Swift와 Objective C 배열 사이의 변환

Question

내 응용 프로그램에는 Objective C로 작성된 일부 기본 레거시 코드가 있지만 겹치는 메서드는 Swift로 작성되었습니다.

이제 스위프트 코드는 스위프트 배열 [Int]을 사용하지만 목표 C 방법은 NSArray 및 NSMutableArray이 필요합니다.

다른 배열 유형을 변환/변환하는 방법은 무엇입니까?

스위프트 코드 :

/* The remaining orders are finally stored as [Int] */ 
static var remainingOrders:[Int]! = [Int]() 

/* Handles the orders loaded event */ 
@objc static func ordersLoaded(notification:Notification) { 
    let userInfo:Dictionary = notification.userInfo as! Dictionary<String, Any> 
    let orders:NSArray = userInfo["orders"] as! NSArray // orders is of type NSArray 
    let remainingOrders:NSMutableArray = orderUtils.filterRemainingOrders(fromOrders: orders.mutableCopy() as! NSMutableArray); // but it needs to be passed as NSMutableArray 
    self.remainingOrders = remainingOrders as! [Int]; // the NSMutableArray needs to be stored as [Int] 
    downloadService.download([Any](self.remainingOrders)); // then remaining orders need to be passed as NSArray 
} 

목표 C 메소드 서명은 (수정할 수 없습니다) : (self.remainingOrders를 캐스팅

/* The remaining orders are finally stored as [Int] */ 
static var remainingOrders:[Int]! = [Int]() 

/* Handles the orders loaded event */ 
@objc static func ordersLoaded(notification:Notification) { 
    let userInfo:Dictionary = notification.userInfo as! Dictionary<String, Any> 
    let orders:NSArray = userInfo["orders"] as! NSArray // orders is of type NSArray 
    let remainingOrders:NSMutableArray = orderUtils.filterRemainingOrders(fromOrders: orders.mutableCopy() as! NSMutableArray); // but it needs to be passed as NSMutableArray 
    self.remainingOrders = remainingOrders as NSArray as! [Int]; // the NSMutableArray needs to be stored as [Int] 
    downloadService.download(self.remainingOrders); // then remaining orders need to be passed as NSArray 
}

내 솔루션입니다 NSArray로).
