Did this end up happening? I’m still finding that I have to run the following command from inside my workflows to use Swift Package Manager:

for ip in $(dig @8.8.8.8 github.com +short); do ssh-keyscan github.com,$ip; ssh-keyscan $ip; done 2>/dev/null >> ~/.ssh/known_hosts

Hey @tonyarnold. Are you able to run Swift package tests with private dependencies? If so can you please share your approach since I can’t make it work for some reason GitHub runner do not use the package’s local .ssh folder and always fails to fetch dependencies. There is a related topic. Thanks!

I am able to check out private Swift packages:

- name: "Set up SSH agent"
  uses: webfactory/ssh-agent@v0.1.1
  with:
    ssh-private-key: ${{ secrets.CI_SSH_PRIVATE_KEY }}

name: "Add GitHub to the SSH known hosts file"

run: |

for ip in $(dig @8.8.8.8 github.com +short); do 

ssh-keyscan github.com,$ip; 

ssh-keyscan $ip; 

done 2>/dev/null >> ~/.ssh/known_hosts

There is one other change you need to make if you’re using Xcode directly, rather than Swift Package Manager, and that is to pass the -usePackageSupportBuiltinSCM flag to xcodebuild.

Once you’ve done this, you should be fine!

@tonyarnold I just want to thank you immensely.

Finding your post, and your comment in regards to the -usePackageSupportBuiltinSCM flag for xcodebuild finally resolved a huge headache with GitHub Actions.

@tonyarnold I’m using fastlane, do you know how to pass -usePackageSupportBuiltinSCM to build_app?

Currently, I have tried and failed 😃
