Xcode 8.0 和 swift 3.0 中的 ScriptingBridge 代码错误

Question

这是我在 Xcode 7.3.1 中使用的代码，运行良好：

    var selectedFiles = NSMutableArray(capacity:1)
    let  finder: AnyObject! = SBApplication(bundleIdentifier:"com.apple.finder")
    let finderObject = finder.selection as! SBObject
    let selection: AnyObject! = finderObject.get()
    let items = selection.arrayByApplyingSelector(Selector("URL"))

    let filteredfiles = (items as NSArray).pathsMatchingExtensions(["ai","pdf","ap","paf","pafsc"])
    for  item in filteredfiles {
        let url = NSURL(string:item ,relativeToURL:nil)
        selectedFiles.addObject(url!)
    }

这是针对 Xcode 8.0 更正的代码，但它不起作用：最后一行产生错误

错误 = 无法调用非函数类型“[Any]!”的值

    var selectedFiles = NSMutableArray(capacity:1)
    let  finder: AnyObject! = SBApplication(bundleIdentifier:"com.apple.finder")
    let finderObject = finder.selection as! SBObject
    if let selection = finderObject.get()  as AnyObject?{
        let items =  selection.array(#selector(getter: NSTextCheckingResult.url))
        let filteredfiles = (items as NSArray).pathsMatchingExtensions(["ai","pdf","ap","paf","pafsc"])
        for  item in filteredfiles {
          let url = NSURL(string:item ,relativeToURL:nil)
          selectedFiles.addObject(url!)
       }
    }

我试过很多办法，可惜找不到头绪。我想这是因为 Swift 3.0x API 发生了巨大变化.... 欢迎任何帮助！

这是一种略有不同的方法，使用几个本机 Swift 函数 Swift 3

var selectedFiles = [URL]()
let  finder : AnyObject = SBApplication(bundleIdentifier:"com.apple.finder")!
let finderObject = finder.selection as! SBObject
if let selection = finderObject.get() as? [SBObject] {
  selection.forEach { item in
      let url = URL(string: item.value(forKey:"URL") as! String)!
      selectedFiles.append(url)
    }

  let goodExtensions = ["ai","pdf","ap","paf","pafsc"]
  let filteredURLs = selectedFiles.filter({goodExtensions.contains([=10=].pathExtension)})
  print(filteredURLs)
}

PS：我强烈推荐使用AppleScriptObjC。使用起来非常简单。

PPS：valueForKey是有意使用的，因为确实需要KVC才能得到属性值。
