I just created my new iOS project as a single view app and tried running it with no codes added, but there appears just a blank black window in the iOS simulator, and it generates the below error:
"The operation couldn't be completed. (Mach error -308 -(ipc/mig)server died)"
Have a look at this question:
Swift Playground and Simulator Error (ipc/mig) server died, Unable to boot the iOS Simulator
Hopefully that will help you too.

I'm using XCode11 and ionic4. cordova version ios#5.0.0
project builds successfully using ionic cordova build ios
also successfull build in xcode
but when running on simulator, it end up showing white screen and nothing happens next. here is the console output showing the issues:
Log1
Log2
stuck on this for 4 days. checked so many suggestions on ionic blogs and nothing worked so far. I regret using ionic because its very buggy/unstable... please help
ISSUES:
-Failed to load webpage with error: the operation couldnt be completed(NSURLErrorDomain error -999)
-NSURL Connection finished with error -code -1100
-ERROR: HTTP Request(OSRequestRegisterUser) must contain an app_id parameter
-ERROR: Encountered error during push registration with OneSignal
in addition to the above errors, the iOS simulator hangs on "White Screen", the application does not load and nothing happens next.
Try this:
On your xcode, navigate to your plugin folder, locate a file named OneSignalPush.m
Inside, locate the initOneSignalObject,
add this: appId = "your-app-id-here";
right after this code:
[OneSignal setValue:#"Cordova" forKey:#"mSDKType"];
That did the trick for me.
Issue
Most times, when I try to debug my custom keyboard extension, I receive the following error and then the keyboard disappears (presumably crashes, so the system removes it from screen and replaces it with the standard keyboard)
plugin com.db.Trype.TrypeKeyboard interrupted
(Note: Trype is the name of my keyboard.)
Process
I am debugging the keyboard the following way:
I have the keyboard extension as a target.
I've modified the TrypeKeyboard scheme to run my app executable on launch.
The keyboard has been added in the Simulator's Settings App.
I've tried different version of Xcode-Beta and tried restarting the simulator, computer, etc., all to a varying degree of temporary success.
Anyone else run into this error and have a suggestion?
Update:
Here is an accompanying error message. Maybe there is some way to print out more of the UserInfo?
viewServiceDidTerminateWithError:: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3
"The operation couldn’t be completed. (_UIViewServiceInterfaceErrorDomain error 3.)"
UserInfo=0x7fc99c900a50 {Message=Service Connection Interrupted}
After messing around with it some more, I'm beginning to conclude this is an iOS 8/Xcode bug with the way that extensions are debugged.
Xcode sometimes seems to build project and install multiple versions of the extension keyboard into the iOS simulator. It also occasionally kills the extension and reloads it. Very strange behavior. Just sitting and staring at the debugging sidebar shows it get killed (disappear) and then relaunch.
The first is a successful launch.
The second is an unsuccessful launch where the extension appears to hang and wait to attach.
recently I was playing around with the custom keyboard extension in iOS 8 Beta with Swift (Xcode beta 6), but I keep getting this error when I run it on a simulator, it seems to be quite random and I've no idea what causes it:
plugin com.name.app.extensionName interrupted
Hub connection error Error Domain=NSCocoaErrorDomain Code=4097 "The operation couldn’t be completed. (Cocoa error 4097.)" (connection to service named com.name.app.extensionName) UserInfo=0x7b087720 {NSDebugDescription=connection to service named com.name.app.extensionName}
I have no idea what to do. I can't test the app on a real device at the moment, therefore I'm stuck here. It happens on all types of simulators, I already reset them and restarted Xcode and my computer.
I hope you can give me any advice or maybe even know a fix!
I had this problem in Today Extension written in Objective-C. After updating to XCode 6.0.1 and building my project it started saying about missing ARM64 Architecture. When added arm64 it started working well. Try to play with it
I tried a variety of things to resolve this and ultimately what fixed it was "cleaning" my application (on the "Product" menu). I don't know what that really does, but I "cleaned" it, then restarted the simulator and suddenly everything is working again.
I have just downloaded XCode 6 and adjusted my application to run under it.
It seems to work just fine, however I use SFHFKeychainUtils, and when I run the application in the simulator I get the error:
error getting UUID: The operation couldn’t be completed. (SFHFKeychainUtilsErrorDomain error -34018.)
Looking at the code, I'm not quite sure why I would get that error. I also do not get that error running my application on an iOS7 device running from XCode6, just the simulator, so I think it's an iOS 8 error.
Any thoughts on resolving this?
Error code 34018. It happens when client has neither application-identifier nor keychain-access-groups entitlements.
iOS 8 is BETA version and doesn’t support Keychain Access developer APIs on the simulator at the moment.
iOS 8 beta Release Notes
When I try to do anything in Playground, this pops up before I even finish typing a word.
Error running playground.
Failed to launch iOS stub for playground: The operation couldn’t be completed. (Mach error -308 - (ipc/mig) server died).
and when I just try to run IOS Simulator I get the following error
Unable to boot the iOS Simulator.
oh and this error just popped up
An error was encountered while running (Domain = DTiPhoneSimulatorErrorDomain, Code = 2)
I tried rebooting, I closed out and opened again, I deselected file and reselected. Just keeps happening. Anyone have a solution?
Your firewall is blocking the debugger, you need to allow it to connect:
TCP out 127.0.0.1:63748
Or allow the debugserver process open access (whichever you, or your firewall, prefer(s)).
Upon enabling it, and restarting Xcode everything should work like a charm.
Note/Update:
If you're having trouble finding, or allowing, the debugserver simply try, temporarily, disabling your firewall and restart xcode. Does the playground work? Oh, and don't forget to make sure you've got the assistant view open and the output box showing.
Currently the Xcode 6 beta needs to reside in \Applications for the playground and simulator to work. After you move it there you need to reboot.
This error popped up for me when I closed the simulator before Xcode finished attaching my application to it. Opening the simulator and running the app again solved this problem.
