This PR is dependent on https://github.com/material-components/material-components-ios/pull/6035. And there is no new API change on MDCChipTextField class level. This PR is meant to solve the problem mentioned in https://github.com/material-components/material-components-ios/pull/6035 -> "Enabling scrolling of the Chips and the remaining alignment issues will be resolved in followup PRs." The issues it solves: (1) Alignment (a way to adjust it also) (2) clear button (3) the coupling issue with apple's leftView in the original PR. Screenshots:
