Using view layouts echoes void return type.

This looks like an error in the user guide. You are right, extend() return void, there's nothing to echo.

PHP Code:

    /**
    * Specifies that the current view should extend an existing layout.
    * @param string $layout
    * @return void
    */
    public function extend(string $layout)
    {
        $this->layout = $layout;
    }

...and it's the same with section() and endSection().

This:

PHP Code:

<?= $this->extend('default') ?>

<?= $this->section('content') ?>
    <h1>Hello World!</h1>
<?= $this->endSection() ?>

...should be this:

PHP Code:

<?php $this->extend('default') ?>

<?php $this->section('content') ?>
    <h1>Hello World!</h1>
<?php $this->endSection() ?>
