如何在 swiftui 中使用拖动手势缩放元素

Question

my example image

Here, in my example image you can see that I have a text "HELLO" and in the right corner having a button. I want that I can scale my text or element by Drag gesture of the right corner button. What is the efficient way?

Answer 1

• first, you need to add a Gesture to the scaling view so that when you drag it in the required way do action
• secondly, you need to add the height and width constraints to the viewController of the scaling view
• in last, you need to add a func that animates the width and height by increasing or decreasing the size depending on the gesture
