Swiper breaks during build

[hillbilly991]

Not sure why but swiper works fine on my localhost but when I build the app, it totally breaks. Mobile version of the page uses swiper for every page (so the user flicks through and fills in information on each slide). The user shouldn't be able to go to the next slide until they have filled in all their information. But on the build, they fill their information and then it goes to a white, blank page and the user can swipe to other blank pages whilst intermediately seeing a slide (so basically doing the opposite of its intended purpose)

How can this be resolved?
