Xcode 11 - "Couldn't communicate with a helper application." when attempting to add Swift Package

I am having problems when I attempt to add a new Swift Package to my project.

On Xcode 11.3.1 I receive a "Couldn't communicate with a helper application." error message.

PS with Xcode 11.4 the error message has changed to "Communication with the service was interrupted."

Solution

  • I've finally worked out what this was. I had something in my ~/.gitconfig file which Xcode obviously did't like.

    I worked this out by removing the ~/.gitconfig and then retrying (and it worked). Then I tried removing parts of the ~/.gitconfig contents bit by bit.

    Evntually I idenitified that this was the section causing the issue. 

    [includeIf "gitdir:~/some/path/"]
    path = "~/some/path/.gitconfig_include"

    This section works in other contexts. No idea why it causes Xcode to barf.
