Guard isn’t really the right answer for this, I’d try something like this
(where unwrapOrThrow is the obvious generic function you can define yourself):
init?(data: [String: Any]) {
do {
self.someProperty = try unwrapOrThrow(data["some_key”])
self.anotherProperty = try unwrapOrThrow(data["another_key”])
} catch {
return nil
}
}
