Table View not returning data - ios

Question

I'm a student iOS dev, and I'm trying to control a tableview in a collection view cell that is returning 3 (or more) tableviews so I can have multiple tableviews. I believe I implemented everything right but no data is returned to the individual tableviews I have set the reuseidentifiers in the prototype cells in the tableview, and also the delegate and datasource are set to the VC.
var tableView1: UITableView?
var tableview2: UITableView?
// MARK: - Table view data source
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
if tableView == tableView1 {
return 2;
} else if tableView == tableview2 {
return 3
}
return 0;
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
if tableView == tableView1 {
return 2;
} else if tableView == tableview2 {
return 1;
}
return 0;
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)
if tableView == tableView1 {
cell = tableView.dequeueReusableCellWithIdentifier("testcell1", forIndexPath: indexPath) as! UITableViewCell
} else if tableView == tableview2 {
cell = tableView.dequeueReusableCellWithIdentifier("testcell2", forIndexPath: indexPath) as! UITableViewCell
}
// Configure the cell...
if tableView == tableView1 {
cell.textLabel?.text = "Homeroom"
cell.detailTextLabel?.text = "8:15 AM - 9:00 AM"
cell.selectionStyle = .None
} else if tableView == tableview2 {
cell.textLabel?.text = "Test Table 2 "
cell.detailTextLabel?.text = "1:30 PM - 2:30 PM"
cell.selectionStyle = .None
}
return cell
}
//**Center collection cells in the middle**
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets {
let sideInset = (collectionView.frame.size.width - 650) / 2
return UIEdgeInsets(top: 0, left: sideInset, bottom: 0, right: sideInset)
}
}
//Card Scrolling datasource
extension SAHomeViewController: UICollectionViewDataSource {
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
return 1
}
//Number of cards on home screen
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 2
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cardcell", forIndexPath: indexPath)
// Configure collection view cell
return cell
}
Here is my project editor to be clearer.

You need to provide default return value in both the functions. Because compiler checking that the functions required Int value should be returned and in these functions if any condition doesn't matched it will not return anything.
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
if tableView == tableView1 {
return 2;
}
else if tableView == tableview2
{
return 3;
}
return 0; // here
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
if tableView == tableView1 {
return 2;
} else if tableView == tableview2 {
return 1;
}
return 0; // here
}
