Change color of Back button in navigation bar

I am trying to change the color of the Settings button to white, but can't get it to change.

I've tried both of these:

navigationItem.leftBarButtonItem?.tintColor = UIColor.whiteColor()
navigationItem.backBarButtonItem?.tintColor = UIColor.whiteColor()

but no change, it still looks like this:

How do I make that button white?


[1]:

In SwiftUI, do the following:

Define a BackButton struct:
```
struct BackButton: View {
@Environment(\.presentationMode) var presentationMode
var body: some View {
Button(action: {
presentationMode.wrappedValue.dismiss()
}) {
HStack {
Image(systemName: "chevron.left")
.foregroundColor(.white)
Text("Back")
.foregroundColor(.white)
}
}
}
}

```

In the second view, use it as follows:
```
struct SecondView: View {
var body: some View {
VStack {
Text("Second View")
}
.navigationBarTitle("Second View", displayMode: .inline)
.navigationBarBackButtonHidden(true)
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
BackButton()
}
}
}
}
```

For some reason it isn't working for me programmatically. However setting it in the storyboard works every time.

**Swift 5 Updated**

If you need to set `Back` button color globally, you could simply use:

UIBarButtonItem.appearance().tintColor = Asset.pureWhite.color

Then you do not need to set back button background color on each view controller. If you use this one you **COULD NOT SET BACK BUTTON COLOR ON ANOTHER VIEW CONTROLLER**

**BUT**

If you need to set Back button color on view controller or change on another view controller do not use above method. You could use:

let appearance = UINavigationBarAppearance()
appearance.titleTextAttributes = [.font:FontFamily.BatonTurbo.medium.font(size: 20),
.foregroundColor: Asset.pureWhite.color] // Naviagtion Title attributes
appearance.backgroundColor = .red // Navigation bar background color

self.navigationItem.standardAppearance = appearance
self.navigationItem.scrollEdgeAppearance = appearance
self.navigationItem.compactAppearance = appearance

navigationController?.navigationBar.tintColor = .green // Back button color

Swift 5.5
---------

**Change complete app theme**

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Set for app
UINavigationBar.appearance().tintColor = .white
return true
}

**Change specific controller**

let navController = UINavigationController.init(rootViewController: yourViewController)
navController.navigationBar.tintColor = .red

present(navController, animated: true, completion: nil)

If you tried many times but could not work, you may try :
```
UIBarButtonItem.appearance(whenContainedInInstancesOf: [UINavigationBar.self]).tintColor = .red
```
Actually, I tried many times, only found this way will work.

I'm using this in swift 5 and worked for me

navigationItem.backBarButtonItem?.tintColor = UIColor(named: "uberRed")

**Swift 5.3:**

UINavigationBar.appearance().backIndicatorImage = UIImage(named: "custom-back-image")
UINavigationBar.appearance().backIndicatorTransitionMaskImage = UIImage(named: "custom-back-image")

self.navigationController?.navigationBar.tintColor = UIColor.black // to change the all text color in navigation bar or navigation
self.navigationController?.navigationBar.barTintColor = UIColor.white // change the navigation background color
self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.black] // To change only navigation bar title text color

I prefer custom NavigationController rather than setting global ui, or put in ViewController.

Here is my solution
```swift

class AppNavigationController : UINavigationController {

override func viewDidLoad() {
super.viewDidLoad()
self.delegate = self
}

override func viewWillAppear(_ animated: Bool) {

}

}
extension AppNavigationController : UINavigationControllerDelegate {

func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
let backButtonItem = UIBarButtonItem(
title: " ",
style: UIBarButtonItem.Style.plain,
target: nil,
action: nil)
backButtonItem.tintColor = UIColor.gray
viewController.navigationItem.backBarButtonItem = backButtonItem
}

func navigationController(_ navigationController: UINavigationController, didShow viewController: UIViewController, animated: Bool) {

}

}

```
Also you don't need to mess with Apple Api like **EKEventEditViewController**,**PickerViewController** and so on if you use global settings ui like ```UIBarButtonItem.appearance().tintColor = .white```
