Very thin line between Collection View Cells

Question

I am seeing a very thin white line in between my collection view cells, even though I have set section insets to 0 and defined the collection view cell to be self.view.bounds.size.width/2 (there should be two cells per row next to each other).

(You may have to open the image in full-view to see the white line highlighted in blue).

This is visible on a physical iPhone X device.

What is minimumInteritemSpacing? – Swamper

@Swamper the minimumInteritemSpacing is 0 – Tripod

Does this line visible only in iPhone X? – Swamper

@Swamper I also tested on an iPhone 8 and it's visible. – Tripod

If minimumInteritemSpacing == 0, I assume that the line is from cell. Can you show your code how to configure cell layout and collection layout? – Swamper

try it Objective-C: minimumInteritemSpacing = CGFLOAT_MIN; swift: minimumInteritemSpacing =CGFloat.leastNormalMagnitude – Shermy

I am experiencing a similar behaviour on iPhone 5s when presenting 3 cells per row. A very thin line appears between the second and third cell. When presenting 2, 4, 5, 6 cell per row everything is fine. It could be some rounding issue, but I still haven't found a way to fix it. – Flyman

What kind of layout does this collection view use? – Aftertaste

@Tripod were you ever able to figure this out? – Carter

Answer 1

I was able to fix that by setting minimumInteritemSpacing to -2 and adding +1 to the cell width. Don't know if it's cover all edge cases but it's working for my issue. Hope that this will help someone else
