[IOSDeveloperProgrammer]

@EzimetYusup Thanks for giving library! i need to populating tableview data.
func WTSviewOfTab(index: Int) -> UIView { let view:LeaveTableVC = LeaveTableVC() if index == 0 { view.view.backgroundColor = UIColor.black }

self.tableview.delegate = self
    self.tableview.dataSource = self,  `

Error: fatal error: unexpectedly found nil while unwrapping an Optional value

I was getting tableview.delegate = self (in leavetableVC class)
Please help me out this issue

@EzimetYusup sorry for late! I was busy with another project. #

When i was adding tableview on delegate method here
` func WTSviewOfTab(index: Int) -> UIView {

    let view:LeaveTableVC = LeaveTableVC()
    if index == 0 {
        view.view.backgroundColor = UIColor.black
    }
    else if index == 1 {
        view.view.backgroundColor = UIColor.gray
    }
    //        if index == 2 || index == 5{
    //            view.view.backgroundColor = UIColor.redColor()
    //
    //        }
    
    
    return view.view
}

`

leavetable.swift
super.viewDidLoad() self.tableview.delegate = self self.tableview.dataSource = self
