xcode present modally code example

Example: segue types swift 5

1. Show - Pushes the destination view controller onto the navigation stack, 
moving the source view controller out of the way
(destination slides overtop from right to left),
providing a back button to navigate back to the source - on all devices.

Example: Navigating inboxes/folders in Mail.

2. Show Detail - Replaces the detail/secondary view controller when in a 
UISplitViewController with no ability to navigate back to the 
previous view controller.

Example: In Mail on iPad in landscape, 
tapping an email in the sidebar replaces the view controller on the right
to show the new email.

3. Present Modally - Presents a view controller in various different ways
as defined by the Presentation option, 
covering up the previous view controller -
most commonly used to present a view controller that animates up from the bottom
and covers the entire screen on iPhone,
but on iPad it's common to present it in a centered box format overtop that darkens the underlying view controller.

Example: Tapping the + button in Calendar on iPhone.

4. Popover Presentation - When run on iPad,
the destination appears in a small popover,
and tapping anywhere outside of this popover will dismiss it. On iPhone,
popovers are supported as well but by default if 
it performs a Popover Presentation segue, 
it will present the destination view controller modally over the full screen.

Example: Tapping the + button in Calendar on iPad 
(or iPhone, realizing it is converted to a full screen presentation as opposed to an actual popover).

5. Custom - You may implement your own custom segue and have complete control over its appearance and transition.
