Can I use iTunes File Sharing to add file to Transmit and Coda?
Currently iTunes file sharing can only be used to add ssh keys to Prompt, Coda, and Transmit.
This is due to iOS restrictions which require separate storage containers for Extensions and iTunes File Sharing. In the future if it’s possible to access both containers simultaneously we’ll add this to Transmit and Coda.
In the meantime you can still add files to Transmit and Coda by connecting directly to your computer the same way you would a remote server.
