iOS App Distribution Process 3

Practices of Continuous Integration>  Maintain a code repository>  Automate the build>  Make the build self-testing>  Everyone commits to the baseline every day>  Every commit (to baseline) should be built>  Keep the build fast>  Test in a clone of the production environment>  Make it easy to get the latest deliverables>  Everyone can see the results of the latest build>  Automate deployment 4

overview>  Open source continuous integration service provider>  Runs in servlet container such as Apache Tomcat>  iOS Projects MUST be build on Mac>  Jenkins instances as slaves 5

Configuring Jenkins Mac Slave 6

Create New Job>  Properties that must be set 7

Custom build system>  Implemented in Ruby>  Rake wrapper around xcodebuild –  Rakefile –  Several Ruby scripts –  Included in our xCode project templates 8

Rakefilexcode_project :"___PROJECTNAME___" do! # The artifact_id is a alias for the main Xcode target! artifact_id "___ARTIFACT_ID___”! project_id "___PROJECT_ID___"! group_id "___GROUP_ID___"! svn "___SVN___"!! release_destination "http://buildfs.group.nca/dav/projects/___PROJECTNAME___/release/"! snapshot_destination "http://buildfs.group.nca/dav/projects/___PROJECTNAME___/snapshots/"!! itunes_artwork "src/main/resources/iTunesArtwork”!! adhoc_package "NetceteraAdhoc" do! identity "iPhone Distribution: Netcetera AG"! # by default the provisioning profile used will be src/packaging/ADHOC_PACKAGE_NAME.mobileprovision! # you can override by using! # provisioning_profile "path to provisioning profile"! end!end! 9

Rake tasksagavrilo-2:agavrilo$ rake –tasks!rake build # Invokes xcode build to compile the project!rake ci # Invoked by the CI system!rake clean # Cleans the project!rake package # Creates the packages!rake release # Performs a release!rake release:rollback # [TBD]!rake report # Reports to techISR.!rake symbolicate # Symbolicates the crash report provided under the REPORT variable.!rake test # Invokes The tests!rake uitest # Run Cucumber features!!!task "ci" => "deliver-snapshot”!task "deliver-snapshot" => "package” !task "package" => ["appstore-package", "adhoc-packages"]!!! 10

Test execution>  rake test!>  GHUnit as testing framework>  Jenkins can run GHUnit tests –  http://gabriel.github.com/gh-unit/docs/appledoc_include/guide_ci.html!>  UnitTest target should Run Script>  Tests are executed on Simulator>  JUnit test result report is created (XML file)>  Reports to internal reporting tool 11

Packaging>  rake package!>  ‘Release’ configuration must exist in project scheme!>  Creates app store package>  .dSYM file is stored>  Creates adhoc packages by resigning the app store packages –  Decreases the build time –  App store and adhoc application are both identical! 12

Deployment>  rake delivery!>  Deploys all artifacts to snapshot_destination! –  All provisioning profiles –  App store build –  .dSYM package –  *.ipa packages>  Ready to be fetched for testing or submission in iTunes Connect 13

Debugging: Symbolicate crash >  rake symbolicate REPORT=path_to_report! –  REPORT can be a path to directory >  Extract the uuid from the crash reportlines = File.readlines(report).map {|line| line.tr("rn", )}!!line = lines[lines.index("Binary Images:") + 1]!!line.match(/armv[67] +<[0-9a-z]+>/)[0].split( ).map {|entry| entry.tr("<>", )}! >  find the appropriate (matching) build on the DAV server "No snapshot can be found that matches uuid: #{uuid}, for architecture: #{arch}”! >  download it >  unpack it >  symbolicate it 14

Conclusion>  Benefits –  Not dependent on xCode version –  Control of the build process –  Control of the project state –  Applications are always ready to be tested –  Debugging –  Scalable and configurable build system • build of workspace • Installation of pods>  Improvements –  Installation of certificates in keychain –  Check for code duplicates –  Check style 15
