ios9 app transport security issues different in simulator and device

Question

upon running my app in ios9 simulator, i get app transport security related issues because some of my urls are not using https. I tried it in an ipad with ios9 and its working fine.

Upon release of ios9, should I expect my live app (sdk 8) to fail on ios9 devices? Just making sure if late appstore updates are safe.

Thanks!

Answer 1

Reference

If you're developing a new app, you should use HTTPS exclusively. If you have an existing app, you should use HTTPS as much as you can right now, and create a plan for migrating the rest of your app as soon as possible. In addition, your communication through higher-level APIs needs to be encrypted using TLS version 1.2 with forward secrecy. If you try to make a connection that doesn't follow this requirement, an error is thrown. If your app needs to make a request to an insecure domain, you have to specify this domain in your app's Info.plist file.
