<array>
    <string>com.yourCompanyName.appName</string>
</array>

Answer 2

2. Copy and paste "BGTaskSchedulerPermittedIdentifiers" under the Information Property List column. This will create an array in the Type column.
3. Click the add button on the item you just created to add background task identifiers for the array.
4. Note that it is recommended by apple to mention task background task identifier in reverse domain notation(com.something.name).

In the end, it will look like this,
