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.

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.
According to the documentation should be able to choose which iOS version the simulator should run, however only the latest 4.3.2 is listed under "Hardware/Version".
The helps says:
"To set the iOS release used in the simulation environment, choose Hardware > Version, and choose the version you want to test on."
I don't want to support 3.x (although it would be nice) but at least I want to simulate my app on 4.2, 4.1 and 4.0.
What's going on? Why aren't they listed?
UPDATE:
I'm on Lion so I cannot install an earlier version of Xcode. Before my Upgrade I could test different versions easily.
the problem is that you have no other Simulator SDK installed which can be used. As #dorada has mentioned you have to install an older Xcode which in fact doesn't work because you're using Lion. I haven't tried it with Lion but principally it should work like before with Snow Leopard.
I'm referencing to my other answer how to get an older Xcode (don't know if it's still working)
After you have an older Xcode version, mount the image an navigate with terminal to that volume. There should be a hidden folder Packages. open that folder with open . and locate the two .pkg files you need (e.g. iPhoneSDK4_0.pkg and iPhoneSimulatorSDK4_0.pkg) and install both.
They will appear in your root directory and you have to move them to your Developer dir (don't simply overwrite, it will delete all other SDKs. go to the last different folder it should be iPhoneSimulator4.0.sdk\ and copy that one)
DONE (and at that point I have verified it: it works on my Lion. I used the dvd image which I have started backup'ing since 3.2.1)
Although iPortable has the correct answer I decided to post a step-by-step guide which is easer to follow:
Download Xcode 3.1
Mount the dmg file
In Finder menu select "Go\Go to folder" and enter "/Volumes/Xcode and iOS SDK/Packages"
Install the simulators you need (Double click)
Copy the simulation folders from /Platforms/iPhoneSimulator.platform/Developer/SDKs/ to /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/
If your have some SDK missing Install the missing SDK from "/Volumes/Xcode and iOS SDK/Packages" and copy subfolders from /Platforms/iPhoneOS.platform/DeviceSupport/ to /Developer/Platforms/iPhoneOS.platform/DeviceSupport/ (for me they were all there from 3.1 to 4.3)
you may download the older ios sdk / xcode from . https://developer.apple.com/downloads/index.action
(i found this answer in another stack overflow topic actually, but now i can not seem to find that question!)
Open Xcode and in the menu at the top left, where you select what device to run on, click "More Simulators..."
The download section of Xcode preferences will open,
Click the "Components" tab.
You will see a list of simulators that can be installed, click install on version you need.
The simulator will need to restart to install.
To run the newly installed version of the simulator just select it from the run menu in Xcode.
You actually have to install previous simulator versions, they aren't there on a new install.
Maybe you can search and download them somewhere? - we keep them on a shared drive at the office.
After installing the Xcode 4.2 for Snow Leopard, I noticed there was a choice for iPad 3.2 Simulator, but using it just brings up some alerts that say "iOS Simulator could not find the SDK. The SDK may need to be reinstalled." and another alert that says "Simulated application quit. Click Relaunch to try again." with Quit, Switch SDK, and Relaunch buttons.
I can successfully use iPhone 4.0 Simulator, iPhone 4.1 Simulator, iPad 4.2 Simulator, etc up to iPad/iPhone 5.0 Simulator, but really would like to have iPad 3.2 Simulator and iPhone 3.1.3 Simulator and earlier down to 3.0 if possible.
Our apps generally run all the way back to 3.0 and we occasionally receive bug reports from earlier iOS users, and would love to be able to debug these issues more effectively.
I tried the technique summarized by Tibidabo and although I am able to copy the simulator folders as mentioned, and though they show up as choices in Xcode, I cannot get them to actually run as simulators and I get the same problem alerts mentioned above.
What are other developers doing to support debugging of older iOS versions?
Go to Project Settings -> Summary an change Deployment Target.
I recently installed XCode 3.2.4 to my machine. This comes with iOS SDK 4.1. Annoyingly I can no longer install my app to any iPhone. The option to tick "Device" in the drop down for where to install to is present, but when I click it, it doesn't become ticked. Strangely I can only run my app on the simulator, despite the option to select the simulator not being present.
Does anyone know how to fix this or what might be the problem?
Thanks in advance,Tristan
Alrighty, I'm answering my own question.
What I didn't realise is that there's seperate build configurations depending on wether you click 'info' while selecting your project's title or the project's Target. I had set the project one to SDK 4.1 but not the Target one.
Did you set the iOS Deployment Target in your Debug or Release Build Settings to match the OS version on your iPhone? Did you set the Targeted Device Family to iPhone?
All these questions just remind me that something is very confusing in xCode.
And don't let me start talking about all the provisioning misunderstandings
I've installed on my MacPro (intel) Xcode 3.2.1 (iPhone SDK 3.1.2) and Snow Leopard
I made a new project (called Untitled) for iPhone OS, when I try to build, it returns an error:
*file not found:
*/Users/user/Documents/Untitled/build/Untitled.build/Debug-iphonesimulator/Untitled.build/Objects-normal/i386/main.o
*/Users/user/Documents/Untitled/build/Untitled.build/Debug-iphonesimulator/Untitled.build/Objects-normal/i386/UntitledAppDelegate.o*
*Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1*
and doesn't go over!!
what i've to do to fix?
thank you for your answers
"Untitled" is a common place holder so it's possible that the using that as the project name has caused a problem with one of the build scripts. Try another project with a more unique name.
Other possible problems: (1) Permissions problem with the build directories (2) if you messed with the build settings you might have switched off the creation of the executable.
Edit01:
(Response to comment)
It sounds like you have a nasty corruption problem for some reason. Some things to try.
(1) Create a new user and try to run Xcode from that account. That will tell you if the problem is with the developer install or if its some kind of preferences or other file in the user's home directory. Xcode and the other dev apps dynamically create a lot of directories and files that an reinstall will not affect.
(2) You can do a complete uninstall of the developer tools from the command line.
sudo /Developer/Library/uninstall-devtools --mode=all
(3) Xcode is just a face application for a full suit of unix command line development tools. If you installed different versions of these tool e.g. gcc, gdb etc, you might have altered something critical.
(4) Xcode plug-ins can cause problems. Make sure you remove all of them.
I had a crash in Xcode once, and afterwards I could never get Xcode to run under that user account. I spent nearly two days trying to troubleshoot before giving up and moving to another account. That turned out to be a good thing because it allowed me to create an account focused solely on development without all the distractions of my normal account.
Doesn't Xcode 3.2 (not 3.1.2) ship with Snow Leopard? If you're using Snow Leopard, you should be using the appropriate version of Xcode for Snow Leopard, which is the 3.2 series.
I am getting an error while uploading my app on device. It does installs it but not able to upload it.
Also I want to run the instrument tool on device but when I run it shows nothing.
Anyone facing the same issues.
I had this problem after changing around provisioning profiles and app ID's.
What fixed it for me:
Quit XCode
In Terminal.app, navigate to your project directory and execute rm -rf build/
Restart XCode
I also confirm, that I had that issue on Xcode 3.2.5 and iOS 4.2 GM Seed and after adding new provisioning profile.
You do not have to use terminal, you can select *.app from Products Group in 'Groups & Files' pane in Xcode. Then right-click on it, and select 'Reveal in finder'. Then manually delete the build catalogue. And restart Xcode.
Worked for me.
I was getting this issue on an iPhone running 3.0 software, but it was working fine on phones running 3.1. The app used to work on the 3.0 software until we added users to the provisioning for the app - this is the only thing I can think of that might have caused it.
If you're running 3.0 still, try upgrading to 3.1 and see if that fixes it.
I had the same error message in iOS 4.1 but from a different cause: when trying to link to a universal (ARM & X86) static library that was over 10MB. If I link directly to the ARM version of the static library (for iPhones), then it works fine.
Sometimes manual delete of Build folder of your application fails to solve the problem
"Failed to upload the .app on device"
Try
WIndows->organizer->Provisioning profile(in left pane)->refresh it once....
This has solved my problem!
