Code apparently has been written for this, but does not seem to be present in Rhodes 5.0.2. That is, whatever "Rhodes 5.0.2" means, since the version numbers don't seem to have much meaning of late.
It is in the git `master` branch, however.
Update: this code4 was added July 21. I have 5.0.2 dated July 7, so impossible for this to be in current version, unless "5.0.2" has been updated. Re-downloading now to compare the Gems and see if they are identical.
Verified this is not supported in current RMS 5.0.2. I'll give current `master` a try, but have some concern that it may not be stable.
Now that iOS8 is released, is it perhaps time for an incremental RMS release?
You need to build the Gem from the master branch of the repo, or at least some commit that gets you the updates for Xcode 6.
I also had some problem with my Xcode 6.0.1 installation. I had downloaded from the iOS dev site, and pretty sure it was not a "beta" that I downloaded. But I was not getting any simulators. So then I updated from the App Store, and still had trouble. I had to make darn sure that bad 6.0.1 was really, really gone - uninstall with hold down until "wiggle" (that's now how you uninstall OSX apps from the App Store - just like on your iPhone). Then move remaining Xcode.app to trash. Then delete the trash. Then reboot. Then install Xcode 6.0.1 from App Store. Otherwise, bits want to stick around, Zombies rising from the trash!
I've posted a number of Issues relating to iOS8 and Xcode 6 to the GitHub repo. There are some workaround posted there, so if you are experimenting with iOS8/XCode 6 you might want to go read those Issues.
Note that Apple has moved the location of simulator data in Xcode 6, and so currently the sim-public and rholog.txt symlinks do not work. As well, the simulator now has a separate environment for each combination of device/version, and so you can no longer just test different devices by switching the device in the iOS Simulator menu (your app won't be there) so Rhodes needs some support for targeting specific device/version environment.
You need to build current master Gem (or at least one with Xcode 6 support). BTW, builds under Ruby 2.1.3 without needed iconv Gem.
