I am having trouble with Xcode referencing header files from imported frameworks. The strange thing is that everything worked fine yesterday. But now, I cannot even import the same headers I see one line above that do not give me a compiler error.
You can see in the image below that the compiler is fine with "Ironsource/Ironsource.h" but when I'm trying to add it again it doesn't know what it is (but it did yesterday):
It is not a localized problem to one Xcode project, Xcode cannot see header files in any of my projects. Or more precisely, Xcode cannot see any NEW header files I would like to import but has no problem with the ones imported a day before. So, I am guessing it is something with Xcode, but I cannot figure out what went wrong.
Also, it doesn't matter if I try to reference headers in:
.framework
.xcframework
files.
The frameworks were added manually in the Project Navigator and can be seen properly in Target -> Build Phases -> Link Binary with Libraries.
I am using Xcode 13.3.1. and my project and used frameworks are both pure Objective C. I have both restarted Xcode and my Mac multiple times but they didn't help.
Does anyone have an idea what went wrong?
Framework headers are usually imported with angular brackets "<>". If you use quotes the compiler would search in the User header search paths in which case you would need to add the relevant path to User header search paths. Also make sure to make the header public if you use angled brackets.

I downloaded this Xcode project and I want to use my Swift files in the Objective-C files but the 'OpenShop-Swift.h' file not found error refuses to go away.
I have tried what seems like every solution on Stack Overflow, including from here and here. Most other solutions were duplicates of the common:
In build settings, set defines module to yes and product module name for the target to your project name and make sure objective-c generated interface header name is correct.
This top solution seemed promising but I am having trouble understanding what he was saying.
If you decide to give it a whirl, just know that the project lacks a working backend and won't compile properly if you get past the file not found error. But, if you add to one of the .m files you should be able to get the error before the project finishes compiling.
Technically, this is not a duplicate since all the other solutions have failed.
I have found the solution thanks to #skladek. I created a swift file and allowed Xcode to create a bridging header file for me when it asked, and the error went away.
I thought the bridging header file (OpenShop-Bridging-Header.h) was to allow the importation of Obj-C code to Swift files and not vice-versa. Thus far everything I have read on the internet has corroborated this, so it's not clear to me why this solution works. Thanks to #skladek once again.
So I am trying to add a static library to my project in order to interface with a scanner. I have linked the binary in build phases to the libCaptuvoSDK.a, put the Captuvo.h header file in the project folder, and finally set the project to always search the user paths and added $(BUILT_PRODUCTS_DIR) recursive to the user header search paths. After doing all this I am trying to use #import "Captuvo.h" in my ViewController.swift file and getting the 2 errors Expected identifier in import declaration, and Expected expression. I have tried different combinations of importing and none of them seem to make a difference so I am led to believe the issue is with my process of adding the library.
I am new to Xcode and have never used a third party library in an application before so I feel I may be making a simple mistake or just misinterpreting things. Any help is appreciated!
Okay so I managed to fix my issue! I had imported the static library properly but the real issue was the header file. I fixed my issue by creating a new file in my projects folder named Quick-Scan-Bridging-Header.h. Inside that file is where the #import "Captuvo.h" line belonged. Once that was done I opened the Quick Scan apps build settings and under Objective-C Bridging Header I added the path Quick Scan/Quick-Scan-Bridging-Header. I also added the Header Search Path $(BUILT_PRODUCTS_DIR)
After I did all this I am able to use the Captuvo classes in my ViewController.swift file.
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.
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)
I am trying to import the NYXImagesKit library in to my iOS 5.1 project but it will not show up as importable code. It cannot find the library. I have dragged the NYXImagesKit library in to the project and added the libraries. I have also added the following to my build phases:
However I still get an error saying it cannot find NYXImagesKit.h when i try to import it.
NYXImagesKit can be found from here: https://github.com/Nyx0uf/NYXImagesKit
Ive used this in a previous project so I know that it works.

You are not having an issue with "importing" the library proper. (I would not like to appear pedantic, but a library is linked, not imported). The issue you are having is with the header file which comes with the library.
To fix it, you should make sure to add the path to NYXImagesKit.h in your project build sentting (Search Headers Path). This can by found under Build options in your project settings.
Alternatively, an easier way is to add the NYXImagesKit.h file to your project (like any .m file). Then it will be found without the need to specify an header search path.
EDIT:
Since from what you report, everything seems ok, he only idea I can come up with is making sure that the paths are defined for your target (as opposed to the project overall); but I guess it is already like that.
Other than that, only resort is thinking that the project got corrupted somehow. You can inspect the project.pbxproj file inside your .xcodeproj document with a text editor and ensure that everything looks fine.
If everything fails, just start over with a new project.
