• [x] dynamically expandable based on the content height
• [x] pan gesture to dismiss
• [x] tap gesture behind it to dismiss
• [x] custom transition animations / can be expandable
• [x] custom presentations; it can be presented at the bottom like a regular action sheet or centered as a modal

I've just tested this out and here is the report:

• i don't see a "swipe down" gesture to dismiss dialogue, and it should support interactive dismiss
• i would like to fixate the height of the dialogue, sometimes it half the screen height or any arbitrary height; the content should scroll inside dialogue
• when presenting the dialogue, there is some semitransparent background on the viewcontroller
• in the demo app, when use "simple animation" with "bottom" type, scrolling to the top will reveal the rootController at the bottom of the screen

Added:

• "swipe down to dismiss" interactive gesture.
• option to set a custom height
• fix for scrolling to the top will reveal the rootController at the bottom of the screen

Info regarding this issue:

when presenting the dialogue, there is some semitransparent background on the viewController

This is set in the demo project with: setDialogBackground() but I have removed it to avoid confusion.

I appreciate your work on this @markom-povio, but we have moved our focus towards SwiftUI components. Since this can be easily done with .sheet modifier, I'll close this PR.
