Visual instructions how to enable Google Maps on IOS using react-native-maps

UPDATE: Following instructions are now a year old. I have recently managed to upgrade react-native-maps from 0.17 to the latest version 0.21 with react-native 0.51 - if you want to follow my instruction scroll down to the end this doc! Hope that will work for you too!

This is for my personal use, things might not be correctly explained here. For the official docs please check https://github.com/airbnb/react-native-maps

Steps from scratch:

1.react-native init GoogleMapPlayground

Note

Apple will reject apps that are using private url schemes (Ugh, Apple....) if they are pretty much obvius. Some apps are rejected and others are not, so, be aware of this issue before implementing any of those URL's in your app as a feature.

Updates

• [UPDATE 4] iOS 10 update: apparently settings now can be reached using App-Pref instead of prefs
• [UPDATE 3] For now you just can use url schemes to open your apps's settings with Swift 3.0 (Xcode 8). I'll keep you informed when OS preferences can be reached
• [UPDATE 2] The openURL() method of UIApplication is now deprecated. You should use application(_:open:options:) instead
• [UPDATE 1] Not yet tested in iOS 10. It will fail because of policies changes in URL scheme handling.

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.
