{% tab title="Swift Package Manager (SPM)" %}
SPM has a few issues when it comes to caching its dependencies, so please be sure to follow all the steps below:

* Trigger an update of SPM using your preferred method ( <kbd>Right Click</kbd> → <kbd>Update Package</kbd> or <kbd>Swift Packages</kbd> → <kbd>Update to Latest Package Versions</kbd>)
* Clear Derived Data
* Clean Build
* Run the app again, and verify `ContextManager.sdkVersion()` is the latest version.

Alternatively, you can also specify the specific version of ContextSDK you want to use in your `Package.swift` or Xcode SPM settings.

### Validate the installation

After updating the SDK, please take a minute to go through the [release checklist](https://docs.contextsdk.com/context-decision/release-checklist) again, to ensure the SDK is correctly installed and configured, using the `validate` method. Just following the first step of the release checklist will prevent almost all potential integration errors.
