Instead of

let path = dataFilePath()  
if let data = try? Data(contentsOf: path) {  
let unarchiver = NSKeyedUnarchiver(forReadingWith: data)  
items = unarchiver.decodeObject(forKey: “ChecklistItems”)  
unarchiver.finishDecoding()  
}

why not just to use NSKeyedUnarchiver.unarchiveObjectWithFile(some\_path) as? [ChecklistItem] in loading and NSKeyedArchiver.archiveRootObject(items, toFile: some\_path) in saving accordingly?

There’s often more than one way to do something. 😄
