Save countless hours of work with this one simple trick Cocoaheads Montréal - 9/11/2015 

A couple of weeks ago, my girlfriend was out for the night so... 

...I played with Fastlane while watching Netflix (Please don't judge me) 

Why? TL;DL: Because you could be doing something else 

Command line tools are usually... • Boring* • Hard to use (intuitively) • Hard to script (properly) • Hard to maintain (by the next one) Apple's are no exception (* Except Carthage, Carthage we like.) 

Let's build an app (litteraly) 

Building an app xcodebuild -project Rewatch.xcodeproj \ -scheme Rewatch \ -configuration QA \ CONFIGURATION_BUILD_DIR="$CWD/build" clean build • 7 actions (clean, build, archive...) • 39 options • Terrible error reporting (usually "error 65") 

Packaging the app into an IPA xcrun -sdk iphoneos \ PackageApplication "$CWD/build/Rewatch.app" \ -o "$CWD/build/Rewatch.ipa" • Huge perl script • (Don't laught, perl 6 was released last month) 

Pushing the app on the App Store from the command line • ¯\(ϑ)/¯ • Unofficial API • Reverse engineered by looking at Application Loader ? 

Writing a script to wrap all this • Usually end-up copy/pasted accross multiple projects... • ...or shared as a submodules or something similar • Suggested a relatively simple one in my book, around 100LOC (#humblebrag) 

You're not done yet! • Code Signing certificates • Provisioning profiles • Screenshots • Push Certificates • ... 

Introducing Fastlane 

Introducing Fastlane • Automatize all the things you need and then some • Define and run your deployment pipelines for different environments (debug, qa, production...) • Written in Ruby (by the guy on the left, Felix Krause) • Each part can be use as standalone tools • iOSDevWeekly frequent flyer 

Let's build an app (litteraly) 

Building the app with Fastlane gym (seriously) 

Gym will... • Automatically detect your workspace and pick the scheme (or ask you for the one to use) • Wrap the output in xcpretty 

But wait, there is more • Deliver will upload your app and metadata to the app store • Snapshot will take screenshots • FrameIt will resize screenshots into right devie frames • Pem will manage your push notification profiles • Cert & Sigh will magically fix your code signing issues • Produce will create th app on iTunes Connect • Scan will run tests 

Wrapping the Fastlane tools using Fastlane gem install fastlane fastlane init (Even better is adding Fastlane as a dependency in your Gemfile) source "https://rubygems.org" gem 'fastlane', '~> 1.36', '>= 1.36.4'% 

Fastfile platform :ios do before_all do carthage(platform: "iOS") end desc "Submit a new Beta Build to Apple TestFlight" lane :beta do # ... end end 

Fastfile desc "Submit a new Beta Build to Apple TestFlight" lane :beta do sigh gym(scheme: "Rewatch", use_legacy_build_api: true) pilot end 

Using a lane fastlane beta 

Mirego 

Mirego • We just released a group of app • 6 apps x 5 screenshots x 5 devices = 150 screenshots took manually 

Mirego • Uses a 1300 LOC bash script that does a lot • It also handles a lot of cases so big up to our CTO for writing and maintaining that 

We are definitely looking into Fastlane (and hiring) 

Rewatch 

Rewatch ! Fastlane • iOS application that suggests episode to, well, rewatch • Hoping to release a beta soon-ish, register on rewatchapp.com • rewatchapp.com is using "Boarding" • rewatchapp.com was online in one hour (design included) 

Bonus • Fastlane has a great community • This is a true story • Posted a tweet the night I was playing with Fastlane • I hid my phone under a pillow because of the 40+ notifications I got in the following hour
