# Debug

## Using debug mode

When debug mode is enabled, exceptions will be thrown when the tracker is not started properly. 

{% hint style="info" %}
**Note:** When you are ready to submit the app for review, remember to disable debug mode.
{% endhint %}

### Enable debug mode for iOS

For iOS, you can switch between logging tiers to see output from the tracker to help you with integration. There are four logging tiers:

* **verbose:** output everything
* **debug:** output debug related info, warning and error
* **warning:** output warnings and errors
* **error:** output errors (see property `loglevel`)

All log output has the format `[CB]: xxxx`

#### **Objective-C**

```objectivec
[CBTracker sharedTracker].debugMode = true;
[CBTracker sharedTracker].logLevel = CBTrackerLogLevelVerbose;i
```

#### **Swift**

```objectivec
CBTracker.shared().debugMode = true
CBTracker.shared().logLevel = .verbose
```

### Enable debug mode for Android

Set `com.chartbeat.androidsdk.DEBUG` to true before your first call to `setupTracker`.

### Enable debug mode for React Native

#### Turn on verbose native logs

```
Chartbeat.setDebugMode(true);
```

Call this immediately after setupTracker.

#### iOS — view native logs

Open **Console.app**, filter by the iOS Simulator process, and search for Chartbeat-related messages, or stream from the terminal:

```
xcrun simctl spawn booted log stream --level debug --style compact \
  --predicate 'eventMessage CONTAINS "[CB]:Pinging"'
```

#### Android — view native logs

Open **Logcat** in Android Studio, or stream from the terminal:

```
adb logcat -T 1 | grep -i pingclient
```
