Q:

X.iOS Cycle7 seems to break SSL

Yesterday I updated XS to the RC version in the Beta-channel, to cycle7.
Now I'm experiencing problems when connecting to HTTPS-connections with iOS, error:
Error: SecureChannelFailure (The authentication or decryption has failed.)

I'm using Refit for API communications.
Connection is made to CloudFlare on a valid HTTPS certificate.
The current app, which is build in the previous cycle, is still working fine.
I haven't changed anything at the code, which is working for months.
I've tried to use the new "Apple TLS" implementation for SSL, which solved a bit, but gives me SSL issues when uploading an image.
I'm not 100% sure if I already should file a bug-report.
Anyone could give me some tips on what I could try? Or should I directly file a bug-report?

A:

This exception only happens when you have the "Xamarin Inspector" add-in enabled.
As Sebastian here said here It's probably 'swapping assemblies'.
The solution is to disable the add-in in the Add-in manager of XS. After that the exception won't occur anymore.
