 * [TestFlight](https://developer.apple.com/testflight/), part of App Store Connect, let you build your iOS app and invite internal or external users to test it
 * [Google Play](https://support.google.com/googleplay/android-developer/answer/3131213?hl=fr), which does the same job as TestFlight for Android apps

 ## Installing Fastlane
 
 First you need to install Fastlane on your Mac. Follow these steps:
 
 1. Install the latest Xcode command line tools:
 ```
-xcode-select --install

 ### Code signing
 
 Signing your app assures users that it is from a known source and the app hasn’t been modified since it was last signed. Before your app can integrate app services, be installed on a device, or be submitted to the App Store, it must be signed with a certificate issued by Apple.
