Assets are almost always the main culprit of large apps sizes.

If you archive your app and export the IPA you will be able to convert it so a .zip by changing the extension and then unzip and look at the contents of the package.

If you sort by file size you will see which files are the largest. Keep in mind images with transparency are larger.
