how to remove UITableView offset on the left in Swift

Question

I've found some questions and answers to remove offset of UITableViews in ios7, namely this one here How to fix UITableView separator on iOS 7?

I was wondering if anyone had come across the correct functions to remove inset margins. Something similar to this answer in objective-c

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

You can just set the property: tableView.separatorInset = UIEdgeInsetsZero

hey this should normally work with the tableview that I have, yet my table view still has the border included. it might be that something is overriding my setting – johnnywu Jul 16 '14 at 17:06

Just like the Objective-C example, but converted to swift. I had some trouble myself. This code works in a UITableView if you were doing it in a UITableViewController you would substitute self.tableView for self:

// iOS 7
if(self.respondsToSelector(Selector("setSeparatorInset:"))){
    self.separatorInset = UIEdgeInsetsZero
}

// iOS 8
if(self.respondsToSelector(Selector("setLayoutMargins:"))){
    self.layoutMargins = UIEdgeInsetsZero;
}

And for the cell (iOS 8 only) put the code below in the following function:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath)

get the cell, and set the following property:

// iOS 8
if(cell.respondsToSelector(Selector("setLayoutMargins:"))){
    cell.layoutMargins = UIEdgeInsetsZero;
}

Put the following lines in viewDidLoad()

tableView.layoutMargins = UIEdgeInsetsZero
tableView.separatorInset = UIEdgeInsetsZero

Now look for your cellForRowAtIndexPath method and add this:

cell.layoutMargins = UIEdgeInsetsZero

nowadays ".zero" syntax...

    tableView.layoutMargins = UIEdgeInsets.zero
    tableView.separatorInset = UIEdgeInsets.zero

    cell.layoutMargins = UIEdgeInsets.zero

You can do this via the console by modifying the "Default Insets" to be "Custom Insets"

Inside the table view cell click the slider icon
Under Table View Cell go to where Separator says "Default Insets"
Click the dropdown menu and select "Custom Insets"
Choose your left and right number (I have mine set to 0 for edge to edge divider)
