你能检查一个类型(不是一个实例)是否是另一个类型的子类吗？

class Vehicle{}

class Car : Vehicle {}

class Honda : Car {}

class TypeManager {

    var managedTypes:[Any.Type]?

    func findFirst(_ type:Any.Type) -> Any.Type? {
        return managedTypes.first{ t in t is type.Type } // <-- Doesn't like 'type'
    }
}

var typeManager = TypeManager()
typeManager.managedTypes = [
    String.self,
    Int.self,
    Honda.self
]

let firstCarType = typeManager.findFirst(Car.Type)
