title: Update iOS 11 App icons in assets.car post build
body: <p>I currently have an iOS project where I create a ipa with one set of app icons and then what I do ,post building in Xcode ,is unzip the ipa via a sh script copy some new app icons to the root level of the .app file ,change the app ID and resign it and this all works great until iOS 11 came along and I notice it would like for the icons to be in the assets.car file.</p>
  
  <p>Does anyone know if it’s possible to update that assets.car file post build ,via a sh ideally ,with a new set of app icons without having to rebuild the project </p>
  
  <p>Thanks in advance </p>
