swift – iOS 17 UIImageView tintColor issue

It would be helpful to attach the relevant code snippets where you are working with colors and applying them to a UIImageView when posting a your question

However i think your are facing a color space conversion issue from your description when trying to apply a picked color . You can convert the color to the desired color space before applying it to the tintColor . You can make an extension to convert the color to the desired color space:

import UIKit
    
    extension UIColor {
        func convertToSRGB() -> UIColor? {
            guard let ciColor = self.cgColor.converted(to: CGColorSpace(name: CGColorSpace.sRGB), intent: .defaultIntent, options: nil) else {
                return nil
            }
            return UIColor(cgColor: ciColor)
        }
    }
    
    // usage
    let pickedColor: UIColor = // color picked from UIColorPickerViewController
    if let sRGBColor = pickedColor.convertToSRGB() {
        imageView.tintColor = sRGBColor
    }

Above extension method convertToSRGB attempts to convert the color to the sRGB color space. You can then set the converted color as the tintColor for your UIImageView.

Note: color space conversions can sometimes lead to subtle changes in appearance, especially if the original color was outside the sRGB color space
