Hi i'm trying to integrate BoldChat framework into IOS react native project.
After integrating via following steps
Project target -Build Phases - Link binary with libraries - Plus
button - framework
While trying to build, im getting below error
Undefined symbols for architecture x86_64:
"_utf8_nextCharSafeBody", referenced from:
-[BC_SRWebSocket _innerPumpScanner] in VisitorSDK
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I tried removing ,re-adding framework , it's not working.
Even tried creating new project and integrating , still error is same.
please let me know how to resolve this. I have even tried similar stack overflow answers, still error exists.
In most cases this points to one or more missing references to frameworks in the section Linked Frameworks And Libraries in the Targets settings of the app in Xcode.
To find out which framework reference should be added:
Right-click on the error in the build time errors
list Choose 'Reveal in Log',
Search in the log for 'Undefined symbols for architecture x86_64'
A list of undefined 'symbols' (mostly class methods and properties)
is displayed
To find out which framework reference should be added, select such
undefined symbol, right-click and choose Search with Google
In most cases you'll end up in the documentation of Apple, which
should give a clue about the related framework
Add the framework in the section Linked Frameworks And Libraries by
clicking on the + button.
Build the app.
If necessary, repeat this procedure for remaining undefined
'symbols'.
In my case libucucore.tbd is missing . Added that and error is gone.
I have an Swift Framework which works perfectly inside Swift Projects. Now I am trying to use it inside of Objective-C project.
Iv'e Change the Class to looks like:
#objc public class Test : NSObject {}
I imported the framework to the Objective-C project, added it to the Embedded Binaries and to the Linked Frameworks and Libraries.
In the ViewController.m I imported the framework like this:
#import <SwiftFramework/SwiftFramework-Swift.h>
And I try to create instance of type Test:
Test* test = [[Test alloc] init];
Test is recognize but when I try to build it to iPhone it's failed with the reason of:
Undefined symbols for architecture arm64: "_OBJC_CLASS_$__TtC14SwiftFramework4Test", referenced from:
And if I build it to a simulator it failed with the reason of:
Undefined symbols for architecture i386: "_OBJC_CLASS_$__TtC14SwiftFramework4Test", referenced from:
I've tried to add the i386 and arm64 to the Valid Architectures,
I've tried to change the Build Active Architecture Only to No.
I've found a lot of solution which did not help me solve the issue.
I'll appreciate any help, Thank you.
SOLVED:
Build Setting -> Build Settings -> Always Embed Swift Standard Libraries -> YES
I updated the framework and the Objective-C project.
I get the following Linker Error in Xcode 6.1 only, Xcode 6.01 works fine:
Undefined symbols for architecture x86_64:
"__TWvdvC7Bamberg18TourViewController2mmT_", referenced from:
__TFC7Bamberg18TourViewControllerm2mmT_ in tours.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Now I am aware about the standard suggestions. I have tried exhaustively:
cleaning project & build folder
deleting derived data in organizer & developer folder
deleting previous version of the App from simulator and device
resetting simulator
setting "Build Active Architecture Only" to Yes/No
playing around with compiler and architecture settings
adding every single framework that is imaginably (including adding them all)
make sure all implementation files are included in "Compile Sources"
I even recreated the entire project in XCode 6.1 to make sure its not some hidden buggy derived data issue
Finally, I managed to point the source of the problem to an imported Objective C class, which is properly bridged - the error is gone when I do not make use of this class:(https://github.com/mrcrow/MRoundedButton)
If I directly open the demo project of that class in 6.1, it works fine. So I reckon it must be either a conflict of that class with my specific code while being bridged or a bridging error of that class with swift code in general.
Any help is much appreciated.
You seem to have problem in your Swift code or triggered a bug in the Swift compiler. The symbols your linker complains about are Swift symbols (as identified by the __T prefix). When passed to the swift-demangle tool, the symbols translate to:
_TFC7Bamberg18TourViewControllerm2mmT_ ---> Bamberg.TourViewController.mm.materializeForSet : ()
_TWvdvC7Bamberg18TourViewController2mmT_ ---> direct field offset for Bamberg.TourViewController.mm : ()
So in your TourViewController you seem to reference a field mm, but the linker can't find it. Maybe you can rewrite/reorganize your code to avoid/fix this problem.
After upgrading to Xcode 6 beta 7 (and now still with Xcode 6 GM) I am unable to link my Swift app. I receive errors such as:
Undefined symbols for architecture armv7:
"_swift_stdlib_compareNSStringDeterministicUnicodeCollation", referenced from:
...
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have seen the other SO posts that recommend deleting the Derived Data folder and/or using the Clean Build Folder option to get past this error, but that solution didn't help at all in my case. Nothing has changed about my code or the CocoaPods I'm using since Xcode 6 beta 5 which is the last time it worked.
Any ideas?

What's happening here has nothing to do with your Derived Data location.
When a swift application is built, it goes through several steps:
Write auxiliary files
Create product structure
Compile swift source for each architecture
Copy resource rules plist
Copy application bridging header
Link against swift runtime libraries for each architecture
Copy application swift module for each architecture
Create the application binary
Copy resources build phase
Copy the swift standard libraries into the application
Package it up
Sign it
Whew! That's a lot. Your build is failing when linking against the swift runtime libraries. They live in Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphoneos inside the Xcode developer directory. Specifically, the library that is not being correctly linked is libswiftCore.dylib. If you use nm on that library, you can see it defines your first missing symbol:
quellish% nm /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphoneos/libswiftCore.dylib | grep compareNSStringDeterministicUnicodeCollation
00197c8c T _swift_stdlib_compareNSStringDeterministicUnicodeCollation
000000000018352c T _swift_stdlib_compareNSStringDeterministicUnicodeCollation
You can also use lipo to see what architectures are in the file:
quellish% xcrun lipo -info /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphoneos/libswiftCore.dylib
Architectures in the fat file: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphoneos/libswiftCore.dylib are: armv7 arm64
It contains armv7 and arm64. It's not the library architecture that's the problem.
Linking against the swift standard library is not working. It's possible that source control or migrating Xcode versions has caused your project file to drop part of the linking step, or it's simply not able to find the libraries it needs to link against. Xcode project files are complex and use a lot of references - it's possible that a merge, etc. caused a critical reference to be come dissociated from the linking step. Without a full build log and a look at your machine it may not be possible to tell.
This library, as you might guess, has nothing to do with the project's derived data location.
The best way to move forward would unfortunately be to recreate the project file. Comparing the build log of the broken project to a swift project that does build correctly may provide some insights, but it may also be a waste of time - something fixable may be the problem, but more likely not.
I would encourage you to file a bug and include the troublesome project file with it.
I have solved my issue by deleting all the data in the ~/Library/Developer/Xcode/DerivedData folder. I read about that in another thread, but ignored it thinking a clean included that process!
I have Updated on Yosemite, Xcode 6.1.
I have updated gem xcodeproj (0.19.4) and cocoapods (0.34.4).
I have resolve my conflict by :
Clearing the Library/Developer/Xcode/DerivedData folder
replace in Target -> Build Settings -> Linking -> Other Linker Flags : $(OTHER_LDFLAGS)
Check in Target -> Build Phases -> Copy Pods Resources : "${SRCROOT}/Pods/Target Support Files/Pods/Pods-resources.sh"
1) I face the same problem but just clear the applications from derived data from User/Library/Developer/Xcode/DerivedData and I am able to run the code.
2) In your case may be, it will run by removing armv7 architecture from build settings. And make sure your compiler is Default Compiler in Build Settings.
Thanks I hope this helpful to you and everyone.
This seems to be caused (for most) by linking a third-party library that does not support the requested architecture.
I had somewhat similar problem (a linker error from Apple's framework). As it turned out, the problem was that I was missing the library LocalAuthentication.framework. I am wondering if maybe you need to delete the Foundation.framework from the Build Phase tab (in the Link Libraries section), and then re-add it? Maybe that will solve the problem?
'Upgraded' to xcode 6 and swift app wouldn't build for simulator yet would build fine on an iPad - Linker error, undefined symbols for i386 for the simulator.
Clearing the Library/Developer/Xcode/DerivedData folder worked for me.
There appears to be a bug in Xcode 6.0.1 that is causing the linker to drop dependencies in existing project files. I have had this same problem across several different projects, new and old, since the 6.0.1 update.
The easy 'fix' is to just trash your entire 'Derrived Data' and all build files (i.e. manually clean the project) and then rebuild after a fresh Xcode restart. Magically, the linker now finds all the missing architectures/symbols.
NOTE: I have had several incompatible v-table crashes caused by this same bug. The C++ linker appears to be generating incomplete linkages, causing absurd errors where there are no real errors to be found. Again, just rebuild from a clean state and .. ta da.. save yourself a LOT of headache and wasted time tracking down a non-issue.
I solved this issue after trying all that was suggested here with no luck.
Like someone said earlier, it's a SourceControl issue.
One of my project files (the one referenced in the error message) was missing from the project browser. However, XCode still had a reference to it (I was going to the class definition when I was selecting "jump to definition" from Xcode GUI).
As a matter of fact, the project.pbxproj was not listing it. This was probably a Git Issue. In any event, I just recreated the file in the same directory it has been recreated and voila.
I am a filly when it comes to iOS Objective C, though I have been coding in several other languages for many years. So I am stabbing around in the dark most of the time with Objective C.
I started having this error, "Undefined symbols for architecture armv7", directly after declaring some "global" variables in my .h file like so:
extern NSString *globalNotes;
extern NSString *globalUserCountry;
I was then referring to these variables from the .m file like so:
globalNotes= #"Error (Marker 1010)";
globalUserCountry= #"No result";
THE FIX - To correct this, I changed them to object properties like so:
#property(nonatomic, strong, readwrite) NSString *globalNotes;
#property(nonatomic, strong, readwrite) NSString *globalUserCountry;
And referred to them like so:
self.globalNotes= #"Error (Marker 1010)";
self.globalUserCountry= #"No result";
That seemed to fix my problem.
My project uses some Cocoa static libraries, one of which is a Zxing Project. I am getting a lot of errors while trying to incorporate this project. Weirdly enough, I was able to create a demo with Zxing in a separate project, without any errors. My main project builds and runs ok, as long as I do not include the Cocoa static library for Zxing.
So the question is, how do I include the ZXing static library to my Cocoa project? How do I configure library (e.g. how do I set the Header Search Paths~~).
Thanks.
Some detail about my project

The error
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_QRCodeReader", referenced from:
objc-class-ref in libCustomerLibrary.a(CustomerViewController.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Zxing is kind of a painfull integration, also in the newer versions of Xcode Apple added more error checks. I would suggest you to use cococapods for a better integration or this ObjectiveC wrapper here
It's not seeing some of the lib classes. Double check the steps in the README, particularly step 2. If it still fails, post the link command that fails.
