how can I correctly get the tableCell value to next tableCell

I'm new here and new to swift .now I'm creating an invoice app so I need to display the invoiceViewController in next ViewController but the cells for the bills in invoice are not coming correctly to next page like being an rangeProblem. I have tried severMethod but I'm getting disappointed . could any one hear help me!..

this is my InvoiceViewController

I have tried for this cells displaying in next ViewController cell but it showing in incorrect manner of being incorrect range.

I will share my simulator screenshots so you guys can point out what I'm saying and my problem.

This the detail controller.
