iOS 10.3: Simulador HTTPS localhost: Error SSL
Esto funcionó bien para iOS 10.2 e inferior, pero después de actualizar a 10.3, cuando el simulador intenta conectarse a través de HTTPS al servidor de desarrollo que se ejecuta en localhost, la consola Xcode genera los siguientes errores:
NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802)
[] nw_coretls_callback_handshake_message_block_invoke_3 tls_handshake_continue: [-9807]
Imprimir elerror devuelto por elURLSessionDataTask muestra:

Para crear un certificado SSL autofirmado, utilicé los siguientes comandos:
openssl genrsa -aes256 -passout pass:x -out server.pass.key 2048
openssl rsa -passin pass:x -in server.pass.key -out server.key
rm server.pass.key
openssl req -new -sha256 -key server.key -out server.csr -subj /CN=localhost
openssl x509 -req -sha512 -days 365 -in server.csr -signkey server.key -out server.crt
