CSV File Load Into Swift

Hi, I am fairly new Xcode/Swift and am trying to load a CSV File for use in my development. I have placed the CSV file in my Assets folder but when I try to create my Data Model and load the CSV file. I run into the error: No exact matches in call to initializer. Below is the code. I have attached CSV File. Any help fixing this error would be greatly appreciated. Thanks in advance for your help.

import Foundation

import CSV

struct HospitalData: Codable { let providerNumber: String let hospital: String let address: String let city: String let state: String let zip: String let wageIndex: Double let caseMix: Double let averageCharge: Double let discharges: Int let totalCharges: Double let adjTotalCharges: Double // Add other fields as needed based on the columns in your CSV file }

func loadHospitalData() -> [HospitalData]? { guard let filePath = Bundle.main.path(forResource: "Hospital_Demographic_Data", ofType: "csv") else { print("File not found") return nil }

do {
    let csv = try CSV(url: URL(fileURLWithPath: filePath))
    var hospitalDataList = [HospitalData]() // Initialize as an empty array
    
    for row in csv.namedRows {
        if let providerNumber = String(row["Provider CCN"] ?? ""), // Replace "Provider CCN" with actual column name
           let hospital = String(row["Hospital Name"] ?? ""), // Replace with actual column name
           let address = String(row["Street Address"] ?? ""),
           let city = String(row["City"] ?? ""), // Replace with actual column name
           let state = String(row["State Code"] ?? ""), // Replace with actual column name
           let zip = String(row["Zip Code"] ?? ""), // Replace with actual column name
           let wageIndex = Double(row["Wage Index"] ?? ""),
           let caseMix = Double(row["Case Max"] ?? ""),
           let averageCharge = Double(row["Base Charge"] ?? ""), // Replace with actual column name
           let discharges = Int(row["Medicare Discharges"] ?? ""),
           let totalCharges = Double(row["Total Charges"] ?? ""),
           let adjTotalCharges = Double(row["Total Wage Normalized Charges"] ?? "") { // Replace with actual column name
            let hospitalData = HospitalData(
                providerNumber: providerNumber,
                hospital: hospital,
                address: address,
                city: city,
                state: state,
                zip: zip,
                wageIndex: wageIndex,
                caseMix: caseMix,
                averageCharge: averageCharge,
                discharges: discharges,
                totalCharges: totalCharges,
                adjTotalCharges: adjTotalCharges
            )
            hospitalDataList.append(hospitalData)
        }
    }
    return hospitalDataList
} catch {
    print("Failed to load CSV file: \(error)")
    return nil
}

}

// Usage Example func main() { if let hospitalData = loadHospitalData() { for data in hospitalData { print("Hospital: (data.hospital), City: (data.city), Average Charge: (data.averageCharge)") } } }
