Goal

Make this project work for all Swift platforms.

Work plan

• [ ] Clone https://github.com/Alamofire/Alamofire
• [ ] Run the configure script. That is our basis to begin
• [ ] Get all tests to run locally across the whole matrix and document this
• [ ] Rip out CocoaPods and every other part we don't need
• [ ] Get all tests to run locally across the whole matrix and document this
• [ ] Rip out the Swift package feature except for the features we have in this project
• [ ] Get all tests to run locally across the whole matrix and document this
• [ ] Show diff of that working copy versus what is here
• [ ] Make decisions about any differences in our/their best practices, cite them, change to our best practices
• [ ] Get all tests to run locally across the whole matrix and document this
• [ ] Show diff of that working copy versus what is here
• [ ] Stash your work
• [ ] Somehow back our way into producing that working copy by updating our recipe
• [ ] Diff your working copy and update recipe until there the recipe materially produces that working copy
• [ ] Get all tests to run locally across the whole matrix and document this
• [ ] Publish the new recipe!
• [ ] Repeat this process every year
