Improving times for both iOS build and CI for a React Native app

Intro

Hello there.

So, if you are here you probably saw my previous tweet where I asked for tips & tricks on improving the timing on an iOS/React Native app build time.

What will follow was how I mixed those suggestions + some good old GoogleSearch-fu + me deep diving on this for ~2 days.

	#!/usr/bin/python

	'''
	Python implementation of passcode hashing algorithm used on the Samsung Galaxy S4 GT-I9505 4.2.2
	Correct PIN for hash and salt below is 1234.

	Get 40-character hash value in ascii hex format from file /data/system/password.key on the phone

	Get salt in signed numeric format by doing sqlite3 query SELECT value FROM locksettings WHERE name = 'lockscreen.password_salt' on /data/system/locksettings.db

	// In app.js or main.js or whatever:
	// var myApp = angular.module('askchisne', ['ngSanitize', 'ngAnimate', 'ui.bootstrap', 'ui.bootstrap.tpls']);

	// This filter makes the assumption that the input will be in decimal form (i.e. 17% is 0.17).
	myApp.filter('percentage', ['$filter', function ($filter) {
	return function (input, decimals) {
	return $filter('number')(input * 100, decimals) + '%';
	};
	}]);
