My sample app has been working with the following code:


   func call(arguments: Arguments) async throws -> ToolOutput {
        var temp:Int
        
        switch arguments.city {
            case .singapore: temp = Int.random(in: 30..<40)
            case .china: temp = Int.random(in: 10..<30)
        }
        
        let content = GeneratedContent(temp)
        let output = ToolOutput(content)
        return output
    }

However in 26 beta 5, ToolOutput no longer available, please advice what has changed.

That's correct! We deprecated ToolOutput in beta 5, and replaced it with either String or GeneratedContent tool output.

I found that I can change to:

func call(arguments: Arguments) async throws -> GeneratedContent {
        var temp:Int
        
        switch arguments.city {
            case .singapore: temp = Int.random(in: 30..<40)
            case .china: temp = Int.random(in: 10..<30)
        }
        
        return GeneratedContent(temp)
    }

But not sure if this is correct.

Will the Landmarks example project from WWDC 25 be updated? It makes use of ToolOutput and thus doesn't work anymore ootb.
