## Migrating Veriff iOS SDK from 3 to 4

`Veriff` **instances renamed to** `VeriffSdk`

The name `Veriff` was used both for our module and public class name. This blocked us from supporting Swift Package Manager due to [Swift compiler bug](https://bugs.swift.org/browse/SR-898). We renamed our public class name to `VeriffSdk`.

**Following structs have been moved:**

- `VeriffConfiguration` struct is moved under `VeriffSdk.Configuration` (replace the occurrences of `VeriffConfiguration` with `VeriffSdk.Configuration`)
- `Branding` `VeriffSdk.Branding` (replace the occurrences of `Branding` with `VeriffSdk.Branding`)
- `VeriffDelegate` struct is moved under `VeriffSdkDelegate `(replace the occurrences of `VeriffDelegate` with `VeriffSdkDelegate`)

**Following are now mandatory:**

- `VeriffSdk.Result.description` (if you had issues with unwrapping it, feel free to remove it)

**Other changes**

`VeriffSdk.Result.sessionToken` removed and `VeriffSdk.Result.sessionUrl` added instead.

Remove the occurrences of `sessionToken`. You can now use `sessionUrl` to get the full `sessionUrl` including token.

## Migrating Veriff iOS SDK to 3

**Switch from** `baseUrl` **and** `sessionToken` **to** `sessionUrl`

The `Veriff` object in the SDK 3.0.0 takes a required `sessionUrl` and an optional `VeriffConfiguration` instance as parameters into initialisation. The `sessionUrl` is received from your backend implementation (namely the respone of the [POST /sessions](https://veriff-dev-documentation.document360.io/apidocs/v1sessions)[↗] call), it is composed of the `baseUrl` and `sessionToken` sent to the `VeriffConfiguration` object in earlier versions.

**Updated** `VeriffConfiguration` **object**

The `VeriffConfiguration` struct now takes in `branding` and `languageLocale` as initialisation parameters.

**The new** `VeriffDelegate` **method**

You can now receive session results via `func sessionDidEndWithResult(_ result: Veriff.Result)` instead of the obsolete `func onSession(result: VeriffResult, sessionToken: String)`. The `sessionToken` is included in the `Veriff.Result` as an instance variable.

**Use** `Veriff.Result` **instead of** `VeriffResult`

The new `Veriff.Result` struct comprises `status: Status` and `sessionToken: String?` instance variables. The `Status` enum can be of three types: `done`, `canceled`, `error`. The `description` variable on the `Veriff.Result` returns additional information as a string.
