如何在SwiftUI中更改NSTextView中的 Select colored颜色

如果你的意思是NSTextView，这里有一个可能的方法:

struct SelectableTextView: NSViewRepresentable {
    let text: String
    let font: NSFont?
    
    init(text: String, font: NSFont? = nil) {
        self.text = text
        self.font = font
    }
    
    func makeNSView(context: Context) -> NSTextView {
        let textView = NSTextView(frame: .zero)
        textView.isEditable = false
        textView.isSelectable = true
        textView.backgroundColor = .clear
        textView.font = font ?? NSFont.systemFont(ofSize: NSFont.systemFontSize)
        textView.string = text
        
        textView.selectedTextAttributes = [
            NSAttributedString.Key.foregroundColor : NSColor.systemGreen, // Change the text color
            NSAttributedString.Key.backgroundColor: NSColor.systemRed// Change the background color
        ]
        return textView
    }
    
    func updateNSView(_ nsView: NSTextView, context: Context) {
        nsView.string = text
        nsView.font = font ?? NSFont.systemFont(ofSize: NSFont.systemFontSize)
    }
}
