Continuous Delivery for Mobile with fastlane [EPUB ebook] 
Automating mobile application development and deployment for iOS and Android

Competitive mobile apps depend strongly on the development team’s ability to deliver successful releases, consistently and often. Although continuous integration took a more mainstream priority among the development industry, companies are starting to realize the importance of continuity beyond integration and testing.
This book starts off with a brief introduction to fastlane—a robust command-line tool that enables i OS and Android developers to automate their releasing workflow.
The book then explores and guides you through all of its features and utilities; it provides the reader a comprehensive understanding of the tool and how to implement them. Themes include setting up and managing your certificates and provisioning and push notification profiles; automating the creation of apps and managing the app metadata on i Tunes Connect and the Apple Developer Portal; and building, distributing and publishing your apps to the App Store.
You will also learn how to automate the generation of localized screenshots and mesh your continuous delivery workflow into a continuous integration workflow for a more robust setup. By the end of the book, you will gain substantial knowledge on delivering bug free, developer-independent, and stable application release cycle.
