EthereumKit

EthereumKit is a Swift framework that enables you to create Ethereum wallet and use it in your app.

let mnemonic = Mnemonic.create()
let seed = Mnemonic.createSeed(mnemonic: mnemonic)

// BIP32: Key derivation and address generation

let wallet: Wallet
do {
    wallet = try Wallet(seed: seed, network: .main)
} catch let error {
    fatalError("Error: \(error.localizedDescription)")
}

// Send some ether
let rawTransaction = RawTransaction(ether: "0.15", to: address, gasPrice: Converter.toWei(GWei: 10), gasLimit: 21000, nonce: 0)
let tx = try wallet.signTransaction(rawTransaction)

geth.sendRawTransaction(rawTransaction: tx) { result in 
    // Do something...
}
