  支持填充中间完成请求
• Handles error responses with detailed error descriptions and recovery suggestions.
  使用详细的错误描述和恢复建议处理错误响应。
• streaming responses both for chat completion and as well fill in the middle responses
  用于聊天完成的流式处理响应，以及填充中间响应
• Built-in support for different models and advanced parameters
  内置对不同模型和高级参数的支持
• User balance fetchin and available LLM models fetching
  用户余额获取和可用LLM模型获取
• Uses Swift concurrency (async/await) for network calls
  使用 Swift 并发 （async/await） 进行网络调用

三、Installation 安装

To integrate DeepSwiftSeek into your project, you can use Swift Package Manager (SPM):
要集成到 DeepSwiftSeek 您的项目中，您可以使用 Swift Package Manager （SPM）：

let package = Package(dependencies: [.package(url: "https://github.com/tornikegomareli/DeepSwiftSeek.git", exact: "0.0.2")]
)

Or add it via Xcode:
或通过 Xcode 添加它：

1. Open your project in Xcode.
   在 Xcode 中打开您的项目。
2. Navigate to File > Swift Packages > Add Package Dependency.
   导航到 File > Swift Packages > Add Package Dependency。
3. Enter the repository URL.
   输入存储库 URL。
4. Choose the latest version and click Next.
   选择最新版本，然后单击 Next（下一步）。

Usage 用法

1. Initialize the Client 1. 初始化客户端

import DeepSwiftSeeklet configuration = Configuration(apiKey: "YOUR_API_KEY")
let deepSeekClient = DeepSeekClient(configuration: configuration)

2. Sending a Chat Completion Request
2. 发送聊天完成请求

Task {do {let response = try await deepSeekClient.chatCompletions(messages: {ChatMessageRequest(role: .user, content: "Tell me a joke.", name: "User")},model: .deepSeekChat,parameters: .creative)print(response.choices.first?.message.content ?? "No response")} catch {print("Error: \(error.localizedDescription)")}
}

3. Streaming Chat Completions
3. 流式聊天完成

Task {do {let stream = try await deepSeekClient.chatCompletionStream(messages: {ChatMessageRequest(role: .user, content: "Write a poem.", name: "User")},model: .deepSeekChat,parameters: .streaming)for try await chunk in stream {print(chunk) // Prints streamed responses}} catch {print("Streaming error: \(error.localizedDescription)")}
}

4. Streaming FIM Completion
4. 流式 FIM 完成

Task {do {let stream = try await deepSeekClient.fimCompletionStream(messages: {[ChatMessageRequest(role: .user,content: "function greet() {\n  /* FIM_START */\n  /* FIM_END */\n  return 'Hello world';\n}",name: "User")]},model: .deepSeekReasoner,parameters: .streaming)for try await chunk in stream {// Each chunk is a streamed part of the fill-in-the-middle response.print("FIM Stream Chunk:\n\(chunk)")}} catch {print("FIM Streaming Error: \(error.localizedDescription)")}
}

5. Sending FIM Completion Request
5. 发送 FIM 完成请求

Task {do {let response = try await deepSeekClient.fimCompletions(messages: {[ChatMessageRequest(role: .user,content: "function greet() {\n  // FIM_START\n  // FIM_END\n  return 'Hello world';\n}",name: "User")]},model: .deepSeekReasoner,parameters: .creative)if let content = response.choices.first?.message.content {print("FIM Completion:\n\(content)")}} catch {print("FIM Error: \(error.localizedDescription)")}
}

6. Getting List of Models
6. 获取模型列表

Task {do {let response = try await deepSeekClient.listModels()} catch {print("ListModels Error: \(error.localizedDescription)")}
}

7. Getting Balance of the user
7. 获取用户的余额

Task {do {let response = try await deepSeekClient.fetchUserBalance()} catch {print("UserBalance Error: \(error.localizedDescription)")}
}

8. Handling Errors 8. 处理错误

The SDK provides detailed error handling:
SDK 提供了详细的错误处理：

catch let error as DeepSeekError {print("DeepSeek API Error: \(error.localizedDescription)")print("Recovery Suggestion: \(error.recoverySuggestion ?? "None")")
} catch {print("Unexpected error: \(error)")
}

四、Models 模型

DeepSeek SDK supports multiple models:
DeepSeek SDK 支持多种模型：

public enum DeepSeekModel: String {case deepSeekChat = "deepseek-chat"case deepSeekReasoner = "deepseek-reasoner"
}

Available Parameters 可用参数

You can configure chat completion parameters:
您可以配置聊天完成参数：

let parameters = ChatParameters(frequencyPenalty: 0.5,maxTokens: 512,presencePenalty: 0.5,temperature: 0.7,topP: 0.9
)

Predefined Parameter Sets
预定义参数集

Mode 模式	Temperature 温度	Max Tokens 最大令牌数	Top P 前 P
Creative 创造性	0.9	2048	0.9
Focused 集中	0.3	2048	0.3
Streaming 流	0.7	4096	0.9
Code Generation 代码生成	0.2	2048	0.95
Concise 简明	0.5	256	0.5

Creating Custom Predefined Parameters
创建自定义预定义参数

If you need specific configurations, you can define your own parameter presets:
如果您需要特定配置，您可以定义自己的参数预设：

extension ChatParameters {static let myCustomPreset = ChatParameters(frequencyPenalty: 0.4,maxTokens: 1024,presencePenalty: 0.6,temperature: 0.8,topP: 0.85)
}

Then use it in your requests:
然后在您的请求中使用它：

let parameters = ChatParameters.myCustomPreset

This approach allows you to maintain reusable configurations tailored to different needs.
此方法允许您维护针对不同需求量身定制的可重用配置。

Error Handling 错误处理

DeepSeek SDK has built-in error handling for various API failures:
DeepSeek SDK 内置了针对各种 API 故障的错误处理功能：

Error Type 错误类型	Description 描述
invalidFormat	Invalid request body format. 请求正文格式无效。
authenticationFailed	Incorrect API key. API 密钥不正确。
insufficientBalance	No balance remaining. 没有余额。
rateLimitReached	Too many requests sent. 发送的请求过多。
serverOverloaded	High traffic on server. 服务器上的高流量。
encodingError	Failed to encode request body. 无法对请求正文进行编码。
