Simulator keeps crashing in Xcode 4.4 - iphone

When ever I run my app in Xcode 4.4 the simulator fails to open, "iOS Simulator quit unexpectedly." It runs on perfectly on the device though.


I solved by installing xcode 4.5 and ios sdk 6. Now all work fine.


You may have had a bad build on the Simulator, which is now messing things up.
Clean your code (Product > Clean in XCode)
Reset your simulator settings (iOS Simulator menu > Reset Content and Settings)
That should do it.


I Had the same problem i just did following steps and it works fine
1) Reset your iPhone simulator
2) Clean Build your code
3) Restart your computer
Its works for me.


Reboot the simulator ..... sometimes some apps remain in the memory.... Otherwise reinstall it ... some data could be corrupt... :)


I had the same issue on Lion.
After upgrade to Mountain Lion I haven't such issue.

When compiling, the simulator does not start in Xcode on Apple MacBook Pro M1

When I create a new project everything works fine
But when I try to run a project from my repository which was create on another MacBook , the build is successful, but the simulator simply does not react to it at all

might be a dumb answer, but did you select iPhone or iPad in the simulator setting? sometimes simulator is set to Any iOS Devices

Error when opening simulator with iOS 8 beta

I have recently installed Xcode 6 beta in OS X Mavericks, with which comes the iOS simulator for iOS 8.
using this new Xcode I have create one new project and run it on simulator with iOS 8, but when opening the simulator, it always get the error
Unable to boot the iOS Simulator
So, pls tell me how to solve this error?

Quit both the simulator and Xcode. If that doesn't fix it, reboot your Mac.
Welcome to the world of beta builds!

Be sure you "select" your new Xcode version before launching / downloading updates.
sudo xcode-select -switch /Applications/Xcode6-Beta6.app/Contents/Developer/
If you're already seeing Simulator troubles, try rebooting too.

Make sure that you load X-Code 6 and not 5.
Run your project.
If fails to load, try clicking on the menu at the top on the iOS Simulator button and reset the device. Resetting the device seems to do the trick for me.
Also, make sure you are on the laatst x-code version

IOS simulator failed to install application? in Xcode 5

Currently it shows only black screen. So i'm unable to Reset simulator.
But in iOS 6.1 app is working good.

I got this problem before 15 days.
you first delete all XCode related file which is being installed. and reinstall your XCODE 5.
you can refer following link for uninstalling XCODE

You can refer this similar question
Xcode5 Facing strange issue with testing app iOS Simulator failed to install the application

currently it shows only black screen.SO i'm unable to Reset simulator
By writing this you mean you can not access even iOS simulator > Reset Content and Settings ???????? If you can then try it.

I had tried these, and still had the problem, even after reinstalling Xcode 5. So I ran from Xcode again. Same thing, error -3. I stopped the app from Xcode, but I decided not to reset. Instead I decided to manually start the app in the sim. It took a few seconds, but it ran. Pressed stop. Reran the build from Xcode, and it worked.

iPhone does not stop at breakpoints

I have installed Xcode 4.3.3 on Max OsX Lion and now when I debug my application in the simulator in iOS 5.1.1 then it stops at breakpoints but when I debug on an iPhone device with iOS 5.1.1 then it does not stop on breakpoints.
I have no idea why it is not working properly. I have researched alot but did not get any solution. And my device is jailbroken and I updated its iOS from 3.1 to 5.1.1. please help me if anyone knows.
i have tried these links as a solution but no works in my case:

iPhone Device Debugging

It must be a bug cause I had the exact same Problem even with a non jailbreaked iPhone and it worked after I installed 10.8 on my Macbook Pro. I don't know if that is an option for you but it worked for me.

I found the problem, Somehow the "Show Disassembly when debugging" was enabled in my Xcode which creates that problem. When I disabled it, all my debugger stopped in my source code.
You can find it under Product->Debug Workflow->Show Disassembly when debugging

Error : The service is invalid

I am having some problem in installing my app on the iphone as I am constantly getting the following error message
The service is invalid
Please check your setup and try again
(0XE8000022)
It was running perfectly well till yesterday but since yesterday I am having this problem.

Xcode and the GDB connection is quite temperamental. The device and your Mac can become unsynchronised with each other. My checklist for this sort of thing:
Restart Xcode.
Delete the .app from your iOS device, do a Clean then Rebuild.
Disconnect, reconnect device.
Restart iOS device (90% of the time it fixes things)
If all else fails, restart your Mac (unlikely but it did fix an issue once for me).

I have solved the problem... Only needed to restart the iphone...
Restarting the Xcode wont work in this case. So just restart your iPhone and everything will be fine.
EDIT:
If you have an iPhone 5 running iOS 6.0 and have installed the "iOS Updater" app, you will also have this message.
Finishing the update process to iOS 6.0.1 will resolve the problem.

If you have an iPhone 5 running iOS 6.0 and have installed the "iOS Updater" app, you will also have this message.
Finishing the update process to iOS 6.0.1 will resolve the problem.

This error also happens if the iPhone provisioning profile has expired.

It can be a couple of things, the first and inmediate thing I'd check is to see if your IPhone is currently Downloading or "Preparing Update..." whilst this is running you generally get the "Device is invalid (0xe8000084)" / Error MT1006.
This i found to be the most common thing. so try this first.
And if that fails: Restart your IPhone, and then if that fails restart your Mac/Xcode
and do a clean then Rebuild and deploy..
Hope this helps

This error happens when you try to debug an application in your IPod/IPhone and the device is code-locked or executing another application.
Make sure you can see the menu with all the app icons on the device and try to run again.

If nothing works then check if your device os is compatible with your Xcode version.

I confirm that restarting your device solves the issue.
But if your device is jailbroken with a Semi-tethered jailbreak you will loose it after a reboot.
To prevent this, do a ldrestart(soft reboot).
In order to perform it, download a terminal application from Cydia, then type:
su
Input your password when asked, the default password is "alpine".
Then type
ldrestart

Unplugged the device and connected again with Mac solved my issue. Did not need to clean, build or restart XCode. XCode 10.2.1, iOS 12.3.1 version.

First remove the app from iPhone before building the app from xcode.
Then Clean All Targets from xcode and then try to build your app again.

SnowLeopard w/ XCode 4.2's Instruments will give this message on newer iOSes.

I had luck by disconnecting my iPhone from my mac, and then Analyzing (Shift + Command + B or Product -> Analyze).
After that I plugged my iPhone back in and did a clean (Command + k) and then run. Worked!

Simply restarting the device (as the alert suggests) fixed the problem, at least on iOS 12.
