Importing JSON or CSV data to Firestore using Swift - ios

Question

It appears there is still no way to import JSON or CSV files directly to a Firestore database. Many of the suggestions are for JavaScript-based apps that do not translate well to Swift. Does anyone have a good Swift solution for adding data to a Firestore database using JSON/CSV?
//example json
[
{
"name": "Stone Cove Marina Inc",
"email": "NOT IN SAMPLE",
"category": "Docks",
"category2": "Marinas",
"category3": "Dock Builders",
"address": "134 Salt Pond Rd",
"city": "Wakefield",
"state": "RI",
"zip": 2879,
"phone": "[phone]",
"website": "http://stonecovemarinari.com"
},
{
"name": "Bluehaven Homes",
"email": "NOT IN SAMPLE",
"category": "General Contractors",
"category2": "Home Builders",
"category3": "",
"address": "5701 Time Sq",
"city": "Amarillo",
"state": "TX",
"zip": 79119,
"phone": "[phone]",
"website": "http://www.bluehavenhomes.com/"
}
]
//here is the database structure
//collection is "businesses"; each "business" gets a document id; within each document id set the data
database.collection("businesses").document().setData(/*data here*/)

You can try
let str = """
[
{
"name": "Stone Cove Marina Inc",
"email": "NOT IN SAMPLE",
"category": "Docks",
"category2": "Marinas",
"category3": "Dock Builders",
"address": "134 Salt Pond Rd",
"city": "Wakefield",
"state": "RI",
"zip": 2879,
"phone": "[phone]",
"website": "http://stonecovemarinari.com"
},
{
"name": "Bluehaven Homes",
"email": "NOT IN SAMPLE",
"category": "General Contractors",
"category2": "Home Builders",
"category3": "",
"address": "5701 Time Sq",
"city": "Amarillo",
"state": "TX",
"zip": 79119,
"phone": "[phone]",
"website": "http://www.bluehavenhomes.com/"
}
]
"""
do {
let json = try JSONSerialization.jsonObject(with:str.data(using:.utf8)!, options: []) as! [[String: Any]]
for var i in 0...json.count - 1
{
database.collection("businesses").document().setData(json[i])
}
} catch {
print(error)
}
