iOS，Swift:如何保存包含自定义对象的数组，以便加载以供重用？

class CustomObject: NSObject, NSCoding {
    var name: String
    
    init(name: String) {
        self.name = name
    }
    
    func encode(with coder: NSCoder) {
        coder.encode(name, forKey: "name")
    }
    
    required init?(coder: NSCoder) {
        name = coder.decodeObject(forKey: "name") as? String ?? ""
    }
}

let object1 = CustomObject(name: "Object 1")
let object2 = CustomObject(name: "Object 2")
let object3 = CustomObject(name: "Object 3")

let array = [object1, object2, object3]

let fileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first?.appendingPathComponent("data.archive")

do {
    let data = try NSKeyedArchiver.archivedData(withRootObject: array, requiringSecureCoding: false)
    try data.write(to: fileURL)
} catch {
    print("Failed to save data: \(error)")
}

var loadedArray: [CustomObject] = []

do {
    let loadedData = try Data(contentsOf: fileURL)
    if let array = try NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(loadedData) as? [CustomObject] {
        loadedArray = array
    }
} catch {
    print("Failed to load data: \(error)")
}
