Solved: change navigation bar color

An important aspect of iOS application development is to shape user interface design to not only be aesthetically pleasing, but also intuitive and user-friendly. One subtle but significant aspect of many applications is the navigation bar, commonly seen at the top of an app’s screen. Developers using Swift—a powerful and intuitive language for macOS, iOS, watchOS, and tvOS app development—often look to personalize and align the navigation bar color with their app’s overall theme and design.

Swift offers several ways to change the navigation bar color, with the primary method involving UIKit, a framework that provides a set of reusable UI elements. By altering the properties of these elements, developers can customize aspects such as color, translucency, and effects.

Setting the Navigation Bar Color

The solution to changing the navigation bar color in Swift involves the `UINavigationBar` class. The `UINavigationBar` class is a part of UIKit and represents the navigation bar in an app. It encompasses several properties that allow its customization, including `barTintColor`, which directly changes the background color of the navigation bar.

let navigationBarAppearace = UINavigationBar.appearance()
navigationBarAppearace.barTintColor =

Step-by-step Explanation

Begin customizing the navigation bar by accessing the appearance proxy for the `UINavigationBar` class, using `UINavigationBar.appearance()`.

let navigationBarAppearace = UINavigationBar.appearance()

Next, set the `barTintColor` property of `UINavigationBar` to UIColor of your choice. For example, if you want the navigation bar to be red, the respective code will look like this:

navigationBarAppearace.barTintColor =

However, changing the navigation bar color alone can often clash with the default color of the buttons, title, etc. Changing the `tintColor` property affects the color of buttons and zingers.

navigationBarAppearace.tintColor = UIColor.white

Lastly, text color can be changed using `titleTextAttributes`:

navigationBarAppearace.titleTextAttributes = [NSAttributedString.Key.foregroundColor:UIColor.white]

Additional Libraries and Functions

Aside from UIKit and built-in functions, there are libraries like Chameleon Framework that offer features for color manipulation and schemes. The Chameleon Framework enables developers to create colorful, stunning apps effortlessly.

For problems similar to this, libraries like SnapKit can help design user interfaces to look great on all screen sizes. SnapKit is a DSL to make Auto Layout easy on both iOS and OS X.

The range of styles, looks, and trends in application development resemble the diversity in the fashion world. Knowing how to manipulate basic elements like navigation bar colors to achieve your unique vision can set your app apart. Remember, just like in fashion, trends in UI/UX design change frequently. Always keep up with current trends to deliver what users expect.
