I'm not sure of the state of 6.0, but thought I would give it a go. Build for iOS simulator failed, but build for device succeeded. However, there is a new requirement now apparently for a provisioning profile that enables keychain sharing? I got a message about that.
I don't see any way to enable keychain sharing though on the Apple developer portal when I set up the App ID. Maybe they use a different terminology on the portal?
As well, Apple now strongly discourages "old style" manual provisioning. But I do not want to have to create an XCode project and then go in and change the XCode project manually to do automatic provisioning.
As well, I'm afraid that I'm having the usual problem where XCode doesn't show any of my provisioning profiles. But I know where to look in the filesystem, and just assume the most recently-dated one is the one I just downloaded and installed.
Is there going to be some update to the documentation showing how to codesign the "new way"? Or is it even possible? I'm afraid that on the next XCode update they will remove old style manual provisioning all together.
BTW, Apple also now moved the display of provisioning profiles in XCode 8.3.2. Now you have to have a project open! They are making it as hard to find as possible.
I usually figure out which provisioning profile is which by downloading them one at a time, and then looking for the latest timestamp in /Library/MobileDevice/Provisioning Profiles. Then I can get the UUID from the file name.
