I'm facing the same issue on Ionic 2.

@chamerling I just noticed from the link you provided that the new Safari for OS X does support WebRTC. Any chance of supporting Safari now?

I believe `blob.identify_without_saving` is the root of the problem as it tries to [`find_or_build_blob`](https://github.com/rails/rails/blob/v6.1.0/activestorage/lib/active_storage/attached/changes/create_one.rb#L52) and that only accepts one of: `ActiveStorage::Blob`, `ActionDispatch::Http::UploadedFile`, `Rack::Test::UploadedFile`, `Hash` or `String`.

@yogeshjain999 yes that does work as `file.blob` returns an instance of `ActiveStorage::Blob` which is one of the supported classes.
