So I've found that the you cannot open URLs (and therefore deeplinks) from Share Extensions in iOS. But I'm wondering if there is any way to open the container app of the extension.
For instance, in my app the share extension will only work if you are logged in, so if you tap the extension it will present an alert view telling you so. But I want a button on that alert view to bring you into the container app to make it easier to log in.
Hope this makes sense and thanks in advance!
