1.0 to 2.0

TypeReference removal

The TypeReference type was removed in v2.0.0, since it was made unnecessary when using the GraphQL closure-based field API. Simply replace any TypeReference usage with the actual type:

// Before
let schema = try! Schema<HelloResolver, HelloContext> {
    Type(Object1.self) { }
    Type(Object2.self) {
        Field("object1", at: \.object1, as: TypeReference<Object1>.self)
    }
}

// After
let schema = try! Schema<HelloResolver, HelloContext> {
    Type(Object1.self) { }
    Type(Object2.self) {
        Field("object1", at: \.object1)
    }
}

Field/InputField as argument removal

Since TypeReference was removed, there is no longer a functional need for the as argument on Field and InputField types. To remove it, simply omit it and let the compiler determine the type from the signature of the at argument.

Types removal

The deprecated Types type has been removed. Instead define types individually using the Type initializers.

Reflection isEncodable

The deprecated Reflection.isEncodable(type: Any.Type) -> Bool function has been removed. Please re-implement in your package if this functionality is needed.
