For iOS develop,the debug view hierarchy didn't work

when I click the debug view hierarchy in Xcode, it shows nothing and the console alert:

Assertion failure in -[UITextView _firstBaselineOffsetFromTop], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit/UIKit-3512.60.12/UITextView.m:1683

what confused me is that all my project just this viewController occur it.

It's my first time meeting this, could anyone give me some advice.

From Assertion failure in UITextView _firstBaselineOffsetFromTop

Write below in your project.

For obj-C

@interface UITextView(MYTextView)

@end

@implementation UITextView (MYTextView)
- (void)_firstBaselineOffsetFromTop {

}

- (void)_baselineOffsetFromBottom {

}
@end

For swift

extension UITextView {
    func _firstBaselineOffsetFromTop() {
    }
    func _baselineOffsetFromBottom() {
    }
}
