I want to simulate downloading an image file (png) and storing it in SwiftUI. How do I simply copy a file from finder into my xcode project so I can reference it for a test/demo? I want to get the raw bytes from it.

我想模拟下载图像文件(PNG)并将其存储在SwiftUI中。我如何简单地将文件从finder复制到我的Xcode项目中，以便我可以引用它进行测试/演示？我想要从中获取原始字节。

I've looked and it seems like you can copy things files into assets, but I'm not sure that will represent what I eventually want to do, which is download them and store them.

我已经看过了，似乎可以将文件复制到资产中，但我不确定这是否代表我最终想要做的事情，即下载并存储它们。

Is there any way to drag an image file into an xcode project?

有没有办法将图像文件拖到Xcode项目中？

Just as @stackish commented I clicked and dragged the png file into the project. There was a dialog message and I accepted the default settings.

就像@stackish评论的那样，我点击并将PNG文件拖到项目中。出现一条对话框消息，我接受了默认设置。

guard let path = Bundle.main.path(forResource: "myimage", ofType: "png") else {
    print("Could not open file")
    return
}

A pretty comfortable way is the Asset Catalog

一种非常舒适的方式是资产目录

1. Select the Asset Catalog in the Project Navigator.

   
   



2. Click on the + button at the bottom of the asset list and choose Image Set.

   
   



3. Use a meaningful name for the asset for example Placeholder

   
   



4. Drag the image from the Finder into the 1x, 2x, or 3x square according to the resolution.

   
   



5. In the code use

   
   

   Image("Placeholder")
   

   
   

But why not still simpler with SF Symbols

但为什么不更简单地使用SF符号呢

Image(systemName: "photo")
    .font(.largeTitle)
