Thank you for report.
swiftgen require libxml2. see SwiftGen README

SwiftGen's README said

Installation
To install SwiftGen via Mint, simply use:
$ brew install libxml2
$ mint install SwiftGen/SwiftGen

After installed libxml2 by manually, the SwiftGen build will succeed.

@roana0229 thank you!

I think it is good to add it to ios-base/README.md!
