# Migration guide from v8.2 to v8.3 for Web3Auth PnP iOS SDK

## Overview

This migration guide provides steps for upgrading from version 8.2(v8.2) to version 8.3(v8.3) of the Web3Auth PnP iOS SDK. The guide outlines significant changes and enhancements, including the introduction of new login providers, and changes in `request` method.

## Changes in detail

### `request` method updates

From v8.3, developers can pass the `chainConfig` to request the signature for specific chain. To further improve developer experience, we have removed the `loginParams` from the `request` method.

#### Before (v8.2)

```swift title="Usage"
var params = [Any]()
params.append("Hello, Web3Auth from Android!")
params.append("0x764dd67c0420b43a39ab337463d8995622f226a2")
params.append("Web3Auth")

do {
  // focus-start
  try await self.web3Auth?.request(
    W3ALoginParams(loginProvider: .GOOGLE, mfaLevel: .NONE),
    method: "personal_sign",
    requestParams: params
  )
  // focus-end
} catch {
  // Handle error
}
```

#### After (v8.3)

```swift title="Usage"
var params = [Any]()
params.append("Hello, Web3Auth from Android!")
params.append("0x764dd67c0420b43a39ab337463d8995622f226a2")
params.append("Web3Auth")

var chainConfig = ChainConfig(
    chainNamespace: ChainNamespace.eip155,
    chainId: "0x1",
    rpcTarget: "https://mainnet.infura.io/v3/${key}",
    ticker: "ETH"
)

do {
  // focus-start
  try await self.web3Auth?.request(
    chainConfig: chainConfig
    method: "personal_sign",
    requestParams: params,
  )
  // focus-end
} catch {
  // Handle error
}
```

### New Login providers

v8.3 update brings two new providers. Now developers can use the SMS Passwordless and Farcaster login options.

#### SMS Passwordless

```swift

let web3auth = try await Web3Auth(W3AInitParams(
  clientId: "YOUR_WEB3AUTH_CLIENT_ID", // Pass your Web3Auth Client ID, ideally using an environment variable
  network: .sapphire_mainnet,
  redirectUrl: "bundleId://auth"
))

 // focus-start
let result = try await web3Auth.login(W3ALoginParams(
  Web3AuthProvider.SMS_PASSWORDLESS,
  // The phone number should be in format of +{country_code}-{phone_number}
  extraLoginOptions: .init(loginHint: "+91-9911223344")
))
 // focus-end
```

#### Farcaster

```swift title="Usage"
let result = try await Web3Auth().login(
    // focus-next-line
    W3ALoginParams(loginProvider: .Farcaster)
)
```
