Custom TableViewCells do not show up - ios

Question

So I am pretty new to iOS development. I try to create everything programmatically so my Storyboard is empty. I'm currently trying to get a TableView with custom cells. The TableView is running and looking fine when I use the standard UITableViewCell. I created a very simple class called "GameCell". Basically, I want to create a cell here with multiple labels and maybe some extra UIObjects in the future (imageView etc.). For some reason, the custom cells do not show up.
Game cell class:
class GameCell: UITableViewCell {
var mainTextLabel = UILabel()
var sideTextLabel = UILabel()
func setLabel() {
self.mainTextLabel.text = "FirstLabel"
self.sideTextLabel.text = "SecondLabel"
}
}
Here the additional necessary code to get the number of rows and return the cells to the TableView which I have in my ViewController. self.lastGamesCount is just an Int here and definitely not zero when I print it.
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.lastGamesCount
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: cellID) as! GameCell
In my viewDidLoad() I register the cells like this:
tableView.register(GameCell.self, forCellReuseIdentifier: cellID)
When I run everything the Build is successful I can see the navigation bar of my App and all but the TableView is empty. I go back to the normal UITableViewCell and the cells are showing up again. What am I missing here? Any help is appreciated.
Thanks!

The problem is you need to set constraints for these labels
var mainTextLabel = UILabel()
var sideTextLabel = UILabel()
after you add them to the cell
class GameCell: UITableViewCell {
let mainTextLabel = UILabel()
let sideTextLabel = UILabel()
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
setLabel()
}
func setLabel() {
self.mainTextLabel.translatesAutoresizingMaskIntoConstraints = false
self.sideTextLabel.translatesAutoresizingMaskIntoConstraints = false
self.contentView.addSubview(mainTextLabel)
self.contentView.addSubview(sideTextLabel)
NSLayoutConstraint.activate([
mainTextLabel.leadingAnchor.constraint(equalTo: self.contentView.leadingAnchor),
mainTextLabel.trailingAnchor.constraint(equalTo: self.contentView.trailingAnchor),
mainTextLabel.topAnchor.constraint(equalTo: self.contentView.topAnchor,constant:20),
sideTextLabel.leadingAnchor.constraint(equalTo: self.contentView.leadingAnchor),
sideTextLabel.trailingAnchor.constraint(equalTo: self.contentView.trailingAnchor),
sideTextLabel.topAnchor.constraint(equalTo: self.mainTextLabel.bottomAnchor,constant:20),
sideTextLabel.bottomAnchor.constraint(equalTo: self.contentView.bottomAnchor,constant:-20)
])
self.mainTextLabel.text = "FirstLabel"
self.sideTextLabel.text = "SecondLabel"
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
