Profile field create and set default value programmatically

Question

I need the checkbox to be checked by default. Below is my code, notice the 'default_value' under the settings array.

$field_instance = array(                                      
    'field_name'    => $fielddef['field_name'],               
    'type'          => 'list_boolean',                        
    'entity_type'   => 'user',                                
    'bundle'        => 'user',                                
    'label'         => t($opts['label']),                     
    'description'   => t($opts['description']),               
    'required'      => FALSE,                                 
    'widget'        => array(                                 
        'type'      => 'options_onoff',                       
        'weight'    => 10,                                    
    ),                                                        
    'settings'      => array(                                 
        'allowed_values' => drupal_map_assoc(range(0,1)),     
        'default_value' => array(array('value' => 1))         
    )                                                         
);
field_create_instance($field_instance); 

I have tried using 'default_value' in the $field_instance array, I've also tried 'default_value_function' without success. I feel like I'm close on this, what am I missing? Thanks!

Try with this

$field_instance = array(                                      
'field_name'    => $fielddef['field_name'],               
'type'          => 'list_boolean',                        
'entity_type'   => 'user',                                
'bundle'        => 'user',                                
'label'         => t($opts['label']),                     
'description'   => t($opts['description']),               
'required'      => FALSE,                                 
'widget'        => array(                                 
    'type'      => 'options_onoff',                       
    'weight'    => 10,                                    
),                                                        
'settings'      => array(                                 
    'allowed_values' => drupal_map_assoc(range(0,1)),     
    'default_value' => array(1),         
)                                                         

);
