Hello Everyone,
I wanted to show full screen of UIViewController and using below code to present new controller. But when I am setting modalPresentationStyle as fullScreen then it’s crashing while dismiss() of view. Looking for solution any help will be appreciated. (Other style working fine problem with fullScreen)


*let* scannerViewController = ImageScannerController(delegate: *self*)
scannerViewController.modalPresentationStyle = .fullScreen

self.present(scannerViewController, animated: *true*)

// for dismiss
self.dismiss(animated: *true*, completion: *nil*) I am using kotlin multiplatform

self.dismiss will try to dismiss your current view (self), not the scannerViewController

@NicoLourenco I am using scannerview controller to dismiss

Is your delegate weak in ImageScannerController ?

[Akash]

public weak var imageScannerDelegate: ImageScannerControllerDelegate?

[Akash]

yes

                iosPlatformInterfaceImpl.viewController = mainViewController // Pass the reference to the view controller

I am using kotlin multiplatform this is the approach

issue resolved by using overFullScreen

[Akash]

seems fullscreen needs to use navigationview to push the screen then it'll work
