“build disappears”

There are a couple error messages that developers have seen when using the iOS Simulator. We can certainly do better to make these error messages less cryptic in future releases, but for now, hopefully this post will help you out. Note that this information (likely a more condensed form of it since I am quite verbose here) should appear in Xcode release notes.1) Unable to boot the iOS SimulatorThis error message will appear in iOS Simulator, and if hitting Build&Run from Xcode, you will likely get an (Domain = DTiPhoneSimulatorErrorDomain, Code = 2) error there as well. With iOS 7 and later, the simulator runtime gained its own bootstrap server (launchd_sim) rather than relying on the host's launchd. In Xcode 6.0 and 6.1, this error message is only displayed in the event that launchd_sim crashes upon launch before the simulator can checkin with it. The only known cause of this issue is from the installation of 3rd party software which alters the behavior of OS X in unsupported ways by setting DYL

As a few on my team are eager to upate, I'm limiting how many devices until I get some good feedback...we've been burned on that before. Please post your feedback on this build.

Hi all,We had a version rejected from the App Store. Problem fixed, and we created a new version. Old version was 2.0.1, new version is 2.1. So, ITC has the 2.0.1 rejected version under Versions. No problem. I upload the new version from Xcode, it shows up in the ITC Pre-release tab, I change the app description and the manual version number, but under Build, it shows 2.0.1, not 2.1. There's no way to change it to 2.1. From what I read, there's supposed to be a + next to builds to allow me to select the build to be tested, but it's not there. I put a note in the developer's note section explaining the problem, but I'm a bit nervous that we're going to wait a week only to be told that there was a problem when I did everything (seemingly) correctly. Anyone else know what to do about this?

I am wondering if there's any available documentation outlining the different approaches to building for OS 1 vs. OS 2, or if it's just the same and the WatchKit Extension code just runs on the watch...

Hi Everyone,SlideOver and picture-in-picture are working in this beta build, but I can't figure out how I can use Split View... is it missing in this version or how can I do this?

The Smart Mailboxes that I'd created under Yosemite disappeared, and Smart Mailboxes don't seem to be working anyway. All my Rules were reset - the Rule is still there, and the Conditions are unchanged, but the rule is marked as inactive, and the target mailbox is wrong. (The latter is an old bug, where the target folder is silently changed to the folder mentioned in the last rule that you edited. It's been around intermittently since 10.7.) The number of messages in an IMAP folder isn't displayed until you select a message in the folder. (In Yosemite it was calculated and displayed immediately.)
