Swift 3 - 如何投射真实结果<Object>到泛型 [T]

Question

I have the following Realm function to fetch all elements from the table in my Swift 3 app.

//Find all elements in the database
func findAll() -> [T] {
   return getRealm().objects(T.self as! Object.Type)
}

How do I cast Result<Object> from Realm to [T] in the return?

Answer 1

func findAll<T: Object>() -> [T] {
  return getRealm().objects(T.self).map { $0 }
}

Answer 2

func findAll<T: Object>(type: T.Type) -> [T] {
    return getRealm().objects(type).map { $0 }
}
