What is the difference between a push segue and a modal segue?

A push segue and a modal segue are both types of transitions used in iOS development to navigate between view controllers.

The main difference between a push segue and a modal segue lies in the way the new view controller is presented.

- Push Segue: A push segue is used to navigate within a navigation controller hierarchy. It is typically used when there is a navigation bar present in the source view controller. When a push segue is triggered, the new view controller is pushed onto the navigation stack, and the navigation bar automatically provides a back button to navigate back to the previous view controller.

- Modal Segue: A modal segue is used to present a view controller modally, overlaying the current view controller. It is typically used when there is a need to temporarily interrupt the current workflow or display a separate task. When a modal segue is triggered, the new view controller is presented modally, covering the entire screen. It usually requires the user to dismiss the presented view controller to return to the previous view controller.

In summary, a push segue is used for hierarchical navigation within a navigation controller, while a modal segue is used for presenting a view controller modally on top of the current view controller.
