Thread 1: Fatal error: Index out of range, return array.count + 1 - swift

Question

I have a tableview with at all times one cell. If there is data to download from Firebase it will put it in an array called posts. When there's for example, two "in my case" servers that the user will download, it will only display one cell instead of two. I thought I could fix this by changing return posts.count to return posts.count + 1 because of the one cell that will be shown at all times. But if I use return posts.count + 1 I will get a
Thread 1: Fatal error: Index out of range
error on line let post = posts[indexPath.row]. I have read about this error, but I can't seem to fix it.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if posts.count == 0 {
self.tableView.setEmptyMessage("No Servers uploaded!")
return 1
} else {
self.tableView.restore()
return posts.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "ProfileCell", for: indexPath) as! ProfileCellTableViewCell
cell.delegate = self
return cell
}else {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! TableViewCellMYposts
cell.Map_image.image = nil
let post = posts[indexPath.row]
cell.post = post
cell.delegate = self
return cell
}
}

Answer 1

Assuming you have some piece of data in posts[0], you are never actually displaying it. For indexPath.row = 0, you are displaying a profile cell, and then you start displaying the data from posts[1] and on. Change your problem line to:
let post = posts[indexPath.row - 1]
