JSON parsing swift 3 - json

Question

if statusCode == 200 {
let json = response.result.value as? NSDictionary
print("JSON FILE")
//print(json)
let companies = json?["companies"] as? [AnyObject]
print(companies)
for value in companies! {
let address = value["address"] as? String
print(address)
let schedule = companies?["schedule"] as? [AnyObject]// as? NSDictionary
print(schedule)
for sch in schedule! {
}
}
}
Here json file
{
"code": "200",
"message": "OK",
"companies": [
{
"id": "1",
"img": "doxsun.jpg",
"schedule": [
{
"id": "1",
"company_id": "1",
"day": "0",
"time_from": "06:00:00",
"time_to": "23:00:00"
}
]
},
{
"id": "2",
"img": "zalypa.jpg",
"schedule": []
}
]
}
I have a problem with json file parsing how correctly parse it? I can't parse schedule. How to convert all this types? words to pass quality. words to pass quality.words to pass quality.words to pass quality.words to pass quality.words to pass quality.words to pass quality.words to pass quality.words to pass quality.words to pass quality.

Answer 1

There are some conversion issues with correct types using as operator. I believe the below code should allow you to iterate through schedules of each company:
if let JSON = response.result.value as? [String: AnyObject] {
if let companies = JSON["companies"] as? [[String: AnyObject]] {
for company in companies {
if let schedules = company["schedule"] as? [[String: AnyObject]] {
for schedule in schedules {
// do something with the schedule
}
}
}
}
}
