Feed() using collection view's sizeForItemAt delegate selector crashes on iOS 13

[heyflavio]

This issue was checked on iOS 13 versions. The same issue doesn't happen on iOS 14.

When implementing the feed() under the following parameters:

.feed(
        property: Property<Void>(()),
        to: #selector(UICollectionViewDelegateFlowLayout.collectionView(_:layout:sizeForItemAt:)))

And the stacktrace says the issue is regarding line 63 of BNDProtocolProxyBase:

signature = [NSMethodSignature signatureWithObjCTypes:description.types];

where:

Exception NSException * "+[NSMethodSignature signatureWithObjCTypes:]: type signature is NULL." 0x00006000015425b0
