DeviceData Module

Adds information about the device to the data layer.


The DeviceData module gathers information about the current device and adds it to the data layer. Usage of this module is recommended.

The following platforms are supported:

  • iOS
  • tvOS
  • watchOS
  • macOS


  • UIKit
  • Darwin
  • CoreTelephony
  • WatchKit


This module is included as part of the Core library and does not require separate installation.


To initialize the module, verify that it’s specified on the TealiumConfig collectors property

config.collectors = [Collectors.DeviceData]

If you don’t specify any optional collectors on your TealiumConfig instance, then this module is automatically enabled.
