Why am I seeing 'Modifying state during view update'?

When you encounter the warning 'Modifying state during view update' in Swift, it usually indicates that your SwiftUI view is attempting to make changes to its state while it is in the process of rendering. This can lead to unpredictable behavior and is generally not recommended. To fix this, you should ensure that state changes are not made directly during the rendering phase of your view.
