src/Generator.php:80

• [nitpick] Consider adding a return type declaration : bool to the generate method to leverage PHP 7.1+ typing features.

    public function generate(ShopInfo $shopInfo, iterable $currencies, iterable $categories, iterable $offers, iterable $deliveries = [])

src/Generator.php:234

• You can add a : void return type to this private method to make its signature explicit now that PHP 7.1+ is required.

    private function addCurrencies(iterable $currencies)

src/Generator.php:253

• Consider specifying : void as the return type for consistency with PHP 7.1+ features.

    private function addCategories(iterable $categories)

src/Generator.php:272

• Add an explicit : void return type for clarity now that PHP 7.1+ is enforced.

    private function addDeliveries(iterable $deliveries)

src/Generator.php:291

• It might be helpful to declare a : void return type here to fully adopt PHP 7.1+ typing.

    private function addOffers(iterable $offers)

@Bukashk0zzz I have done it, but it seems that php8.4 tests will fail, because of old versions of dev packages

[Bukashk0zzz]

@vaiil do you will be able to fix tests pipeline?

[vaiil]

@Bukashk0zzz I've updated some dev packages. Can you rerun actions now?
