Not able to compile Ziparchive library (iOS) - ios

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:68:35: Use of undeclared identifier 'opaque'
/Developer/AR/vuforia-sdk-ios-2-6-8/samples/ARDemo/minizip/ioapi.c:68:58: Expected ';' after top level declarator

/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.

Could not build Objective-C module 'mupdfdk'

I'm trying to add mupdf framework to a swift project. I created a new project and copied the mupdfdk.framework to my project and referenced it in the frameworks section. Following is a screenshot of the documentation.
Now my project looks like this.
Then when I try to import it in viewcontroller, I get Could not build Objective-C module 'mupdfdk' error. Are there any other steps I'm missing? Please help.
You need to add this bridging header:
MuPDF-Bridging-Header.h
#ifndef MuPDF_Bridging_Header_h
#define MuPDF_Bridging_Header_h
#import "mupdfdk.framework/Headers/mupdfdk.h"
#endif /* MuPDF_Bridging_Header_h */
and declare it within the Swift Compiler section of the Build Settings:

Use of undeclared identifier when I want use swift file in objective c project

when I want use swift file in objective c project and I declare an object from swift class, I get "Use of undeclared identifier" error.
the way that I pass:
coping swift file in project and type #objc before declare swift class
create header file in project manually
set "Defines module" in target to Yes
set objective-C bridging header in target to $(SRCROOT)/$(PRODUCT_MODULE_NAME)-Bridging-Header.h
declare #import "productModuleName-Bridging-Header.h" in objective-c file
use name_of_swift_class *s = [[name_of_swift_class alloc] init];
when I want use swift file in step 6 I get "Use of undeclared identifier" error. why?!!! do I have the mistake?
when I test this steps in new project I don't get error but in project that I want it return error.
thank you for your help
The problem is at Step 5 You should not be importing "productModuleName-Bridging-Header.h" instead you should be importing "productModuleName-Swift.h"
P.S- After making this change clean your project, clear your derived data and build it. It will work. Hope it helps :)

Using an Obj-C sub-project in a Swift application

My team has a few full Obj-C libraries we like te reuse in our projects. To do so, we usually set up a git submodule, and then add it to the xcode project as a sub-project (Using target dependency, link binary with library and updating the User Header Search Paths)
So far it's only been done in full Obj-C projects, and I'm now trying to use it in a Swift project but with very little success so far. I tried to add the briding-header file, referenced it in the project and filled it like so :
#import "MyLibraryHeader.h"
With the target header being in the User Header Search Paths.
It lets me build, but when using it in my Swift files:
let test = MyLib();
let secondTest = MyLib.classMethod1("some_arguments");
I get an EXC_BAD_INSTRUCTION on secondTest, and the following logs in the debugger:
(lldb) po test
error: <EXPR>:1:1: error: use of unresolved identifier 'test'
(lldb) po secondTest
error: Error in auto-import:
failed to get module 'MyProject' from AST context:
/Users/siegele/Sources/MyProject_iOS/MyProject/Classes/MyProject-Bridging-Header.h:12:9: error: 'MyLibraryHeader.h' file not found
#import "MyLibraryHeader.h"
^
failed to import bridging header '/Users/siegele/Sources/MyProject_iOS/MyProject/Classes/MyProject-Bridging-Header.h'
Found the following question with no answer : Xcode 6 crashing when using Objective-C subproject inside Swift
Any help would be appreciated.
I followed the HockeyApp tutorial that can be found here:
http://support.hockeyapp.net/kb/client-integration-ios-mac-os-x/integrate-hockeyapp-for-ios-as-a-subproject
In the end, I was on the right tracks but messed up the Header Search Paths:
Add subproject xcodeproj to the workspace
On the main project : Link binary with library, and add the subproject product library (Bonus points : add it as a target dependency too)
Update Header Search Paths (not User Header Search Paths) accordingly
Import your Library.h in the main project Bridging-Header.h file
What threw me off for a while is that the Swift Compiler setting for the Objective-C Bridging Header was not set automatically. Check the Build Settings for your target and ensure the "Objective-C Bridging Header" setting is not blank.

Xcode "Missing Submodule" warning

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>

Private method compilation error

I have imported a library, but during the compilation Xcode shows an error in two .h files of this framework:
#interface BxAbstractDataSet (private)
#interface BxQueueDataCommand (private)
after the first bracket Expected ')'
I thing that there is some problem with the build LLVM settings, but can't solve the issue - any help?
