DWURecyclingAlert Red alert while rendering images and cells... about layoutkit HOT 4 CLOSED

Thanks for reporting!

I am not familiar with DWURecyclingAlert but based on the README it triggers for two reasons:

Displays non-recycled UIView, CALayer and UIImage objects with bold red bolders.
Displays the time it takes to complete each time sensitive API calls, in milliseconds.

LayoutKit does not reuse views by default so my guess is that is causing the alert (and not necessarily that it is slow). 8ms doesn't seem that bad since the README also says this:

Your code usually has less than ten milliseconds to run before it causes a frame drop.

What hardware did you test on?

LayoutKit will reuse views if a layout has a viewReuseId. For the feed example, you can try adding viewReuseId parameters to all of the LabelLayouts and SizeLayout<UIImageView>s in ProfileCardLayout, FeedItemLayout, and ContentLayout to see (1) if that gets rid of the warning and more importantly (2) if it actually improves performance.

If it does improve performance, feel free to submit a PR to make those changes to the example layouts (they were created before viewReuseId existed).

Collecting this data would also help inform how beneficial #58 would be.

I experimented with viewReuseId and it does noticeably improve performance.

#63 updates the example layouts.

Excellent, Thank you Nick.

For clarification, if/when #58 is resolved it may not be necessary to specify viewReuseIds everywhere to get better performance (it would only be necessary for animations).
