Down(_ sender: UIButton) {

button3.play()

}

@IBAction func button4Down(_ sender: UIButton) {

button4.play()

}

@IBAction func button5Down(_ sender: UIButton) {

button5.play()

}

@IBAction func button6Down(_ sender: UIButton) {

button6.play()

}

// @IBAction func sampler1Up(_ sender: UIButton) {

// sampler1.stop()

// }

}
