[Xcode] How CI/CD work

source

Recently I just integrate Codemagic to my Capstone Project and I found something interesting.

How they work ?

• First machine used by many people
• Second how machine used specific Certificate
• Third how machine embed specific Provisioning Profile
• Fourth Run xcodebuild with specific configuration

Previously I didnt notice how they work because we just use tools like Fastlane etc, and we just Run it locally. After I integrate Codemagic my curiosity arose. So I try to understand how they work correctly.

Codemagic

From image above we seeing that fist

• Machine is prepared by system
• Fetching app sources : Downloading app from github
• Setup signing code : This mean, machine downloading Certificate from backend
• Keychain Initialize : Create and Set Keychain (I need to learn more about this)
• Add Certificate to Keychain
• Setup Provisioning Profile to project
• Then Run Test (This is our script that we need to run)
• Build Debug (This is our script that we need to run)
• Publishing : Uploading artifact
• Cleaning

workflows:
  ios-project-debug:
    name: iOS debug
    environment:
      xcode: latest
      cocoapods: default
      vars:
        XCODE_PROJECT: "[PROJECT NAME].xcodeproj"
        XCODE_SCHEME: "[PROJECT SCHEME]"
      ios_signing:
        distribution_type: development
        bundle_identifier: [YOUR BUNDLE ID]
    scripts:
      - script: keychain initialize
      - script: keychain add-certificates
      - script: xcode-project use-profiles
      - name: Run tests
        script: |
          xcodebuild clean test \
          -project "$XCODE_PROJECT" \
          -scheme "$XCODE_SCHEME" \
          -sdk iphonesimulator \
          -destination 'platform=iOS Simulator,name=iPhone 14 Pro Max,OS=16.1'
      - name: Build debug app
        script: |
          xcodebuild build -project "$XCODE_PROJECT" \
          -scheme "$XCODE_SCHEME" \
          CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO CODE_SIGNING_ALLOWED=NO
    artifacts:
      - $HOME/Library/Developer/Xcode/DerivedData/**/Build/**/*.app
    publishing:
      email:
        recipients:
          - xxx@gmail.com [YOUR EMAIL]

Oke what if we want replicate that command in local our machine, so we need to register CODE_SIGN_IDENTITY and PROVISIONING_PROFILE every xcodebuild command (Let’s assume the certificate and provisioning profile has been installed).

First we need to know our installed CODE_SIGN_IDENTITY, so how we know ? Use this command in terminal

security find-identity -v -p codesigning

1) xxxxxxxxxxxxxxxxxxxxxxxxxxx "Apple Development: YOUR NAME (YOUR TEAM)"

Next we need to know all Provisioning Profile installed

cd ~/Library/MobileDevice/Provisioning\ Profiles ls

xxxxxxxxxxxxxxxxxxxxxxxxxxx.mobileprovision xxxxxxxxxxxxxxxxxxxxxxxxxxx.mobileprovision
xxxxxxxxxxxxxxxxxxxxxxxxxxx.mobileprovision

After we got all what we need we can start Run command script, for example I want Run Unit Test.

xcodebuild clean test -project [PROJECT NAME].xcodeproj -scheme [SCHEME NAME] -sdk iphonesimulator -destination “platform=iOS Simulator,name=iPhone 14 Pro,OS=16.2” PROVISIONING_PROFILE=“xxxxxxxxxxxxxxxxxxxxxxxxxxx” CODE_SIGN_IDENTITY="Apple Development"

Done, just Enter and let see !!
