Extremely low battery usage hike tracker for iOS

A simple text-based tracking app for iOS to bring on hikes and bikes that gives you all the info you need and nothing more.

Features

• your current lat, lon
• distance along gpx track
• off trail warning and visual guidance back to trail
• current elevation
• distance to goal
• elevation gain and loss to goal
• sunrise and sunet times
• switch between metric and imperial units
• change goal distance

Usage

You need to prepare you gpx data into a specific format for this app and then replace the contents bruce_all.txt with your precomputed data. The file format is as follows:

tracks = [[<LAT>, <LON>, <ELEVATION>, <DISTANCE_FROM_START>], [...], ...];
poi = [[<LAT>, <LON>, <ELEVATION>, <DISTANCE_FROM_START>, <HEADER_TEXT>, <MAIN_TEXT>, <MORE_TEXT>], [...], ...];

So essentially there are two 2-dimensional lists (tracks and poi) containing data which will be parsed and each list is separated by a ;

The type for the elements in these lists is as follows (extracted from the code):

var tracks: [[Double]] = [];
var poi: [(Double, Double, Double, Double, String, String, String)] = [];

Please refer to the bruce_all.txt file already present in the project for a real example.
