The App works fine on the simulator.

When I run it on my iPhone, the image is picked out fine and it even displays the image.

But the Label which should say 'Unknown' initially is not visible. When I use Rename from the UIAlertController, I present another alert controller with a text field for name.

As soon as I type the first letter in the text field, an error shows up in my Xcode console: 2020-07-21 13:19:24.679451+0530 Project10[33091:14325443] [general] Connection to daemon was invalidated

Here is my didSelectItemAt:

override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    let person = people[indexPath.item]

    let ac = UIAlertController(title: nil, message: nil, preferredStyle: .alert)
    ac.addAction(UIAlertAction(title: "Rename", style: .default){
        [weak self] _ in

        let ac1 = UIAlertController(title: "Rename Person", message: nil, preferredStyle: .alert)
        ac1.addTextField()

        ac1.addAction(UIAlertAction(title: "Save", style: .default){
            [weak self,weak ac1] _ in
            guard let newName = ac1?.textFields?[0].text else {return}
            person.name = newName
            self?.collectionView.reloadData()
        })

        ac1.addAction(UIAlertAction(title: "Cancel", style: .cancel))

        self?.present(ac1,animated: true)
    })

    ac.addAction(UIAlertAction(title: "Delete Person", style: .destructive){
        [weak self] _ in
        self?.people.remove(at: indexPath.item)
        self?.collectionView.reloadData()
    })

    ac.addAction(UIAlertAction(title: "Cancel", style: .cancel))
    present(ac,animated: true)

}
