Hi,
I try to create a socket client to connect to a server, and get/send data as well. My code as below, it connected successfully to the server, but I don't how to receive /send data. Can somebody help me out of this?
import Foundation
import CoreFoundation
class SocketClient {
private(set) var host: String
private(set) var port: Int
private var socket: CFSocket?
init(_ host:String, _ port: Int){
self.host = host
self.port = port
}
func connect(){
//create socket
self.socket = CFSocketCreate(kCFAllocatorDefault, PF_INET, SOCK_STREAM, IPPROTO_TCP, CFSocketCallBackType.dataCallBack.rawValue, {
socket, callBackType, address, data, info in
if CFSocketCallBackType.dataCallBack == callBackType && data != nil {
debugPrint("incomming。。。")
}
}, nil)
guard self.socket != nil else{
debugPrint("create socket failed")
return
}
//binding ip
var address: sockaddr_in = sockaddr_in()
address.sin_family = sa_family_t(PF_INET)
address.sin_port = in_port_t(self.port)
var inAddr = in_addr()
inAddr.s_addr = inet_addr(self.host)
address.sin_addr = inAddr
let addrData = CFDataCreate(kCFAllocatorDefault, &address, MemoryLayout.size(ofValue: address))
let result = CFSocketConnectToAddress(self.socket, addrData, 5)
if result == .success {
debugPrint("connect succeed")
} else {
debugPrint("connect failed")
}
let source = CFSocketCreateRunLoopSource(kCFAllocatorDefault, self.socket, 1)
CFRunLoopAddSource(CFRunLoopGetCurrent(), source, .commonModes)
}
}

After I installed xcode13 and updated pods of my swiftui project by executing pod update, it occurred an unexpected compile error when I tried to run my project.
Cannot assign value of type '()' to type 'DispatchSourceTimer?'
Is this a new bug? or I did something wrong? See my code below:
//use case for counting down time
self.timer = DispatchSource.dispatchTimer(timeInterval: 1, handler: { dispatchTimer in
self.time -= 1
if self.time < 0 {
dispatchTimer?.cancel()
self.next()
}
}, needRepeat: true)
//DispatchSource extension function
public extension DispatchSource {
class func dispatchTimer(timeInterval: Double, handler: @escaping (DispatchSourceTimer?) -> Void, needRepeat: Bool) {
let timer = DispatchSource.makeTimerSource(flags: [], queue: DispatchQueue.main)
timer.schedule(deadline: .now(), repeating: timeInterval)
timer.setEventHandler {
DispatchQueue.main.async {
if needRepeat {
handler(timer)
} else {
timer.cancel()
handler(nil)
}
}
}
timer.resume()
}
}
Please help!

hi guys, I try to write a ApiRequest class to handle common request settings and response data, here is a delete function I wrote below:
public static func delete<Parameters: Encodable>(_ convertible: URLConvertible, parameters: Parameters? = nil, success: @escaping (Data?)->Void, failure: @escaping (ApiError)->Void) {
debugPrint("ApiRequest.delete->")
debugPrint(convertible)
debugPrint("parameter-> \(parameters)")
AF.request(convertible, method: .delete, parameters: parameters).response{ response in
handleResponse(response, success: success, failure: failure)
}
}
I used an optional type-inferred parameter here. I got "Generic parameter 'Parameters' could not be inferred" error when I call this function without parameters:
ApiRequest.delete("\(WorkoutApi.routine_delete.rawValue)/\(id)",success: {response in
let index = self.routineList.firstIndex(where: { routine in
routine.id == id
})
if index != nil {
withAnimation(.spring()){
self.routineList.remove(at: index!)
}
}
}, failure: {error in
})
Somebody please help me!! How can I get this code right.Waiting online
