I have two table view controllers, the 2nd tableview controller contains entries with different option to add to the first view table view controller. The first table view controller rows have two swipe actions i.e. completed and delete.
Each row/cell has two labels one with the title of the option selected from 2nd table view controller and 2nd label is the date it was created.
When completed swipe action is tapped, strike through function strikes the text of the both the labels.
However, I am noticing that everytime I swipe an entry and delete it, then add the same entry again, it would automatically swipe the title label of the cell.
If I go back and relaunch the 1st view controller, it clears the stike.
This striking happens randomly i.e. it strikes sometimes and some times it does not strike and the strike through function is not even called.
Any suggestions are greatly appreciated.
