My xib become clutter when I add JVFloatLabeledTextField into it.

I change those UITextField to JVFloatLabeledTextField in xib file at identity inspector tab on right panel named "Utilities" just like followed image.

When I compiled, it occured an issue like followed image.

But Xcode can run my project and my app perform correctly as my expectation. But now, my xib's display in a clutter, I mean it's all of property seem correctly just same before I replace my xib's UITextField to JVFloatLabeledTextField.

However, my xib's UI component element display disorderly, but I ensure their auto layout constraints are correct.

UIView(i5M-Pr-Fkt) is my controller's view. And my podfile used use_frameworks! already. Anyone might help me?
