How to parse an array of JSON from database in swift
How to parse an array of JSON from database in swift
In my app I'm trying to parse a JSON file.
This is my JSON:
[ { "locals": [{"name": "Mission Chinese Food", "localDescription": "A", "photograph": "img_02.jpg", "address": "171 E Broadway, New York, NY 10002", "timetable": "Lunedi al Sabato 08:00-12:00 e 14:00- 18:00 Domenica 08:00-12:00 e 14:00- 18:00", "numberOfReviews": 10, "numberInCity": 2, "cityName": "New York", "ratingValue": 5 }, { "locals": [{"name": "Mission Chinese Food", "localDescription": "A", "photograph": "img_02.jpg", "address": "171 E Broadway, New York, NY 10002", "timetable": "Lunedi al Sabato 08:00-12:00 e 14:00- 18:00 Domenica 08:00-12:00 e 14:00- 18:00", "numberOfReviews": 10, "numberInCity": 2, "cityName": "New York", "ratingValue": 5 }, ]
This is my swift file:
let url = URL(string: "https://www.litos.srl/showtime/dbGetLocal.php")
do {
let data = try Data(contentsOf: url!)
print(data[0])
guard let rootObject = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [[String:AnyObject]] else {
return locals
}
print(rootObject)
let localsObjects = rootObject[0]["locals"] as? [[String:AnyObject]]
} catch {
print(error)
return locals
}
return locals
}
This is the error that occurs in Xcode when I build and run the code:
60
Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.}

You data is invalid.It should not end with , before ] bracket.
Try this one. This will work if your JSON is valid.
For Example.
[ { "locals": [
{"name": "Mission Chinese Food", "localDescription": "A", "photograph": "img_02.jpg", "address": "171 E Broadway, New York, NY 10002", "timetable": "Lunedi al Sabato 08:00-12:00 e 14:00- 18:00 Domenica 08:00-12:00 e 14:00- 18:00", "numberOfReviews": "10", "numberInCity": "2", "cityName": "New York", "ratingValue": "5" }]}]
if let data = JSON as? NSArray {
for data in data {
if let data = data as? [String: AnyObject] {
if let data = data["locals"] as? NSArray {
for data in data {
if let data = data as? [String: AnyObject] {
}
}
}
}
}
}
Thank you for your answer, but this i the error that occur: Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.}

Your Url Response data is missing functionality please check, there is no proper end of dictionary.
Below is your Json response

The JSON is corrupted, there are 3 opening brackets
[but only 1 closing]and one extraneous comma as second last character.– vadian
