A Summary of the WWDC25 Group Lab

On iOS 8 and earlier it was possible to install a custom SSL root certificate on iOS, which would allow Safari and apps to trust that certificate for the signing of secure resources accessed via HTTPS / SSL / TLS etc.On iOS 9 it is still possible to install a custom SSL root certificate, and Safari will trust it for accessing websites. However in apps compiled for iOS 9, ATS appears to reject the certificate, in spite of Safari on the same device trusting it.Are apps using their own trust store now?I am trying to use the app with Charles Proxy, so perhaps there's a different issue occuring. Disabling ATS makes it work. Adding exceptions on the TLS version and forward secrect for the specific domain do not, which is good as I believe Charles Proxy is using TLSv1.2 and ciphers that support PFS. So I am left guessing that it is rejecting the SSL certificate.I have used CFNetwork Diagnostics output to try to diagnose it, but I don't appear to gain much information.Although the log is pretty much identical with or

As I understand it, to share keychain data between a Watch app and the iOS app, you need to set up a keychain access group entitlement, and make the keychain item with the kSecAttrAccessGroup attribute and a value that matches that keychain access group entititlement.Xcode sets up an entitlement file that looks like $(AppIdentifierPrefix)some.identifier.here. In code, though, how do we get an app identifier prefix to make the matching kSecAttrAccessGroup value? Or does the kSecAttrAccessGroup value exclude the $(AppIdentifierPrefix) part of the entitlement item?

Ive been working on a script to automatically rejoin Jabber based MUC rooms from messages. This script worked flawlessly up until trying on El Cap beta. After digging around and trying some very basic functions it appears that the scripting language for Messages is broken. Here is the code that currently works in Yosemite and not in El Cap.repeat with timeout of 3600 seconds if application Messages is running then tell application System Events to tell process Messages with timeout of 3600 seconds set AllWindows to name of every window if (AllWindows contains Verify Certificate) then perform action AXRaise of (first window whose name contains Verify Certificate) click button Continue of group 2 of window Verify Certificate display notification I DID THE THING! with title Verify Certificate Alert Exterminated end if end timeout end tell tell application Messages with timeout of 3600 seconds repeat with c in text chats if connection status of service of c is connected and join state of c is not joined

Hi,Since WWDC and the developer programs have been merged in one account (OS X, iOS and Apple Watch), I can't access the beta version of iOS 9 and OS X 10.11: when I click on a link, even for a release notes, I'm redirected the login page of Apple ID, but no problem downloading iOS 8.4. Before I got a NDA signed and was able to download seed versions.BTW, if I click on Apple Developer Program License Agreement in Your Account > Account Summary > Legal Agreement, I'm redirected to the same login Apple ID page...I've tried with different browser and cookies are enabled.Thanks for your help,Daniel

Hi all,I just updated to the latest betas on my machine and mobile devices GPU frame capture crashes Xcode every time. I've restarted everything, deleted preferences, tried other devices and computers and I always get the same result. Below is the crash report. I'm hoping that there is something that I can do to resolve the issue without waiting for the next beta.Thanks,David RogersProcess: Xcode [3662]Path: /Applications/Xcode-beta.app/Contents/MacOS/XcodeIdentifier: com.apple.dt.XcodeVersion: 7.0 (8163.8)Build Info: IDEFrameworks-8163008000000000~7Code Type: X86-64 (Native)Parent Process: ???

In order for data (contained within a number of our created apps) such as user IDs, email addresses and user specific text stings to be shared between apps, we are considering saving this data to the shared container's NSUserDefaults using an app group.We would like to ask you the following question:How safe is the shared container for an App Group from a security perspective?We searched for an official Apple document, however, we were unable to find material stating clearly the safety of an app group's shared container.Below is what material we found through our investigation.- https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/WatchKitProgrammingGuide/DesigningaWatchKitApp.html#//apple_ref/doc/uid/TP40014969-CH3-SW1　Overview > WatchKit App Architecture > Sharing Data with Your Containing iOS App　An app group is a secure container that multiple processes can access.- https://www.apple.com/business/docs/iOS_Security_Guide.pdfIf there is any oth
