# Getting Started

In this guide we show how to use it.

A sample application is available at: <https://github.com/blocto/blocto-ios-sdk/tree/main/Example>

## Installation

An easy way to add Blocto iOS SDK dependency to an iOS project is through *CocoaPods*, like this:

```ruby
pod 'BloctoSDK/EVMBase'
```

The dependency can be installed simply by `pod install`:

```ruby
pod install
```

{% hint style="warning" %}
Blocto wallet supports EVMBase staring from version 3.8.0.
{% endhint %}

## Usage

#### Initialize Blocto SDK

```swift
BloctoSDK.shared.initialize(
    with: "YOUR_APP_ID", // required
    window: yourWindow, // required PresentationContextProvider of web SDK authentication.
    logging: true, // optional (default is true)
    environment: .dev // optional (default is prod)
)
```

{% hint style="info" %}
parameter `environment`:\
in Ethereum`dev` for Goerli and `prod` for mainnet.\
in BSC`dev` for testnet and `prod` for mainnet.\
in Polygon`dev` for Mumbai and `prod` for mainnet.\
in Avalanche`dev` for FUJI Testnet and `prod` for mainnet.
{% endhint %}

#### UIApplicationDelegate delegate method implementation

```swift
func application(
    _ app: UIApplication,
    open url: URL,
    options: [UIApplication.OpenURLOptionsKey: Any] = [:]
) -> Bool {
    BloctoSDK.shared.application(
        app,
        open: url,
        options: options)
    return true
}
```

```swift
func application(
    _ application: UIApplication,
    continue userActivity: NSUserActivity,
    restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void
) -> Bool {
    BloctoSDK.shared.continue(userActivity)
    return true
}
```
