Check out this lovingly crafted Apple Music-style popup library. SPAlert is written in clean, beautiful, modern Swift code by Ivan Vorobei, a prolific and talented open source developer.

If the presets don't fit your needs, you can customize the popups with custom images and duration. Includes support for light and dark modes, and installable via Swift Package Manager and CocoaPods.
