Ionic V4 - How do you align text to left in ion-button

i solve by my self its angular 7 update
angular 7 encapsulate css so if you want to override default class encapsulate css you need do just add /deep/ before class

/deep/ .swiper-wrapper {
  height: unset !important;

that’s it


Thanks, that’s good to know!
