Also if you have only one button with role n your alert, you don’t need another button to show Cancel. You get Cancel for free.

[@Jannemandevries]

What annoys me is that the alert buttons have a 400ms callback delay, while the closing animation is only 300ms. I managed to fix this (in UIKit), along with a couple of other quirks.

[@seanallen]

I didn't know this. Thanks for sharing.

[@dominikgrodl7822]

Out of curiosity, when is that an issue? Is it just the aesthetics of it, or something else entirely?

[@Jannemandevries]

@@dominikgrodl7822 If the callback code changes the ui it does it a bit too late imho making it feel sluggish. I'm close to a fix that also works on SwiftUI so stay tuned.

[@JasonMitchellAZ]

So easy.

[@seanallen]

Love the new iOS 15 way of doing these.

[@El_Batono]

thx, do more videos for creating ui components

[@seanallen]

Will do!
