Answer 1

In Your PhotoCell class, add this snippet code.
override func didMoveToSuperview() {
layoutIfNeeded()
}

Answer 2

Your problem is in the section where you define your tableView.
In your tableView extension, you set the numberOfSectionsInTableView method to return 3 rows, so your code defining the cell dimensions only runs on the first 3 rows.
Try setting your numberOfSections method to the number of rows you want based on the dimensions of your view, it looks to be about 5.
