I sometimes start to get the following error
2017-04-02 18:55:22.645937+0200 Stamps[730:111791] Connection peer
refused channel request for
"dtxproxy:XCTestDriverInterface:XCTestManager_IDEInterface"; channel
canceled Failed to run tests: The operation
couldn’t be completed. (DTXProxyChannel error 1.)
Last time, when this happened, I just did some random actions with clean my project, remove derived data etc., and it was fixed. Now, it happens again - just after a start of the app, it closes and log contains this error.
What does it mean and is there any workaround here?
I use XCode 8.3, Swift 3.1, test on device 6s with 10.3 installed.
Surprisingly, to fix this, I just replugged my iPhone to another port

I have created some Bots to build, analyze and run unit tests, but I have not been able to make it work in a simulator. All integrations always finish with 12 errors, one for every simulated device.
Assertion: Test target MyAppTests encountered an error (The operation couldn’t be completed. (OSStatus error -1712.) If you believe this error represents a bug, please attach the log file at /Library/Developer/XcodeServer/Integrations/Integration-7d62a04eb43957f1d3098c8ffb64cc13/Session-2016-06-22_20:00:39-svEh7I.log)
This same error repeats itself 12 times. I believe it has something to do with the simulators because the tests only pass on the real devices.
Is there some trick that needs to be done for the simulators to work? The bot configuration for devices is to test with All iOS Devices and Simulatos.
Thanks in advance.
Worklight 6.2 building a hybrid application targeting iPad - we get the symptoms described below in the xCode Simulator irrespective of exactly which target device we select.
The application currently attempts a call to
WL.Client.login()
from within wlCommoninit()
Our target server is a full WL Server running on a Liberty instance on a remote machine, we use HTTPS and a specified IP Address
https://w.x.y.z:443/worklight
We have adjusted the Deploy Target and rebuilt the app before running XCode.
The WL.Client.login() error callback fires and we see log messages indicating that we are attempting to hit the correct URL. We also see this error message
NSURLErrorDomain error -1012
We do have a complex network setup, with a firewall between the iOS simulator and the server and yet if we run up Safari on the simulated device we can correctly access the URL.
Questions:
Does that NSURLErrorDomain reflect the cause of the failure? Or is it just part of the error processing?
Any suggestions for further diagnosis?
Further investigation indicated that we did have the wrong URL configured. It seems that
NSURLErrorDomain error -1012
is not in itself an indicator of the problem. Rather, the error follows from the failure to reach the specified host. Conclusion: study the logs prior top that NSURLErrorDomain message.
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.
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.
