Synospis

This pod is a Swift interface to the Recast.AI API. It allows you to make requests to your bots.

Requirements

• iOS 10.0+
• Xcode 8.0+

Installation

RecastAI is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "RecastAI"

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

RecastAIClient

This class handles everything. Create a RecastAIClient object and init it with your token. The RecastAIClient can also be instanciated with a language (optional).

import RecastAI

class ViewController: UIViewController
{
    //Vars
    var bot : RecastAIClient?

    override func viewDidLoad()
    {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        self.bot = RecastAIClient(token : "YOUR_TOKEN")
        self.bot = RecastAIClient(token : "YOUR_TOKEN", language: "YOUR_LANGUAGE")
    }
}

Specs

Classes

This module contains 3 classes, as follows:

• Client is the client allowing you to make requests.
• Response contains the response from Recast.AI.
• Intent represents an Intent of the response

Don’t hesitate to dive into the code, it’s commented ;)

class Client

The Client can be instanciated with a token and a language (both optional).

let bot = RecastAIClient(token : "YOUR_TOKEN", language: "YOU_LANGUAGE")

Your tokens:

Copy paste your request access token from your bot’s settings.

Your language

let bot = RecastAIClient(token : "YOUR_TOKEN", language: "en")

The language is a lowercase 639-1 isocode.

Text Request

The textRequest method allows you to make a request to the Recast.AI API. The textRequest method is to make a Text request and takes a text as a String as parameter and a language as a String or a Token as optional parameters. You also need to provide a successHandle and a failureHandle functions that will be called when either the request is done or the request fails. If you pass a token or a language in the options parameter, it will override your default client language or token.

/**
Make text request to Recast.AI API
*/
func makeRequest()
{
    //Call makeRequest with string parameter to make a text request
    self.bot?.textRequest(<#T##request: String##String#>, successHandler: <#T##(Response) -> Void#>, failureHandle: <#T##(Error) -> Void#>)
}

If a language is provided: the language you’ve given is used for processing if your bot has expressions for it, else your bot’s primary language is used.

If no language is provided: the language of the text is detected and is used for processing if your bot has expressions for it, else your bot’s primary language is used for processing.

Text Converse

The textConverse method allows you to make a request to the Recast.AI Bot Builder API. The textConverse method is to make a Converse request and takes a text as a String as parameter and a language as a String, a Token, a ConverseToken as optional parameters. You also need to provide a successHandle and a failureHandle functions that will be called when either the request is done or the request fails. If you pass a token or a language in the options parameter, it will override your default client language or token. The converse token is unique ID you need to provide in order to access the a specific conversation.

/**
Make text request to Recast.AI API
*/
func makeRequest()
{
//Call makeRequest with string parameter to make a converse request
self.bot?.textConverse(<#T##request: String##String#>, converseToken: "YOUR_CONVERSATION_UNIQUE_ID", successHandler: <#T##(Response) -> Void#>, failureHandle: <#T##(Error) -> Void#>)
}

File Request

In order to make a File Request you need to implement two methods you need to pass a file as a parameter. You also need to provide a successHandle and a failureHandle functions that will be called when either the request is done or the request fails. If you pass a token or a language in the options parameter, it will override your default client language or token.

file format: .wav

/**
Make File request to Recast.AI API
*/
func makeFileRequest()
{
    if (!(self.requestTextField.text?.isEmpty)!)
    {
        let url = URL(string: self.requestTextField.text!)!
        //Call makeRequest with string parameter to make a text request
        self.bot?.fileRequest(<#T##audioFileURL: URL##URL#>, successHandler: <#T##(Response) -> Void#>, failureHandle: <#T##(Error) -> Void#>)
    }
}

class Response

The Response is generated after a call to either fileRequest or textRequest.

Get the first detected intent

/**
Method called when the request was successful

- parameter response: the response returned from the Recast API

- returns: void
*/
func recastRequestDone(_ response : Response)
{
    let intent = response.intent()
    print(intent.slug)
}

Get one entity

/**
Method called when the request was successful

- parameter response: the response returned from the Recast API

- returns: void
*/
func recastRequestDone(_ response : Response)
{
    let location = response.get('location')
}

Get all entities matching name

/**
Method called when the request was successful

- parameter response: the response returned from the Recast API

- returns: void
*/
func recastRequestDone(_ response : Response)
{
    let locations = response.all('location')
}

Attributes

Each of the following methods corresponds to a Response attribute

Attributes

Each of the following methods corresponds to a Response attribute

In addition to those methods, more attributes are generated depending of the nature of the entity. The full list can be found there: man.recast.ai

/**
Method called when the request was successful

- parameter response: the response returned from the Recast API

- returns: void
*/
func recastRequestDone(_ response : Response)
{
    let location = response.get('location')
    print(location["latitude"])
}

Error

We will call recastRequestError with Error as parameter. For more information about Recast Errors check out our man#error
