Apple Local Push Connectivity with error nil? - ios

Question

I'm trying to configure Local Push Connectivity. I already have Local Push Entitlement, and have install a provisioning profile with local push entitlement. It's build fine but when app start, PushProvider didn't active and start and Push Manager show error nil. I have done every instructions that sample code have provided.
This is my project.
In my application target, I have a bundle id com.my_team_name.my_app_name
and in the app group name group.com.my_team_name.my_app_name
In the .entitlement, I've set the required configuration:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.developer.networking.networkextension</key>
<array>
<string>app-push-provider</string>
</array>
<key>com.apple.developer.networking.wifi-info</key>
<true/>
<key>com.apple.security.application-groups</key>
<array>
<string>group.com.my_team_name.my_app_name</string>
</array>
</dict>
</plist>
Info.plist has noting to change
And I have a PushManager Class with this code
class AppPushManager: NSObject, NEAppPushDelegate{
func appPushManager(_ manager: NEAppPushManager, didReceiveIncomingCallWithUserInfo userInfo: [AnyHashable : Any] = [:]) {
}
static let shared = AppPushManager()
private var pushManager: NEAppPushManager = NEAppPushManager()
private let pushManagerDescription = "PushDefaultConfiguration"
private let pushProviderBundleIdentifier = "com.my_team_name.my_app_name.PushProvider"
func initialize() {
if pushManager.delegate == nil {
pushManager.delegate = self
}
pushManager.localizedDescription = pushManagerDescription
pushManager.providerBundleIdentifier = pushProviderBundleIdentifier
pushManager.isEnabled = true
pushManager.providerConfiguration = [
"host": "my_server.local"
]
pushManager.matchSSIDs = ["my_wifi_ssid"]
pushManager.saveToPreferences(completionHandler: { error in
print("error? \(String(describing: error))")
print("is active: \(pushManager.isActive)")
})
}
}
In my extension, A PushProvider Target. I have a bundle id com.my_team_name.my_app_name.PushProvider
and in the app group name group.com.my_team_name.my_app_name
In the Info.plist of my extension, I've added the required configuration:
<key>NSExtension</key>
<dict>
<key>NSExtensionPointIdentifier</key>
<string>com.apple.networkextension.app-push</string>
<key>NSExtensionPrincipalClass</key>
<string>$(PRODUCT_MODULE_NAME).PushProvider</string>
</dict>
the .entitlement file have the same contents as the application.
and I have created the extension class "PushProvider.swift" as follow:
class PushProvider: NEAppPushProvider {
...
}
When I run the application, I got this printed out
error? nil
is active: false
I think it might be something with providerBundleIdentifier in Push Manager. Have anyone know what I've missing?
