Import or use csv data.

Fist of all, I am new in developing.

I want to use data from CSV files to process and use for calculation. I tried to use TabularData, but I don't know how and where to write to import or use the csv data. My file name is fnudos.csv.

import Foundation
import TabularData

Data = "fnudos.csv"

let nudos = try DataFrame(contentsOfCSVFile: policiesURL, rows: 0..<100)

print(nudos)

Something like that? But I don't have results.

Thanks in advance for your answers.
