[Crash] Content View returned an invaild size

[Crash] Content View returned an invaild size

 

 

크래시 분석

- Compositional Layout을 사용할 때 item, group의 width 혹은 height을 모두 estimated로 둔 상태에서 Cell 내부의 레이아웃을 제대로 잡아주지 않은 경우에 발생.

- 혹은 ContentConfiguration을 사용할 때 레이아웃 구성상 intrinsiccontentsize을 통해 View의 크기를 결정할 수도 있는데, 값을 넣어주지 않을 때도 발생.

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Content view returned an invalid size {1.7976931348623157e+308, 1.7976931348623157e+308} from -systemLayoutSizeFittingSize:withHorizontalFittingPriority:verticalFittingPriority: which is not allowed.
