struct Fields {
  var userFields: Set<User.Fields>?
  var tweetFields: Set<Tweet.Fields>?
}

protocol Fetcher {
  // Is there a way to do something like this, where I can specify that the `Fields`
  // struct must contain only these member types?
  func getTweet(fields: Fields<Tweet.Fields, User.Fields>? = nil) async -> Tweet
  func getUser(fields: Fields<User.Fields>? = nil) async -> User

struct User: Codable, Identifiable {
  typealias ID = String
  let id: ID
  let name: String
  let username: String

  // Assume that items can be optionally set in getUser
  var items: UserItems?
}

I’m trying to decode two slightly different JSON API responses to the same Codable type, Account. Mapping userResponse.json’s uid to id is trivial, but extracting the nested user is stumping me.

Any suggestions would be greatly appreciated!

git clone and cd function

A simple little alias function that lets you clone and cd into a GitHub repo in one command.

Installation

Add to your zsh or bash config (usually ~/.bash_profile or ~/.zshrc) and open a new terminal to be able to use the function.

Usage

gcd [github_repo_owner/repo_name]

// I learned in this post (https://overreacted.io/react-as-a-ui-runtime/)
// that arguments passed to a function run before the function itself:
/**
 * // This runs second
 * outerFunction(
 *  // This runs first
 *  innerFunction()
 * )
 */
// This makes sense. But I wondered what it looked like in practice.

Grid Breakpoint API Dilemma

We want a responsive grid API that allows for an arbitrary number of breakpoints to be defined, but there's an issue with how the breakpoint extremities are treated. Given the following API:

<Grid breakpoints={[300, 600, 900]}>
  <Column width={[1, 1/2, 1/4]} />
</Grid>
