Cast button does not appear on iOS

[sebj54]

When you run iOS demo or your own project with this plugin as a dependency, the cast button does not appear.

Here is the code I used in my app:

<action-bar title="My demo app">
    <action-item ios.position="right">
        <stack-layout 
            orientation="horizontal" 
            backgroundColor="red"
        >
            <cast-button
                @cast="handleCastEvent"
                color="#ffffff"
                backgroundColor="green"
            />
        </stack-layout>
    </action-item>
</action-bar>

And here is what happens in the app (see the red background-color where the cast button should appear):

In the demo, here is what happens:

Run demo app

cd demo
ns debug ios

Do you have any idea on how I can debug this issue?

I'm guessing this is for iOS 15 only? Apple seem to always add a new requirement for each version, although I don't see any iOS 15 specifics listed here: https://developers.google.com/cast/docs/ios_sender/

I don't know if it's iOS 15 specific. I'll try soon to compile on a iOS 14 device if it can add extra info to this issue.

There were errors preventing the first compilation (see #42), I guess they are specific to iOS 15.

By the way, I never saw this dialog:

Maybe I can add logs somewhere to see if there is any error? As I don't know iOS that much, do you know where I can start?

I just figured out why I did not see this modal… I was not connected to a wifi network 🤦
