TDLibFramework

Project contains pre-compiled TDLib binary for iOS, macOS, watchOS, tvOS and simulators in .xcframework bundle.

If you're looking for pure Swift library, check out TDLibKit

Installation

Xcode (SPM)

Install latest Xcode
Add https://github.com/Swiftgram/TDLibFramework as SPM dependency in Project > Swift Packages. This could take a while cause it downloads ~300mb zip file with xcframework.
Add TDLibFramework as your target dependency.
Code!

Cocoapods & Flutter

See Wiki page

Usage

Create client

let client: UnsafeMutableRawPointer! = td_json_client_create()

Make request object

let request = ["@type": "getTextEntities", "text": "@telegram /test_command https://telegram.org telegram.me", "@extra": ["5", 7.0, "\\u00e4"]] as [String: Any]

JSON Serialization and Deserialization

Small example for helper functions you will need to talk with TDLib

func dictToJSONString(_ dictionary: [String: Any]) -> String {
    let dictionaryData = try! JSONSerialization.data(withJSONObject: dictionary)
    return String(data: dictionaryData, encoding: .utf8)!
}

func JSONStringToDict(_ string: String) -> [String: Any] {
    let responseData = string.data(using: .utf8)!
    return try! JSONSerialization.jsonObject(with: responseData, options: .allowFragments) as! [String: Any]
}

Synchronious requests

Only for methods with "Can be called synchronously" in docs

if let res = td_json_client_execute(client, dictToJSONString(request)) {
    let responseString = String(cString: res)
    let responseDict = JSONStringToDict(responseString)
    print("Response from TDLib \(responseDict)")
}

Async requests

let request = ["@type": "setTdlibParameters",
                "parameters": [
                    "database_directory": "tdlib",
                    "use_message_database": true,
                    "use_secret_chats": true,
                    "api_id": 94575,
                    "api_hash": "a3406de8d171bb422bb6ddf3bbd800e2",
                    "system_language_code": "en",
                    "device_model": "Desktop",
                    "application_version": "1.0",
                    "enable_storage_optimizer": true
                    ]
                ] as [String : Any]

// Send request
td_json_client_send(client, dictToJSONString(request))

// Block thread and wait for response (not more 5.0 seconds)
if let response = td_json_client_receive(client, 5.0) {
   let responseString = String(cString: res)
   let responseDict = JSONStringToDict(responseString)
   print("Async response from TDLib \(responseDict)")
}

Destroy client on exit

td_json_client_destroy(client)
