Replace string text to particular text in an array string with in ios swift

Question

entities = ({confidence = "<null>"; end = 113; entity = DATE; extractor = "ner_spacy";start = 103;value = "five years"; }, {confidence = "<null>"; end = 177;entity = ORG; extractor = "ner_spacy";start = 163; value = "xyz Company"; } );

This is the backend data, I need to display in string with remove and add the new values in a string text:

Example: "In your {{years_of_experience}} of experience at {{ORG}}, what kind of process improvements or standards setup?"

Answer : Array of 0 ---> five years and Array of 1 ---> xyz Company Instead of open and closed curly brackets, I need to show this text of array 0 and 1.

In your five years of experience at xyz company, what kind of process improvements or standards setup?

Based on which key you identify the type of data you need to enter in the string? — PGDev, May 24 '19 at 07:06
What have you tried, could you share your current code? Could you also add a correct example json message, there is no "years_of_experience" in your example. — Joakim Danielson, May 24 '19 at 08:01

I've tried to get a solution for your problem,

This is the JSON response that I've used as an example,

[
    {
        "confidence": "<null>",
        "end": 113,
        "entity": "DATE",
        "extractor": "ner_spacy",
        "start": 103,
        "value": "five years"
    },
    {
        "confidence": "<null>",
        "end": 177,
        "entity": "ORG",
        "extractor": "ner_spacy",
        "start": 163,
        "value": "xyz Company"
    }
]

Parse the JSON response using Codable into an array of Entity objects, i.e.

struct Entity: Codable {
    var confidence: String?
    var end: Int?
    var entity: String?
    var extractor: String?
    var start: Int?
    var value: String?
}

I've used entity key in the response to identify which value to replace, i.e.

if let data = str.data(using: .utf8) { //You'll get this data from API response
    let entities = try? JSONDecoder().decode([Entity].self, from: data)

    var sentence = "In your {{DATE}} of experience at {{ORG}}, what kind of process improvements or standards setup?"
    entities?.forEach({
        if let entity = $0.entity, let value = $0.value {
            sentence = sentence.replacingOccurrences(of: "{{\(entity)}}", with: value)
        }
    })
    print(sentence) //In your five years of experience at xyz Company, what kind of process improvements or standards setup?
}

In the above code, I've traversed the entities array and replaced each occurrence of the {{entity}} with the respective value, i.e.

"{{DATE}}" is replaced with "five years"
"{{ORG}}" is replaced with "xyz Company"

Let me know in case you still face any issues or if I haven't understood the problem statement well.

@JoakimDanielson Yeah that's right. Didn't see the Swift-3 requirement. — PGDev, May 24 '19 at 08:11

It is not working for dynamic data, In some text doesn't contain any key values and {{}}, In that case how we will write this.

I need to display an tableview with this type of data and play the voice message.

Example: q1) Can you please explain to me about yourself, highlighting the number of years of experience relevant to Project Manager and different domains you worked on

Answer: User says the answer, sends the backend and stored the response in a dictionary.

Q2) In your {{years_of_experience}} of experience at {{ORG}}, what kind of process improvements or standards setup? Note: 1) I need to replace the text value inside of the {{ }} 2) For some question text there is no entity key and value. 3) We need to store {{ORG}} value and Whenever question text inside {{ORG}} we should replace the value of entity.

Q3) Could you tell me a few Software development methodologies and what you have used and are comfortable with?

q4) Great. Can you name a few clients you were supporting in {{industry}} domain and {{years_of_experience}}?

------------ and Soon.

I stored the entity key and value response whenever says the answers with respective text
