15. JENKINS

16. ABOUT JENKINS
• Open Source
• Easy to install
• Best known CI solution

17. INSTALL JENKINS

18. ADD PLUGINS

19. ADD PLUGINS

20. CREATE A JOB
CREATE A JOB

21. CREATE A JOB
• Set up Github url and restrict where the job should be run if your
mac is a node of Jenkins.

22. CREATE A JOB WITH
PLUGINS

23. CREATE A JOB WITH A
SCRIPT
Build your project, run Unit Tests, compute code coverage, package
your app, deploy it etc…
$ pod install
$ xcodebuild -workspace Lima.xcworkspace -scheme "Lima"
-destination=build -configuration Debug_deploy -sdk
iphoneos7.0 ONLY_ACTIVE_ARCH=YES clean build archive
$ xcodebuild -exportArchive -exportFormat "IPA" archivePath "$NEW_ARCHIVE" -exportPath ./Lima.ipa exportProvisioningProfile "Lima Adhoc Distribution"
# And then upload to testflight via curl
Full script here: https://gist.github.com/rvirin/7796647

24. PLUGINS vs SCRIPTS
Most of the time, plugins are easier to
use. Sometimes we don’t have other
choices to use plugins
Examples :
• cocoapods plugin if podFile is not in
root folder
• run Unit tests with Xcode plugin

25. THAT’S IT, YOU CAN ENJOY
NOW…

26. AND ONE DAY, THE BUILD
FAIL !

27. WE NEED TO KNOW WHEN
BUILD FAILED
• Basic Alert : Email
• Growl Notification : Hudson-on-cocoa
• Or you can connect Jenkins to your real
life…

28. YOU’LL NEVER BROKE THE
BUILD AGAIN !

29. BOTS ON iOS

30. SETUP - REQUIREMENTS
• A mac (at least 10.9)
• OS X Server
• Xcode

31. SETUP
• Install OS X Server and Xcode on your
mac
• Activate Xcode as a service of your server
• Connect to remote repository
• Create your first bot

32. ERRORS DURING SETUP
• Error on getting source code -> no error,
big logs for nothing
• Add _teamserver public key to your Github
repository (deploy keys)

33. ERRORS DURING SETUP
• CodeSign error: code signing is required
for product type 'Application' in SDK 'iOS
7.0’  just trying to build the app !
•  Get your provisionning profile on the
mac server (Add your account to Xcode)

34. SETUP
• If you have to install your pods before
building your app :

# Same thing without a password
# %wheel
ALL=(ALL) NOPASSWD: ALL
%_teamsserver ALL=(ALL) NOPASSWD: ALL

38. COOL THINGS ON BOTS
• Bots Can be created and monitored from
Xcode.
• Integrate with Xcode
• UI and UX rocks.

39. BAD THINGS ON BOTS
• Lots of bugs
• Fetching pods before building app is painfull
• No 3rd party integration (Testflight, hockeyapp
etc…)
• Can’t Archive an app
• Need to create a specific scheme

40. SONAR
An open source platform for
Continuous Inspection of code
quality

41. SONARQUBE
•

42. SONARQUBE
• Issues with OCLint are powerfull
• Generate Documentation, Count lines of
code, analyze code duplication and run Unit
Tests !

44. CONCLUSION

45. IMPROVEMENTS
• « Thanks to Jenkins I’m able
to test the last version of our
app just by pressing a button,
it’s awesome ! » Alex Product
Guy at Lima

46. IMPROVEMENTS
• « Each day at 4pm, we get a
new build of our app, it’s really
efficient to reduce the amount
of bugs » Tester at Meetic

47. COST : 8 to 10 % of the project

48. THANKS !
