Xcode无法在模拟器上运行应用

Question

Yesterday I uninstalled my App Store install of XCode and installed it manually from the Apple developer site.

I had 9.4.1 and downloaded 9.3

Ever since I've not been able to run any apps on the simulator.

I see the following error in xcode:

I see this error in the Xcode logs:

iOSSimulator: 56E6A4AD-4D6F-4CB4-A666-E1DE0D49B101: Failed to launch app with identifier: com.mikevelu.Test and options: {

"activate_suspended" = 0;

arguments =     (

);

environment =     {

    "DYLD_FRAMEWORK_PATH" = "/Users/mikemurray/Library/Developer/Xcode/DerivedData/Test-fqvnwaelkrhrooepamzxmakiidkf/Build/Products/Debug-iphonesimulator";

    "DYLD_INSERT_LIBRARIES" = "/Applications/Xcode9.4.1.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/libBacktraceRecording.dylib:/Applications/Xcode9.4.1.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/libMainThreadChecker.dylib:/Applications/Xcode9.4.1.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/Develope<…>

and I see this error in the simulator logs:

(UIKitApplication:com.mikevelu.Test[0xf61e][2808][2983]): Service could not initialize: 99Z999: xpcproxy_sim + 9282 [1524][AF02A7E2-099C-3F21-AB91-5AA7DB3FFA58]: 0x5

I've tried the usual culprits, removing derived data/cleaning build folder/restarting simulator/restarting xcode/restarting macbook.

I've also tried completely uninstalling xcode and reinstalling (uninstalled 9.3 and tried installing 9.4.1), doesn't seem to make any difference.

Seen a few similar questions posted and one of the most common fixes seems to be removing any checked blank environment variables in the scheme, I can't find any to remove. I've tried running both in debug and release, I've tried disabling Debug executable and selecting the executable on launch. Also tried deleting the scheme and creating a new one.

Also set verbose logging on the simulator and I didn't get any more illuminating information.

If if install the app manually using simctl and launch it using simctl it will launch without complaints (that's what prompted me to try disabling debug executable).

I see this issue regardless of which project/workspace I have open in Xcode, the example I'm using currently is just a blank project I created to try and get to the bottom of the issue.

I'm edging closer and closer to a complete restore being the most logical next step, but I'd like to avoid that if possible.

*EDIT - Discovered the issue was with anti virus not liking it when xcode wasn't named Xcode.app. Sigh.

So, it looks like renaming the Xcode.app file now leads to some pretty ropey behaviour.

Up till now when managing multiple installs of xcode I'd just rename the files to something like Xcode.9.4.1.app, not sure when/if that's changed but the only way I can fix the simulator issue is to keep the Xcode.app filename.
