iOS Example application

This application is a Proof Of Concept, designated to demonstrate (simulate) communication between Salt Edge API and Mobile Client.


  • iOS 12.0+ / macOS 10.13+
  • Swift 5+

Salt Edge iOS / macOS Swift SDK

A handful of classes to help you interact with the Salt Edge API from your iOS / macOS app. Last SDK version (3+) supports Salt Edge API v5.


  • iOS 10.0+ / macOS 10.13+
  • Swift 5+

Installation via CocoaPods

Add the pod to your Podfile

for Salt Edge API v5 use

pod 'SaltEdge-iOS-Swift', '~> 3.3.13'

for Salt Edge API v4 (Deprecated) use

pod 'SaltEdge-iOS-Swift', '~> 1.1.2'

Install the pod

$ pod install

Import SDK into your app

import SaltEdge

Init SDK

Replace the appId, appSecret.

To setup Salt Edge API, call in AppDelegate.swift:

SERequestManager.shared.set(appId: appId, appSecret: appSecret)

Note: You can find your appId and appSecret on your secrets page (Eligible only for Salt Edge API). customerId - is the unique identifier of the new customer.


A class designed with convenient methods for interacting with and querying the Salt Edge API. Contains methods for fetching entities (Connections, Transactions, Accounts, etc.), for requesting connect url for creating, reconnecting and refreshing Connections via a SEWebView, and also for creating Connections via the REST API.

Each successful request via SERequestManager returns SEResponse containing data and meta.

Each failed request returns standard Swift Error .

Use the manager to interact with the provided API:

let connectionParams = SEConnectionParams(
    consent: SEConsent(scopes: ["account_details", "transactions_details"]),
    countryCode: "XF",
    providerCode: "fakebank_simple_xf",
    credentials: ["login": "username", "password": "secret"]
SERequestManager.shared.createConnection(with: connectionParams) { response in
    switch response {
    case .success(let value):
        // is a valid SEConnection
    case .failure(let error):
        // Handle error

Get customer secret

To access the Salt Edge SDK functionality, it is necсessary to get a Customer secret. To get a customer secret, you can make a request via SERequestManager.

After successful request, you should link the received customer secret with the request manager:

SERequestManager.shared.set(customerSecret: "received-customer-secret")

Note: You must save the received customer secret in you storage(e.g. UserDefaults) and for all future Salt Edge SDK usage, you should link the stored customer secret.


let defaults = UserDefaults.standard
if let secret = defaults.string(forKey: "customerSecret") {
    SERequestManager.shared.set(customerSecret: secret)
} else {
    let params = SECustomerParams(identifier: "your-customer-unique-id")
    SERequestManager.shared.createCustomer(with: params) { response in
        switch response {
        case .success(let value):
            // Save customer secret to your storage and then link it with API manager
            defaults.set(, forKey: "customerSecret")

            case .failure(let error):
            // Handle error


A small WKWebView subclass for using Salt Edge Connect within your iOS app.


Let your view controller conform to the SEWebViewDelegate protocol.

class MyViewController : UIViewController, SEWebViewDelegate {
  // ... snip ...

Instantiate a SEWebView and add it to the controller:

let connectWebView = SEWebView(frame: self.view.bounds)
connectWebView.stateDelegate = self

Implement the SEWebViewDelegate methods in the controller:

// ... snip ...

func webView(_ webView: SEWebView, didReceiveCallbackWithResponse response: SEConnectResponse) {
    switch response.stage {
    case .success:
	    // Connection successfully connected
    case .fetching:
	    // Connection is fetching. You can safe connection secret if it is present.
    case .error:
	    // Handle error

func webView(_ webView: SEWebView, didReceiveCallbackWithError error: Error) {
	// Handle error

Load the Salt Edge Connect URL into the web view and you're good to go:

SERequestManager.shared.createConnectSession(params: connectSessionParams) { response in
	switch response {
	case .success(let value):
		if let url = URL(string: {
		    self.webView.load(URLRequest(url: url))
	case .failure(let error):
		// Handle error


There are some provided models for serializing the objects received in the API responses. These represent the Providers, Connections, Accounts, Transactions, provider fields and their options. Whenever you request a resource that returns one of these types, they will always get serialized into Swift structures. For instance, the getAllTransactions(for connectionSecret: String, params: SETransactionParams? = nil, completion: SEHTTPResponse<[SETransaction]>) method has a SEResponse containing data and meta where data is [SETransaction] in it's success callback.

Models, contained within the components:

  • SEProvider
  • SEConnection
  • SEAccount
  • SETransaction
  • SEConnectSessionResponse
  • SEAttempt
  • SEConsent
  • SECountry
  • SECustomer
  • SEStage
  • SEError
  • SEProviderField
  • SEProviderFieldOption

For a supplementary description of the models listed above that is not included in the sources docs, feel free to visit the Salt Edge API Reference

Models extra

Some of models have extra field of type [String: Any]. In case you need to get any field, you can do the following:

let account = SEAccount()

guard let accountExtra = account.extra else { return }

let anyValue = accountExtra["string_key"]

Some of key-pairs have predifinied extensions:

let transaction = SETransaction()

guard let transactionExtra = transaction.extra else { return }

let possibleDuplicate: Bool = transactionExtra.possibleDuplicate


Documentation is available for all of the components. Use quick documentation (Alt+Click) to get a quick glance at the documentation for a method or a property.

Running the demo

To run the contained here demo app, you have to set the demo with your App ID, App Secret and choose desired API.

To setup Salt Edge API, call:

SERequestManager.shared.set(appId: appId, appSecret: appSecret)

Set up the appId, appSecret and customerId constants to your App ID and corresponding App Secret in AppDelegate.swift:49-51.


The current version of the SDK is 3.3.13, and supports the latest available version of Salt Edge API. Any backward-incompatible changes in the API will result in changes to the SDK.


The SDK uses SSL pinning. This means that every API request that originates in SEAPIRequestManager will have SSL certificate validation.

Since version 1.1.0

The SDK has moved to HTTP Public Key Pinning (HPKP)
