You ever notice that you're building super long guard statements, or have tons of guards in a row?
guard let id = player.id, let name = player.name, let status = player.status else {
throw "Player might be missing fields id, name, and/or status"
}Instead of that, just require those fields:
let (id, name, status) = try require(from: player, \.id, \.name, \.status)The require function creates those guards for you 🎉
