Error | Thread 1: "Unable to activate constraint with anchors

Error Log

Thread 1: "Unable to activate constraint with anchors <NSLayoutXAxisAnchor:0x60000386c080 \"UIView:0x162f04470.leading\"> and <NSLayoutXAxisAnchor:0x60000385fd80 \"UIStackView:0x162e05ae0.leading\"> because they have no common ancestor.  Does the constraint or its anchors reference items in different view hierarchies?  That's illegal."

점검

1. UI를 잘 선언했는지 점검
2. Layout이 잘 잡혀있는지 점검
3. 그럼에도 Thread error가 뜬다?
   * UI의 confige부분을 점검 (빼먹지는 않았는지)... !
