read and write CSV files in Swift 3 - swift

Question

I've seen different libraries like SwiftCSV, CSwiftV. AFAIK, they made for previous versions of swift. I need a very simple realization for swift 3 : open file, read line, put into array; or open, write array to csv file, and that's it. Any help?
I have:
struct Data {
var DataTime: Date = Date()
var Price: Double = 0.0
}
func DatafromCSV(_ CSV: String, _ separator: String) -> [Data] {
var x = [Data]()
//open file, read line, put into array, close file
return x
}
func DatatoCSV(_ CSV: String, _ separator: String) -> [Data] {
var x = [Data]()
//create file (erase data if exists, write data from array, close file
return x
}

Try to use CSVImporter Framework, is very simple. You can add it to your projects following this link: https://github.com/Flinesoft/CSVImporter
static func extractFromCSV(){
//the Path of the csv
let documentsUrl:URL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
let destinationFileUrl = documentsUrl.appendingPathComponent("name.csv")
let path = destinationFileUrl.path
let importer = CSVImporter<YourClassName?>(path: path,delimiter: ";")
importer.importRecords{ recordValues -> Sede_Azienda? in
//this piece of code is called for each row. You can access to each field with recordValues[x] and manage the data.
return nil //or the object if you need it
}
}
This is asynchronous but this framework has also some sync methods. Look the documentation.
NB: YourClassName is the type of class of the returned object if you need it.
