swift - 无法打开文件，因为您没有查看它的权限错误

Question

我用 Google 搜索并浏览了 Stack Overflow，但似乎找不到解决方案。我有:

let fileURL = URL( string: "file:///Users/me/file.txt" )    
var rawDataString: String 
var errorString: String?

do {
    rawDataString = try String( contentsOf: fileURL!, encoding: String.Encoding.utf8 )
} catch let error as NSError {
    errorString = error.description
    print( errorString! )
    return
}

它出错了

Error Domain=NSCocoaErrorDomain Code=257 "The file “file.txt” couldn’t be opened because you don’t have permission to view it."

读取所有用户的权限:

$ ls -al file.txt
-rw-r--r--@ 1 me  staff  348306 Dec 13  2016 file.txt

欢迎提出任何想法。

任何遇到这个话题的人，@LeoDabus 都会告诉我在哪里关闭沙盒，这很有效:

他还稍微清理了我的代码:

let fileURL = URL( fileURLWithPath: "/Users/me/file.txt" )    
var rawDataString: String
var errorString: String?

do {
    rawDataString = try String( contentsOf: fileURL, encoding: .utf8 )
} catch let error as NSError {
    errorString = error.description
    rawDataString = ""
    return
}
