let vc = UIViewController()
vc.tabBarItem.title = "sample"
vc.tabBarItem.image = UIImage(imageLiteralResourceName: "image.png").withRenderingMode(.alwaysOriginal)
vc.tabBarItem.selectedImage = UIImage(imageLiteralResourceName: "image.png").withRenderingMode(.alwaysOriginal)
        
// for text displayed below the tabBar item
UITabBarItem.appearance().setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.black], for: .selected)

Answer 2

Swift 3.0

I created the tabbar class file and wrote the following code

In viewDidLoad:

self.tabBar.barTintColor = UIColor.white
self.tabBar.isTranslucent = true

let selectedColor   = UIColor.red
let unselectedColor = UIColor.cyan

UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: unselectedColor,NSFontAttributeName: UIFont(name: "Gotham-Book", size: 10)!], for: .normal)
UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: selectedColor,NSFontAttributeName: UIFont(name: "Gotham-Book", size: 10)!], for: .selected)

if let items = self.tabBar.items {
    for item in items {
        if let image = item.image {
            item.image = image.withRenderingMode( .alwaysOriginal )
            item.selectedImage = UIImage(named: "(Imagename)-a")?.withRenderingMode(.alwaysOriginal)
        }
    }
}

After viewDidLoad:

   override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {

   if(item.title! == "title")
   {
    item.selectedImage = UIImage(named: "(Imagname)-a")?.withRenderingMode(.alwaysOriginal)

    }
    if(item.title! == "title")
    {
        item.selectedImage = UIImage(named: "(Imagname)-a")?.withRenderingMode(.alwaysOriginal)

    }
    if(item.title! == "title")
    {
        item.selectedImage = UIImage(named: "(Imagname)-a")?.withRenderingMode(.alwaysOriginal)

    }
    if(item.title! == "title")
    {
        item.selectedImage = UIImage(named: "(Imagname)-a")?.withRenderingMode(.alwaysOriginal)

    }
    if(item.title! == "title")
    {
        item.selectedImage = UIImage(named: "(Imagname)-a")?.withRenderingMode(.alwaysOriginal)

    }

}

in view did load method you have to set the selected image and other image are showing with RenderingMode and in tab bar delegate methods you set the selected image as per title

This Code works for Swift 4 if you want to change the image of Tab Bar Item when pressed. Copy and paste in the first viewDidLoad method that is hit in the project

   let arrayOfImageNameForSelectedState:[String] = ["Image1Color", "Image2Color","Image3Color"]
   let arrayOfImageNameForUnselectedState: [String] = ["Image1NoColor","Image2NoColor","Image3NoColor"]


    print(self.tabBarController?.tabBar.items?.count)

    if let count = self.tabBarController?.tabBar.items?.count {
        for i in 0...(count-1) {
            let imageNameForSelectedState   = arrayOfImageNameForSelectedState[i]
            print(imageNameForSelectedState)
            let imageNameForUnselectedState = arrayOfImageNameForUnselectedState[i]
            print(imageNameForUnselectedState)
            self.tabBarController?.tabBar.items?[i].selectedImage = UIImage(named: imageNameForSelectedState)?.withRenderingMode(.alwaysOriginal)
            self.tabBarController?.tabBar.items?[i].image = UIImage(named: imageNameForUnselectedState)?.withRenderingMode(.alwaysOriginal)
        }
    }

In Swift 5 ioS 13.2 things have changed with TabBar styling, below code work 100%, tested out.

Add the below code in your UITabBarController class.

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        let appearance = UITabBarAppearance()
        appearance.backgroundColor = .white

        setTabBarItemColors(appearance.stackedLayoutAppearance)
        setTabBarItemColors(appearance.inlineLayoutAppearance)
        setTabBarItemColors(appearance.compactInlineLayoutAppearance)

        setTabBarItemBadgeAppearance(appearance.stackedLayoutAppearance)
        setTabBarItemBadgeAppearance(appearance.inlineLayoutAppearance)
        setTabBarItemBadgeAppearance(appearance.compactInlineLayoutAppearance)

        tabBar.standardAppearance = appearance
 }

@available(iOS 13.0, *)
private func setTabBarItemColors(_ itemAppearance: UITabBarItemAppearance) {
    itemAppearance.normal.iconColor = .lightGray
    itemAppearance.normal.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.gray]

    itemAppearance.selected.iconColor = .white
    itemAppearance.selected.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.orange]
}

@available(iOS 13.0, *)
private func setTabBarItemBadgeAppearance(_ itemAppearance: UITabBarItemAppearance) {
    //Adjust the badge position as well as set its color
    itemAppearance.normal.badgeBackgroundColor = .orange
    itemAppearance.normal.badgeTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
    itemAppearance.normal.badgePositionAdjustment = UIOffset(horizontal: 1, vertical: -1)
}
