Json Array - Blackberry - blackberry

I try to get data from json array
String username = object.getJSONObject("items").getString("f");
But it gives me a error
"items.f" not found.
Below is the Json Array.
{
"items": [
{
"s": "0",
"f": "monems",
"m": "ustad"
},
{
"s": "0",
"f": "monems",
"m": "There?"
},
{
"s": "0",
"f": "monems",
"m": "What's going on ?"
},
{
"s": "2",
"f": "monems",
"m": "Sent at 4:03AM May 20th"
}
]
}


try this -
JSONArray items=object.getJSONArray("items");
for(int i=1;i<=items.length();i++){
JSONObject jsonObj=items.getJSONObject(i);
String s=jsonObj.getString("f");
}

Schema definition in Swagger

I'm very new to OpenAPI and I'm using http://editor.swagger.io to design an API.
I'm stuck in Schema with a JSON looking like following
{
"CORRELATION_ID": "10",
"CONTROL":
{
"DAS_IS_RECIPIENT": "123",
"DOCTPYE": "ert",
"PROCESS_INDICATOR": "nord"
},
"HEADER":

"DMS_DOC_ID": "876",
"INVOICE_DATE": "10082020"
},
"ITEMS": [
{
"SHORT_TEXT": "123",
"LSTAR": 0,
"QUANTITY": "23"
},
{
"SHORT_TEXT": "456",
"LSTAR": 234,
"QUANTITY": "21"
}
],
"DEBITOR":
{
"ID": "444",
"FIRSTNAME": "nick",
"LASTNAME": "cantre"
},
"CREDITOR":
{
"ID": "454",
"FIRSTNAME": "ava",
"LASTNAME": "pierre"
}
}
How to create a schema according to this JSON structure?

How do take the values from a large JSON response with multiple arrays and brackets?

I have a JSON response (over 500lines) , that has several arrays and brackets inside. Basically an overly nested response.
I am using Alamofire for fetching and i get a JSONData as response. But I don't know how to take values from the response and print it on a custom cell .
I am using Alamofire 5 to get the JSON response.
Please excuse if this sounds too newbieish , I am new to iOS developing.

JSON is a very simple format and easy to read. There are only two different collection types and four value types.
{} is a dictionary and is subscripted by key
[] is an array and is subscripted by index (zero-based)
Everything in double quotes is String, even "123" and "false"
false and true is Bool
Numeric values are Double, without fractional digits Int
<null> is NSNull
With SwiftyJSON you get distance in flightSegment with (root represents the top level object`)
root["availabilityResultList"][0]["availabilityRouteList"][0]["availabilityByDateList"][0]["originDestinationOptionList"][0]["fareComponentGroupList"][0]["boundList"][0]["availFlightSegmentList"][0]["flightSegment"]["distance"]

Filter Data in SwiftyJson

I have one SwiftyJson object.
I can not filter that array. I have tried this solution https://stackoverflow.com/a/37497170/4831567. But my json format is different that's why not working.
[
{
"name": "19860",
"header": {
"start_time": "1519270200",
"end_time": "1519299000",
"state": "lunch"
},
"alerts": "1",
"venue": {
"location": "Delhi, India",
"timezone": "+05:30"
},
"srs_category": [
0,
1
]
},
{
"name": "19861",
"header": {
"start_time": "1519270200",
"end_time": "1519299000",
"state": "Dinner"
},
"alerts": "1",
"venue": {
"location": "Mumbai, India",
"timezone": "+05:30"
},
"srs_category": [
1,
3
]
},
{
"name": "19862",
"header": {
"start_time": "1519270200",
"end_time": "1519299000",
"state": "lunch"
},
"alerts": "1",
"venue": {
"location": "Surat, India",
"timezone": "+05:30"
},
"srs_category": [
0,
2
]
}
]
i want to find that object that srs_category contain 1. I know it is possible by looping and condition. But i want via NSPredicate. If it is possible then please help me.
Thank You.

Here is easy way to use SwiftyJSON:
let filtered = JSON(yourArray).arrayValue.filter({
$0["srs_category"].arrayValue.map({ $0.intValue }).contains(1)
})

Use a Swift native function rather than NSPredicate
data represents the Data object received from somewhere
do {
if let json = try JSONSerialization.jsonObject(with:data) as? [[String:Any]] {
let srsCategory1 = json.first(where: { dict -> Bool in
guard let array = dict["srs_category"] as? [Int] else { return false }
return array.contains(1)
})
print(srsCategory1 ?? "not found")
}
} catch {
print(error)
}
If there are multiple items which can match the condition replace first with filter. Then the result is a non-optional array.

Argument type 'String' does not conform to expect type 'Sequence'

I am developing a app for ios and I am trying to get each letter of a member of dictionary which I have defined like this :
var Morse = ["a": "01", "b": "1000", "c": "1010", "d": "100", "e": "0", "f": "0010", "g": "110", "h": "0000", "i": "00", "j": "0111", "k": "101", "l": "0100", "m": "11", "n": "10", "o": "111", "p": "0110", "q": "1101", "r": "010", "s": "000", "t": "1", "u": "001", "v": "0001", "w": "011", "x": "1001", "y": "1011", "z": "1100", "1": "01111", "2": "00111", "3": "00011", "4": "00001", "5": "00000", "6": "10000", "7": "11000", "8": "11100", "9": "11110", "0": "11111", " ": "2"]
So for example, if the user enters a I would like to get "0" and then "1". To do this I use a counter :
var counter = 0
var letter: String = ""
var strings_letter: String = ""
letter = Morse[strings_letter]!
var number = Array(letter)[counter]
But this gives me an issue :
Argument type 'String' does not conform to expect type 'Sequence'
What am I doing wrong?

The characters property of a String instance contains a sequence of the characters contained in the String. You could, for a given key (say "a") re-map the .characters of the corresponding value ("01") to single-character String instances to obtain a String array:
if let charsForKeyA = Morse["a"]?.characters.map({ String($0) }) {
charsForKeyA.forEach { print($0) }
} /* 0
1 */

If I got it right, you want to get an array of characters for the value of the inserted key, based on your example, the output should be like:
"a" => ["0", "1"]
"b" => ["1", "0", "0", "0"]
"c" => ["1", "0", "1", "0"]
and so on...
var Morse = ["a": "01", "b": "1000", "c": "1010", "d": "100", "e": "0", "f": "0010", "g": "110", "h": "0000", "i": "00", "j": "0111", "k": "101", "l": "0100", "m": "11", "n": "10", "o": "111", "p": "0110", "q": "1101", "r": "010", "s": "000", "t": "1", "u": "001", "v": "0001", "w": "011", "x": "1001", "y": "1011", "z": "1100", "1": "01111", "2": "00111", "3": "00011", "4": "00001", "5": "00000", "6": "10000", "7": "11000", "8": "11100", "9": "11110", "0": "11111", " ": "2"]
let insertedKey = "a"
if let value = Morse[insertedKey] {
let array = Array(value.characters)
// here is your array!
print(array) // ["0", "1"]
}

Don't know how to use the JSON data returned from a web service

Apologies if this is not the right forum to ask, I couldn't think of anywhere else to take my question!
I'm trying to get the most recent weather forecast for a location using the following url http://datapoint.metoffice.gov.uk/public/data/val/wxobs/all/json/354379?res=hourly&key=47fbc7c3-dac4-424a-874d-7c8ff5b45b79
I want to get the weather type. The documentation here says that Weather Type would be a code number from 0-30. However the response from the web service (you can see for yourself following the long hyperlink above) is this:
{"SiteRep":{"Wx":{"Param":[{"name":"G","units":"mph","$":"Wind Gust"},{"name":"T","units":"C","$":"Temperature"},{"name":"V","units":"m","$":"Visibility"},{"name":"D","units":"compass","$":"Wind Direction"},{"name":"S","units":"mph","$":"Wind Speed"},{"name":"W","units":"","$":"Weather Type"},{"name":"P","units":"hpa","$":"Pressure"}]},"DV":{"dataDate":"2013-03-15T17:00:00Z","type":"Obs"}}}
Now I have no trouble reading that information into an NSDictionary object in my IOS app. But i just can't see which bit contains a code number from 0-30!
If you're wondering if i'm using the right request url, i'm pretty sure i am, i got it from the documentation here. (scroll down a little ways.)
I'm just stumped on how to extract the weather type code. I might have gotten myself completely confused and be making the wrong request, their documentation is not very user friendly. As a novice i really need help using this service, but i couldn't find any tutorials with google. Really appreciate anyone who takes the time to look! It would be such a help just to get a second opinion.

actually the response you are getting is incomplete ...complete response is as follows
