Swift SDK

Alcove 为 Aptos 构建了 Swift SDK，见此处。

安装 Swift SDK

.package(url: "https://github.com/ALCOVE-LAB/aptos-swift-sdk.git", branch: "main")

使用 Swift SDK

创建客户端

可以导入 aptos-swift-sdk 并创建 Client：

import Aptos

let client = Aptos(aptosConfig: .devnet)

可通过 AptosConfig.Network 配置网络，或使用已有的 AptosConfig.devnet、AptosConfig.testnet 或 AptosConfig.mainnet。

创建私钥

可调用 Account.generate() 创建新的 Ed25519 账户私钥。

let account = Account.generate()

从私钥派生：

let privateKey = try Ed25519PrivateKey("myEd25519privatekeystring")
// or
let singleKeyPrivateKey = try Secp256k1PrivateKey(Secp256k1.privateKey)

let newAccount: Account.Ed25519Account = try Account.fromPrivateKey(privateKey)
let singleKeyAccount: Account.SingleKeyAccount = try Account.fromPrivateKey(singleKeyPrivateKey)

从路径派生：

let path = "m/44'/637'/0'/0'/1"
let mnemonic = "various float stumble..."
let newAccount = try Account.fromDerivationPath(Wallet.path, mnemonic: Wallet.mnemonic)

为账户注资

可通过 Devnet faucet 创建并注资账户：

let account = Account.generate()
let txn = try await client.faucet.fundAccount(accountAddress: account.accountAddress, amount: 100_000_000)

在 Testnet 上，可以在铸造页面领取代币。

发送交易

可以通过交易发送 AptosCoin：

let txn: TransactionResponse
let senderAccount = Account.generate()
_ = try await aptos.faucet.fundAccount(accountAddress: senderAccount.accountAddress, amount: 100_000_000)
let bob = Account.generate()
// Build transaction
let rawTxn = try await aptos.transaction.build.simple(
    sender: senderAccount.accountAddress,
    data: InputEntryFunctionData(
        function: "0x1::aptos_account::transfer",
        functionArguments: [bob.accountAddress, 100]
    )
)
// Sign
let authenticator = try await aptos.transaction.sign.transaction(
    signer: senderAccount,
    transaction: rawTxn
)
// Submit
let response = try await aptos.transaction.submit.simple(
    transaction: rawTxn,
    senderAuthenticator: authenticator
)
// Wait
txn = try await aptos.transaction.waitForTransaction(transactionHash: response.hash)
// Read
let transaction = try await aptos.transaction.getTransactionByHash(txn.hash)

测试

要运行 SDK 测试，只需在该仓库根目录执行：

注意：为获得更好体验，请确保没有 aptos 本地节点进程正在运行（可检查端口 8080 上是否有进程）。
