Meta Wearables Device Access Toolkit for iOS

The Meta Wearables Device Access Toolkit enables developers to utilize Meta's AI glasses to build hands-free wearable experiences into their mobile applications. By integrating this SDK, developers can reliably connect to Meta's AI glasses and leverage capabilities like video streaming and photo capture.

The Wearables Device Access Toolkit is in developer preview. Developers can access our SDK and documentation, test on supported AI glasses, and create organizations and release channels to share with test users.

Developer Terms

• By using the Wearables Device Access Toolkit, you agree to our Meta Wearables Developer Terms, including our Acceptable Use Policy.
• By enabling Meta integrations, including through this SDK, Meta may collect information about how users' Meta devices communicate with your app. Meta will use this information collected in accordance with our Privacy Policy.
• You may limit Meta's access to data from users' devices by following the instructions below.

Opting out of data collection

To configure analytics settings in your Meta Wearables DAT iOS app, you can modify your app's Info.plist file using either of these two methods:

Method 1: Using Xcode (Recommended)

1. In Xcode, select your app target in the Project navigator
2. Go to the Info tab
3. Navigate to Custom iOS Target Properties and find the MWDAT key
4. Add a new key under MWDAT called Analytics of type Dictionary
5. Add a new key to the Analytics dictionary called OptOut of type Boolean and set the value to YES

Method 2: Direct XML editing

Add or modify the following in your Info.plist file.

<key>MWDAT</key>
<dict>
    <key>Analytics</key>
    <dict>
        <key>OptOut</key>
        <true/>
    </dict>
</dict>

Default behavior: If the OptOut key is missing or set to NO/<false/>, analytics are enabled (i.e., you are not opting out). Set to YES/<true/> to disable data collection.

Note: In other words, this setting controls whether or not you're opting out of analytics:

• YES/<true/> = Opt out (analytics disabled)
• NO/<false/> = Opt in (analytics enabled)
