查找 OSX 和 Swift 中支持的图像类型

我有一个应用程序，它使用用户通过 NSOpenPanel 选择的图像来设置 SKSprite 的纹理。选择文件后，我调用：

let newTexture = SKTexture(image: NSImage(byReferencing: imageURL))
textureSpriteNode.run(SKAction.setTexture(newTexture))

问题是，如果用户选择 .raf 文件 (FujiFilm RAW)，则 NSImage(byReferencing:_) 返回空白图像而不是抛出错误。

我尝试使用

openPanel.allowedFileTypes = NSImage.imageTypes

过滤用户可以在 NSOpenPanel 中选择的图像，但列表包含 FujiFilm RAW，因此面板允许用户选择其中之一。尝试在 OSX 预览版中打开同一文件将导致出现不支持此类图像的警告。

有没有办法从 OSX 获取支持的图像类型的真实列表？

I have an app which sets the texture of a SKSprite with an image chosen by the user via a NSOpenPanel. Once a file's chosen, I call:

let newTexture = SKTexture(image: NSImage(byReferencing: imageURL))
textureSpriteNode.run(SKAction.setTexture(newTexture))

The problem is that if a user chooses a .raf file (FujiFilm RAW), the NSImage(byReferencing:_) returns a blank image instead of throwing an error.

I've tried filtering the images that can be selected by the user in an NSOpenPanel by using

openPanel.allowedFileTypes = NSImage.imageTypes

But the list includes FujiFilm RAW so the panel allows the user to select one. Trying to open the same file in OSX's Preview will cause an alert to appear that this type of image isn't supported.

Is there a way of getting a true list of the supported image types from OSX?
