Hi,
this is How we managed to go around this issue:Have your certificate(s) available through a web link for download
Copy/paste link in Safari on the Simulator
The Certs will be copied/downloaded to the Simulator (Allow your Certs.)
On the the Simulator, go to General -> About -> Certificate Trust Settings -> “Enable Full Trust for Root Certificate” for your particular certificate
You need to repeat this for EVERY certificate needed.
Thanks to Nish Abe for part of this fix!
Hope this helps
