• Use Slack to communicate with Bitrise

3. Why do we need automation?
• Simplify work
fl
ow
• Save time and money
• No one wants to handle boring and repeated tasks
• Prevent human mistakes

6. Introduction to Rome
What is Rom? What does it help us?
• Cache engine for Carthage which support many cloud storage provider
includes S3 and GCS.
• You build your frameworks one and just download it to reuse latter.
• Easy to use and maintain
• Easy to write new plugin to support any new storage provider
• Can manage multiple version of Swift

7. Introduction to Rome
Why do we need Rome?
• Reduce the time to wait for building all the frameworks by Carthage
• Faster onboarding new members
• Share built frameworks across members’s PC and CI servers
• Save time
• Save a lot of money on CI servers
• Reduce the time to distribute new versions

17. Introduction to Bitrise
The CI service created for mobile teams
Why Bitrise?
- The
fi
rst CI created for mobile development in mind
- Supports many development tools includes Fastlane
- Customize ability is pretty strong
- Free accounts can run up to 30 mins each build

18. Introduction to Bitrise
The CI service created for mobile teams
What Bitrise can do? It can do everything you can on your PC
- Manage certi

cates & provisioning pro
fi
les for you too!
- Build the app using xcbuild directly or via Fastlane
- Cache pre-built frameworks
- Upload to builds to AppStore
- Send noti

- And many more…

19. Introduction to Bitrise
The CI service created for mobile teams
So why don’t we just use Bitrise?

20. Introduction to Bitrise
The CI service created for mobile teams
So why don’t we just use Bitrise?
Because all of the Bitrise features are not available on your local PC.

21. Bitrise Bot
Interact with Bitrise with a chat bot
- Bitrise has an API that allows you to trigger a new build
- What we can do:
- Create a Slack chat bot to handle mention messages
- Request messages from Slack are processed by a handler
deploys on a serverless service with a few lines of code
- Trigger requests will be sent from the handler function on your behalf
