How to remove app shadow in iOS 16

Using Custom UIViewRepresentables

One of the easiest ways to remove app shadow in iOS 16 is by using custom UIViewRepresentable classes. This technique involves creating a new class that extends UIViewRepresentable, which allows you to define your own view hierarchy and customize its appearance. By doing this, you can completely remove app shadow from your UI elements and create a more streamlined design.
Here’s an example of how you might use custom UIViewRepresentable to remove app shadow from a button:
swift

struct ShadowlessButton: UIViewRepresentable {

var title: String

func makeUIView(context: Context) -> UIButton {

let button UIButton()

    button.setTitle(title, for: .normal)

button.backgroundColor .white

    // Remove app shadow from button

button.layer.shadowOpacity 0

button.layer.shadowOffset CGSize.zero

    button.layer.shadowColor  UIColor.clear.cgColor

return button

}

func updateUIView(_ uiView: UIButton, context: Context) {}

}

In this example, we’re using ShadowlessButton to create a custom button with no app shadow. We achieve this by setting the button’s shadowOpacity, shadowOffset, and shadowColor properties to zero or clear, respectively. This effectively removes any app shadow that might have been applied to the button.

Using UIKit’s Built-in Shadow Removal Techniques

In addition to using custom UIViewRepresentable classes, there are a number of built-in shadow removal techniques available in iOS Kit. These techniques allow you to remove app shadow from your UI elements without having to write any custom code.
One such technique is shadowColor, which allows you to change the color of the shadow applied to a view. By setting this property to clear, you can effectively remove app shadow from a view:
swift
let button UIButton()
button.setTitle("Click Me", for: .normal)
button.backgroundColor .white
button.layer.shadowColor UIColor.clear.cgColor
button.layer.shadowOpacity 0
button.layer.shadowOffset CGSize.zero

Another technique is shadowRadius, which allows you to adjust the size of the shadow applied to a view. By setting this property to zero, you can effectively remove app shadow from a view:
swift
let button UIButton()
button.setTitle("Click Me", for: .normal)
button.backgroundColor .white
button.layer.shadowRadius 0
button.layer.shadowOpacity 0
button.layer.shadowOffset CGSize.zero

Using Automatic Layout and Adaptive Interface Designs

In some cases, removing app shadow from your UI elements may not be as simple as changing a single property or using custom code. In these situations, you may need to consider using automatic layout and adaptive interface designs to create a cleaner, more minimalistic interface that works well on all devices.
Automatic layout allows you to design interfaces that automatically adjust their size and position based on the device they are running on. This can help you create interfaces that are optimized for both small and large screens, without sacrificing performance or usability.
Adaptive interface designs take this a step further by allowing you to create interfaces that are tailored to specific devices or user preferences. By using adaptive design techniques, you can create interfaces that are more intuitive and easier to use, while still maintaining a consistent look and feel across all devices.

Facebook Messenger is one of the most popular messaging apps on both iOS and Android platforms. In recent years, Facebook has made a number of changes to its app design to improve performance and usability, including removing app shadow from many of its UI elements. Here’s an example of how Facebook might remove app shadow from a button using custom UIViewRepresentable:
swift
struct ButtonWithShadowlessView: UIViewRepresentable {
var title: String

func makeUIView(context: Context) -> UIButton {
    let button = UIButton()
    button.setTitle(title, for: .normal)
    button.backgroundColor = .white

    // Remove app shadow from button
    button.layer.shadowOpacity = 0
    button.layer.shadowOffset = CGSize.zero
    button.layer.shadowColor = UIColor.clear.cgColor

    return button
}

func updateUIView(_ uiView: UIButton, context: Context) {}

}

Google Maps is another popular iOS app that has made some significant changes to its design in recent years. One of the key features of these changes is the removal of app shadow from many of its UI elements, which helps to create a more streamlined and intuitive interface. Here’s an example of how Google might remove app shadow from a button using shadowColor:
swift
let button = UIButton()
button.setTitle("Get Directions", for: .normal)
button.backgroundColor = .white
button.layer.shadowColor = UIColor.clear.cgColor
button.layer.shadowOpacity = 0
button.layer.shadowOffset = CGSize.zero
