tableView cell dynamic height only works properly after some scrolling

Question

I'm trying to set the height of my tableview cell based on the height of an image inside my cell, the cell is rendering properly if I scroll a little up and down otherwise it is not getting updated, I have set all necessary constraint the image view (leading, trailing, top, bottom).

and i'm setting the image in my cellforrowat I have set rowHeight as UITableViewAutomaticDimension

I have tried these solution
1. aspect constraint 2. dynamic cell height scrolling issues solutions

please try Your bottom constrain do greater then equal to instead of equal to. — Yogesh Patel, Feb 24 '20 at 13:40
you need to let tableview know about changes in your cell layout, this should be mentioned somewhere among answers to these linked questions, but you should call tableView.beginUpdates()/tableView.endUpdates() for this. — Konstantin Oznobihin, Feb 24 '20 at 14:05
@FazalrahmanPuliyanchali after changing height of your cell, like you load an image, update cell layout so that image would fit in it and then you tell your table to update. — Konstantin Oznobihin, Feb 24 '20 at 14:30
Are there any constraints which is failing while your cell is created? Can you please share them? — Manoj, Feb 25 '20 at 07:43
can you show me your cell XIB along with constraints. Also do you load the image async from backend? — Manoj, Feb 26 '20 at 07:08
Hii not the height constrain bottom constrain of UIImageView ? — Yogesh Patel, Feb 26 '20 at 13:03
@FazalrahmanPuliyanchali as I already mentioned you need to update table after you updated cell layout not in viewDidLoad, or any other unrelated place. — Konstantin Oznobihin, Feb 27 '20 at 08:53

make sure you have set top-bottom constraints in storyboard.
save the thumbnail image as data to local storage (I'm using core data)
using the thumb image, calculate the aspect of the image
customise the row height as you want in heightForRowAt method.
