Firebase plugin error: Could not find TLS Provider: `Mono.AppleTls.AppleTlsProvider'.

Hi :slight_smile:
After building a unity firebase project to iOS and trying to get a record (async) I get the following exception:
"System.NotSupportedException: TLS Support not available. —> System.NotSupportedException: Could not find TLS Provider: `Mono.AppleTls.AppleTlsProvider’.
at Mono.Net.Security.MonoTlsProviderFactory.LookupProviderType (System.String name, System.Boolean throwOnError) [0x00000] in <00000000000000000000000000000000>:0 "

I also tried this with a test project - one that includes the plugin and a simple script that connects to the database and retrieves a record. The exception occurs when trying to retrieve the record
Also, I added the plist file, installed cocoa pods and have the latest plugin.

I’m using:
Unity version: 2017.2.0f3
xcode version : 9.1
Firebase sdk: 4.4.0
.net 4.6

The project works correctly in Android by the way.
This is very urgent to me, we have an upcoming release…

Thanks :slight_smile:
