My trainer give me a simple task .
To delete a row in table view without delete function.
But by updating the height of the row using a Boolean value.
I know it's simple ....but was not able to do today.

What you didn't mention, is the caching. That's the most important part. Scrolling back and forth, being a lot more easier. Of course the cells will preload much faster, but their relod time will be even better, when were're tryig to reload older cells

[@iOSAcademy]

100% correct

[@hoanglongnguyen8856]

Perfect, can you make a Just Peek 3D touch Collectionview like Instagram video tutorial please

[@iOSAcademy]

Will do

[@amen652]

Hey I am still a bit confused as to the purpose of using the callback. Is that because in the 'prefectRowsAt' function, you pass nil for the completion of the viewModel?

[@iOSAcademy]

Correct

[@honglinhnguyen96]

Thank you very much for this video tutorial. I saw in the video that you call a Non-Escaping Closure in the completion of the URLSession (which is an Escaping Closure). This is not the same as your Escaping Closure video tutorial. Is the difference here Optional closure?
I am new and feeling a bit confused.
I'd appreciate it if you could help explain it. Thanks a lot.

[@iOSAcademy]

Optional closures are escaping by default
