This document discusses how continuous delivery can be implemented for iOS projects using the tool fastlane. Fastlane can automate and simplify an iOS project's release process by integrating and connecting various build tools and scripts. It describes how fastlane can handle tasks like building, testing, generating screenshots, managing provisioning profiles and certificates, and releasing to app stores. The document advocates using fastlane to define custom lanes for different release workflows and provides examples of how it can automate individual steps in the iOS release process.

1. Continuos Delivery for
iOS Projects

3. With a commit.
How does continuos delivery begin?

4. Continuos Delivery
How does that translate for your iOS project?
• “We cannot release now - our lead developer is on vacation.”
• “We’ll have to wait for marketing to update the screenshots”
• “Sorry, I forgot to add your device to the provisioning profile.”
• “We’ll release this fix with the next build… next year”

5. Your usual release day

6. If it's complicated… simplify
• Your CI server usually had to contain a lot of tools:
• xctool
• PMD
• Slather
• oclint
• gcovr
• Hockey app, Crashlitycs, Testflight plugins
• Cocoapods or Carthage installed
• Keychain plugin
• Slack or HipChat plugin

7. If it's complicated… simplify
• … and a lot of scripts:
xcodebuild clean archive -archivePath build/MyApp
-scheme MyApp
xcodebuild -exportArchive
-exportFormat ipa
-archivePath "build/MyApp.xcarchive"
-exportPath "build/MyApp.ipa"
-exportProvisioningProfile
"ProvisioningProfileName"
