App deployment can be frustrating and time consuming. At LookLive, we have optimized this process using a tool called Fastlane. In this talk, I will demonstrate how we did it and you'll learn how you can set up Fastlane for your own projects.

Developing in the Fastlane
How LookLive uses Fastlane to automate and speed up the
app deployment process

2. www.looklive.com@donnywals
A typical deploy day..
Finalize code
Hurry to write some tests
Run tests
Upload to Crashlytics
Update release notes
Upload to iTunes Connect
Wait…
Update (localized) app info
Update (localized) screenshots
Submit build
Wait for review…
Archive build
Update build number
Update release notes

3. www.looklive.com@donnywals
That’s a lot of steps
And I actually forgot a couple..

Fastlane to the rescue
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 and Gradle.

Feature-packed
• A range of built in actions (incrementing build
numbers, pushing to git, tagging your repo,
crashlytics and more)
• A lot of integrated tools (sigh, gym, scan, pilot and
more)

The develop lane
increment_build_number
commit_version_bump
sigh(development: true)
scan(scheme: 'LookLive')
gym(scheme: "LookLive")
crashlytics(
crashlytics_path: ‘:path_to_crashlytics:’,

Because I always forget
Download certificates,
test (UI and unit) and build
Send beta to Crashlytics
for dev testing
Clean up, tag the repo
and push to git

Mind blowing awesomeness.
[sound of mind blowing up]

23. www.looklive.com@donnywals
The beta lane
sigh
scan(scheme: 'LookLive')

The deliver lane
deliver(
force: true,

)
Uploads all the things

25. www.looklive.com@donnywals
Two more things…
error do |lane, exception|
clean_build_artifacts
end
and
before_all do
ensure_git_status_clean
end

Time saved:
± 15 minutes for a beta
± 30 minutes for metadata changes
± 4 hours for screenshot updates

27. www.looklive.com@donnywals
Nice, but we can do more

28. www.looklive.com@donnywals
Next level
• Use snapshot to automate localised screenshots
• Run fastlane on a Jenkins slave
• Automate submitting for review

29. www.looklive.com@donnywals
And that’s how we brought
deployment to the Fastlane
