ios – Fundamental Thread Checker: UI API known as on a background thread: -[UIImagePickerController didDisplayPhotoPickerSourceType:]

Upon clicking on the navigationItem which opens a UIImagePickerController, I get the under log within the debugger, and can’t discover any documentation that speaks about didDisplayPhotoPickerSourceType. Be aware I’m presenting the picker from the primary thread and nonetheless getting this important thread situation.

partial code:

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

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

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