Why develop a wallet from the scratch If there is something already open source and being updated on a regular basis? If you want an SPV wallet then you have Electrum, the iOS version is not out yet but It should be soon.
Thanks for your info,do you mean the Electrum wallet could support others coin too?
It's not quite clear what you are asking. Electrum is a Bitcoin only wallet, although it can be ported to support other currencies, and the iOS version should only be able to support Bitcoin. If they add altcoin support, they'd probably do it for the PC version first.
A SPV Server is
not a wallet. It is a server that Electrum uses to get the transactions and blockchain data from. Running an SPV server on a phone is largely pointless, as you'd need internet connection at all times for it to be useful.
If you are asking for someone to develop an SPV wallet that supports altcoins, move this to the Altcoins section.
