Question

如何將這個經典的 Swift 線更新為更新的 Swift（與 Xcode 12 和 Z1BDF605991920DB1EB1CBD148 兼容）正確？

var sceneData = NSData(bytesNoCopy: path, length: .DataReadingMappedIfSafe, freeWhenDone: true)

提前致謝！

我跋涉並找到了一種方法，所以回答了這個問題：

extension SKNode {
            class func unarchiveFromFile(_ file : String) -> SKNode? {
                if let url = Bundle.main.url(forResource: file, withExtension: "sks") {
                    do {
                        var sceneData = try NSData(contentsOfFile: url.absoluteString, options: NSData.ReadingOptions.mappedIfSafe)
                        var archiver = NSKeyedUnarchiver(forReadingWith: sceneData as Data)

                        archiver.setClass(self.classForKeyedUnarchiver(), forClassName: "SKScene")
                        let scene = archiver.decodeObject(forKey: NSKeyedArchiveRootObjectKey) as! GameScene
                        archiver.finishDecoding()
                        return scene
                    } catch {
                        return nil
                    }
                } else {
                    return nil
                }
            }
}
