Changing the color of icons: A step-by-step guide

To change the color of an icon on iOS 18, you will need to use the UIImage class and its withRenderingMode() method. This method allows you to specify how the image should be rendered, including whether it should be tinted or not. Here’s an example of how to do this:
swift

let iconImage UIImage(named: “icon”)!

let tintedIconImage iconImage.withRenderingMode(.alwaysTemplate)

In the above code, we first create a UIImage object called iconImage and assign it the name of our icon file. We then call the withRenderingMode() method on this image and pass in .alwaysTemplate. This will render the icon as a template image, which can be tinted using the UIColor class.

Tinting the icon: A few things to keep in mind

When tinting an icon, there are a few things you should keep in mind to ensure that it looks good and is easy to use. First, you should make sure that the icon has enough contrast with its background so that it stands out clearly. This can be achieved by using a high-contrast color for the icon or by adjusting the brightness and contrast of the background image.
Another important consideration is the size of the icon. If the icon is too small, it may not be easily recognizable to users. On the other hand, if it is too large, it may take up too much space in the user interface. To avoid these issues, you should make sure that your icons are sized appropriately for their intended use and that they are easily distinguishable from other elements on the screen.

Real-life examples of icon color changes

There are many examples of apps that have successfully altered the color of their icons to improve their user experience. One such example is the popular social media app Instagram, which changed its icon color from orange to black in 2018. This change was part of a larger redesign of the app’s interface and helped to make it look more modern and sleek.
Another example is the messaging app WhatsApp, which updated its icon to a simpler, more recognizable design in 2016. The new icon, which features a stylized version of the app’s name in white text on a blue background, was designed to be more easily identifiable and memorable to users.
