Swift读取Text文本文件

func getTextFileStr(filename:String!) -> String! {
        if let path = Bundle.main.path(forResource: filename, ofType: "txt") {
            do {
                let data = try String(contentsOfFile: path, encoding: .utf8)
                return data
            } catch {
                print(error)
            }
        }
        return ""
    }

方法有些简单，就是这么简单。
