Any plan to support the watchOS as well in the near future?
I was having an issue with the event source disconnecting at regular intervals and determined that it was because the underlying NSURLRequest hadn't had its timeoutInterval set. After changing [NSURLRequest requestWithURL:] to [NSURLRequest requestWithURL: cachePolicy: timeoutInterval:], the connection stays open as expected. Perhaps it would make sense to change [EventSource initWithURL:] to [EventSource initWithURL: timeoutInterval:]?
Can you please update pod spec into 1.0.4 ?
It's trying to download 1.0.2.
I am building IOS application using firebase REST API. From the doc (Ref: https://firebase.google.com/docs/reference/rest/database/) it says that we can Stream from the REST API.I am not able to listen firebase events.When I run the app Only onOpen callback is called. When i changed the child value on firebase nothing happened on callback methods. Can you suggest me the way to observe the events?
I tried the following code:
Auth.auth().currentUser?.getIDTokenForcingRefresh(true, completion: { (token, error) in
let server : String = "https://project-XXXXX.firebaseio.com/.json?auth=\(token!)"
let eventSource: EventSource = EventSource(url: server)
eventSource.onOpen {
// When opened
debugPrint("eventSource open")
}
eventSource.onError { (error) in
// When errors
debugPrint("error = \(error?.localizedDescription)")
}
eventSource.onMessage { (id, event, data) in
debugPrint("data = \(data)")
// Here you get an event without event name!
}
eventSource.addEventListener("child_added") { (id, event, data) in
debugPrint("data = \(data)")
// Here you get an event 'event-name'
}
})

My server returns data in single line. But if it is very large (a few dozen screens if use line-breaks, I may measure if needed), looks like URLSession calls didReceiveData with parts of payload. I found it here. So payload just comes broken.
When I am trying to access the event source , I am getting the json breaking or not receiving proper json.
If server send a lot of event handler will not get call, it will stuck on first for loop. Here is my hot-fix code.
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
__block NSString *eventString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
if ([eventString hasSuffix:@"\n\n"]) {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{
NSArray* eventArray = [eventString componentsSeparatedByString:@"\n\n"];
for (NSString* sigleEventString in eventArray) {
NSArray *components = [sigleEventString componentsSeparatedByString:@"\n"] ;
Event *e = [Event new];
e.readyState = kEventStateOpen;
for (NSString *component in components) {
NSUInteger location = [component rangeOfString:@":"].location;
if (location != NSNotFound) {
NSString *dataPath = [component substringFromIndex:location+1];
dataPath = [dataPath stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if ([component hasPrefix:@"id:"]) {
e.id = dataPath;
} else if ([component hasPrefix:@"event:"]) {
e.event = dataPath;
} else if ([component hasPrefix:@"data:"]) {
e.data = dataPath;
}
}
}
if (e.event != nil) {
NSArray *namedEventhandlers = listeners[e.event];
for (EventSourceEventHandler handler in namedEventhandlers) {
dispatch_async(dispatch_get_main_queue(), ^{
handler(e);
});
}
}
}
});
}
}
Thanks for your good library. EventSource has memory leak issue.
I read this post in stackoverflow.

Can you please check it and update library ?
Hi,
If I attempt to connect to a stream which I know will fail (Incorrect auth) the onError:
method is called.
In this method I call [self.source close];
however I keep receiving onError:
callbacks as if it's still trying to connect.
Calling [self.source close];
should surely stop any attempts to reconnect?
Calling [self.source close];
on any connections that are open, successfully closes them.
