In my app, I use a very large amount of code that I copied from Apple's SpeakHere example, and when I run the app on an iPhone device it spits out this error about a hundred times before loading the XIB:
unable to read unknown load command 0x80000022
It also prints these errors:
warning: Unable to read symbols for ""/Users/eamonford/Desktop/Sleep Blaster touch/build/Debug-iphoneos"/Sleep Blaster touch.app/Sleep Blaster touch" (file not found).
warning: Couldn't raise load state for requested shlib: "Sleep Blaster touch" for breakpoint 1.
However, when I run the app in the Simulator there are no errors at all. Also, I know the errors are coming from some part of the code that I got from SpeakHere, because Apple's own example produces the same errors, and my app didn't produce these errors before I added the SpeakHere code.
Does anyone have some idea of what these errors mean or how I can trace them? Thanks!
Regarding the first warning, this appears to be a known issue in SDK 3.1 (I'm assuming you're using 3.1, I'd never seen this error with other versions). If you try compiling with a 3.0 target, that should resolve it.
I saw this error after upgrading to Snow Leopard, but before upgrading the Developer tools.
If you haven't already, go download and install the new Xcode and SDKs.

This bug is really confusing me as it only happens on 1 of the test phones I have. When loading a UIWebView in my app it starts to kick these warnings out into the console and never finishes loading the site.
warning: Unable to read symbols for /Users/internet/Library/Developer/Xcode/iOS DeviceSupport/5.0.1 (9A405)/Symbols/System/Library/Extensions/IMGSGX543GLDriver.bundle/IMGSGX543GLDriver (file not found).
warning: No copy of IMGSGX543GLDriver.bundle/IMGSGX543GLDriver found locally, reading from memory on remote device. This may slow down the debug session.
I have looked at a few things like warning: Unable to read symbols but nothing has really helped me with this problem. I have done a clean build command+shift+K, but that doesn't do anything ever.
Anyone help?
The phone is an iPhone 4S on iOS 5.0.1
Maybe this will help:

I have spent quite a while on this issue. I haven't found a proper answer.
I upgraded my Xcode to 4.0.2 and sdk to 4.3. When I run my application on Device, 2 warnings appeared:
warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J2)/Symbols/System/Library/Frameworks/IOKit.framework/IOKit (file not found).
warning: Tried to remove a non-existent library: /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J2)/Symbols/System/Library/Frameworks/IOKit.framework/IOKit
I have tried to remove the entire directory of 4.3.3 (8j2) and re-fetched again in Organizer. However it didn't help at all.
I have IOKit file under /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J2)/Symbols/System/Library/Frameworks/IOKit.framework/Versions/A, after I copied the IOKit from directory "A" to IOKit.framework , the first warning gone, but the 2nd one still remained, and i do not think it is the proper way to solve this issue.
Anyone got any clue?
Thanks a lot!
It's just the debugger complaining, and unlikely to affect your debugging unless you're working with IOKit directly.
This won't stop the code from working, but I would report a bug to Apple.
I've run this app on my iPhone before, and I have no idea how it randomly started not working, but I'm getting the following error:
Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).
So, I cleaned all targets and then deleted the app on my device and reinstalled it and ran it, and now I'm getting this error:
warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/info/dns.so (file not found).
What is this and how do I fix it?
Well, I have the same problem but it only disables debugging (doesn't find the debugger symbols of the version installed on the device). Except debugging, It installs the app normally.
I know few people who got rid of these warnings by doing any of the following two :
1) copy the 4.2.1 symbols folder from the /Developer/Platforms/iPhoneOS.platform/DeviceSupport/ path to the symbols fodler in 4.2.1 (8C148) folder
2) Look at this one
Universal fix is: 'Clean all' in your project, delete app from device. Rebuild.
Are you targeting the same version that you're running on the device? Check this, then clean, delete from app, and rebuild.
Probably a silly question. When running my project on the Device in the debug mode I get a lot of warnings al having the following string:
warning: Unable to read symbols for
/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1
(8C148a)/Symbols/System/Library/PrivateFrameworks/
I think its due to the space between "4.2.1" and "(8C148a)". How can i get rid of it? It must be a setting somewhere in Xcode.
I dont have these warnings on the simulator.
thanks in advance, Christian
I was getting:
warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/info/dns.so (file not found).
Version 4.2.1 does not include 'info/dns.so'. At least that was the case for me. However, it does exist in the 4.2 directory and is pointed to by the /DeviceSupport/Latest shortcut. I simply copy-pasted 'info/dns.so' to where the debugger was looking for it and that seemed to fix the warning.
I had this issue with 4.2.1 (8C148a), which I believe is caused by differing DeviceSupport files on the phone and in XCode. I tried many things, but eventually resolved it by deleting this folder:
/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148a)/
After this I plugged in my iOS device and was asked to connect and restore the symbol files from the device, and it worked normally again.
When you plug an iOS device (iPad) with a slightly newer OS than the the ones in the SDK, a button to download new symbols should appear in the Organizer window of Xcode. Hit it and wait.
I've seen errors like that when my device wasn't on the same version as what I was building for. Are you sure you're not on a 4.2 beta?
I don't think 8C148a is "final"; final builds numbers never seem to end in a letter (my phone is reporting "4.2.1 (8C148)"). I haven't debugged apps on it yet (I got bored waiting for it to extract symbols and went home).
4.2 GM was 8C134, so you're certainly running newer software, but something somewhere is getting the build number wrong.
But I digress.
What directories are in /Developer/Platforms/iPhoneOS.platform/DeviceSupport? If "4.2.1 (8C148a)" doesn't exist but "4.2.1" does, you might have luck doing something like this in Terminal:
cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport
ln -s "4.2.1" "4.2.1 (8C134a)"
Equivalently, if "4.2.1 (8C148)" exists, do something like this instead:
ln -s "4.2.1 (8C148)" "4.2.1 (8C148a)"
You can generally use this trick to get Xcode to talk to a beta device without installing a beta SDK; this is useful if your company has some people running the beta (for testing purposes) and other people on the latest "final" (for release purposes).
There's a mismatch at the moment, where the released version of 4.2.1 is ahead of the SDK version 4.2
#Khrob's comment fixed it for me though!
Until they provide a solid SDK, a cool workaround is to :
1 - select the Executable ( In 'Executables' in the project browser ),
2 - get info and turn off "Break on Debugger() and DebugStr()"*
Cheers, and best wishes for 2011.

This does not disable NSLog.
I have 4.2.1 on an iPhone 3G and Xcode 3.2.5 running on a MacBook Pro with 10.6.6. After a clean install of Xcode, I was getting the prompt to download symbols for 4.2.1 after plugging in my iPhone. After the transfer, I would no longer get the prompt when attaching the iPhone, but I was getting tons of "unable to read symbols" messages.
First, what did not work for me:
Creating symbolic link to '4.2 (8C134)' with the name '4.2.1 (8C148)'
Creating symbolic link inside directory '4.2.1 (8C148)' like there is in '4.2 (8C134)' to the ../../Developer/SDKs/iPhoneOS4.2.sdk
Both of the above caused the 'UUID mismatch' errors for several libraries. GDB would start but appear to hang.
Finally, what is currently working for me:
% cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport
% mkdir '4.2.1 (8C148)' # if it does not exist
% cd '4.2.1 (8C148)'
% cp ../4.2\ \(8C134\)/DeveloperDiskImage.dmg* .
% cp -r ../../Developer/SDKs/iPhoneOS4.2.sdk Symbols
Attempt to run debug session for an application and watch the Console. For each warning about a UUID mismatch, remove the file indicated in the log message (I had AudioToolbox, CoreMedia, and some others)
Stop GDB and try again, hopefully with success
At least for my application under development, everything now works fine. Hopefully, Xcode 4.0 will clear this up.
Since upgrading to Xcode 3.2.1, I've experienced a strange issue that has really killed my workflow. The issue only exhibits itself under my own user account (the same project opened by a different user works fine). Therefore, the heart of this question is, "what does Xcode load from the user directory that could conceivably cause this issue?"
(System: Snow Leopard 10.6.1; Xcode 3.2.1 w/ iPhone SDK 3.1.2)
Symptoms:
Code completion only works on symbols of the current class or already referenced in the class. Virtually useless.
Document/reference lookups (i.e. option-double-clicking on an identifier or symbol returns this strange result): "Documentation not found for the symbol 'symbol name'. Click here to view symbol declaration."
Like I said, since other users are experiencing normal behavior in Xcode, this must be due to something only loaded for my user account. I've already eliminated ~/Library/Preferences/com.apple.Xcode.plist, ~/Application Support/Developer,~/Application Support/Xcode`.
The only thing I've recently installed is mogenerator (the defunct xmod integration may have killed it, but it doesn't install anything to the user directory)
Update: 10/26/09
This one is really starting to kill me. I did a fresh OS X install, followed by an Xcode 3.2 install from the Leopard disc, followed by an iPhone SDK install from the ADC site, and this started occurring again within 30 minutes of my having started working. I'm at an utter loss. The error is most obvious when option-double-clicking on a symbol (say, the NSString class) and instead of getting the documentation snippet, a message "Cannot determine the symbol for the current selection." appears.
Update: 10/26/09 #2
I just tried creating a fresh project, and that project's symbols are appearing fine. So the issue is apparently local to my project. Hopefully that's a better start. To demonstrate what I'm talking about, here's a screen of the issue manifesting itself with respect to documentation:
Have you tried rebuilding your CodeSense index? Project > Edit Project Settings > General >
alt text http://idisk.mac.com/cdespinosa/Public/Rebuild.png
After doing that, check Console.app to see if Xcode issued any warnings. It's possible that some of your source code causes the indexer to stop, and you don't end up with a valid index. Filing a bug with Apple and providing the source, if possible, would help Apple fix problems like this.
This is the first thing I'd try:

Wait until it doesn't say "Getting" anywhere anymore before doing anything documentation related.
Given the clues from the console:
10/26/09 7:21:58 PM Xcode[19072] Warning: Couldn't discover the 'clang' compiler's built-in search paths and preprocessor definitions for language dialect 'objective-c'. This may lead to indexing issues.
Compiler: /Developer/usr/bin/clang

clang: warning: not using the clang compiler for the 'armv6' architecture
I'm going to say that you tried to configure an iPhone Device build to use the Clang compiler, which is not yet supported for compilation. (It works for static analysis, but not for building).
Find the Compiler Version build setting and set it back to gcc 4.2.
I had this same problem and I was able to workaround it by:
Setting the target to be the iPhone simulator
Quit and relaunch Xcode
Rebuild the index
Clean and rebuild the simulator target
Maybe it's a bug in Xcode with iPhone device selected when a project is first opened.
