I decided to build an iOS app for my University's bus service that runs through the various campuses.

It was an interesting challenge as I had nothing but the printed timetables (http://www.nottingham.ac.uk/about/documents/903-times.pdf) to use as the data.

Thus I had to come with a suitable data structure that would complement the design & user experience i had in mind for the app.

I also decided to take the challenge of writing the app in swift. This project has helped me get to up speed with swift really quickly.

	<?php
	function distance($fromLat, $fromLon, $toLat, $toLon) {
	$radius = 6378.1; // 3963.17 miles
	$dLat = deg2rad($toLat - $fromLat);
	$dLon = deg2rad($toLon - $fromLon);
	$tmp = cos(deg2rad(($fromLat + $toLat) / 2)) * $dLon;
	$distance = $radius * sqrt($dLat * $dLat + $tmp * $tmp);
	return round($distance, 1);
	}
