I am trying to either default an ios app to a particular brightness when its opened. Is this possible? If so what packages do I need to use?

If this is not possible can I have a brightness scroll bar within the app itself?

Thank you!

To set screen brightness, Try this code

UIScreen.main.brightness = CGFloat(0.5)

You can check this article. 

import UIKit
extension UIScreen
{
    static func setMainBrightness(brightness: CGFloat)
    {
        guard (0...1).contains(brightness) else
        {
            print("Attempt to set the screen brightness to an invalid value: \(brightness) should be between 0 and 1 inclusive.")
            return
        }
        self.main.brightness = brightness
    }
}
