Problem to initialize iDangerous Swiper

Within my controller i have declared my Swiper object:

var swiperTest = new Swiper('.swiper-container-test', {
    initialSlide: 2,
    slidesPerView: 5,
    observer: true,
    observeParents: true,
    centeredSlides: true,
    paginationClickable: true,
    spaceBetween: 10,
    width: 1400

Within browser no problem, but inside my iOS app this doesn’t work.
Maybe i have configured badly something, but i don’t understand what.

I know it’s a bit old , but I have same issue . Did you find a solution ?

Unfortunately no, I’ve applied this to obtain the same effect:
