如何判断助记词 keystore 私钥是否正确

[caiyanzhong]

当输入错误的助记词之后，不抛出异常 直接导入成功
public static func importFromMnemonic(_ mnemonic: String, metadata: WalletMeta, encryptBy password: String, at path: String) throws -> BasicWallet {
let identity = try IdentityValidator().validate()
return try identity.importFromMnemonic(mnemonic, metadata: metadata, encryptBy: password, at: path)
}

抛出的异常是不是应该用MnemonicValidator
