I want to have an HTTP POST method, in swift for a MacOS app.

I’ve been trying to follow the instructions from here:
Connecting MySQL to IOS Applications

I’m stuck at this point.

I want a func to call, that does the work, and makes the data available.

 weak var delegate: Downloadable?
        
        
        let networkModel = Network()
        
        func downloaddailyoutlook(parameters: [String : Any], url: String) {
            
            let request = networkModel.request(parameters: parameters, url: url)
            
            networkModel.response(request: request) { (data) in
                let model = try! JSONDecoder().decode([dailyOutlook]?.self, from:data) as [dailyOutlook]?
                self.delegate?.didReceiveData(data: model! as [dailyOutlook])
                
            }
        }
    
    
    
    
    
}


extension DailyOutLookModel: Downloadable {
    
    let paramX = ["doy":  getDayOfYearX()]
    
    downloaddailyoutlook(parameters: paramX, url: URLServices.dailyoutlook)
    
    
        






func didReceiveData(data: Any) {
    DispatchQueue.main.sync {
        
    }
}
    
}
