App crash Exception Type: EXC_CRASH (SIGKILL) Termination Reason: Namespace SPRINGBOARD

Since you've got error code 0x8badf00d:

The exception code 0x8badf00d indicates that an application has been terminated by iOS because a watchdog timeout occurred. The application took too long to launch, terminate, or respond to system events. One common cause of this is doing synchronous networking on the main thread. Whatever operation is on Thread 0: needs to be moved to a background thread, or processed differently, so that it does not block the main thread.

More info here.

If your application is terminated immediately, it will be iOS12 (or Beta) problem.

In my case, I am using AD-HOC (distribution provision profile) to test on several users. When users upgrade to iOS12, the application terminates immediately when users launch the application.Also, when I upgrade to iOS12 and launch the application, the application terminates immediately.

In my case the following LOG:

Exception Type:  EXC_CRASH (SIGKILL)Exception Codes: 0x0000000000000000, 0x0000000000000000Exception Note:  EXC_CORPSE_NOTIFYTermination Reason: Namespace SPRINGBOARD, Code 0x8badf00dTermination Description: SPRINGBOARD, process-launch watchdog transgression: com.keyholetv.jp.i-keyholetv2 exhausted real (wall clock) time allowance of 20.00 seconds |  | ProcessVisibility: Unknown | ProcessState: Running | WatchdogEvent: process-launch | WatchdogVisibility: Foreground | WatchdogCPUStatistics: ( | "Elapsed total CPU time (seconds): 2.910 (user 2.910, system 0.000), 7% CPU", | "Elapsed application CPU time (seconds): 0.000, 0% CPU" | )Triggered by Thread:  0

It looks like that iOS12 changes to handle a distribution provision profile. I am not sure that this is BUG on iOS12 or not.
