App Transport Security, Xcode 7.1 & iOS 9.1

Yes having similar issue.
First, i thought something is wrong with plist file, but after checking for a hundred times - i cannot agree more.

Xcode overrides any configurations you add regarding the NSAppTransportSecurity.

Looking forward to any advices here.

(note some of the previous names for keys have changed!!)

The key changes are just Xcode being ‘helpful’ and showing you user-friendly values. Personally I prefer to use raw values, which you can get by choosing Editor > Show Raws Keys & Values.

Testing this on iPhone simulator under iOS 8 works fine.

Huh? ATS was only implemented in iOS 9, so you’d expect things to always work in iOS 8.

AFAIK there’s been no substantial ATS policy changes in iOS 9.1 vs iOS 9.0. Have you tried your app on iOS 9.0.x to see how it behaves there?

I am also facing the same Issue. I am using XCode 7.1 on OS X El Capitan.

I have used the changed key "App Transport Securtiy Settings" in info.plist file. But still I am getting the same error.

I have checked it for tvOS. with beta version it was working fine but in XCode 7.1 it is not working.

Hi,

I saw a simular problem. I had both the NSExceptionDomains & NSAllowsArbitraryLoads keys in my plist, and all URL calls were failing. I removed the NSExceptionDomains key, and kept the NSAllowsArbitraryLoads key, and it started working again (Xcode 7.1 and iOS 9.1 simulator).

Trust me folks, ATS is working just fine in iOS 9.1 and OS X 10.11, regardless of whether you use Xcode 7.0 or 7.1. If you’re having ATS problems, it’s very likely that’s because ATS is not happy with your server. If the

Info.plist

I can sympathise here. This stuff is super tricky. Moreover, some folks have actually encountered oddities in ATS, or other problems that look like ATS bugs because they affect TLS connections in non-obvious ways. However, my experience so far is that the majority of ATS issues are caused by folks configuring ATS incorrectly (with the underlying cause being, of course, that our documentation and diagnostics are not exactly stellar).

Rather than piling on this thread I recommend that each of your who is having a problem with ATS start a new thread. Your post should include:

• the output from

  TLSTool

  , as described here

• a copy of the

  NSAppTransportSecurity

  entry from your

  Info.plist

  IMPORTANT Don’t rely on what Xcode shows you. Use a text editor to copy this out of your built binary.

• a summary of what OS releases you’ve been testing on

Can you look into why the Technote is missing? Devs have no reference anymore for ATS.

Can you look into why the Technote is missing?

The content of the technote got moved into the Information Property List Key Reference. I updated the App Transport Security post, in the Announcements sidebar, with a link.

There should be a redirect from the old ATS Technote URL to this new location but that was dropped due to a mixup at our end; I’m trying to get it resolved (r. 23097610).

I found an interesting thing, I use Xcode7 config

<key>NSAppTransportSecurity</key>

<dict>

<key>NSAllowsArbitraryLoads</key>

<true/>

</dict> ,

and then back Xcode6 development for a period of time for the same project, and finally to the Xcode7 package,test, found that the addition of the configuration is invalid, delete the configuration and then add it in Xode7 again,finally configuration plays work, I want to know why?
