UIDatePicker 作为带秒的倒数计时器 (Swift)

Question

So, apple updated the timer app in IOS 11, and one of the most useful things they've done is add a seconds column in the countdown timer, like this: countdown timer

I am building an app for personal use and need to use the timer, but for intervals smaller than a minute, but on xcode I can't use the same date picker that Apple used. Is there a way to build one or to make the UIDatePicker look like that?

Note: I don't understand Objective-C

您正在寻找UIPickerView来帮助您配置类似 UIDatePicker 的界面，但可以从中选择自定义值。
