'UITableView method cellForRowAtIndexPath not called

My UITableView isn't showing any data. I think the problem is in:

override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath?) -> UITableViewCell?`

This is my code:

override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath?) -> UITableViewCell? {
    // Configure the cell...
    let cellId: NSString = "Cell"
    var cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier(cellId) as UITableViewCell

    if let ip = indexPath {
        //var data: NSManagedObject = myList[ip.row] as NSManagedObject
        //cell.textLabel.text = data.valueForKey("name") as String
        cell.textLabel.text = "Hi"
    }
    return cell
}

I've seen tutorials on youtube that use this code, but I can't get it to work.

First I fought it was a problem with my array, but when i just put text in it it still doesn't show anything.

I'm running Xcode6 beta 3, but this code did run perfectly fine in beta 2.

I don't have any warning or error messages.

EDIT: I looked up some other Swift projects of me, I got the same function in there and it worked 2 weeks ago but now it also doesn't work. Maybe this is a Xcode6 beta 3 issue?

My class is of type UITableViewController.

EDIT: I was looking through the Apple developer forums and saw related issues after updating to xCode 6 beta 3, so it's likely a problem with xCode 6 beta 3!

EDIT: The method doesn't get called.

Got it!

Had the same problem - I also have added a tableview into a uiviewcontroller and it also not worked, but I know the problem now.

If you add the tableview on interface builder AND click after that "Add Missing Constraints", it'll add constraints that can't work together.

At my position I had the tableview on my whole uiview and after click on "Add Missing Constraints", it will add this here:

enter image description here

And now if you delete one of the Trailing or Leading Alignments, it will work - cellforrowatindexPath will get called! Don't know why it is like that, but it will work.

Hope I can help you.

You need to implement this or cellForRowAtIndexPath will never be called:

override func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int {
  // Return the count of the number of rows in the table
  return 5
}

The 5 is just an example of course. You would return the count of the number of elements in your array.

Solution 3:^[3]

Check if you have these lines:

tableView.delegate = self
tableView.dataSource = self

If dataSource = self is not implemented it could be a reason of not called cellForRowAt indexPath method

Seem's that there isn't a solution for this. Returned to xCode 6 beta 2 fixed the issue. Hopefully and likely it will get patched in Beta 4.

Solution 5:^[5]

May be this will help you.

I have the following:

self.myTableView.rowHeight = 60
in function heightForHeaderInSection: return 60
cellForRowAtIndexPath is not called

if a value >= 60 is returned in heightForHeaderInSection the cellForRowAtIndexPath is not called.

Even when I set self.myTableView.rowHeight = 59 (or 59 or 58), if I return in heightForHeaderInSection a value >= 60 the cellForRowAtIndexPath is not called.

So, I return a value <= 59 in function heightForHeaderInSection and the cellForRowAtIndexPath is then called. (use breakpoints in cellForRowAtIndexPath to check this).

Another issue: If cellForRowAtIndexPath is called but you don´t see the rows of your tableView: This is because the height of your tableView is too short.

For example: (in this case titulo_tabla is a UILabel that I have above my table. aOrdenes is an NSArray from which I get the count of rows that I show).

var width = self.view.frame.size.width
var height = self.view.frame.size.height
... 
myTableView.frame = CGRectMake(width * 0.03, titulo_tabla.frame.origin.y + titulo_tabla.frame.height, width - 2 * (width * 0.03), 60.0 * CGFloat(aOrdenes.count) + 50)

In the last code, the last parameter ..., 60.0 * CGFloat(aOrdenes.count) + 50) the 60 is the rowHeight (self.myTableView.rowHeight = 60) and the 50 is the value returned in function heightForHeaderInSection. With this your tableView rows are showed.

XCode Version 6.3.1 (6D1002) I'm just run into this issue, In my case is I duplicate UITableViewController and reuse it somewhere cause this problem.

My solution is

Create new UITableViewController
Duplicate only UITableViewCell
Clear all constraints (not sure you will need this but for me it's mess up)
In my case "Add missing constraints" and "Reset to suggestion constraints" is mess up so I manually add it.

Nothing to do with datasource btw, you can simply add some foo content to some label in cell to separated problem.

HTH

Maybe you have declare delegate in init:

-(instancetype)init{
self = [super init];
if(self){
    _tableView.delegate = self;
    ,...
    }
return self;

}

Should be call it in ViewDidload:

- (void)viewDidLoad {
[super viewDidLoad];
_tableView.delegate = self;

,... }

Solution 8:^[8]

You must make sure that the datasource is correctly assigned and that you use the correct method signature. You declared some optionals wrong.

func tableView(tableView: UITableView!,
cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { }

Solution 9:^[9]

I had the same frustrating issue when I migrated my old Swift 2.3 code developed in Xcode 8.2.1 to Swift 3.0 in Xcode 8.3, for me numberOfRows was getting called

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
   return 2
}

but the main data source methods will never get called,

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

The main issue was the UITableView I had created via Swift code was not added to any view, it was added but replaced by another view later so the data source method was never called. Hope it helps someone.

Solution 10:^[10]

override func tableView(_ tableView: UITableView!,
cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { }

I was missing the underscore in as the first parameter tableView.

It also probably needed the override. You will know if you got the func described correctly if the override works.

Solution 11:^[11]

you need to set the height constraint for you table view. You can set in storyboard or programmatically. If you need then i will post a running example.

Solution 12:^[12]

Make sure you hav setup delegate and datasource property for the UITableView object.

Solution 13:^[13]

You need to set tableview in editing mode in viewDidLoad

tableView.setEditing(true, animated: true)

Solution 14:^[14]

I had the same problem weird thing is Numbers of Rows method is getting called but cellForRowAtIndex is not getting called. In my case it is all due to the storyboard constraints and make sure tableiew is not hidden and is installed on the storyboard
