These are the constraints on the detail view just after it has been added to
the StackView:
myDetailView.constraints: (
"<NSLayoutConstraint:0x600000081d60 H:|-(0)-[DetailHeaderView] (Names:
DetailHeaderView:0x6300001809c0, LTWDetailXView:0x630000180000,
'|':LTWDetailXView:0x630000180000 )>”,
"<NSLayoutConstraint:0x600000081c20 DetailHeaderView.trailing ==
DetailBodyView.trailing (Names: DetailHeaderView:0x6300001809c0,
DetailBodyView:0x6200001805b0 )>”,
"<NSLayoutConstraint:0x600000081b30 DetailHeaderView.leading ==
DetailBodyView.leading (Names: DetailHeaderView:0x6300001809c0,
DetailBodyView:0x6200001805b0 )>”,
"<NSLayoutConstraint:0x600000081a40 V:|-(1)-[DetailHeaderView] (Names:
DetailHeaderView:0x6300001809c0, LTWDetailXView:0x630000180000,

"<NSLayoutConstraint:0x600000081590 H:[DetailHeaderView]-(0)-| (Names:
LTWDetailXView:0x630000180000, DetailHeaderView:0x6300001809c0,

"<NSLayoutConstraint:0x600000081540 V:[DetailBodyView]-(0)-| (Names:
