Hi!

As you can see, APE is basically EOL/Dead (See 
https://github.com/APE-Project/APE_Server/issues/58). You might get some 
support here, but no new version should be expected.

That being said, I don’t think your problem comes from APE, but from how iOS 
handle stuff.  You can’t keep something running on Safari (either the browser 
and in app web view) forever. Otherwise, you would consume most of the device 
ressources (Data & battery life) in background for nothing. There’s a complex 
way in iOS apps to do that (which I’m not a specialist of). Long story short, 
that’s why safari close the connexion to APE when in background for too long. 
From what I experienced, I would say it keeps everything alive for 30-60 secs. 
After that, background management stuff is needed. 

In your example, you probably have an outdated users list when you come back, 
that’s why you can see the « connected » users (new users probably don’t 
appear).


The best way to work around this in APE (or other socket type thingy) is to 
detect when the app closes/go to background (window.onunload in JS or something 
like applicationDidEnterBackground & applicationWillEnterForeground in your 
AppDelegate on iOS native), tell the server to hold on to the message it need 
to send to you and close the connexion. When you come back, you get from the 
server what happened while you where away and restore the connexion. While in 
background, Apple Push Notification (APN) should be used from the [APE] server 
to notify the user (way more simple and efficient).

Again, depending of what exactly you want to do with APE on iOS, APN would 
probably be way some simple to use than an APE solution. The only advantage I 
see to using APE (or other socket type connection) in an iOS app is if the 
volume of notification/data being sent (request per second) is really high. For 
low volume, it’s much easier to stick to APN / NSMutableURLRequest.

If you really want to go the APE way on iOS, you can also check this native 
Client I wrote a couples of years ago: 
https://github.com/lcharette/APE_iOS_Client
It’s very experimental and has never been tested on a real life App Store 
available app (My App got rejected for unrelated reasons before I could 
implement APE in it), but you will get a global ideas on how it works.
