Advanced Pinch and Zoom features with SwiftUI gestures
The main learning topic of this short and engaging iOS project is to get familiar with almost every SwiftUI gesture, such as long-press gesture, double-tap gesture, drag gesture, and magnification gesture (a gesture that recognizes a magnification motion and tracks the amount of it). The only gesture that we will not cover in this tutorial is the rotation gesture.
We can apply a blur effect (with color vibrancy) to a view that appears behind another view by adding a material with the background modifier. The new SwiftUI material is not a view, but adding material is like inserting a translucent layer between the modified view and its background.
