# executable. The build VM is expected to have the appropriate environment to
# be able to build the app and the upload VM - to upload the app. Both must be
# reachable via SSH without a password via the SSH key located in
# ~/.ssh/ios-vm-key.

# non-whitespaced `~/build`, built there and the resulting `MullvadVPN.ipa` is
# copied back.
