LABParser

Bidirectional JSON-Dictionary/Object parser development in swift 4.

Requirements • Installation • Usage • Contribution • Author • License

Requirements

• iOS 10.0+
• Xcode 9.0+
• Swift 4.0+

Installation

CocoaPods

Install CocoaPods if it is not already available:

$ [sudo] gem install cocoapods
$ pod setup

If you already have cocoapods, update it:

$ pod update

Go to the directory of your Xcode project, and Create and Edit your Podfile and add LabParser:

$ cd /path/to/MyProject
$ nano Podfile

platform :ios, '11.0'
use_frameworks!

target 'MyProject' do
 pod 'LABParser', '~> 0.1'
end

Install it into your project:

$ pod install

Open your project in Xcode from the .xcworkspace file (not the usual project file):

$ open MyProject.xcworkspace

You can now import LABParser framework into your files.

Usage

LABParser is a bidirectional JSON-Dictionary/Object parser development in swfit 4.

In order to usage this pod, you need import LABParser into yours model objects.

LABParser act through a class named ParcelableModel. You must inherits all your models of this class to use properly LABParser. We encourage you to create a BaseModel class to import LABParser only in it. This BaseModel class must be open to allow inherits.

import Foundation
import LABParser

open class BaseModel: ParcelableModel {

}

Now create your models class.

import Foundation

class User: BaseModel {

	var email: String!
	var password: String!

	required init(){
		super.init()
	}

	init(email: String, password: String) {
		super.init()
		self.email = email
		self.password = password
	}
}

So, suppose that you receive a JSON User object like this in a variable named data:

{
	"email": "limpusra@gmail.com",
	"password": "aom123"
}

You can convert it to your swift model with:

let user = User()
do {
	user.fromJSON(data)	
} catch {
	print("The string isn't a valid JSON")
}

Must use try catch blocks to do error handling.

If you receive a Dictionary representation of your User object you can parser doing:

let user = User()
user.fromDictionary(data)

Then you can use the object atributes:

print("Email user is: /(user.email) and password: /(user.password)")

If you receive a dictionary array you can parser it doing:

let userArray: [User] = User.fromDictionaryArray(data)

Note that your models atributtes must be exactly same of the JSON/Dictionary key name. However, if you have any key tath doesn't match with the model you can override the function 'customKeysName', create a custom dictionary of keys and return it:

override func customKeysName() -> [String: String]? {
	return ["email": "user_email",
			"password": "U.Password"]
}

To create a dictionary from a model, your ParcelableModel must be initialized:

let user = User(email: "limpusra@gmail.com", password: "aom123")

so, create a dictionary it's simple like:

let userDictionary: [String: AnyObject] = user.toDictionary()

to create a JSON String from a model:

do {
    let jsonString = try user.toJSON()
    print("toJSON: " + jsonString)
} catch {
    print("The model can't be parsed to JSON format")
}

To Consider

• All yours models must inherits from ParcelableModel. To import only in a class, you can create a BaseModel to it and all yours models inherits from BaseModel.
• Your atributtes models must be exactly the same of the JSON/Dictionary key name or you must override the function 'customKeysName' in your model class.
• If you have properties of type Int, Float or Double then you must change these types to NSNumber.
• If you have properties of type Bool, you must initialize these in their declaration. You can convert it to NSNumber too.
• LABParser can parser atributes of ParcelableModel objects type like:

import Foundation

class Token: BaseModel {

	var defaultToken: String!
	var attempts: NSNumber?
	var refreshToken: String!

	required init(){
		super.init()
	}
}

import Foundation

class User: BaseModel {

	var email: String!
	var password: String!
	var token: Token!

	required init(){
		super.init()
	}
}

• LABParser can parser arrays of ParcelableModel objects like:

{
	"email": "limpusra@gmail.com",
	"password": "aom123",
	"offices": [
		{
			"name": "LAB 1",
			"address": "Street 1"
		}, 
		{
			"name": "LAB 2",
			"address": "Street 2"
		}
	]
}

With a propertly model:

import Foundation

class Office: BaseModel {

	var name: String!
	var address: String!

	required init(){
		super.init()
	}
}

import Foundation

class User: BaseModel {

	var email: String!
	var password: String!
	var offices: [Office]!

	required init(){
		super.init()
	}
}
