RowView. xib

In iOS development, an exception occurs when XIB is enabled.

He said that the selector could not be found. Have you deleted the controller file connected to the xib by mistake? Or you mistakenly assigned the xib to other controllers when modifying the xib attribute...
No. Just re-create an xib. Maybe not all xib is hard to do... right?

How can I visually edit a UIView for ios development? Why must the uiview in the xib file be full screen?

UIVIew can be adjusted in xib. You can set the Attribute Editor on the right side of xcode.
