向CALayer添加文本:drawInRect无法正常工作

let textAttributes = [
    NSAttributedString.Key.font: UIFont.systemFont(ofSize: 14),
    NSAttributedString.Key.foregroundColor: UIColor.black
]

override func draw(in ctx: CGContext) {
    super.draw(in: ctx)
    
    let text = "Hello, World!"
    let textAttributes = [
        NSAttributedString.Key.font: UIFont.systemFont(ofSize: 14),
        NSAttributedString.Key.foregroundColor: UIColor.black
    ]
    
    let size = text.size(withAttributes: textAttributes)
    let rect = CGRect(x: 10, y: 10, width: size.width, height: size.height)
    
    text.draw(in: rect, withAttributes: textAttributes)
}
