React Native 0.49 in iOS I clone my project install npm and link from git and run but it has error in RCTBridgeModule.h in code
typedef struct RCTMethodInfo {
const char *const jsName;
const char *const objcName;
const BOOL isSync;
} RCTMethodInfo;
it have 2 Error
Redefinition of 'RCTMethodInfo' and Typedef redefinition with different types ('struct (anonymous struct at ../../react-native/React/Base/RCTBridgeModule.h:57:16)' vs 'struct RCTMethodInfo')
I fine solution and included
#if __has_include(<React/RCTBridgeModule.h>)
#import <React/RCTBridgeModule.h>
else
#import "RCTBridgeModule.h"
#endif
but it error same
I happend to encountered this issue just now.It was caused by a third party
penguin called "react-native-weibo".I just changed #import "RCTBridgeModule" to #import <React/RCTBridgeModule.h> inside RCTWeiboAPI
,then everything is ok now.
so if your issue is caused by third party penguin also,just try to change #import "xxxx.h" to #import <React/xxxx.h> inside third party API.
Hope it works.
I encountered this issue and solved it by deleting Derived Data. The issue was appear cause of up-gradation of project via xcode 10. Previous project's derived data from xcode 9 also present which was unable to delete by cleaning the project for some reason.
You can manually delete the project build files in Derived Data or use command below.
rm -rf ~/Library/Developer/Xcode/DerivedData
Hope it helps!

I am creating Swift framework in which I have to use Objective-C class. So I went through this link. This is the public header of my framework :
#import <UIKit/UIKit.h>
//! Project version number for Test.
FOUNDATION_EXPORT double TestVersionNumber;
//! Project version string for Test.
FOUNDATION_EXPORT const unsigned char TestVersionString[];
// In this header, you should import all the public headers of your framework using statements like #import <Test/PublicHeader.h>
#import <arpa/inet.h>
#import <ifaddrs.h>
#import <netdb.h>
#import <sys/socket.h>
#import <MyTest/MPAppDelegateProxy.h>
Now in class MPAppDelegateProxy, I have to use a Swift class which I have created. This is :
#import "MPAppDelegateProxy.h"
#import "MyTest.h"
#implementation MPAppDelegateProxy
+ (void)proxyAppDelegate {
[MPGlobal MPLog:#"App delegate not set, unable to perform automatic setup." file:#"MPAppDelegateProxy.m" function:#"proxyAppDelegate" line:32];
// rest of code
}
MPGlobal is one of my Swift class. But I am getting :
Use of undeclared identifier 'MPGlobal'
Note : I have added #objC before MPGlobal.
You need to import <Target>-Swift.h file.
This is known as Objective-C Generated Interface Header Name.
You can find it in your Target's build settings.
This file is auto generated by compiler and it needs to be imported in Objective-C files.
change the SWIFT_OBJC_INTERFACE_HEADER_NAME build setting and making it the same across different targets. To do so change the instruction that generates this property from $(SWIFT_MODULE_NAME)-Swift.h to $(PROJECT_NAME)-Swift.h as explained here
After doing this Clean Build Folder by pressing Alt and going into Product menu. Since name of header is shared among targets now it can be imported once in the .m ObjectiveC file and all targets can benefit from Swift classes.
If after building it still shows the error, ensure that the header can be reached from XCode by Cmd clicking on its name. It should open a file that contains code similar to this:
SWIFT_CLASS("_TtC27ProjectName_Summary11MyClass")
#interface MyClass : NSObject
- (nonnull instancetype)init OBJC_DESIGNATED_INITIALIZER;
#end
If need to ensure that those headers are being generated open a terminal and use this command
find ~/Library/Developer/Xcode/DerivedData -name "*Swift.h"
You should see one header for each target
Another issue that happened to me after those changes is that it started giving errors on ObjectiveC code that I didn't touch. The problem was due to the position of the import, as reported here:
Exactly where at the top of a .m file you #import the hidden bridging
header can make a difference. The usual sign of trouble is that you
get an “Unknown type name” compile error, where the unknown type is a
class declared in Objective-C. The solution is to #import the .h file
containing the declaration for the unknown type in your Objective-C
files as well, before you #import the hidden bridging header. Having
to do this can be an annoyance, especially if the Objective-C file in
question has no need to know about this class, but it resolves the
issue and allows compilation to proceed.
At the very end the code compiles and runs on device and simulator!
Original answer
Also you can try this,
You needed to import the -Swift.h for for both the framework and the app target
For Example :
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import <Foundation/Foundation.h>
#import "XLPagerTabStrip-Swift.h"
#import "RealmSwift-Swift.h"
...... // Add all frameworks, subclasses, and dependance ios frameworks
#import "MyProject-Swift.h"
You can read this article How to import file header and check paths
In the AFNetworking's sample code, I use several folders to classify the source codes.
And the Xcode reports:
/Users/.../Framework/AFNetworking.h:19:9: 'AFNetworking/AFURLRequestSerialization.h' file not found
/Users/.../AFNetworking-master/Example/Classes/Networking Extensions/AFAppDotNetAPIClient.h:4:9: While building module 'AFNetworking' imported from /Users/dengjiangzhou/Documents/源码/2_AFNetworking/AFNetworking-master/Example/Classes/Networking Extensions/AFAppDotNetAPIClient.h:4:
/Users/.../AFNetworking-master/Example/:1:9: In file included from :1:
And
Here is the code:
In the AFNetworking.h file
#import <Foundation/Foundation.h>
//! Project version number for AFNetworking.
FOUNDATION_EXPORT double AFNetworkingVersionNumber;
//! Project version string for AFNetworking.
FOUNDATION_EXPORT const unsigned char AFNetworkingVersionString[];
// In this header, you should import all the public headers of your framework using statements like #import <AFNetworking/PublicHeader.h>
#import <Availability.h>
#import <TargetConditionals.h>
#ifndef _AFNETWORKING_
#define _AFNETWORKING_
#import <AFNetworking/AFURLRequestSerialization.h>
#import <AFNetworking/AFURLResponseSerialization.h>
#import <AFNetworking/AFSecurityPolicy.h>
#if !TARGET_OS_WATCH
#import <AFNetworking/AFNetworkReachabilityManager.h>
#endif
#import <AFNetworking/AFURLSessionManager.h>
#import <AFNetworking/AFHTTPSessionManager.h>
Error occurs in the last line.
And I didn't change any code. I just organized the files to check the functions of each module easily.
Maybe insert a file name in the search path of Xcode build settings, is quite OK.
I have not figured it out.
Many Thanks in advance.
You should remove AFNetworking/ from import line and use
#import ""
instead of
#import <>
Go to Build Phases -> Open Headers section -> Move files from Project to Public.
Try this:
Select AFURLRequestSerialization.m
Go to the right tab in the Xcode. Find Target Membership. Uncheck and check again all the boxes.
Product > Clean
Hold Alt and perform: Product > Clean Build Folder...
Build again.
When I build my project with beta 1 it works just fine, but in beta 2 it does not work. In this build I get all sort of errors with libxml I think. For example:
* tree.h:81:3: Unsupported: typedef changes linkage of anonymous type, but linkage was
already computed
* tree.h:346:8: Redefinition of '_xmlElement'
I think this is because somehow libxml is include twice in my project or something. If I change all the #include/imports with the #import xml2 statements it compiles again. The include are guarded by defines.
I want to know if this is the correct solution and why this is needed or is this a bug?
To reproduce problem:
I'm using a wrapper around libxml so I can use objc. When I strip all code the problem can be reproduced with these files/classes:
// DDXMLNode.h
#import <libxml/tree.h>
//#import xml2.tree;
#import Foundation;
#import ObjectiveC.runtime;
#interface DDXMLNode : NSObject<NSCopying>
#end
// DDXMLNode.m
#import "DDXMLNode.h"
#implementation DDXMLNode
#end
I added libxml2 through build phases and just add libxml2.tbd.
As Calimari328 said in the comments this is fixed in xCode beta 3.
I'm using Xcode6 GM to create a Coacoa Touch Framework (a new function in Xcode6), then this framework is included into my app.
Everything is fine (works fine), except that I get warnings in "#import". What is the root cause?
I ran into the same problem and eventually fixed it by adding my project headers into the umbrella header. When you create a new framework it should start with a single .h file titled by the project (in your case DirectProximityFramework.h).
Inside this file is a comment:
In this header, you should import all the public headers of your
framework using statements like #import <DirectProximityFramework/PublicHeader.h>
So just add your GeofencingHelper.h file in this file:
#import <DirectProximityFramework/GeofencingHelper.h>
This should remove all of your warnings!
Maybe, you can stop this warning by adding following line to "DirectProximityFramework.h"
#import <DirectProximityFramework/GeofencingHelper.h>
...etc
I suggest to check
[Target your framework] -> Build Phases -> Headers -> Public
In case if it is not your framework and there is nothing to do you can disable warning in such way
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wincomplete-umbrella"
#import <DirectProximityFramework/GeofencingHelper.h>
#pragma clang diagnostic pop
Note - it is not a fix, it just hide the problem.
I ran into this issue and all the solutions above didn't fit me, since the file wasn't supposed to be in the umbrella header.
So if this is your own framework and that particular file shouldn't be in the umbrella header, make sure it isn't marked public in the target membership section.
That fixed it for me.
I had same issue and my solution was..
When you create the framework project.Your project automatically "yourProjectName.h" file gets created, In this header file import class class.
In my case I am getting missing submodule 'MSFramework.MSLocationManager' [-Wincomplete-umbrella]this warning.
resolved by Just importing
#import <UIKit/UIKit.h>
# import "MSLocationManager.h"
//! Project version number for MSFramework.
FOUNDATION_EXPORT double MSFrameworkVersionNumber;
//! Project version string for MSFramework.
FOUNDATION_EXPORT const unsigned char MSFrameworkVersionString[];
here I just add the # import "MSLocationManager.h"in header file.
// In this header, you should import all the public headers of your framework using statements like
#import <GameworkSDK/GWObject.h>
like this:
#import <UIKit/UIKit.h>
#import <GameworkSDK/GWObject.h>
//! Project version number for GameworkSDK.
FOUNDATION_EXPORT double GameworkSDKVersionNumber;
//! Project version string for GameworkSDK.
FOUNDATION_EXPORT const unsigned char GameworkSDKVersionString[];
i had this problem cocoa pods
my solution was real simple but took forever for me to figure out.
when i ran $ pod install it generated a workspace for me in the same dir as my .xcodeproj file.
however i had already created a workspace to use as its parent directory.
so then i simply deleted my old workspace and went with the one that pods created
glhf!
Set header search path in your project setting:
TARGETS / Build Settings / Header Search Paths
"$PODS_CONFIGURATION_BUILD_DIR/[YOUR PROJ NAME]/[YOUR PROJ NAME].framework/Headers"
Now import the header file.
#import <DirectProximityFramework.h>
I need to download and unzip a file in my Xcode project,
I am using Ziparchive (https://code.google.com/p/ziparchive/downloads/detail?name=ZipArchive.zip) to do so,instead of following every step I am getting compilation error as below:
/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:68:18: Redefinition of 'fopen_file_func' as different kind of symbol

/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:95:1: Expected unqualified-id
I dont have a clue how to compile it successfully, any help is appreciated.
In my case, it happens because I have an incorrect Prefix file.
It was including objective c imports outside the "#ifdef OBJC" block
So that there was no problem when all classes were objetctive-C classes but it didn't compile when I add the C classes of minizip.
Just moving all the imports in the prefix file inside the obj block and voilà!
#ifdef __OBJC__
#import <Availability.h>
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#endif
I hope this helps
Please Add the FrameWork libz.dylib in your project and solve your problem
Project setting -> Target-> Build Phases -> Linked Frameworks and Libraries -> select ibz.dylib
I got the solution,I am using Metaio SDK for Augmented Reality which has a compile dependancy, it can only be compiled as "Compile sources as - > Objective C++" and this was the reason creating the problem, Ziparchive compiled fine otherwise, now to merge both in the same project I made Ziparchive as a STATIC LIBRARY and linked it in Xcode, it solved the problem.
