During a security presentation at Apple’s Worldwide Developers’ Conference 2016, Apple announced that App Transport Security (ATS) will be required for all iOS apps as of 1 January 2017.
ATS enforces best practices for secure network connections, notably TLS 1.2 and perfect forward secrecy (PFS).
More information about Apple's requirements for ATS can be found here.
There are two primary areas of impact if no action is taken:

To check whether your site will be impacted by ATS, Appian is providing a preview release of the iOS App that has ATS enabled for testing purposes. In order to download the preview App, please contact Appian Technical Support either through support case or at firstname.lastname@example.org.
On a Mac running Mac OSX 10.11 El Capitan or later, you can test your site’s complaince with Apple’s ATS standards by running the command:
nscurl --verbose --ats-diagnostics <your_site_url>
The output of this command will inform you which ATS specifications, if any, your site is violating.
All public versions of the Appian app for iOS distributed after 1 January 2017 will have ATS enabled. Please ensure that your infrastructure complies with Apple’s guidelines for ATS so that your sites and applications are not affected by this change.
For customers using custom branded Appian iOS mobile applications, any applications distributed on or before 31 December 2016 will be unaffected. However, ATS must be enabled for Apps that are distributed post 1 January 2017.
If you have any additional questions, please contact Appian Technical Support either through support case or at email@example.com.
