Require

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 🎉

You can pass up to 10 KeyPaths.

Installation

• Add the Swift package

or

• Copy Require.swift to your project.
