Status bar allowing the contents of UITableView through it!

Hello,
I am noob iOS developer, sorry if this question is too basic.
I am observing a peculiar problem in my project
not seen in other similar screens of the app. I have a UITableView with upto 100 items but when I scroll to view additional content
the Status bar is allowing the contents of UITableView through it. I have tried few things based on stackoverflow research , I set

tableview.contentInset.top = 20

and it did not work

I also attempted to set following in viewcontroller

self.edgesForExtendedLayout = []
self.extendedLayoutIncludesOpaqueBars = false
self.automaticallyAdjustsScrollViewInsets = false

None of these helped. I will appreciate if someone can give me any direction on how to solve this problem. Also I would like to deepen my understanding to solve similar problems
what are some topics I need to brush up for sure?

Thanks
