I tried like so to add checkMark on cell but if I tap section 0 row 0, section 2 row 0 also checked. Also if tap section 0 row 1, section 3 row 0 checked(vise verse if I tap section 2 row 0, section 0 row 0 also checked also if tap section 3 row 0, section 0 row 1 checked).
And if scrolling fast all check goes away. How can I fix this? Thank you in advance!

A better way is to put checkMark setting logic inside cellForRow , as because of dequeuing un wanted cells may get checked , so in didSelectRow store Indexpath/s of one/s you want to check and reload the cell with the selected IndexPath
