我写了下面的代码。当我尝试调用 self.init 时，我得到的错误出现在我的便利初始化程序的末尾。我的逻辑或语法有什么问题？或者我将如何调试这个？Xcode 给出的错误是“不能使用类型的参数列表调用”。
感谢您对此的任何帮助
import Foundation

class Item: NSObject {
var name: String
var valueInDollars: Int
var serialNumber: String?
let dateCreated: NSDate
var stolen: Bool?
init(name: String, valueInDollars: Int, serialNumber: String?, dateCreated: NSDate, stolen: Bool?) {
self.name = name
self.valueInDollars = valueInDollars
self.serialNumber = serialNumber
self.dateCreated = NSDate()
self.stolen = stolen
//below why did I have to call super.init for this custom class that inherits from NSObject? Doesn't it automatically get called anyway once the custom object is initialized since it inherits from NSObject? It just seems like more work on my behalf which isn't fair. it should do it automatically. Why wouldn't it do it automatically if it inherits from NSObject?
super.init()

let adjectives = ["Fluffy", "Rusty", "Shiny"]
let nouns = ["MacBook Pro", "Red Tribe Bike", "Vegan Pizzas"]
//take a variable that's random; the highest value for this random number will be the number of ojbects in the adjectives array
var idx = arc4random_uniform(UInt32(adjectives.count))
//now use this random variable and let it be the index of the adjectives array...so basically it'll be a random object from the adjectives array
let randomAdjective = adjectives[Int(idx)]
//AWESOME!! Now that the random adjective is stored in the randomAdjective constant, let's re-use the idx variable...Ayyyyeeeee re-use!
//we'll re-use it by doing the same process or close to the same process for nouns
