so I try to sort data from with most likes to the least. How do I do that if don't have an object name? because currently I only have the ID of the object?
here's my Firebase json:
["-KfSODzRPjy46ayCFRBH": {
"_createdAt" = 1489773065234;
"_updatedAt" = 1489773065234;
content = (
"<null>",
Tittle,
"why not there is the nnnd ksksks lalalalalkdkdkdkdk kadsjfakl;",
whhhhhhalalallala
);
imageTitle = 1489773064177;
like = 2;
title = "Third Post";
},
["-KfSODzRPjy46ayCFRBH": {
"_createdAt" = 1489773065234;
"_updatedAt" = 1489773065234;
content = (
"<null>",
Tittle,
"why not there is the nnnd ksksks lalalalalkdkdkdkdk kadsjfakl;",
whhhhhhalalallala
);
imageTitle = 1489773064177;
like = 3;
title = "Third Post";
},
this is how I read:
let handleref = databaseRef.child("v1/postmodel").observe(.value, with: { (snapshot) in
let postDict = snapshot.value as! [String : AnyObject]
print(postDict)
})

This is the JSON object I'm getting from the openweathermap - API:
["main": {
humidity = 12;
pressure = 922;
temp = "271.13";
"temp_max" = "171.15";
"temp_min" = "291.15";
}, "name": mycity, "id": 299129219, "coord": {
lat = "92.1211";
lon = "182.1211";
}, "weather": <__NSArrayI 0x1c042e820>(
{
description = "light snow";
icon = 13n;
id = 120;
main = Snow;
},
{
description = mist;
icon = 50n;
id = 722;
main = Mist;
}
)
, "clouds": {
all = 12;
}, "dt": 211, "base": stations, "sys": {
country = XXX;
id = 4891;
message = "0.02221";
sunrise = 1221122112;
sunset = 4343344343;
type = 1;
}, "cod": 100, "visibility": 3200, "wind": {
speed = 3;
}]
Because I like to readout some information (like the current temperature, the weather description, etc.) I tried to use this few lines:
let temperature = (result["main"] as! [String:Double])["temp"]!
The code above is working fine but I got massive problems reading out the description of the first Weather element (called "light snow"):
let description = (result["weather"] as! [String:Any]).first["description"]! //(result should be : "light snow")
... doesn't seems working at all.
So how can I fix this issue?
Thanks a million in advance.
Also used this API :)
This worked for me:
guard let weathersArray = json["weather"] as? [[String: Any]],
let weatherJson = weathersArray.first,
let description = weatherJson["description"] as? String
else { return }
Update: in case you want all the array elements just loop over the weathersArray and get all the descriptions.
This question already has answers here:
type 'Any' has no subscript members

Closed 5 years ago.
i know to much ask like this. i already searching but not match with my problems.
oke i will try explain with my code
i have data API Like this

i already can got fullName, Addres, Skill State etc
if let profile = json["profile"] as? NSDictionary {

but i don't know how to get atribut in totalConversation like question, storeItems, points

totalConversations = {

};
i tried like
let profile = json["profile"]["totalConversation"] as? NSDictionary
error sign : Type 'any?' has no subscript members
You got that error because json["profile"] is Any type and it doesn't have any subscript. So you need to cast json["profile"] to a dictionary, [String: Any] is dictionary type in Swift.
if let profile = json["profile"] as? [String: Any] {
if let totalConversations = profile["totalConversations"] as? [String: Any] {
let questions = totalConversations["questions"] as? Int
}
}
Let's say, there is shipping nsdictionary value is required to send to server, and there is items NSMutableArray inside shipping and, again there is sub-items NSMutableArray inside items.
That's why I've coded like that:
for cake in cakes {
for item in cakeItemsOpt {
let optionalItem = [
"item_req_mod_p_id": item.cakeItemModId,
"l_req_mod_p_id": item.cakeModId,
"mod_id": item.cakeModId,
"mod_qty": item.cakeQty
]
itemsOptional.add(optionalItem)
}
for item in cakeItemsReq {
let requiredItem = [
"item_req_mod_p_id": item.cakeItemModId,
"l_req_mod_p_id": item.cakeModId,
"mod_id": item.cakeModId,
"mod_qty": "1"
]
itemsRequired.add(requiredItem)
}
let cakeParam: NSDictionary = [
"id": cake.cakeId,
"qty": cake.cakeQty,
"type": cake.cakeType,
"name": cake.cakeName,
"image": cake.cakeImage,
"req_modifiers": itemsRequired,
"opt_modifiers": itemsOptional
]
items.add(cakeParam)
}
let param: NSDictionary = [
"user_id": user_id,
"token": token,
"delivery": "del",
"delivery_remark": delivery_remark,
"delivery_date": delivery_date,
"delivery_time": delivery_time,
"delivery_charge": delivery_charge,
"item": items,
"payment_method_id": payment_id,
] as [String : Any]
param is main object to send to server.
But the result is not what I've expected,
["delivery_remark": "heavy", "payment_method_id": "4", "delivery": "del", "token": "0l8BwedwkZQltcFYFhCpicQZeQOhikyYLxa8R3u2", "item": <__NSArrayM 0x60800044ea90>(

There is <__NSArrayM 0x60800044ea90> included in my object. Please let me know how to correct my coding to get correct result. Thanks.
Then i guess you want something like
let data: [String : [String : [String : [String]]]]
data = [
"shipping" : ["items" : ["subitemKey" : ["subitemArray"]]]
]
So you have a dictionary that contains a dictionary for a key "shipping" that contains a dictionary for key "items" that contains arrays for keys of different subitems
I'm building an iOS app in Swift 3 and I'm using Google Places API to get places data. I'm using the iOS API to get most of the data I need. But I also need to get the opening times which aren't (yet) provided by the iOS API.
So I have to query the web API to get that information. The request side of things is working fine, however, once I get the result and I turn it into JSON with JSONSerialisationand then print the output in the console, the format of this JSON is strange and I'm struggling to parse it.
When I paste that into a JSON reader it says it's invalid.
Here is the JSON that looks strange to me with these "(" and "=":

Their matcha green tea is nice as well.\n\nThe only problem is that there is never enough seating during peak hours and it gets claustrophobic when it's crowded with people doing their homework.\n\nSeats are also cheap and hurt your butt.\n\nThis place usually attracts the Asian crowd.";

And here is my code with a dummy query:

let urlRequest = URLRequest(url: url!)

(data, response, error) in
guard error == nil else {
print(error!)
return

guard let responseData = data else {
print("Error: did not receive data")
return
}
do {
guard let placeData = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.allowFragments)
as? [String: Any] else {
print("error trying to convert data to JSON")
return
}
print("The placeData is: \(placeData.description)")
guard let website = placeData["website"] as? String else {
print("Could not get the website from JSON")
return
}
print("The title is: \(website)")
} catch {
print("error trying to convert data to JSON")
return
}
}
task.resume()
Any help understanding what's going on would be much appreciated. The final objective is to get the Opening hours a Dictionary with the keys being the days of the week and the values being the opening times.
Thanks in advance
The problem is that reponseData is a dictionary with a key response containing the actual dictionary you want. The JSON looks something like:
{
"result": {
"website": "example.com"
}
}
So the correct code would be:
let url = URL(string: "https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJheCrEY6AhYARxCkT8_KjDWE&key=[MYAPIKEY]")
let urlRequest = URLRequest(url: url!)
let task = URLSession.shared.dataTask(with: urlRequest) {
(data, response, error) in
guard error == nil else {
print(error!)
return
}
guard let responseData = data else {
print("Error: did not receive data")
return
}
do {
guard let placeData = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.allowFragments)
as? [String: Any] else {
print("error trying to convert data to JSON")
return
}
print("The placeData is: \(placeData.description)")
guard let website = (placeData["result"] as? [String : Any])?["website"] as? String else {
print("Could not get the website from JSON")
return
}
print("The title is: \(website)")
} catch {
print("error trying to convert data to JSON")
return
}
}
task.resume()
I simply changed:
guard let website = placeData["website"] as? String else {
to:
guard let website = (placeData["result"] as? [String : Any])?["website"] as? String else {
I am using Swift with Firebase as my backend. For some reason, I am getting this error in one of my snapshots:
Could not cast value of type '__NSArrayM' (0x10591cc30) to 'NSDictionary'
I get this when I use this code:
let snapVal = snapshot.value as! [String: AnyObject]
Why is this happening to just this data snapshot, when it looks like all the other data snapshots?
The data looks like this:
Snap (PERSON) {
1 = {
DESCRIPTION = "Brief description here..";
"DOB" = "10/15/92, 8:29 PM";
"STATUS" = 1;
SONG = "A song";
"START_DATE" = "10/05/16, 7:59 PM";
};
}
The snapVal looks like this (when I do not specify it as [String: AnyObject]:
(
"<null>",
DESCRIPTION = "Brief description here..";
"DOB" = "10/15/92, 8:29 PM";
"STATUS" = 1;
SONG = "A song";
"START_DATE" = "10/05/16, 7:59 PM";
}
)
Why is this the case?
Make sure that the data that you are retrieving is of type NSDictionary
Then Try changing :-
let snapVal = snapshot.value as! [String: AnyObject]
To :-
if let snapVal = snapshot.value as? [String: AnyObject]{
print(snapVal)
}
I had the same problem and I fixed it by changing the child value from 0, 1, 2 etc to string values such as p0, p1 which solved my problem. Firebase doesn't actually save a title value for that child when you only use Int's. If that makes sense.
So change the 1 to something like "value1" or "v1" and use swift to reorganise the array with array.sort { $1.status > $0.status }
Snap (PERSON) {
1 = {
DESCRIPTION = "Brief description here..";
"DOB" = "10/15/92, 8:29 PM";
"STATUS" = 1;
SONG = "A song";
"START_DATE" = "10/05/16, 7:59 PM";
};
}
to:
Snap (PERSON) {
"value1" = {
DESCRIPTION = "Brief description here..";
"DOB" = "10/15/92, 8:29 PM";
"STATUS" = 1;
SONG = "A song";
"START_DATE" = "10/05/16, 7:59 PM";
};
}
