# DT Exchange Logging on iOS

The DT Exchange iOS SDK includes a built-in logging utility, `DTXLogger`, that monitors SDK behavior and streamlines integration debugging. You can control how much detail appears in the console output by setting the desired log level.

Set the log level before or immediately after calling `initWithAppID()` to ensure that initialization events are logged.

The following table describes the log level attributes.

| Property Name | Description                                               |
| ------------- | --------------------------------------------------------- |
| `.debug`      | <p>Enables full logging.<br>Use this for development.</p> |
| `.off`        | <p>Disables all logging.<br>Use this for production.</p>  |

## Setting the Log Level

To configure the library's logging level, call `DTXLogger.setLogLevel` and pass the desired log level.

The following example initializes the SDK and then sets the log level to `.debug`:

{% code title="Swift" %}

```swift
IASDKCore.sharedInstance()?.initWithAppID(
    appId,
    completionBlock: { success, error in
        if let error {
            print("DTExchange init failed: \(error.localizedDescription)")
        } else {
            print("DTExchange init success")
        }
    },
    completionQueue: .main
)

// Set the desired log level
// Use .debug for full logs during development or .off for production
DTXLogger.setLogLevel(.debug)
```

{% endcode %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.digitalturbine.com/dt-exchange/sdk-configuration/integrating-the-ios-sdk/dt-logging-on-ios.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
