what’s fastlane?

fastlane lets you define and run your deployment pipelines for different environments

It helps you unify your app’s release process and automate the whole process

fastlane connects all fastlane tools and third party tools, like CocoaPods

lanes

lanes are typically deployment pipelines

and the recipe is yours

tools

single command.

every device

quickly put your screenshots into the right device frames

automatically generate and renew your push notification profiles

because you would rather spend your time building stuff than

fighting provisioning

create new iOS apps on iTunes Connect and Developer Portal using

the command line

automatically create and maintain iOS code signing certificates

the easiest way to run tests of your iOS and Mac app

building your iOS app has never been easier

easily sync your certificates and profiles across your team using

Git

the best way to manage your TestFlight testers and builds from

.gitignoremake sure you don’t include fastlane

generated files in your repo

gitignore.iopro tip: use it in commandline

frameityou need to download the templates from apple’s website. tool will point you to right place for the first time setup.

app iconsYour app icons needs to be configured

properly to upload to App Store. use utilities like makeappicon.com to

generate required images size.

CI Environment Variables

It’s not a good idea to embed the secret keys and files within the code/repo.

Use environment variables, settings and integration features of CI Server to secure

your data

use private reposthere are several bots pulling out keys and

content from the public github repo. don’t put your projects at risk.

🔐

auto build number increment

to automate the build number increment, you have to set the version in the project’s

build settings
