Now im trynt to consume via API...

VIEWMODEL

 // BUSCA DADOS DE UMA API
    func buscaAPI() {
        // fetch json, decode, e update property array
        guard let url = URL(string: apiUrl) else { return }
        URLSession.shared.dataTask(with: url) { (data, resp, err) in
            // check error

            DispatchQueue.main.sync {
                self.listagemProdutos = try! JSONDecoder().decode([Produtos].self, from: data!)
            }

        }.resume()
    }

struct Produtos : Identifiable, Decodable{
    var id = UUID()
    var produto : String
    var descricao : String
    var imagem : String
    var preco : Double
    var destaque : Bool
    var categoria : String
    var ordenacao : Int

    enum CodingKeys: String, CodingKey {
        case produto, descricao, imagem, preco, destaque, categoria, ordenacao
    } 

}

but data dont appers....

please help me, no data shows in I acess via api, but when local its work normal.

So there are two things you can do here to debug. The first is to print out the error you are probably receiving in the closure ( where you say // check error). Print everything you get out, data, resp, and error.

The other is to just run the debugger.

Paul rarely shows the debugger but that I think i because he needs to build and run code in a short time.

Looking at that code though it looks like it would in fact crash on missing data, is that what you are seeing?

edit:

Actually its possible that your apiURLStr is missing, it is good practice to pass in those values into the method rather than depend on an instance variable.
