Why is Chromecast SDK for iOS so big when installed with Cocoapods?

问题

I recently added the Chromecast SDK to my project, and GoogleCast.framework is nearly 650MB.

Is that the normal size? If not, how can I decrease the size?

I installed it with Cocoapods (the google-cast-sdk pod) and my project is all in Swift.
