There are no options in Simulator 11.4 (921.9) to hide the the title bar. Unfortunately, since the title bar is close to the top of the bezel and casts a shadow of it's own, you can't just crop it off or you'll have an odd shadow at the top of the image. The workaround I use is to turn off shadows for the screencapture utility, then I can crop out the title bar cleanly (I cut off the top 46 points). If you want shadows on your final image, you can add them back with image editing software. It's mult step, but it gets you there.Turn screencapture shadows off (using terminal)defaults write com.apple.screencapture disable-shadow -bool TRUE; killall SystemUIServerTurn screencapture shadows on (using terminal)defaults write com.apple.screencapture disable-shadow -bool FALSE; killall SystemUIServer

I had a similar problem where a new build would show in the Apple Developer Portal as "Ready to Test" but would not show up for Internal Testers in the TestFlight app. For me the solution was to "expire" all previous builds. Once I did that the new build immediately showed up in TestFlight. Normally I don't do this and I typically have many builds "available" so I was wondering why I had to expire all builds this time. What was different... Before this build my Apple Distribution Certificate had expired so I did have to make a new one before the upload process would complete. So my suspicion is that TestFlight will not show builds for the same bundleID signed with different certificates. That would explain why expiring old builds solved the problem.
