import <IOKit/IOMessage.h> gives error - ios

I'm using theos on iDevice. Installed it with installtheos3 command. If I got it right, it installed SDK too.
Now I have a project that has
import < IOKit/IOMessage.h >
Also I added IOKit to theos' makefile _FRAMEWORK section. Also I tried to add it to PRIVATE_FRAMEWORKS section.
When I'm trying to 'make' i got this error:
error: IOKit/IOMessage.h: No such file or directory
there is no errors with other frameworks, only with this.
Thank you!

I never use theos, but this kind of error generally come from the Header Search Path option inside Build Settings inside your project settings.

When I ran into similar issue, I had just downloaded files from Github as part of my project and proceed forward.
Problem is, these header files are for C type of library(not really obj C). So I doubt, you would be able to include by changing path or config settings.

For some reasons IOKit framework installed with 'installtheos3' doesn't have Headers directory at all. Copying it solved problem

ld: library not found for -lCocoaAsyncSocket - React Native

I have created a new react native project and when I try to run the app within an iOS emulator it always crashes.
When I open the .xcworkspace within Xcode I get the following error.
I have tried to update the search paths but this has not worked, I have also tried to reinstall pods but this hasn't worked.
This must be fixed on the framework side, however, the solution is the following steps:
On the Xcode bring the Build Settings tab
Find the Search Paths and then try to modify Library search paths
Add ${inherited} to the first of the list. It's important to be the first
Delete the build folder inside the ios folder of the project
Try to run the project again
It must fix the issue
This issue is basically related to the wrongly linking classes. Please follow these steps:
check make sure, you have install all the pods.
Please check your .js files, and check your import statements. To be make sure , every import statement package is installed in your project
clean project
Rebuild again
I can see that you state you have already checked search paths, but I had this same issue, and it was resolved by adding "${PODS_CONFIGURATION_BUILD_DIR}" as recursive to my Library Search Paths, under <Project> > Build Settings > Library Search Paths. However, now I'm stuck on the linker instruction -lcrypto, so it's not a complete solution.

Trouble with an .h import

As a beginner in ObjectiveC I need some help.
I'm working on a phonegap plugin for IOS (so, written with objective C). I use some open source code but I got an error with an .h import.
My architecture look like:
myFmk.framework/
myFmk.framework/ABCDE/myFmk.h <== in a sub folder
myFmk.framework/myFmk <=== this is a file
myPlugin.h
myPlugin.m
In myPlugin.h I have #import and in "myFmk.framework/myFmk" file I have only one line "ABCDE/".
I thought that this file do a redirection of the absolute import (with brackets) but my complier told me that "myFmk/myFmk.h" is not found.
I tried to find some documentation about this feature but I wasn't able to find its name... do you have this documentation or the feature name?
Thks.
Is the framework added using a cocoapod? If not, did you follow the instructions properly for adding it to your project? It would probably help if you posted the framework you are experiencing problems with.
If this is a framework that is added to your project properly and you are unable to import there are a few things you should check. First, go to your project settings (click on the project at the very top of your file tree in the left column) and then look for "linked libraries". See if the library is listed there. If not click the + and try to add it.
If this framework was added via cocoapods another thing to check is search your file structure for libPods.a. If it is red, I find sometimes it is helpful to delete it, close the project and run pod install again.
Also if you installed the project via cocoapods remember to open the workspace and not the old xcode project file.
I have also experienced this problem when my header search paths and other linker flag paths were wrong. Linker Flags should be $inherited if this is a cocoapod. In my projects most Header search paths are $inherited too.
If none of this is helpful please provide more information such as how this framework was added to your project and what the framework is. Also let us know if you get any error messages.

external framework File/File.h (Parse/Parse.h) file not found

So every time I update my app, Xcode claims not to be able to find a particular external framework even though it's there. It's happened again with Xcode 6 and my usual methods (I'm fairly inexperienced, so these basically involve clicking and typing things until something happens (I exaggerate but not by much)) aren't working.
I'm getting a Lexical or Preprocessor Issue error that says 'Parse/Parse.h' file not found.' But here are screenshots of it in the project and added to the library:
I also followed the steps in the most upvoted answer at ‘ld: warning: directory not found for option’ but still nothing.
Any idea what to do? Any idea at all? I'm tearing my hair out here.
Actually I was facing the same problem but after doing lots of (removing/adding parse framework) efforts I come to know that parse.framework is already added and error was still there.
Real Problem was not in link Binary for main project but it was with Tests link Binary.
Lets say your project name is "project1" and Xcode create one more folder with it called "project1Tests". So select "project1Tests" and add parse.framework in link Binary.
Check out the hierarchy:
PROJECT
project1
TARGETS
project1
project1Tests (you need to select this to add parse framework).
Hope this would help you resolve this issue.
I had this error also. I'm developing in Swift, so I added a "bridge header" as described in this Parse blog post.
The reason I got the "Parse.h not found" was that my project name contained spaces. (For project name I mean the Product Name you enter when creating a new project, which determines your folder's name.) The first day all went well, but after closing and opening Xcode, it turns out that Xcode interprets the words separated by spaces as different paths.
To fix this, you can go to Build Settings -> Search Paths -> Framework Search Paths and add an "\" before each space. (If you double click the path you'll see that Xcode shows each word separated by space as a different entry.)
Also note that the bridge header with #import <Parse/Parse.h> it's not compulsory: you can simply do import Parse.
All I had to do was remove Parse.framework from this list by highlighting and pressing delete.
Then I went down to the plus sign at the bottom of that list and had to select Add Other and manually locate the downloaded .framework file.
In my case, the error went away after I added the path to the directory where Parse.framework was to the Frameworks Search Paths Build Setting:
My project didn't even have an entry for that setting, so you may need to create it as well.
I had the same issue when upgrading parse to 1.4v. You have to delete Parse.framework from Framework List and from the project directory, when removed from both places copy again and check "Copy items to destination's group folder". It worked for me.
Its work for me.
Just go to Build Active Architecture Only and Debug should be yes and Release should be No
In my case I had to do one more thing additional to Sukhchais' answer.
It seems that though the parse.framework appears in the 'link Binary with Libraries' list for the targets, they might not have linked properly for some reason. Just remove parse.framework from the list and add it again as mentioned. By that way I was able to resolve my issue.
Just to Share my findings in case if somebody might have the same issue:
Accidentally we had two references of Parse.framework inside our source code base at two different places. And a reference of Parse.framework was linked in Build Phases of the target, from the first place. But when the app is compiled, Xcode was not smart enough to get a reference and trowed an error: "Lexical or Preprocessor Issue" error when "Parse/Parse.h" is imported in .pch file.
After spending couple of hours by trying various options, removed a reference of Parse.framework from the source base and kept only a single reference. This solved the issue.
And the app compiled successfully :)
For people coming from Ionic + Cordova if you are getting this error I solved it by removing my current parsePlugin and replacing it with this fork.
For simplicity, I used these console commands (Replace PARSE_APP_ID and PARSE_CLIENT_KEY with your keys in the Parse Console):
cordova plugin rm com.parse.cordova.core.pushPlugin
cordova plugin add https://github.com/grrrian/phonegap-parse-plugin --variable APP_ID=PARSE_APP_ID --variable CLIENT_KEY=PARSE_CLIENT_KEY
Ok, so I was having this problem as well. I uninstalled all my pods, reinstalled them again, and had no luck.
So the good news (and bad news considering the time I spent trying to find the problem) is that I eventually managed to solve it. Apparently, you have to import Foundation/Foundation.h before parse. I don't know whether this will work for you or not, but I tried everything on the net, and only this seemed to work. If you have any instances of this:
#import <Parse/Parse.h>
#import <Foundation/Foundation.h>
flip it around so that Foundation is declared first:
#import <Foundation/Foundation.h>
#import <Parse/Parse.h>
I also read somewhere that some people had issues with Facebook SDK and Parse SDK import. Apparently, the two have Bolt.Framework in common or something, which causes error. I removed Facebook SDK as well, which at first didn't make any difference. I hope I could help.

Objective C - Precompiled Headers Creating Error

Hi i am importing some classes in .pch file it is working fine. I can build and run too but when those classes that are included in .pch file are accessed complier gives error but still it an build successfully and run the program too. But as soon as i again import them in some class then complier doesn't gives any error. What is the problem that is causing this?
Edit: I tried Cleaning Project and build folder but no effect
I solved this problem by quoting Xcode forcefully and by going to finder->Gotofolder
~/library/developer/xcode/deriveddata
and deleting everything and when i tried running again i was not prompted any error
if you add the three lines under Search Paths->Framework Search Paths as mentioned below
$(inherited)
$(SRCROOT)
"$(SRCROOT)/frameworkname"
I think the problem is Complier not able to locate the framework.
Hope this will help

FMDatabase.h not found when using route-me library

So im trying to use the route-me widget in my app, but xcode keeps complaining that it cant find FMDatabase.h, yet its included in the project (albeit under a different project that is included into my project). I've copied how a sample app has been made yet the sample project doesnt get this error. The RMDBMapSource.h file is contained within the MapView project, so i shouldn't need to include the fmdb stuff myself (and because the sample project doesn't do that)
Surely if the files are under compile sources / copy headers under build phases, that means it should be able to find the file? This is a pretty lackluster explanation of my problem, but if anyone has used the route-me library before maybe they have had the same problem and can point me in the right direction
Resolved my own mistake. First off in the build settings of the main project, the 'search for header paths' was not set correctly, it was set to /MapView/ instead of /MapView/** that resolved the FMDatabase.h missing error.
Then in case someone else had a linker error like i did after i resolved the first issue, make sure you have libMapView.a included in your link binary with libraries section. (i had it their before, but during a version control commit, somehow our project file decided to not add that library anymore and i had totally forgotten about it, so took me quite a while to find out that it was missing)
