Add these extensions to your app.

import UIKit

public extension UITabBar {
    var tabBarButtons: [UIView] {
        let values = self.subviews.filter({ String(describing: type(of: $0)) == "UITabBarButton" })
        return values.sorted(by: { $0.frame.origin.x < $1.frame.origin.x })
    }
}

public extension UIView {
    var tabBarSwappableImageViews: [UIView] {
        let values = self.subviews.filter({ String(describing: type(of: $0)) == "UITabBarSwappableImageView" })
        return values.sorted(by: { $0.frame.origin.x < $1.frame.origin.x })
    }
}

Then call this on your tab bar controller

let imageView: UIImageView? = UITabBarController?.tabBar.tabBarButtons[YOUR_INDEX_HERE].tabBarSwappableImageViews.first

For first index its perfectly worked. But when used second index its failing return empty array. self.tabBarController?.tabBar.tabBarButtons[1].tabBarSwappableImageViews ▿ Optional> - some : 0 elements — kiran, Dec 17 '22 at 19:48
