# Deliverables

NFC Wallet SDK for iOS is delivered as a set of libraries that you import into your digital wallet application. The delivery package also includes API documentation to help you integrate the SDK.

## Included libraries

The delivery package includes the following artifacts:

* `TSHPaySDK.xcframework`
  * The NFC Wallet SDK for iOS.
  * Location in the release package: `binary/TSHPaySDK-<version number>-<build type>.zip`
* `SecureLogAPI.xcframework`
  * Used by NFC Wallet SDK to securely store SDK logs for troubleshooting.
  * Location in the release package: `binary/SecureLogAPI.zip`

## Build types

`<build type>` is one of:

* `Release`
  * Use for Production Environment deployments after your digital wallet application has passed required validation.
* `Debug`
  * Functionally equivalent to `Release`, with the following differences:
    * Logging is enabled to support development and troubleshooting.
    * Anti-debugger is disabled.

{% hint style="warning" %}
**Use the correct build type**

Use each build type only for its intended purpose. During [SDK initialization](/nfc-wallet-sdk-ios/get-started/configuration/3.-initialization.md), the SDK returns `deviceEnvironmentUnsafe` in these cases:

* You use the `Debug` build in production. Error is reported during the SDK initialization if the application is signed with a distribution or ad-hoc certificate (`Debug` is only intented for development purposes).
* You debug the `Release` build (including when the app is launched from Xcode or via `xcodebuild`).
