`platform_id` parsing parameter error

[ByeongUkChoi]

https://github.com/liveview-native/live_view_native/blob/main/lib/live_view_native/live_session.ex#L46

as shown above liveview-native can find the platform_id when the app requests

GET /?_platform=swiftui

However, my app requests as follows

GET /?_lvn_platform=swiftui

I just installed it with this command

mix lvn.install

It's probably because it's spent here. https://github.com/liveview-native/liveview-client-swiftui/blob/main/Sources/LiveViewNative/Coordinators/LiveSessionCoordinator.swift#L222

So what do you think about adding this function to the LiveViewNative.LiveSession module as a buffer code?

defp get_platform_context(%{"_lvn_platform" => platform_id} = connect_params) do
  connect_params
  |> Map.put_new("_platform", platform_id)
  |> get_platform_context()
end

@ByeongUkChoi These proposed changes have already been implemented in the next branch of this repo. This is happening because of a version mismatch between live_view_native and liveview-client-swiftui within your project:

• If your Xcode project uses the main branch of liveview-client-swiftui, you're using bleeding edge changes of the SwiftUI LVN client. In that case, you should use the next branch of this repo in your Elixir app which includes the changes you describe in this issue (merged in https://github.com/liveview-native/live_view_native/pull/60). In your mix.exs:

# Specifies your project dependencies.
#
# Type `mix help deps` for examples and options.
deps do
  [
    # ...
    {:live_view_native, git: "https://github.com/liveview-native/live_view_native", branch: "next"},
    {:live_view_native_swift_ui, git: "https://github.com/liveview-native/liveview-client-swiftui", branch: "main"}
    # ...
  ]
end

• If you'd rather use a versioned release of live_view_native in your Elixir app (like 0.1), you'll need to also use a tagged release of liveview-client-swiftui (like 0.1.2) instead of main. In your Xcode project:

Oh just one more thing to note; the next branch of this repo is currently incompatible with the liveview-client-swiftui unless you're using this branch - https://github.com/liveview-native/liveview-client-swiftui/pull/1154. Using a non bleeding-edge / versioned release for both dependencies avoids this.

@supernintendo Hi~ Sources/LiveViewNative/Coordinators/LiveSessionCoordinators.swift In this file, you are sending the platform value with the key _lvn_platform. However, there is still no part of https://github.com/liveview-native/live_view_native/tree/next or https://github.com/liveview-native/liveview-client-swiftui/pull/1154 parsing the _lvn_platform.

[ByeongUkChoi]

@supernintendo Oh Now It works. It changed from :platform to :format

  def render(%{format: :swiftui} = assigns) do
    ~SWIFTUI"""
    <VStack>
      <Text>
        Hello native!
      </Text>
    </VStack>
    """swiftui
  end

@ByeongUkChoi Oh right, I forgot to mention that as well. There are a number of breaking changes in the next branch that we'll document with the actual release of 0.2; right now a few things are in flux and subject to change. Thank you for your patience as we get the next version ready to publish 🙂

Also, that _lvn_platform param actually seems to be dead code in the Swift client but I'll look into it a bit more to confirm. The actual connection params have been moved to a map called _lvn; the relevant code for that on both ends is here:
