进入主屏幕时，Xcode与模拟器或设备断开连接

Question

I'm trying to debug an handoff issue in Xcode, but the debugger disconnects every time I go to the device homescreen. This happens on both the simulator and an actual device.

I have other apps where it works correctly; that is, it continues to debug when I go to the homescreen.

Any ideas what could be causing this? I've rebooted Xcode and my Mac with no luck.

When running on the device, the log has a message that looks like:

Jun 28 16:36:31 Mikes-iPhone com.apple.debugserver-@(#)PROGRAM:debugserver  PROJECT:debugserver-340.3.124

I'd appreciate any ideas or suggestions....

Well this was dumb. At some point I had changed the "Application does not run in background" plist flag to YES. Simply changing to NO fixed the problem. Duh.
