Identical constraints on identical images, different behaviour? - ios

Question

I'm using the same image inside different imageviews, with the same constraints, yet somehow, last 2 images don't keep aspect ratios, despite constraints.
Here's the constraint code.
PS: all of them have the following 2 lines. (I just removed those lines from each group to avoid wall of code).
.contentMode = .scaleAspectFit
.translatesAutoresizingMaskIntoConstraints = false
ImageLineEvents.topAnchor.constraint(equalTo: LabelTitleEvents.bottomAnchor, constant:UI_SPACING_SCROLL).isActive = true
ImageLineEvents.centerXAnchor.constraint(equalTo: ScrollView.centerXAnchor).isActive = true
ImageLineEvents.widthAnchor.constraint(equalTo: VC_UserProfile.view.widthAnchor).isActive = true
ImageLineEvents.widthAnchor.constraint(equalTo: ImageLineEvents.heightAnchor, multiplier: (ImageLineEvents.image?.size.width)! / (ImageLineEvents.image?.size.height)!).isActive = true
ImageLineUpdates.topAnchor.constraint(equalTo: LabelTitleUpdates.bottomAnchor, constant:UI_SPACING_SCROLL).isActive = true
ImageLineUpdates.centerXAnchor.constraint(equalTo: ScrollView.centerXAnchor).isActive = true
ImageLineUpdates.widthAnchor.constraint(equalTo: VC_UserProfile.view.widthAnchor).isActive = true
ImageLineUpdates.widthAnchor.constraint(equalTo: ImageLineUpdates.heightAnchor, multiplier: (ImageLineUpdates.image?.size.width)! / (ImageLineUpdates.image?.size.height)!).isActive = true
ImageLineSoon.topAnchor.constraint(equalTo: LabelTitleSoon.bottomAnchor, constant:UI_SPACING_SCROLL).isActive = true
ImageLineSoon.centerXAnchor.constraint(equalTo: ScrollView.centerXAnchor).isActive = true
ImageLineSoon.widthAnchor.constraint(equalTo: VC_UserProfile.view.widthAnchor).isActive = true
ImageLineSoon.widthAnchor.constraint(equalTo: ImageLineSoon.heightAnchor, multiplier: (ImageLineSoon.image?.size.width)! / (ImageLineSoon.image?.size.height)!).isActive = true
ImageLineToday.topAnchor.constraint(equalTo: LabelTitleToday.bottomAnchor, constant:UI_SPACING_SCROLL).isActive = true
ImageLineToday.centerXAnchor.constraint(equalTo: ScrollView.centerXAnchor).isActive = true
ImageLineToday.widthAnchor.constraint(equalTo: VC_UserProfile.view.widthAnchor).isActive = true
ImageLineToday.widthAnchor.constraint(equalTo: ImageLineToday.heightAnchor, multiplier: (ImageLineToday.image?.size.width)! / (ImageLineToday.image?.size.height)!).isActive = true
Everything is fine in portait mode, but when I turn to landscape, somehow last 2 images do not keep aspect ratios. I have logs from each orientation.
print("ar = \(Float((ImageLineEvents.image?.size.width)!) / Float((ImageLineEvents.image?.size.height)!))")
print("ar = \(Float((ImageLineUpdates.image?.size.width)!) / Float((ImageLineUpdates.image?.size.height)!))")
print("ar = \(Float((ImageLineSoon.image?.size.width)!) / Float((ImageLineSoon.image?.size.height)!))")
print("ar = \(Float((ImageLineToday.image?.size.width)!) / Float((ImageLineToday.image?.size.height)!))")
print("w = \(ImageLineEvents.frame.width)")
print("w = \(ImageLineUpdates.frame.width)")
print("w = \(ImageLineSoon.frame.width)")
print("w = \(ImageLineToday.frame.width)")
print("h = \(ImageLineEvents.frame.height)")
print("h = \(ImageLineUpdates.frame.height)")
print("h = \(ImageLineSoon.frame.height)")
print("h = \(ImageLineToday.frame.height)")
These are from portrait and everything is as expected.
ar = 162.5
ar = 162.5
ar = 162.5
ar = 162.5
w = 335.0
w = 335.0
w = 335.0
w = 335.0
h = 2.0
h = 2.0
h = 2.0
h = 2.0
Yet if I turn to landscape, last 2 have different results.
ar = 162.5
ar = 162.5
ar = 162.5
ar = 162.5
w = 684.0
w = 684.0
w = 684.0
w = 684.0
h = 4.33333333333333
h = 4.33333333333333
h = 4.0 (Why is this not 4.33 ???)
h = 4.0 (Why is this not 4.33 ???)
I looked millions of times but I still can't figure out what's wrong with this. There are no constraint errors. Visually, last 2 images do not go all over the edges, because they keep aspect ratios, yet somehow the height is lower. They are all inside a ScrollView, but I don't see how that can matter. Any help ?
EDIT:
I've added the visual result. First 2 constraints are the first image, last 2 are the last image. As you can see, their widths are not the same in landscape. The image in question is the line just below the title and it should spread from title leading to dot image trailing. All of them behave well on portrait, yet on landscape, last 2 behave differently.
