Adding table to navigation controller view programatically doesnt work

Question

When attempting to add a table to cover the entire view of a view controller like so:

func setConstraints(){

    self.view.addSubview(statisticsTable);

    statisticsTable.leftAnchor.constraint(equalTo: self.view.leftAnchor).isActive = true;
    statisticsTable.rightAnchor.constraint(equalTo: self.view.rightAnchor).isActive = true;
    statisticsTable.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true;
    statisticsTable.topAnchor.constraint(equalTo: self.view.topAnchor).isActive = true;
}

The table doesnt display. Am i correct to assume that by topAnchor in the context of a navigation controller we mean the top part of the view contrller view ( which is where the navigatio bar ends? ). This looks quite simple so im clearly missing something obvious here. Thank you.

whenever your creating a view in code and tries to add constraints to that view you have to remember to set the translatesAutoresizingMaskIntoConstraints

func setConstraints(){

    self.view.addSubview(statisticsTable);
    // try to add this before you add your constraints to the view
    statisticsTable.translatesAutoresizingMaskIntoConstraints = false

    statisticsTable.leftAnchor.constraint(equalTo: self.view.leftAnchor).isActive = true;
    statisticsTable.rightAnchor.constraint(equalTo: self.view.rightAnchor).isActive = true;
    statisticsTable.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true;
    statisticsTable.topAnchor.constraint(equalTo: self.view.topAnchor).isActive = true;
}

welcome. see if it works so you can check the question as right so it can help others as well. — Khalid Afridi, Oct 18 '17 at 09:20
