I was able to run my projects in iPad and iPhone using the xcode 4.3 till yesterday. But today when I tried, the XCode is not getting connected with the iPad, and it is getting connected with iPhone.
I have checked the deployment target, provisioning profile, all these things are correct, and working fine in iPhone. In the organizer an orange indicator is showing instead of green symbol while connecting. I have restarted both the system and iPad several times and checked, not get solved.
If anybody having idea about this then please help me.
Just upgrade you Xcode or if you have another computer which contains xcode 4.5, detect your device on that computer this will also detect your device on computer with xcode 4.3.
I also had same problem and this works for me.

I updated to the latest AppStore release of Xcode (12.3, 12C33).
It worked fine for an hour or two. After that it started to constantly freeze after being open for a few seconds to minutes.
I've tried the following, all without success so far:
restart macOS
clear derived data
tried with different projects
updating to latest macOS 11
Any other ideas or suggestions how to fix this?
Update
I can confirm that this is fixed in Xcode 12.5
I found an answer by Darr on the question "Xcode freezes after upgrade to 12.3" on Apple's developer forums that worked for me:
Unpairing my device connected via network and using only lightning cable seems to have resolved the issue for me.
Xcode > Window > Devices and Simulators > device > Connect via network
After going mad, I fixed this by removing all devices from Devices and Simulators (I had connect via network activated).
For now, it's working fine.
Power off your Apple Watch
Xcode may hang if the host Mac is connected to an iOS device which has one or more companion watches. The hangs occur when the watches aren't fully prepared for development, or if they are experiencing poor wireless connectivity. (72490921) (FB8945320)
Workaround: Power off the watches, or unpair them from the iPhone.
Xcode 12.4 Release Notes
You can force Xcode to freshly prepare a watch for development using these steps:
Force-quit Xcode.
Power-off and disconnect all iOS device from the Mac.
Reboot the Mac.
Launch Xcode, close all projects, and open the Devices and Simulators window.
Power-on and unlock an iOS device and its companion watchOS devices by entering the passcode as required.
Plug the iOS device into the Mac using USB cable.
Check each iOS device and each watch for any pairing request and approve the requests.
Monitor the status of device preparation in the Devices and Simulators window. If Xcode presents device-preparation errors, follow the guidance in the error message to resolve the error.
Once Xcode finishes preparing the iOS device and its companion watches for development, repeat steps 5 through 8 for each remaining iOS device and its companion watches until you verify that Xcode has prepared all devices for development. You may now open your Xcode projects and resume development.
I've been having the same problem. I had an iOS device connected via USB, unplugged it and it un-froze. Then I continued to have issue requiring force close each time.
I then clear derived data and things have been fine. I opened a StickerPack project and also had the same issue. Clearing DerivedData also fixed it.
Clear Derived Data:
Xcode pulldown menu > Preferences > Locations tab
Click the little arrow next to the path under Derived Data.
Delete the entire folder for you project. It will look like "MyAppName-bwonddotztrgkkfexrjxoncvmjit"
See this explanation about whether it's safe to delete DerivedData for your project.
I had the same problem with appstore version and someone advised to install from site, now it works fine. https://developer.apple.com/download/more/
Disable WLAN on my iMac fixes the problem currently.
Hope they will releast a fix very soon.
Xcode 12.3 is unstable and many times it crashes.
I reverted back to Xcode 12 and copied disk image of 14.3 in Device Support folder of Xcode (Contents > Developer > Platforms > iPhoneOS.platforms-DeviceSupport).
This I needed to debug on iPhone device having version iOS 14.3
https://github.com/mspvirajpatel/Xcode_Developer_Disk_Images/releases
I recently had similar situation. My Xcode 12.3 project could not be opened. I tried to open directly from popup that appears on start of the Xcode.
What worked for my was to downgrade Xcode to 12.2 and launch Xcode on new project. And then click my old one.
Maybe it would work without downgrading but I didn't check.
I had this problem too. I fixed it by going Devices and Simulators in the Windows file and disconnecting the iPhone reference I had for my phone when testing and app. Since the phone was no longer connected, its presence seemed to create a freeze.
In my case XCode 12.5 hangs/freezes on startup more or less instantly, right after it opens kind of an empty workspace.
I removed everything that I could imagine that deals with XCode on my machine, but it didn't help.
At the end I just used the hotkey for "Close Workspace" - Ctrl+Alt+Cmd+W
I hit this combo very often, very fast right after opening XCode and it worked!
The strange empty workspace showed up and closed instantly - now I could select other projects and everything works again.
There could be the multiple reasons and in my case reason was source control
preferences > Source Control > uncheck Enable source control
I have these performance problems with the newly updated Xcode from the AppStore to 12C33 (Xcode frozen for many seconds, instability of interface builder, etc.) only with apps which have frameworks added with cocoa pods and when working in the xcworkspace-file. (Integration of frameworks with Catharge even fail with error message 65). I'm running Xcode under macOS Catalina. Don't know what the technical reason could be, hence would appreciate if someone has an idea on this how to fix it.
Update: In the meantime I could fix it:
I eliminated my own devices from the device list and did then a deintegration and a new install of the cocoa pods for the projects. Afterwards I setup my devices again in the device list and all worked well again. Only eliminating and reintegration of my devices as described above didn't work in my case.
Xcode gives me this message every-time I try running my app on my iPhone. (Works fine on the simulator.) (And this occurs in every project I have.) (I also just downloaded Xcode again.)
This is the message I get.
App Installation Failed.
Unknown Error Occurred.
How do I fix this error?
Unplugging iOS Device and plugging it back it in fixed it for me.
Alright, it was a simple fix:
Go into Xcode Preferences -> Accounts -> More Info. Hit the refresh icon.
Clean your project. Project -> Clean.
Force quit Xcode.
Reboot Mac and Device.
If you have the same App but downloaded from AppStore, I suggest to remove the App manually from your device, then try to run the new version with XCode.
After following the suggestions in this thread (restarting iPhone, cleaning Xcode project, quitting and re-launching Xcode) and others (setting Team to None then back to my Team) and unplugging and replugging Lightning connector from my iPhone 6 I was still experiencing this problem. Xcode would even display an error that my iPhone 6 was locked, even though it was not.
I was able to fix it by unplugging the USB-A connector of the USB to Lightning cable from my MacBook Pro, then plugging it back in. I'm not sure why that made the difference, but glad that it did resolve this annoying problem.
I have this issue regularly. There are a number of techniques that help me overcome it, including the classic "turn it off and back on again."
One thing that isn't mentioned here is that the iPhone should be switched on, unlocked, connected to the mac and then the app should be run (with the iPhone unlocked). Don't lock it!
Make sure your device name doesn't have any emoji (Xcode 11.0)
if you using vpn services, then you need to turn off vpn. Works for me
I just updated my xcode to work with ios7. Now whenever I make a new app, even if its set to build for ios7, I get an error in the simulator when running. It says that the install failed, even if I just made the project and haven't coded anything into it yet. The simulator also shows a black screen. I have tried the reset content, and it didn't work. I saw something somewhere saying to delete the Iphone Simulator folder in application support, but no such folder seems to exist. What can I try to do?
Update--
With some additional research, I found that Iphone Simultor is in the Xcode.app now, but I don't know what to delete. There are many files under the iPhone Simulator Folder. If I delete the actual app, it just doesnt open. Any ideas?? I dont even get an iphone on the screen, just a black window...
Update 2:
Even when I just go to open developer tools -> iphone simulator
it still gives me just a black screen....
Update 3
I just re-installed X-code, and all works now! Strange....I have no idea what happened...But I thought I would let y'all know for others who have similar issues.
Deleting the iOS Simulator folder of the iOS version in question in
/Users/xxx/Library/Application Support/iPhone Simulator
helps, but then you always have to repeat all the settings you made in the simulator (language, for example). Try to press the home button and then delete your app like you do it on a real iOS device. You should then be able to install it again.
This seems to be a known issue.
When simulator open - Go to iOS simulator tab -> reset content and settings..
Work for me.
Perhaps this answer will help?
The simulator should be in this folder:
/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iOS Simulator.app
Make sure any #try and #catch(NSException *exception) {} blocks are not commented or are working properly.
This is a version mismatch between your OS X version and your Xcode (iOS simulator)
and it seems that you have upgraded your OS X so Xcode needs to be upgraded as well, Check the versions that match with each other.
You need to upgrade your Xcode which will upgrade iOS simulator.
Good Luck,
I have been having this Xcode problem for a couple of months where my iOS simulator stops working whenever i run any application on Xcode and says, "The simulated application quit." and "iOS Simulator could not find the SDK. The SDK may need to be reinstalled." I am running Xcode 4.3.3 and have iOS sdk 5.1 and everything updated but it happened on my previous version of Xcode also. I have tried reinstalling Xcode over 10 times now and have been posting this question for a while now. No one has been able to get a solution. I have even sent in a bug report to apple but i don't think they will respond. I have tried doing everything every other person that has this problem has been told to do in other threads. I'm honestly thinking about just buying a new mac and seeing if Xcode will work on that one or taking in my current one to get looked at by apple. So if anyone has any ideas please let me know.
Go to Xcode -> Preferences -> Downloads and make sure the "Target SDK" you have selected in your project is in fact installed under the Downloads windows. For me this magically was uninstalled. Once i installed the SDK that my app was using, all worked again
This worked for me: http://www.colinbowern.com/posts/the-simulated-application-quit
I just deleted the folder "6.1" under ~/Library/Application Support/iPhone Simulator
The I just launched again the app and the simulator recreated correctly the 6.1 folder.
Resetting the simulator settings (iOS Simulator > Reset Contents and Settings) resolved this issue for me.
I had the same issue. For me suddenly all the installed simulators (4.3 through to 6.0) stopped working. I then went to Xcode -> Preferences -> Downloads, and there I had the chance to update at least the 5.0 simulator. This is now working, yet I was not able to get the 4.3 or 5.1 or 6.0 to work.
I have personally experienced a weird thing with xcode regarding this issue. Sometimes the sdk is installed properly but it still gives this error. I have two classes, if I call first class from the app delegate then the ipad simulator works fine but when I call the second class then it gives the error that the sdk needs to be re-installed.
In my case when the error occured, I had two errors in the second class. When I corrected the errors after debugging, the ipad simulator started to work completely fine. This is quite weird but its not the problem with your sdk, the problem is somewhere in the code.
This just happened to me. I tried to launch with iPhone 5.1 Simulator, got the error "iOS Simulator could not find the SDK. The SDK may need to be reinstalled." I tried running iPad 5.1 Sim, which worked. I switched to non-retina iPad. Then I tried running iPhone 5.1 Simulator again, and it worked.
My iphone simulator just doesn't work anymore,whenever i click on build and run i just get nothing but i can see IOS simulator and all of its related options at the top bar (next to the Apple menu),now if go to the Hardware option and change the device to Ipad Or Iphone(ratina) they come on the screen with no problem,its just the normal iphone which wont come at all.
While compiling i dont get any errors or warnings at all ,this problem just started occurring from today morning till last night everything was just fine Xcode version is 3.2.5 .
Thanks.
You should check your iphone-simulator-folder and verify that the IOS-Simulator.app exists
/Developer/Platforms/iPhoneSimulator.platform/
Otherwise update your SDK, this should solve the problem
