Swift 属性左侧预期编号列表

Question

我正在使用下面的代码创建警报样式的规则列表 UIAlertController

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = NSTextAlignment.Left
let messageText = NSMutableAttributedString(
    string: "1. Do not bully or target other users.\n2. Do not post others' private information.\n3. Do not post useless or offensive content.\n4. Do not post others' copyrighted content.\n5. Downvote and Flag posts which violate these rules.\n6. If you violate these rules, your account may be suspended and/or your content removed.",
    attributes: [
        NSParagraphStyleAttributeName: paragraphStyle,
        NSFontAttributeName : UIFont(name: "Lato-Regular", size: 13.0)!,
        NSForegroundColorAttributeName : colorAccentWords
    ]
)

它给我如下所示的警报视图：

我想要的是使编号列表按预期左对齐，以便每一行的溢出文本左对齐。我怎样才能做到这一点？
