ios https incommunicado: Installing PEM certificate I have a test website that ios can't communicate to cause certificate is predictably trash.
I have clicked on lock icon in browser url and have extracted pem chain of cerificates
for that site.
How could I install it into keychain on macos simulator or ios device to
have that https connection trusted? (for testing purposes)
When attempting to drag and drop pem into simulator window:
AirDrop profiles and certificates to iOS works in general.
If the file you send isn’t accepted you might have to prepare a proper configuration profile and sign that to embed arbitrary unsigned or self-signed certs.
