A client for the Ethereum Whisper communication protocol, written in Swift.
Shhwift currently requires a running Ethereum node with Whisper enabled on the JSON-RPC interface. For instance, by running Ethereum Go with the following parameters:
geth --shh --rpc --rpcapi "shh"
The default Ethereum boot nodes currently do not run Whisper. This means that you won't be able to participate in the Whisper peer-to-peer network, unless you explicitly use a Whisper node as bootnode.
You can run such a bootnode yourself by running geth --shh and use the enode url that it prints upon startup as the bootnode argument for the other nodes:
geth --shh --rpc --rpcapi "shh" --bootnodes enode://<public key>@<ip address>:30303
