Xcode - Trying to add Self Signed Certificate (Not Verified)

Question

Hello everyone,

I'm new as iOS developper, and I'm facing a WebSocket error due to my certificate...

Error Name : errSSLXCertChainInvalid Error Code : -9807

I have a server on a device, on which I want to start a secure WebSocket communication (wss://10.0.1.1:8080/). The server has my certificate .pem and works very well with my android App. When I choose Debug in Xcode buildConfiguration, there is no problem for the WebSocket communication (I think Debug doesn't check certificate during the Handshake process). But when I choose Release, I have the error because I didn't add the certificate on the iOS App. I don't really know how to add it properly...

But, I also tried to disable HTTPS checks (ATS) :

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

but that din't work either.

If anyone can help me?

Thank you

Answer 1

What API are you using for WebSocket? NSURLSession? Network framework? Or perhaps you’re doing this from within Safari? Or a web view?

Hi,

I'm using the WebSocket from react native framework => https://reactnative.dev/docs/network#websocket-support I don't really know if that call NSURLSession or Network framework ...

To better understand, why when I choose "Debug" build configuration, ssl cert verification seems to be disabled => The connection works

But when I choose "Release" build configuration, ssl cert verification seems to be enabled => The connection doesn't work

Can you tell me how to disable ssl cert verification when I choose "Release" to do my first test?

Thank you
