A snippet showing how to decode the data and store it in an array within the ARSupportBroadcastViewController

touchPoints+Snippet.swift

default:
    if debug {
        print("touch points msg recieved")
    }
    // convert data string into an array -- using given pattern as delimeter
    let arrayOfPoints = dataAsString.components(separatedBy: "), (")

    if debug {
        print("arrayOfPoints: \(arrayOfPoints)")
    }

    for pointString in arrayOfPoints {
        let pointArray: [String] = pointString.components(separatedBy: ", ")
        // make sure we have 2 points and convert them from String to number
        if pointArray.count == 2, let x = NumberFormatter().number(from: pointArray[0]), let y = NumberFormatter().number(from: pointArray[1]) {
            let remotePoint: CGPoint = CGPoint(x: CGFloat(truncating: x), y: CGFloat(truncating: y))
            self.remotePoints.append(remotePoint)
            if debug {
                print("POINT - \(pointString)")
                print("CGPOINT: \(remotePoint)")
            }
        }
    }
