[iOS] Picker not displayed when not on main view controller

[dan15d]

Retrieve the top view controller from the view hierarchy and display picker.

In the current versión i get this error:

Attempt to present <UIDocumentPickerViewController: 0x10c80ac00> on <.MainViewController: 0x10a0099f0> (from <.MainViewController: 0x10a0099f0>) whose view is not in the window hierarchy.

Thanks for reporting that!
What about using LocalUIViewController.current is it going to fix the issue?

[dan15d]

Unfortunately, LocalUIViewController.current requires a @composable context and the onLaunch callback of FilePickerLauncher doesn't have this context.

[MohamedRejeb]

Yes that's ok, it can be created on Compose:
val uiViewController = LocalUIViewController.current
and then passed to onLaunch, also it should be passed as a key to the remember

[dan15d]

That works! Do you want me to upload the changes?

[MohamedRejeb]

Yes

[MohamedRejeb]

It need to be added as a key to the remember as well:

...
    return remember(currentUiViewController) {
        FilePickerLauncher(
...

[MohamedRejeb]

Also, you forgot to push the import for LocalUIViewController I guess

[dan15d]

yes, i fix it. sorry

[MohamedRejeb]
