Using El Capitan Beta 6 and Xcode Beta 4.

Simulator is now trigger constant Springboard crashes with EXC_BAD_ACCESS every few seconds. Cannot run unit tests or app.

Simulator screen is black and reset/shutdown does nothing.

Haved tried:

* Clearing all simulator settings from ~/Library/Developer/CoreSimulator.

* Clearing DerivedData.

* Reinstalling XCode.

* Clearing cached data.

Does anyone have any ideas what else I can try or is this a dead duck until a XCode beta 5 arrives?

Hi drekka,

This has been a very widespread problem. The good news is that it has resulted in a fix:

From Terminal (copy-paste the following in bold):

cd /Applications/Xcode-beta.app (or wherever your Xcode 7 beta 4 is located)
cd Contents/Developer/Platforms/iPhoneSimulator.platform
cd Developer/SDKs/iPhoneSimulator.sdk/usr/lib
sudo mv dyld_sim dyld_sim.orig
cd /Applications/Xcode-beta.app (or wherever your Xcode 7 beta 4 is located)
cd Contents/Developer/Platforms/WatchSimulator.platform
cd Developer/SDKs/WatchSimulator.sdk/usr/lib
sudo mv dyld_sim dyld_sim.orig

There's also a one-liner that should do the same thing as those 8 steps, but I haven't tried it so can't attest to it's efficacy:

sudo find $(xcode-select -p) -name '*dyld_sim*' -exec mv -v {} {}.orig \;

Sorry that didn't work for me. Cant get the simulator to work on xcode 6 or 7 beta. Springboard constantly crashes.

After I wrote the original post I found this large thread https://forums.developer.apple.com/thread/13170?start=0&tstart=0

Reading through it I came across the same solution as suggested by Max108. I've now run his one line solution on two machines and it has fixed both.

You might find some other things in there that will get you going again.

Best of luck.

This is happening after upgrading to Xcode beta 5 also. And the Downloads pane under preferences now shows no simulators at all.

Deleting the simulators from /Library/Developer/CoreSimulator solved the crashing problem and I can run in an iOS 9 simulator. But Xcode still refuses to download any other simulators so only iOS 9 simulators can be created.
