I am getting an Error on the top of my interface builder in Xcode 10.3 and while clicking on report bug and checking the log.txt file I found out that fails to open simulator. However I am not starting any simulator.
Here is the Error found in Log.txt
Encountered an error communicating with IBAgent-iOS. (Failure reason: IBAgent-iOS failed to launch): Failed to boot device iPhone Xs (0B8270CC-2BFB-4BB6-90A5-6BA61468A1AD, iOS 12.4, Shutdown) for context <IBCocoaTouchToolLaunchContext: 0x7fe80e754ad0> toolName = IBAgent-iOS, description = <IBCocoaTouchPlatformToolDescription: 0x7fe80e2a0290> System content for IBCocoaTouchFramework-ElevenAndLater <IBSimulatorDeviceTypeDescription: 0x7fe80fab2f90> deviceType=com.apple.CoreSimulator.SimDeviceType.iPhone-XS (Failure reason: Failed to boot iPhone Xs (0B8270CC-2BFB-4BB6-90A5-6BA61468A1AD, iOS 12.4, Shutdown)): Unable to boot the Simulator.

If anyone still looking for an answer to this after Xcode 13 update, I have tried everything they mentioned on the internet and nothing worked except one. The only thing that worked is the complete re-installation of Xcode. Completely uninstall/delete Xcode first and restart the mac and reinstall Xcode then all should be good.
Delete Xcode from Applications Folder and Empty Trash.
Go to ~/Library/Developer and Delete CoreSimulator, Xcode, XCTestDevices Folder. Empty trash
Goto ~/Library/Caches and delete everything starting with com.apple.dt.Xcode, Empty trash
Then Restart your Mac and reinstall Xcode. I used my downloaded Xcode app, AppStore installation will also work, I guess.
Now it all working.
Before that, I have changed the storyboard file using Open as Source Code mode (coz I couldn't open it in Interface Builder - Xcode just hang)
I changed the storyboard design device to iPhone 13 instead of the older device version it had.
<device id="retina6_7" orientation="portrait" appearance="light"/>
I change the existing line with this line. It kinda solve another issue of Xcode hanging, when trying to open with Interface Builder, but it didn't solve Encountered an error communicating with IBAgent-iOS issue when trying to install the app. That issue only got solved when I completely reinstalled the Xcode.
I have managed to fix it just by changing preview device on interface builder
In my case it helped:
clean project
remove derived data
close Xcode
restart Mac
I used DevCleaner XC helper app:
https://apps.apple.com/us/app/devcleaner-for-xcode/id1388020431?mt=12
removed everything, and after that restarted mac. No XC reinstall needed.
This problem caused because, I deleted all directories under "Library/Developer/Xcode" for a purpose. But, I realised I also deleted wrong directories in same time. Then I put back directories from the Bin. It is solved for me.
If you have or have had multiple versions of Xcode open, you may need to reboot or completely re-install the CoreSimulatorService, an evil, globally installed background service that somehow remains online and available to many versions of Xcode despite it being compatible with only one version.

Other symptoms of this issue: Simulators not showing up in the Window > Devices and Simulators listing and simctl throwing errors and being unable to find base iOS SDKs similar to the following:
$ xcrun simctl list
...
-- Unavailable: com.apple.CoreSimulator.SimRuntime.iOS-15-5 --
iPhone 8 (55A90310-8202-4A0D-968B-00F440D42210) (Shutdown) (unavailable, runtime profile not found)
See also:
Command CompileAssetCatalog failed with a nonzero exit code
Xcode device Unavailable, runtime profile not found
In my case, I just had to set team in
Project > Targets > Signing & Capabilities > Team > Personal Team
So after spending hours sweeping the web for answers, the recommended solution to this problem was to go to XCode.app/contents/developer/platforms/iPhoneOS.platform/DeviceSupport and then delete the directory that matches your device's iOS. Which I did and I got the following results:
BEFORE DELETING THE DIRECTORY "iOS11(15A372)"
Error Message: dyld_shared_cache_extract_dylibs failed
AFTER DELETING THE DIRECTORY iOS "11(15A372)"
Error Message: This iPhone 6s is running iOS 11.0 (15A372), which may not be
supported by this version of Xcode.
Help!
please follow the following step.
step 1- Download file that you need below:
iOS 11 beta
step 2- Copy this iOS 10.2 image file to: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
Restart Xcode.
Now it Working fine.
Hope it works.
I want to play Flac files in ios and downloaded code from: SFBAudioEngine
I added frameworks for mac os and it build successfully but when I run app it crashes and gives
dyld: Library not loaded: #rpath/dumb.framework/Versions/A/dumb
Referenced from: /Users/Library/Developer/Xcode/DerivedData/SFBAudioEngine-frrtbwxsqekjtmekpdfikqaqcsso/Build/Products/Debug/SimplePlayer.app/Contents/MacOS/SimplePlayer
Reason: image not found
And When I am trying to make build for ios app It is giving error
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/libtool failed with exit code 1
Please help me to run this app .
It looks like the dumb framework is not being loaded. You need to make sure it's located at this path on your computer:
#rpath/dumb.framework
And make sure this file exists before running your app:
#rpath/dumb.framework/Versions/A/dumb
Just put the Frameworks folder inside the SFBAudioEngine folder. check for #rpath details
I have two Xcode installed on my iMac (OSX 10.6.8), Xcode 3.1.4 and Xcode 3.2.6.
I created a new „empty view” project, it builds and runs in simulator fine with both Xcode.
BUT when I want to build to DEVICE then I got this error in Xcode 3.2.6:
.../build/Debug-iphoneos/JustaTest.app: object file format invalid or unsuitable
Command /usr/bin/codesign failed with exit code 1
It still works fine in Xcode 3.1.4 but it seems that the JustaTest.app file generated by Xcode 3.2.6 is not compatible with codesign.
Does anyone know how to tell Xcode 3.2.6 to generate codesign compatible app file?
Or how to get a new codesign which can sign app files generated by Xcode 3.2.6?
Thanks a lot.
H everyone
i have up graded my xcode to xcode 4 & i am trying to install a app through this xcode on to a iphone but i am getting following error & i am unable to launch the app

i have following warning in my app
ld: warning: directory not found for option '-F/Developer/new xcode/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/System/Library/PrivateFrameworks'
is from this warning
how can i fix this?,,,thanx in advance
you have to check that all images and framework are included friend. may b any image is missing that is deleted from project folder .check if you get any image in red then add that image
Looks like your app is still trying to link to the 3.1.2 SDK. You need to change the SDK in the project settings to Base SDK: Latest (iOS 4.3). Also make sure to clear out any settings in the target for this value so that it inherits it properly.
