I have a source code of a swift application which developed for iOS using swift 3.
I want to run it inside Xcode however it remains in loading state forever.
I have tried solutions provided in question Xcode freezes on startup while loading project however the situation did not change.
The developer of this source code told me that he used Xcode 9.x to develop application so he suggested me to try a 9.x version of Xcode. I guess Xcode should be backward compatible however I want to know does using Xcode 9.x changes the situation or I should look for reason somewhere else?
Using answer in apple.stackexchange.com did the trick:
Removing the ~/Library/Saved Application
State/com.apple.dt.Xcode.savedState/directory might help.
I tried all the solutions outlined here and none of them worked. However, I managed to fix this issue and here is what worked for me: If you're on an Apple OS and have iCloud sync enabled on your desktop/documents/any folder where you're loading Xcode from, the iCloud sync could be causing this issue.
I installed a fresh copy of my RN project in a directory not synced by iCloud and subsequently the issue was resolved; my build-time was down to a couple of seconds!
rm -rf ~/Library/Developer/xcode
in terminal worked for me, based on this answer
As of July, 2022, nothing else worked for me but, taking my project outside of the iCloud Drive and putting it into a directory without it. As it is mentioned above, iCloud sync interferes with the XCode running and stalls it.
I wasted almost 2 hrs and tried everything on stack over flow
SIMPLE SOLUTION
Just turn OFF icloud from your mac os so that it it will not sync the project.
To turn off icloud
Go to setting
Icloud
turn off sync
Thats all enjoy
I tried to delete:
~/Library/Developer/Caches/com.apple.dt.Xcode
~/Library/Developer/Xcode/DerivedData
~/Library/Developer/Saved Application State/com.apple.dt.Xcode.savedState
~/workspace/MyProject.xcodeproj/project.xcworkspace/xcuserdata
and once it helped. But another time it didn't help, so I also tried to reinstall Xcode, which also didn't help.
It turned out that the problem was that I was installing the app via WiFi or Bluetooth. When I connected my device via cable, the Xcode popped up to life and the "loading forever" stopped.
My xcode got hang when I force quit it. After that it was showing only "loading".
Here is fix to start xcode from beginning.
cd /
cd Applications
cd Xcode.app
cd Contents/MacOS
sudo ./Xcode
it will open xcode default window to open a new project.
Command/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
failed with exit code 10
I am facing a strange issue. I haven't changed anything but my project is not able to build any more for some reason.
This happened as I changed from Simulator to my phone (which I do really often) after the newest iOS Update.
The below errors came up all at once.
I tried everything from cleaning the project, restarting Xcode, reinstalling/updating pods, using different simulators and reattaching the iPhone new.
Any idea?
I had a similar issue. Go to preferences -> Location -> derived data -> and the remove the derived data or give a custom location. Worked for me.
I had the similar issue suddenly, I closed everything then restart mac, then it worked
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.
A friend of mine just had to reinstall his OS (after power went down while updating) and when he installed Xcode he got this error. In the drop down that usually has device/simulator etc, it said 'missing'. I also noticed he had no developer folder on his machine as well. Anyone know why this might be?
Tell me about it. Try this
in XCode goto 'Project' Menu and select 'Edit Project Settings'. In the General tab, last but one item, select the drop down list 'Base SDK for all Configuration' There you can specify which SDK your project will target.
I had this problem after installing the Xcode that comes with Snow Leopard. To solve it I downloaded Xcode for iPhone. The Xcode that comes with Snow Leopard does not include the iPhone SDK.You have to be a registered iPhone developed to use it.
I had him reinstall it with me there, and I noticed that the action for the developer tools, was install as opposed to upgrade, and it was grayed out so not sure how he would have been able to avoid that. In any event he reinstalled and got the same error when launching from the dock. He then launched from terminal and it worked fine... so somehow he got two installs or some weird scenario. In any event we found the .app that spotlight saw and put it on the dock and then it worked.
The system does not include the dev tools (and hence the /Developer folder) by default. He needs to re-install the dev-tools from his CD (or from developer.apple.com), and also re-install the iPhone SDK (only available on developer.apple.com).
EDIT: I didn't see he re-installed XCode. Sounds weird. Make sure you re-install everything, and that you have the correct rights. However, is no issue is found by the installer and you still don't have a /Developer directoty, there might be something weird going on...
After Xcode updated to Version 11.6 got this error.
error: There is no SDK with the name or path '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator13.5.sdk'
Looks like iPhoneSimulator13.5.sdk got removed.
Fix by downloading "iOS 13.5 Simulator"
In Xcode -> Preferences -> Components downloaded iOS 13.5 Simulator again.
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.
