github Action erorr: xcodebuild: error: '.xcproject' does not exist

Here is the workflow execution log:

Run xcodebuild clean build -project ExGithubAction/ExGithubAction.xcproject -scheme ExGithubAction
Command line invocation:
    /Applications/Xcode_13.2.1.app/Contents/Developer/usr/bin/xcodebuild clean build -project ExGithubAction.xcproject -scheme ExGithubAction

User defaults from command line:
    IDEPackageSupportUseBuiltinSCM = YES

xcodebuild: error: 'ExGithubAction.xcproject' does not exist.
Error: Process completed with exit code 66.

How can I get past the error 'ExGithubAction.xcproject' does not exist?

Solution

First, as a step (after the uses: actions/checkout@v3) to do a ls and confirm that ExGithubAction.xcproject is indeed checked out.

Second, as in this thread, specify the full path:

xcodebuild \
    -workspace MyProject.xcworkspace \
    -scheme MyProject \
    -sdk iphonesimulator8.1 \
    -configuration Release \
    clean build \
    OBJROOT=$(PWD)/build \
    SYMROOT=$(PWD)/build

(adapt it and remove the options you do not need)

If you have a obfuscate_project script, you have would need to provide proper values to variables corresponding to your project in the first section of the script and commit those changes.

# General build options
# WORKSPACE=YourWorkspace.xcworkspace
PROJECT=YourProject.xcodeproj
SCHEME=YourScheme
CONFIGURATION=Release
SDK=7.1
