How to fix “Function declares an opaque return type, but has no return statements in its body from which to infer an underlying type”

Updated for Xcode 14.2

This error occurs for two reasons. First, you’ve created a view but didn’t actually return it from your view body, like this:

var body: some View {
    let name = "Paul"
    let message = Text("Hello, \(name)")
}

To make that compile, add return message:

var body: some View {
    let name = "Paul"
    let message = Text("Hello, \(name)")
    return message
}

The other common reason this happens is if you try to return two views without placing them in a container, like this:

var message: some View {
    Text("Hello")
    Text("World")
}

To fix this, place your views in a stack or a group, like this:

var message: some View {
    VStack {
        Text("Hello")
        Text("World")
    }
}
