Depend on vscode-swift

[MahdiBM]

I don't have a lot of information about VSCode extensions, and how they can work with a iOS project, but it looks to me this extension should depend on the official https://github.com/swiftlang/vscode-swift extension which doesn't support iOS projects, then add iOS project support itself?

I'm not sure if https://github.com/swiftlang/vscode-swift can easily add "official" iOS project support, so I'm fine with the iOS project support to remain in this extension, at least for now.

Right now it appears there is a lot of duplicate work being done by the 2 extensions.

The Swift team has allocated a few people for projects like https://github.com/swiftlang/vscode-swift and they seem to be consistently very active on maintaining that project. They also welcome contributions if you need to change something in that extension so it can work with this extension in a better way, though you'd of course need good reasons for them to accept the changes.

Or you can contact them and mention how this extension works and what you'll need, and see what you guys can figure out for iOS project support for Swift in a VSCode extension.
