When I run tests on my project in XCode, it builds, and then says Testing... which never ends.
When I use the stop button, the process stops with this text in the console:
*** If you believe this error represents a bug, please attach the log file at /Users/MY.NAME/Library/Developer/Xcode/DerivedData/APPNAME-gcsubmsjksdbljcswbefkgugjray/Logs/Test/C53D8988-3564-4C2B-A535-075D26D1E4A7/Session-APPNAMETests-2016-07-13_140704-t3DFd5.log
However, I am unable to run the tests again, and have to relaunch xcode to run them.
Is this an issue on XCode that may be known to the Apple developers?
EDIT
So, I figured, the simulator is not launching in time, and that fails the xcode to run the tests. It might be an installation bug with the simulator.
As I anticipated in my edit to the question the first time, XCode installation did not install the simulator correctly.
I trashed the old installed version and reinstalled XCode. And now everything works fine.
Thanks for all the help.
I found that the tests never ran if I was running anything other than iOS10 on the simulator, so use iOS 10. I guess backwards compatibility doesn't really matter.

Today my Mac showed error message above for my own compiled app. This app worked for years. I slightly changed something, but what's the reason for this? How can I avoid it? There is no danger!
I'm using Xcode 10.15 and OSX 10.15.5.
It runs under XCode, but not standalone.
I found the reason/solution.
XCode may had a problem. I copied all files to another folder and restarted XCode with that new location. After compilation everything worked fine (as before).
Seems to be an internal problem of caches of XCode.
Use sign to run locall could fix this issue for me.
Yesterday i updated to the latest version of Xcode, since the update i experience a very strange glitch:
When i try to run the app on a device the Xcode start with the process and say "finish run the app on iPhone" and then the Xcode crashes.
what could cause this problem?
before the update everything worked perfect.
I was seeing this same issue and even trying to view the device from Window -> Devices would cause Xcode to crash. I updated the device to the latest version of iOS (8.0.2) and that seems to have fixed the problem (for this afternoon at least).
i recently received my Macbook and wanted to start developing iOS apps with it.
I Created a default Master-Detail App using the Templates in Xamarin.Studio and everything worked.
Now today i wanted to actually do something in the app, but didn't change a single line of code, still the app doesn't show up anymore in the simulator as long as i want it to use the 6.1 sdk for ios. if i use any other (6.0 etc) it works fine.
I already tried clearing my Cache in /Users/MYNAME/Library/Xamarin/ but this didn't change anything.
What would you suggest me to do now? can i simply reinstall the 6.1 sdk?if so, how would i do this?
Thanks for your help
I had a similar problem where the environment hang when I was trying to debug in the simulator (just showing the spinning ball). I found out that it only occured if I had my phone connected to the computer. Perhaps not valid in your case, but it might be a lead in your problem solving.
I'm using the latest version of everything. :)
From within Xamarin Studio (or MonoDevelop):
Project -> Your.Application.Name Options
Build -> iOS Build (iPhone Build in MonoDevelop)
SDK version: -> 6.1 (it's probably still on 6.0)
This fixed it for me. Also, it wouldn't hurt to make sure the target build in info.plist is set to 6.1.
Delete this folder:
/Users/[username]/Library/Application Support/iPhone Simulator/6.1
And if your Library folder is hidden:
sudo chflags nohidden ~/Library/
I have experienced this problem several times again and my previous answer doesn't solve it. Ya know what does? Rebooting the computer. Works every time. shrug
You need to fill the Application name, Identifier, Version # in the project setting.
I had the same problem and got it solved that way.
Hi I just upgraded to Mountain Lion. I created an empty Single View Application and run it. The first time it runs fine but the next runs will give me the "There was an internal API error" pop-up warning TWICE. It's the same with my other projects. They run okay once but gets this error the next runs. There was no warning or any specific warning message of any kind.
Any idea how to solve this?
Would really appreciate your help.
I have it working on iOS6 Beta 4!! This is what I did but other variations may also work:-
Install XCode 4.5 Developer Preview 4
Delete your app from the device
Run your app from Dev Preview 4
Delete your app again (not sure if you have to do this)
Return to XCode 4.4.1
Run your app, stop running, run again!!!
Of course you could continue developing in 4.5, but I prefer to wait.
Installing 4.5 Beta 4 installs updated device support. Once this is done once (possibly on any device) it should work fine. If you use the same device on a different machine you will have to again run it once from 4.5 Beta 4 before using your preferred version of Xcode (You do not need to delete the app from your device this time).
Edit: I am pretty sure that if you make a change to your core data you will need to run from 4.5 for the first time also.
Don't know if this helps, but I've deleted all files in ${HOME}/Library/Developer/Xcode/iOS DeviceSupport and it worked as a charm (Xcode 4.4.1, OSX 10.7)
I had this problem when I upgraded my device to Preview4 but had my MBP still running Xcode Preview3. Updating to Xcode Preview4 made the problem go away for me, no restarts necessary.
Deleting the app manually from the device/simulator will allow you to build and run successfully. A long term solution is to not use a Beta Xcode :)
Sounds crazy but you can also not use the Beta version of XCode 4.
However, you must keep it in your left hand to authorize your iPhone to compile with the non Beta version (don't ask me why, it works).
If you run your app with XCode 4.5 preview & IOS6 Beta 4, the second time you run your app on the device, you'll get the internal API error.
In theory, you cannot use XCode 4.4 to compile on your iOS6 Beta 4 iPhone.
But...
It seems that, if you launch XCode 4.5 Preview, connect your iPhone (so it is recognized), run the application on it (even if you get the error), quit XCode 4.5, launch XCode 4.4 and .. tadaaaa... your iPhone is now recognized as an authorized device to compile on...
And of course, XCode 4.4 doesn't generate the api error...
I have Xcode 5.0.2 and iPhone with iOS 7.0.6.
Every time when I launched my project on iPhone, I saw "There was an internal API error". And it was launched on simulator without any problems.
I did all the stuff that usually helps (like remove an app, clean, restart Xcode, restart a mac, etc.).
This problem went away only after I restored the iPhone. Sad but true.
I don't know so far, why it appeared.
I am attempting to launch the iPhone simulator from Xcode, but I keep getting the following error:
Error from Debugger: Failed to launch simulator: Operation failed with underlying error: 4294967253.
I've found a number of posts where Xcode failed to launch the simulator, but none of them match the specific error code I'm receiving.
Glad you got things solved senfo. I've found that doing a full rebuild can work as well as checking your system console log for erroneous error message/warnings. Xcode unfortunately seems to be rather poor at conveying errors when deployments fail to the simulator.
Whenever I've had issues like this, Force Quitting the simulator from the dock (Alt-Right click), followed by Xcode seemed to do the trick. After doing that I could reload my project and it would run fine.
Failing that, I hear it might help to reboot your mac (though I've never needed to go that far).
I'm not sure why I didn't try this earlier, but installing the latest version of Xcode fixed the problem.
