Fluent 2.0 Alpha 4

New:

• Storable base to allow easier protocol extensions
• IdKey conveniences

Changed:

• Fluent now enforces reference types, use final class in place of struct on existing conformers.
• Swift 3.1

Warning:

• id and exists are now implemented natively by Fluent, this means a few changes are required. All instances of var id: Node? and var exists on models MUST be deleted for Fluent to function properly.
• if you are setting id manually in initializers, it MUST happen AFTER the initialization to function properly. In practice, this means usually put id = ... at the BOTTOM of your initializer if you need to do it.

let name: String

init(node: Node, in context: Context) throws {
    id = try node.extract("id") // will fail
    name = try node.extract("name")
}

=>

let name: String

init(node: Node, in context: Context) throws {
    name = try node.extract("name")
    // called after initialization proper
    id = try node.extract("id")
}
