Navigation Bar:

<pre><code>navigationController?.navigationBar.barTintColor = UIColor.green
</code></pre>

Replace greenColor with whatever UIColor you want, you can use an RGB too if you prefer. 

Navigation Bar Text:

<pre><code>navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.orange]
</code></pre>

Replace orangeColor with whatever color you like.

Tab Bar:

<pre><code>tabBarController?.tabBar.barTintColor = UIColor.brown
</code></pre>

Tab Bar Text:

<pre><code>tabBarController?.tabBar.tintColor = UIColor.yellow
</code></pre>

On the last two, replace brownColor and yellowColor with the color of your choice.

<pre><code>UINavigationBar.appearance().backgroundColor = UIColor.greenColor()
UIBarButtonItem.appearance().tintColor = UIColor.magentaColor()
//Since iOS 7.0 UITextAttributeTextColor was replaced by NSForegroundColorAttributeName

<pre><code>UINavigationBar.appearance().backgroundColor = .green // backgorund color with gradient
// or
UINavigationBar.appearance().barTintColor = .green // solid color
 
UIBarButtonItem.appearance().tintColor = .magenta

I'm writing this for those that still have problems with the solutions here.

I'm using Xcode Version 11.4 (11E146). The one working for me is: 

<pre><code>navigationController?.navigationBar.barTintColor = UIColor.white
navigationController?.navigationBar.tintColor = UIColor.black
</code></pre>

BUT!, if you set the barTintColor in storyboard to any other value than "default" this 2 lines of code will have no effect.

So, be carefull and set back to default barTintColor in Storyboard.
Oh Apple...

If you're using iOS 13 or 14 and large title, and want to change navigation bar color, use following code:

<pre><code> fileprivate func setNavigtionBarItems() {

// let naviFont = UIFont(name: &quot;Chalkduster&quot;, size: 30) ?? .systemFont(ofSize: 30)

This took me 1 hour to figure out what is wrong in my code:(, since I'm using large title, it is hard to change the tintColor with largeTitle, why apple makes it so complicated, so many lines to just make a tintColor of navigationBar.

I am using a Picker View to allow the user to choose the colour theme for the entire app.

I am planning on changing the colour of the navigation bar, background and possibly the tab bar (if that is possible).

I've been researching how to do this but can't find any Swift examples. Could anyone please give me an example of the code I would need to use to change the navigation bar colour and navigation bar text colour?

The Picker View is set up, I'm just looking for the code to change the UI colours.

Changing navigation bar color in Swift

Swift

Xcode

我使用一个拾取器视图，以允许用户选择整个应用程序的颜色主题。我计划改变导航栏，背景和标签栏的颜色(如果可能的话)。我一直在研究如何做到这一点，但找不到任何Swift示例。谁能给我一个例子，我需要用来改变导航栏颜色和导航栏文本颜色的代码？Picker视图已设置，我只是寻找代码来改变用户界面的颜色。
