By default, when you use:
|
||
|
|
|
||
|
|
```
|
||
|
|
controller.modalPresentationStyle = .popover
|
||
|
|
```
|
||
|
|
|
||
|
|
in a horizontally compact environment (iPhone in portrait mode), this option behaves the same as fullScreen.
|
||
|
|
You can make it to always show a popover by using:
|
||
|
|
|
||
|
|
```
|
||
|
|
let presentationController = AlwaysPresentAsPopover.configurePresentation(forController: controller)
|
||
|
|
```
