Reachability doesn't detect reconnection in iOS 10 Simulator

[borneadmin]

Greetings, I'm using Reachability installed using CocoaPods with version:

• ReachabilitySwift (3) When using Reachability in iOS 10 Simulator, disconnection is normally detected (I'm doing that by turning WiFi off on my mac), but reconnection isn't detected anymore. Still works normally in iOS 9.3 simulator and it works normally on iOS 10 devices.

Might be worth checking out. It's useful for detecting UI changes based on connection status without having to install on a real device.

Thanks for this great library.

Hi all - apologies for not responding to this issue. If anyone has any time to investigate and raise a PR with a fix that would be much appreciated - or raise a bug with Apple if this looks like an iOS bug.

Cheers Ash

Ok, I’ll check tonight, hoping to find the issue ;)

I’ll fork the repo!

[babac87]

@bellots have you find out what causes the problem?

[bellots]

@babac87 unfortunately not yet... are you looking for the problem too?

[babac87]

Haven't look yet. I'll try next week to debug.

[ogezue]

is the reason for this still unknown?

[babac87]

I believe it's bug only in simulator. On the actual device all works fine.

[ogezue]

Yes I can confirm this - Thank you. I suggest to close this issue and do a remark in the readme.md

[ashleymills]

@ogezue @babac87 Thank you - I'll do that

I thought this issue affects simulator only. Unfortunately I was also able to replicate this problem on a device. I tried turning flight mode on and off. Tried to do that 30 times. Most of the time it worked as expected. But 3 out of 30 times the connection change was NOT registered by the framework.

I found that the problem is waaay more prominent when checking host reachability (using init?(hostname: String) convenience initialiser. When we are just checking for internet connection (using init?()) it works much more reliable, even on simulator.

You can use the code for simulator.

var isRunningOnDevice: Bool = {
    #if targetEnvironment(simulator)
    return false
    #else
    return true
    #endif
}()

Same issue here, on simulator and real device. xCode 10.2.1 iOS 12.1 & 12.2

Installed by cocoapods, release version 4.3.1.

Any update to this issue? Thanks.

Having exactly the same issue. Only for simulator (running iOS 12.2 on an iPad simulator)

[ptejas26]

Facing same issue on both device and simulator. Xcode 10.2.1

I think this is a problem with simulator because I'm using nwpathmonitor to check connection and I have the same problem. (iOS 13.0 on iphone 11 pro max)

[hs-abekert]

The same here. Checked both the new NWPathMonitor and old SCNetworkReachability.
