I would like to dry up a function for loading json arrays and Decodable models with one function, I am trying to pass an array pointer to the function to set the array within via a JSONDecoder.decode

the error I get is
error Cannot convert value of type '[T.Type]' to expected argument type 'T.Type'

I saw the thread Passing Decodable Object.Type as generic parameter
And perhaps its the solution, I used the part
where T : Decodable
from the thread but don't know enough beyond this. First app fully using Swift I haz no idea what im doing beyond trying to apply other languages GameDesign logic to Swift


func loadJSONAsEvent<T>(_ urlString: String, dataArrayEvents: inout [T.Type]) where T : Decodable {
    
    guard let url = URL(string: urlString) else {
        print("missing urrllll")
        return
    }
    
    let session = URLSession.shared
    let task = session.dataTask(with: url){(data,response, error) in
        if(error == nil && data != nil){
            let decoder = JSONDecoder()
            do {
                // this works
                //let gg = try decoder.decode(SUBPLOTDATA.AllJSONEvents, from: data!)
                
                // need to get this to work
                // error Cannot convert value of type '[T.Type]' to expected argument type 'T.Type'
                let ww = try decoder.decode(dataArrayEvents, from: data!)
                
                //print(gg[2].featuredImage?.url as Any)
                
                DispatchQueue.main.async {
                    SUPERAPP.shared.hasLoadedJSON = true
                }
                
            } catch {
                //print("JSON error: \(error.localizedDescription)")
                print(String(describing: error))
            }
        }
    }
    task.resume()
}

Neat! thank you, that got the error out but it opened up other issues. Im not even sure I should be trying to do it this way. Since the new issues are a whole nother issue ill make a new post
