I am trying to get background color from an image in a class, problem is it gives me an error "invalid selector: Compound class names not permitted".

i tried many versions to get the color (rgb) and every time i get an error and i am confused already because i know there are several ways to do it and i cannot accomplish any.

HTML CODE:

I have a collection view that holds cells with image views. I trigger an animation when the user presses down on the image view (using touchesBegan), and another animation for when the user releases (using touchesEnded).

The animations work perfectly only if I hold down on my click then release (delayed click), but when I fast click, the animation jumps as if the duration was set to 0.

I believe the issue is because collection view is subclass of scroll view, and scrollViews "temporarily intercepts a touch-down event by starting a timer and, before the timer fires, seeing if the touching finger makes any movement. If the timer fires without a significant change in position, the scroll view sends tracking events to the touched subview of the content view."

https://developer.apple.com/documentation/uikit/uiscrollview#//apple_ref/doc/uid/TP40006922

From what I can gather, I think that the touch interception from the collection view is causing problems with the animation if the click is faster than the touch timer. When I test using a regular view instead of a collection view as the superview, the animation works perfectly and doesn't require a delayed click.

If this is the case, then how is the animation triggered for a fast-click at all? Moreover, how might I be able to tigger the animation without having to use a delayed click?

If this is not the case, then what might be the reason for this issue?

Here is my code for animation and touches:
