swift - 沙盒扩展创建失败 : client lacks entitlements? 路径:

Question

我正在尝试实现查看屏幕截图。当我运行我的代码时，我遇到了一些错误并且捕获失败。

这是我的代码:

func saveSelfAsImage() {
    self.lockFocus()
    let image = NSImage(data: self.dataWithPDF(inside: self.bounds))
    self.unlockFocus()
    let imageData = image!.tiffRepresentation

    let fileManager = FileManager.default
    let path = "/Users/wudi/Documents/image.png"
    fileManager.createFile(atPath: path, contents: imageData, attributes: nil)

    let fileURL = URL(fileURLWithPath: path)
    NSWorkspace.shared.activateFileViewerSelecting([fileURL])
}

错误日志如下:

日志显示客户端缺少授权。但是如何获得权利呢？我在日志中用关键字搜索错误，但没有找到任何有用的东西。有没有人遇到过类似的问题？

问题解决了。感谢 EI Tomato 和 Willeke 的帮助。

关闭 App Sandbox 或增加文件访问权限可以解决此问题。
