// Sample using CoreMotion and SwiftUI to help understand how to use CMMotionManager and CoreMotion to get values of gravity, user acceleration, heading (2), attitude (pitch, roll, yaw), magnetic field
// based on this beautiful example https://github.com/gsachin/DynamicFontRandD/blob/e4f7cc611d1d23573b4026bcc291bee60bf60e91/FontTextStrok/WaveView.swift
// that uses BAFluidView https://github.com/antiguab/BAFluidView

import SwiftUI
import CoreMotion
let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()

struct WaveView: View {
