I am currently running 2 versions of xcode. I recently upgraded from
9.3 to 9.4.1 and also xcode 10 beta 6 on High Sierra v.10.13.6. The
simulators seem to work fine in xcode 10 beta 6 but are completely
missing from 9.4.1 I have downloaded and installed additional
simulators which show up in the simulators window list, however they
are not added to the drop downs in the main project window and the devices list remains empty. I wondered
if its simply that I have messed up something in the installation. I
have tried to remove everything and reinstall and got the same problem.
Any advice would be great. If anyone who is also running two versions could recommend
also optimum set up with installation etc. I can
post more detail as required. I have added screen shots please follow
the links.

I had a similar issue. If I created a new account on the same system that new account did not have the same issues. This lead me to believe it was a user preferences issue.
Some of the advice for fixing this involves deleting all Xcode files and re-installing from scratch. Try the solution below to see if it works for you since it’s much faster and less work.
Quit any running version of Xcode
Delete the folder: ~/Library/Developer/CoreSimulator
You can see from the attached screen shot there is a device_set.plist file. Deleting this file alone doesn’t help so delete the entire directory it’s inside of.
Launch Xcode
Select Preferences and go to the “Components” tab.
Download ANY new simulator
Once downloaded you should see all of your simulators showing up. It seems to be the process of downloading a new simulator rebuilds the list of installed simulators.
Note I tried downloading a new simulator w/out throwing away the above directory to see if this would rebuild the list of simulators but it did not work.
After upgrading to Lion, Xcode 4.1 is no longer building my iOS apps with the latest changes incorporated (i.e code, bundle name, icon changes).
Before the upgrade, when I was using Snow Leopard, no matter what the change, or even if I replaced a file outside of Xcode with Finder or used an external text editor, Xcode would always build a fresh copy with all of the changes incorporated, without having to do any extra steps.
Now, Xcode seems to insist on using a previous version, and the only way I can be sure that it will build with all of the changes incorporated is do a Product > Clean from the main menu and then restart Xcode.
What's going on here? Is there a simple setting that I am missing? I never had to anything except click Run when I was on Snow Leopard, and all changes were always incorporated without a glitch. If I can't fix this I am going to revert to Snow Leopard.
Delete the "Build" folder in your app's folder on your computer and try running the app again. That should fix it.
Lion is known to have this issues with Xcode. I solved this by installing the newest beta available. If you don't have access to the newest beta try uninstalling and reinstalling. To uniinstall:
sudo /Developer/Library/uninstall-devtools --mode=all
Go the folder
/Users/%yourusername%/Library/Developer/Xcode/DerivedData/%yourworkplacename%/Build/Intermediates/
delete the projects that you want them to rebuild.
It works for me to make the modified file take in effect after I run it.
I faced same problem and I solved this.
On creating build and after installation of app if you don't get the changes that you made in it, means '.app' was not updated properly.
To fix this problem:->
First delete '.app' from project in Product folder and then make
archive (Xcode-> Menu Bar-> Product-> Archive, we dont do any thing of
this archive, Now close that organizer window)
Now clean your project and then make build by taping build option.
Now build is updated with your latest work.
I've experienced plenty of issues with taking "old" projects into newer versions of Xcode. If it's not TOO painful, I'd make a new project and just add all your classes and resources to it to make sure it's fresh for Xcode. This isn't trivial in some cases, but it's more likely to fix your issue.
Had a similar effect where every change appeared to be ignored, Xcode said it compiled but the simulator showed a previous version. Even when I did a clean and rebuild.
The problem was in the simulator, I noticed 2 icons of the same project. I uninstalled them both in the emulator and run it again, this time correctly with all my changes.
Guess the problem appeared because of changes in the name of the project bundle, this must have confused the simulator. so deleting the apps in the simulator did the trick.
I am keep getting this error while uploading..I have no idea what this error are and how to resolve them...my build was successful(there are some warnings) my application is tested on iOS 4.1...any help is highly appreciated.
Thanks
It appears that Apple's servers may be having issues this weekend. I got a similar error. You should check iTunesConnect to see if the binary was uploaded, and perhaps send email to ITC support confirming.
I had this issue as well and was able to get around it by using Fink.
Basically, the issue was that Application Loader.app was expecting to find servlet.jar in my classpath & by not finding it, was throwing a Java error. I tried with both the iOS 4.1 version of Xcode & Application Loader.app and the iOS 4.2 versions.
Solution:
Download fink & install.
fire up Terminal.app
fink install jakarta-servletapi
quit Terminal.app & relaunch it (it should automatically update your shell)
cd /Developer/Applications/Utilities/Application Loader.app/Contents/MacOS/ (assuming you have installed the dev tools to the standard location)
./Application\ Loader
smile
This is what worked for me, hope it helps? You can probably achieve the same thing using other tools (such as DarwinPorts?), but I have chosen Fink given that's what I first picked years ago... :)
The local installation of XCode seems to be broken. Uploading the file from an other system does not show any problems.
I try to reinstall XCode and hope that fixes my problem.
I'm trying to install Zxing on my iphone from source (I know I can get it at the app store, but I want to modify some things in it).
The problem I'm having is that the app won't stay installed on the phone. It will run without a problem, but no icon will appear after I quit the app. I thought it had to do with my manually editing the codesign information in the project.pbxproj but after the developers changed the codesign identity they had left in the checked in version, the problem still persists.
I tried deploying an app I had developed from scratch and that worked fine.
I'm new to this, so any help would be much appreciated. You can download the zxing code from here:
svn checkout http://zxing.googlecode.com/svn/trunk/ zxing-read-only
Have you downloaded a copy from the App Store? I had one app (built from Xcode) that wasn't staying around after a sync and I found it was because iTunes was looking at my application syncing preferences and it wasn't selected to sync (as I had the Xcode build version on there, I didn't want to sync that version). However, it presumably removes the built app because I said I didn't want to sync any version of it.
Checking the checkbox to sync the app in iTunes kept the Xcode built version on there without installing the App Store version.
Hope this helps.
I think the problem had to do with my iPhone firmware. It might be a bug from Apple as I got an email from truphone saying that users were experiencing similar problems. I re-installed firmware, and could install it fine, and sync other apps. As soon as I did a restore from a previous backup, it broke again... what a pain. Case closed.
Problem
Unlike people have asked at here and
here, I got this error after a brand new installation of Leopard (hackintosh), this problem really driving me crazy and nowhere else to find an clue, I googled and visited every article related with this, still can't get it solved.
After the first time install iPhone SDK 2.2.1, start a new project(any type, Navigate based, OpenGL ES application), then build and go, I got the following problem:
sometime it's:
Failed to launch simulated application: Unknown error.
and sometimes it's:
Failed to launch simulated application: iPhone Simulator failed to find the process ID of com.yourcompany.[application name]
It seems that apps in the simulator crashed immediately, so Xcode can find the process ID.
Solution
This link says that this even can't be solved. Some others make a detailed step by step:
Uncheck Info.plist
Quit XCode
Delete directory /Lib/Caches/com.apple.DeveloperTools.###
Open Xcode project
Clean All Targets
Rebuild
and I reset the iPhone Simulator. This also didn't solve the problem…
I've even tried uninstall the SDK and reinstall it, still got the same error…
Is this a problem related with hardwares? or the operating system version? I'm using a hackintosh (iDenebv1.4 10.5.6), all other software works good including iTunes && vmware fusion.
Great thanks for any further tips or clues!
FIXED For the issue:
iPhone Simulator failed to find the process ID of com.yourcompany.[your application name]
I was having an issue building and simulating a project I built under OS Version 2.2.1, which I could no longer get to build and run in the simulator for XCode 3.1.4, even though I forced XCode to build for "Simulator - 2.2.1 Debug"
I was able to get past this problem by:
- Close the iPhone Simulator
- Putting XCode into View->Detail
- Opening the "Info.plist" file in the "Resources" folder
- Near the top of the file you should see "Info.plist" with and up/down arrow selector
- Click on the up/down arrow selector
- Select "Clear File History"
Built For:
Simulator - 2.2.1
XCode Version:
3.1.4 (Which includes OS3.1 Beta 3)
I had the same issue last night, and suddenly my system got reboot. At that moment, i was trying to install an application into simulator. When system returned, and i tried again to install the app, it said, "Failed to launch simulated application"
Than i did googled it, and tried many solutions, like cleaining all targets and try building again, but didn't worked out.
So i have found the following link, where it is described, how to reset the iPhone Simulator contents:
http://developer.apple.com/iphone/library/documentation/Xcode/Conceptual/iphone_development/125-Using_iPhone_Simulator/iphone_simulator_application.html
I tired doing it, and you guys would'nt believe me, it worked :) ,
Solution was : "To set the user content and settings of the simulator to their factory state and remove the applications you have installed, choose iPhone Simulator > Reset Content and Settings"
Best of Luck to all.............. :)
This ends up being a product name issue:
The fix is to revert back to
${EXECUTABLE_NAME}
${PRODUCT_NAME}
for the executable file and com..${PRODUCT_NAME} in the info.plist.
Clean XCode, Quit, rese and quit simulator and you're good to go.
found some wierd log in /var/log/system.log.

Here is a discussion about how to run app in simulator via command line, hope it helps to understand how does xcode and simulator works.
But I didn't work it out.
Well, I "solved" it by install another distribution of hackintosh(IPC 10.5.6), works perfect!
In my case, I was adding a target to an existing app that had always worked. In my case, I had forgotten to select all the source code, xibs, frameworks, etc. and click their target checkbox. My clue was that the build happened instantaneously, which didn't make any sense. It never built anything. It just failed to install in the simulator. Once I included all the source files, etc., for the new target, then it built and installed fine.
I had the same problem, I fixed it by launching the simulator through another app and deleting the app I was trying to run on it. Then try to build and run and worked perfect.
Cheers
Matt
I had the same problem. I had accidentally added my info.plist file to my target and it was getting copied to the app bundle every time I built the application. So there were 2 .plist files in the bundle - mine and the Info.plist, created by XCode - which confused the simulator.
Simply delete the app from the simulator (and/or device if you're attempting to run on your device) via the UI of the simulator, then shut the simulator down and attempt to re-run the app. Doing the deletion of the actual files backing the simulator will also remove the app and do the same thing (but the deletion via the simulator's UI, if it works for you, is a little bit faster and easier).
Is your CPU Intel, and, of a model distributed in Apple hardware?
I doubt the Simulator will work reliably (if at all) on non-Intel CPUs and/or in VMWare. The simulator is very CPU specific in order to reflect the arm hardware of the iPhone.
The SDK ONLY supports Intel hardware from Apple.
There is a significant effort involved in creating the simulator and it's not easy or cheap (read, thousands of man hours) to support every CPU.
I fixed this problem by removing the "Icon already includes gloss and bevel effect" property from the Info.plist file in my project.
My problem centered around a Product Name the simulator simply wouldn't accept. Picking alternative names got me past the problem. Changing the name back to the original suspect choked the simulator every time.
Try moving the project to your local hard driver and opening it from there! That solved the issue for me (the project used to be stored on a samba share).
My fix:
restarted the Mac and it was fixed. (before that tried clearing caches, deleting caches from iPhone Simulator, cleaning, rebuilding, quitting OS, quitting Simulator, nothing worked.) Restarting the OS worked.
This was bugging me too but finally got it working.
Unfortunately, I can't reproduce what I did it but here's my list of actions for your information.
The project causing the problem was one I'd downloaded from Apple and tweaked.
Interestingly, I could still launch my own projects fine.
So, here's a list of actions that I did (note that none of the actions below worked just by itself):
- closing the simulator and doing "clear file history"
- restarting simulator
- rebooting
- restarting xcode
- resetting the iPhone with Reset Content and Settings
However, by the time I'd tried all of the above with a fresh version of the code I'd downloaded - it was working again. Just out of interest, I dragged the project that was causing this problem back to the desktop and it was OK now.
Wow, what a pain. I had to uninstall XCode 4 via the command line and then install XCode 3 again. Make sure that you restart after you reinstall. Working...
why anybody didn't tell about restarting simulator.
In my case,
Resetting the iPhone with Reset Content and Settings
and
**ReStart Simulator**
works well~
I had the exact same problem - I reset the iphone simulator and then quit the simulator then started it again.
