Using Adaptive Cards for iOS

Question

Hello,

I am trying to incorporate Adaptive Cards into my iOS project, and having some difficulties.

For customization of UI elements, I can't find the xib files (https://learn.microsoft.com/en-us/adaptive-cards/sdk/rendering-cards/ios/native-styling) or CustiomInputNumberRenderer.mm (https://learn.microsoft.com/en-us/adaptive-cards/sdk/rendering-cards/ios/extensibility) the documentation is talking about. I would like to set specific button sizes or button image size for example.

Also, images are not being rendered, is this because there is a size limit? The images are being sent via https.

Thank you
