Xcode source editor extension install issues

[martin-slalom]

I've been trying, unsuccessfully, to install the application via brew as well as just manually downloading the SwiftFormat.for.Xcode.app.zip.

With the brew approach I get

$ brew install --cask swiftformat-for-xcode

To retry an incomplete download, remove the file above.

With manual "zip" approach

I've tried, updating/upgrading/cleaning brew all resulting in the same issue. I'm at a loss, anyone else having these issues?
