intController() and __construct()

I have just noticed that I cannot access the variables initiated in BaseController initController method in the constructors of my controllers...

I have

$this->settingsModel = model('SettingsModel');
$this->settings = $this->settingsModel->keyValue();

in my BaseController initController method, and running

$hl = explode('-', $this->settings['booking_hours']);

in controller methods goes fine, but if I do this in

function __construct()

I get an error

Undefined property: App\Controllers\Booking::$settings

What would be the correct way to do things here? Maybe use initController with a parent call in my controller classes instead of __construct()? I could, of course, simply initiate the needed model and run the

$this->settings = $this->settingsModel->keyValue();

in the constructor...
