My iPhone application suddenly stopped launching in dev mode.
When I launch in simulator it pops up a dialog: SpringBoard failed to launch application with error: 5
There are tons of references on the web about error 3 and 7, but not the 5. I tried to follow the suggestions for the 3 and the 7, clean up the app, remove it from the simulator, restart the xcode etc... -- does not help. Can anybody shed some light about this mysterious error 5 and how to overcome it?
After a while the issue came back, so digging into it, revealed, that I must have accidentally turned on location simulation option in the Run configuration as well as Background fetch (launch due to background fetch event). I was playing with the background fetch and the location events, but decided not to use it after all. Turning those off in the run scheme brought my app back to live.
I got the same problem 2 hours ago then I closed the iOS simulator and Xcode then run it again it worked perfectly try it maybe it will work.
So, here is the answer. It's got something to do with the background location service. Apparently it was disabled for my application. Once I removed it from the Info.plist -- things started clicking again. Put it back -- the same exact issue. One would hope, the messages I got would be a bit more user friendly. Anyways, thanks for helping me.
Adding to dmitryame's answer, solving this issue for me was only accomplished by unchecking "Launch due to a background fetch event"only by Under Edit Scheme / Run Configuration.
Below is an image of the culprit causing the error message in my case:
Quit Simulator and clean Xcode. The fresh build will not show this Alert again. The possible reason for this might be switching between 64-bit simulator and 32-bit simulator.

I just updated to Xcode 7 and ran an app on a live device. Now for some reason, I get an error when I try to run an app in a simulator.
Stop “(null)”?
An instance of “(null)” is already running. Choose “Stop” to terminate and launch a new instance.
When I press the stop button it grays out, as in the screen shot, but nothing happens. I have tried resetting the content and settings on the simulator, but that didn't help.
Getting this as well with Xcode 7.
I've been following these simple steps to avoid seeing the error:
Build your app.
Run your app.
Annoying, and not a solution, but I think this is a bug within Xcode 7.
Completely quitting Xcode 7 and reloading resolved the simulator is already running it for me.
I got this error too, and building and then running the app (cmd+b ; cmd+r) solved the problem.
TL;DR: This is a recurring error in XCode 7 with no known solution. To get rid of it, disconnect your device, then reconnect and carry about your day. If running the simulator, kill it, then restart it. Hopefully Apple addresses this soon.
When you get like this stop (CMD+.)the stop the project.
->Quit Xcode
->Clean the project (CMD+Shift+K)
->Build the project(CMD+B)
->Run the project(CMD+R)
If you are running on an actual device, I found that by disconnecting the device (iphone) from the computer/laptop and reconnecting eliminates this error/issue.
However, I still see in xcode the following message:
running <app name> on <phone name>
But at least I do not need to quit xcode.
I did not have this when running on a simulator (always testing on a real device...)
I suggest building your app and then cleaning it. For me, this ensured that later on I could just run the application.
No app can run in my simulator, although building is good.
Error messsage is below:
Unable to run app in Simulator
An error was encountered while running (Domain = NSPOSIXErrorDomain, Code = 3)
In my case, I tried to run the app on a iPhone 6 simulator when I got this error. Quitted the simulator only and re-ran the app on iPhone 5s (8.1) - it worked fine.
After a while I changed the target back to iPhone 6 (without quitting it), and ran the app against it - no error shown.
As mentioned in the Xcode 6.1 Release Notes and in my sticky post in the Apple Developer Forums for the iOS Simulator, this is a known bug in iOS.
Upon installation of an app, SpringBoard will SIGKILL that app's
process in order to force a relaunch of the app with the new
executable. The problem is that there is a race condition whereby
SpringBoard may accidentally SIGKILL a new process that we just
launched rather than the old process. Which of the various error
messages you get depends on exactly when in the launch process the
SIGKILL was delivered. Normally, this shouldn't happen, so the advise
is to just try again (sorry =/). If you find that this happes to you
all the time or more frequently than you can tollerate, we are
incredibly sorry. We are aware that systems with slower disk I/O will
see this happen more frequently than faster systems, so if you are
using an NFS home directory, you may want to create a local directory
for your simulator data and setup a simlink to it from
~/Library/Developer/CoreSimulator
By Quitting the Simulator and Run the application worked for me.
For me , just Reset Content and setting in your simulator
Restart Mac can solve the problem for me.
This error is less severe than "Domain = DTiPhoneSimulatorErrorDomain, Code = 2" error that I had when I switched to Xcode 6.
For this one, I just reset and cleared contents on my Simulator...quit. Rebuilt and ran my app...and it works.
Every time this has happened to me (as of this writing, still happening on Xcode 6.1) I do not need to restart my mac to fix it. Instead I only had to restart the simulator. I exit the simulator by right-clicking on its icon in the tray and selecting the option to Quit. The I re-run my app and the simulator starts from scratch and runs my app with no error. Much quicker than re-starting the mac.
Well, I had the same error popping up, but since I force quitted the simulator then ran the project again I got it fixed and running fine. Hope that helps you :)
If this error occurs with ionic framework, make sure you have an app id given in your config.xml
This is a generic error which says that it is unable to launch the app. The real error is in the log file. Go to the Simulator menu, Debug / Open System Log. Then press Reveal button to open the folder with actual Simulator logs. In my case it was CoreSimulator.log.
Here you will find the real error. My error was Could not register service com.apple.gputools.agent.producer.sim .
After a lot to struggle and trying all suggestions for half a day, I just went to simulator menu and chose File / GPU Selection / Use External GPU when available. That's it.
please download new xcode_6 beta 4. your project will work in simulator. As i have tested as well.
Sometimes the beta version of XCode is wrongly configured to use the command line tools from the previous xcode version.

I'm developing for iPad (iOS 7), using Xcode 5.0.2.
Yesterday morning I was playing around with the app (my first app) and every time I ran it, it was displayed in the emulator perfectly. But after some 5/6 runs Xcode just stopped launching my app in the simulator. I started to receive this message:
MagazineManager exited unexpectedly - lost connection
Image:
I've been researching since yesterday morning for a solution with no luck. I even uninstalled and reinstalled Xcode, cleared the cache, delete folders... all that drama thinking it could be some sort of cache problem.
Then, going online I've tried lots of "solutions", none worked.
I've tried all listed here: Xcode suddenly stopped running project on hardware: "Could not launch xxx.app: .. No such file.."
and here:https://discussions.apple.com/message/23431537#23431537
and in more places.
After all my "try this, try that" I'm stuck with the same problem. I can only see a black screen at the simulator (image below) and that message at Xcode!
In my extensive research I've read that people are still able to debug using their iPad's. The problem is that I got the new iPad air, that's only getting here dec, 20th!! So I don't have a place to test my app[s].
Thanks!
UPDATE
Just got this message in the debugger console:
013-12-09 20:23:25.902 sim[607:303] /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/usr/bin/sim: Did not find an executable file at the path: '/Users//Library/Developer/Xcode/DerivedData/MagMan-bvhhiijesvrvuteunbmpsxcqgsst/Build/Products/Debug-iphonesimulator/MagMan.app'
My problem was the debugger. Actually, it still is.
The way I solved, and have been doing for every new project, was to disable the debugger and then run the project. That way I'm able to use the app on the simulator but without the debugging functionality.
I don't know what the problem is, what is causing this debugger issue in my case, but for now that's the best I could come up with. Thanks to the friends that replied to my question and helped my research I was able to test it and disable it.
This is how I disabled the debugger:
Project > Edit scheme
Set Debugger to None
If anyone knows a solution for this, feel free to answer this question and I'll make sure to update the selected answer accordingly.
Again, thanks for all your time and patience, specially #Popeye and #HotLicks that spent a lot of their time trying to help me.
Sometimes the simulator can be a bit flaky and just needs resetting. In the navigation bar at the top of the screen when the simulator is visible try:
iOS Simulator --> Reset Content and Settings...
This should reset all the settings and remove the content so all data, images, apps etc will be removed, its like it has never run before.
UPDATE
The answer on XCode5 can't install app on iOS simulator indicates the following
I found a "Fix" for this. After trying everything and getting the same error on "My App", I opened and tried to run "My App 2". "My App 2" ran fine, so I went back to "My App", tried again and this time everything worked fine. Crazy
If that doesn't work leave a comment and I will have another look.
Delete the app and restart your iPad it will work
I have been at this for hours and am about to start flipping tables. This problem cropped up out of nowhere after working on this app successfully for about a month. No changes to build settings or build schemes or anything that I can think of.
If I build and run the app on an iPhone 4 I have no problems at all. If I build and run the app on an iPhone5S it will:
On the first attempt: Build successfully, appear to install the app on the device and launch it, but then fail with "error: failed to launch '.../MyApp.app' -- NotFound".
On the second attempt: Build, run, have a happy little debug session and everything is perfectly fine and dandy.
On the third attempt: Build successfully, begin to launch the app, and then will fail with "error: failed to launch '.../MyApp.app' -- Failed to get task for process -1". The phone will then become unresponsive, and the only way to bring it back is a hard reset.
Once or twice throughout the past few weeks I've had this problem happen, but after resetting everything was fine. Turning on or off building for arm64 doesn't seem to make a difference, and I can't think of anything else that would be different between the two devices.
Even a hint would be appreciated.
UPDATE: I changed the build scheme to "Wait for app to be launched manually", and by launching it myself after it's been built it seems to avoid the crashing. Obviously this doesn't fix whatever the underlying problem is, but at least I can function now.
Looks like this is a known bug, and it's resolved in Xcode 5.0.2.
I'm experiencing this very same issue but the workaround I've found is to disconnect and reconnect the phone before running the app. Using this workaround, I haven't experienced the error as frequently as otherwise, but it's still a rather tedious process...
This problem is known back to first Xcode 5 Previews. It helps to disconnect and connect the phone again. MY worst experience was Preview 4 with iPad. It till happens occasionally, but very rare compared to before.

iPhone Simulator: SpringBoard failed to launch application with error: 7
(22 answers)
Closed 9 years ago.
Launching apps from Xcode 5 to the iOS simulator (multiple OS versions) fails with SpringBoard failed to launch application with error: -3. I can get around the problem by 'turning it off and back on again' (quitting the simulator and relaunching, uninstalling and redeploying the app, etc.), but it seems to come back again later and in other projects.
Can someone help me understand what the real problem here is and if there is a permanent fix?
I don't know why, but on my end deleting the app from simulator solved this.
Quitting simulator seems to help.
Run Activity Monitor and force Kill the simulator process. Then Run you app again and simulator will launch automatically and problem goes away.
I think this may be because you have installed (run) it on 64bit iOS7 simulator and now you are trying to use same install/files on 32bit simulation.
1) Press stop button from Xcode
2) Exit Simulator
3) Press run button again from Xcode
This is the quickest workaround that I have tried, did not have to delete the app or do anything like that.
Restart simulator, if it wont solve your problem and then delete all content. It worked for me.
I noticed I started getting this error when manually editing files that are in the Emulator's disk space.
With "the Emulator's disk space" I mean a path similar to this one:
~/Library/Application Support/iPhone Simulator/7.0/Applications//.app/
Having the build process re-run solved my problems too so I feel like it has something to do with file permissions or some sort of checksum failure.
