# TDLibKit
[](https://github.com/Swiftgram/TDLibKit/actions/workflows/ci.yml)
TDLibKit is a native Swift wrapper for [TDLib](https://github.com/tdlib/td) with support for iOS, macOS, watchOS, tvOS and visionOS.
Powered by pre-built multi-platform [TDLibFramework](https://github.com/Swiftgram/TDLibFramework) implementation
of [TDLib](https://github.com/tdlib/td) and generated sources with [tl2swift](scripts/tl2swift)
## Installation
### Xcode
1. Install Latest Xcode
2. Add `https://github.com/Swiftgram/TDLibKit` as SPM dependency in `Project > Swift Packages`. This could take a while
cause it downloads ~300mb zip file with binary
from [TDLibFramework dependency](https://github.com/Swiftgram/TDLibFramework)
3. Add `TDLibKit` as your target dependency.
4. Code!
### Cocoapods
Integration requires similar
to [TDLibFramework Cocoapods & Flutter guide](https://github.com/Swiftgram/TDLibFramework/blob/main/docs/COCOAPODS-and-FLUTTER.md)
adaptation.
## Usage
Library provides multiple API interfaces based on different approaches
- [Async/Await](https://docs.swift.org/swift-book/documentation/the-swift-programming-language/concurrency/) syntax & do/catch. Available for iOS
13.0+, macOS 10.15+, watchOS 6.0+, tvOS 13.0+, visionOS
- Completion handlers & closures
### Create client Manager
```swift
import TDLibKit
let manager = TDLibClientManager()
```
Make sure to create only one `TDLibClientManager`, since `td_receive` can be only called from a single thread.
Manager automatically polls for new updates, we will handle them per-client below.
### Create Client & Handle updates
```swift
let client = manager.createClient(updateHandler: { /* data: Data, client: TDLibCLient */
do {
let update = try $1.decoder.decode(Update.self, from: $0)
switch update {
case .updateNewMessage(let newMsg):
switch newMsg.message.content {
case .messageText(let text):
print("Text Message: \(text.text.text)")
default:
break
}
case .updateMessageEdited:
break
// ... etc
default:
print("Unhandled Update \(update)")
break
}
} catch {
print("Error in update handler \(error.localizedDescription)")
}
})
```
### Synchronious requests
Only for methods
with "[Can be called synchronously](https://github.com/tdlib/td/blob/73d8fb4b3584633b0ffde97a20bbff6602e7a5c4/td/generate/scheme/td_api.tl#L4294)"
in docs
```swift
let query = SetLogVerbosityLevel(newVerbosityLevel: 5)
do {
let result = try client.execute(query: DTO(query))
if let resultDict = result {
print("Response: \(resultDict)")
} else {
print("Empty result")
}
} catch {
print("Error in SetLogVerbosityLevel request \(error.localizedDescription)")
}
```
### Async requests
#### Async/Await
```swift
do {
let chatHistory = try await client.getChatHistory(
chatId: chatId,
fromMessageId: 0,
limit: 50,
offset: 0,
onlyLocal: false // Request remote messages from server
)
for message in chatHistory.messages {
switch message.content {
case .messageText(let text):
print(text.text.text)
case .messageAnimation:
print("")
case .messagePhoto(let photo):
print("\n\(photo.caption.text)")
case .messageSticker(let sticker):
print(sticker.sticker.emoji)
case .messageVideo(let video):
print("\n\(video.caption.text)")
// ...
default:
print("Unknown message content \(message.content)")
}
}
} catch {
print("Error in getChatHistory \(error)")
}
```
#### Completion Handlers
```swift
try? client.getChatHistory(
chatId: chatId,
fromMessageId: 0,
limit: 50,
offset: 0,
onlyLocal: false, // Request remote messages from server
completion: { result in
// Handle Errors
if case .failure(let error) = result {
print("Error in getChatHistory request \(error.localizedDescription)")
} else if let messages = try? result.get().messages {
// Handle messages
for message in messages {
switch message.content {
case .messageText(let text):
print(text.text.text)
case .messageAnimation:
print("")
case .messagePhoto(let photo):
print("\n\(photo.caption.text)")
case .messageSticker(let sticker):
print(sticker.sticker.emoji)
case .messageVideo(let video):
print("\n\(video.caption.text)")
// ...
default:
print("Unknown message content \(message.content)")
}
}
}
}
)
```
### Logging
You can pass additional parameter with `Logger` type to log "send, receive, execute" and custom entries.
```swift
import TDLibKit
public final class StdOutLogger: TDLibLogger {
let queue: DispatchQueue
public init() {
queue = DispatchQueue(label: "Logger", qos: .userInitiated)
}
public func log(_ message: String, type: LoggerMessageType?) {
queue.async {
var fisrtLine = "---------------------------"
if let type = type {
fisrtLine = ">> \(type.description): ---------------"
}
print("""
\(fisrtLine)
\(message)
---------------------------
""")
}
}
}
let manager = TDLibClientManager(logger: StdOutLogger())
```
### Close client
To ensure data integrity, you must properly close all the clients on app termination, either with
```swift
let client = manager.createClient()
try? client.close(completion: { _ in })
```
or use a blocking function
```swift
manager.closeClients()
```
