NSTextView CoreText 注释：客户端请求的名称
NSTextView CoreText note: Client requested name
在 NSTextView 上将字体设置为 .monospacedSystemFont Xcode 时显示有关无效字体的警告。示例：
CoreText note: Client requested name ".SFNSMono-Bold", it will get Times-Roman rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[NSFont systemFontOfSize:]
为NSTextView.typingAttributes设置相同的字体，例如：
let textView = NSTextView()
textView.typingAttributes[.font] = NSFont.monospacedSystemFont(ofSize: NSFont.systemFontSize, weight: .regular)
textView.font = .monospacedSystemFont(ofSize: NSFont.systemFontSize, weight: .regular)
