Personal note on how to setup launch images in RN when using RNN [iOS] (iPhone).

Preparation

Launch image sizes:

portrait

1. Retina HD 5.5" : 1242 x 2208 px
2. Retina HD 4.7" : 750 x 1334 px

function getLinkedListLength(A = [1,4,-1,3,2]) {
	let count = 0;
	let current = 0;

	while(current !== -1) {
    if (A.length < current)
      throw Error(`No link found for value: ${current}. Count: ${count}`); 
    
		current = A[current];
		count++;

const calculateDistance = (pointA, pointB) => {

  // http://www.movable-type.co.uk/scripts/latlong.html
  const lat1 = pointA.coordinate.latitude;
  const lon1 = pointA.coordinate.longitude;

  const lat2 = pointB.coordinate.latitude;
  const lon2 = pointB.coordinate.longitude;

  const R = 6371e3; // earth radius in meters
