Main Thread Checker: UI API called on a background thread: -[UIImagePickerController didDisplayPhotoPickerSourceType:]

Question

Upon clicking on the navigationItem which opens a UIImagePickerController, I get the below log in the debugger, and cannot find any documentation that speaks about didDisplayPhotoPickerSourceType. Note I am presenting the picker from the main thread and still getting this main thread issue.

partial code:

 ...
 override func viewDidLoad() {
    super.viewDidLoad()
    collectionView.backgroundColor = .blue
    register()
    setUp()
    collectionView.reloadData()
}

private func setUp() {
    navigationController?.isNavigationBarHidden = false
    let layout = collectionView.collectionViewLayout as! UICollectionViewFlowLayout
    layout.minimumInteritemSpacing = 2
    layout.minimumLineSpacing = 2
    collectionView.collectionViewLayout = layout
    
    navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addNewPerson))
}

@objc private func addNewPerson() {
    DispatchQueue.main.async { [weak self] in
        let picker = UIImagePickerController()
        picker.allowsEditing = true
        picker.delegate = self
        self?.present(picker, animated: false)
    }
}
...
