Hello,

By searching for this third-party package , its compatible target framework(s) doesn't contain MAUI (.net-ios), so you cannot use it.

In addition, TVIAppScreenSource is a class in the Twilio iOS SDK, the error you got is caused by the null object in native iOS. Please connect the owners for further help, and they list their GitHub Repo, you could try to get support there.

(I also search for some other iOS binding libraries about twilio, they don't support MAUI)

Best Regards,

Wenyan Zhang
