App crashing when using background image for navigation bar in iOS

Question

I am using background image for the navigation bar. And it is crashing my app while presenting a view controller. I am also having the background image for all the view controller's view. I am using implementing like this

func setNavigationAppearance(tintColor : UIColor, barTintColor : UIColor?) {
    let navigationBarAppearace = appDelegateObj.navigationController!.navigationBar

    navigationBarAppearace.tintColor = tintColor
    navigationBarAppearace.barTintColor = barTintColor
    navigationBarAppearace.translucent = false

    //navigationBarAppearace.
    //Settign the Custome Font and TextColor

    if let font = UIFont(name: FontCustom.Regular, size: 17) {
        UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName: font ,NSForegroundColorAttributeName : tintColor]
    }
}

I call this method with this image let navigationColor : UIColor = UIColor(patternImage: UIImage(named: AppImagesName.PatternRed)!)

And I am getting these crash logs.

terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Only RGBA or White color spaces are supported in this situation

I Googled about this, all are saying that remove the background image or this is iOS bug.

So please let me know what could be the solution.

To set background image to NavigationBar, use the following code:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

        if let myImage = UIImage(named: "navBarImage.jpg"){
            UINavigationBar.appearance().setBackgroundImage(myImage, for: .default)
        }


        return true
    }
