I've started iOS development this week and have run into an issue importing a third party SDK which is in the form of a static library.
This seems like it should be pretty straight forward but I can't seem to get Xcode to recognize the library.
The SDK ( due to an NDA I can't name the source) is in the form of two .a files, one of which is about 10kb and the other that is a little over 10MB. There is also an "includes" directory that has header files.
What I have done is highlight my project in the project explorer on the left, hit the "Build Phases" tab and under "Link Binary With Libraries" I add the .a file. Under build settings I go to "Search Paths" and I add the path to the includes directory under "User Header Search Paths".
Now in my project explorer I see the library I added under "Frameworks" as filename.a - however the icon is different than the other frameworks I have in that it looks like a blank document(don't know if that is relevant) and there is no arrow icon next to it that allows the framework to be expanded.
When I do an import of one of the header files e.g
#import "theAPI.h"
I get a header not found error. I know that this is one of the header files that are in the includes directory.
The steps I followed were in the XCode docs, I'm not sure what I am missing. If anyone had any suggestions on what could be going wrong here I would really appreciate it. Thanks!
Sounds like the problem is that xcode can't find your header files.
Double check your header search path.. if xcode can find it then it should auto-complete your #import statement for you.
You can also try to add the include directory into the library search path then you should be able to include headers like this:
#import <theAPI.h>

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.
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.
This just started happening with my project and I have no idea what to do.
I've been using the Parse framework and everything has been fine so far. But now, even though the library is included:
and linked:
I still get a "'Parse/Parse.h' file not found" error when I import it into classes. Even weirder (at least to me), the project still builds and runs. When I build or clean the project, the warning disappears, but then it reappears right away.
Any idea how I can fix this?
For all who have not found issue:
Go to Build settings and search for "Framework Search Paths", then remove everything and put ./ and make it recursive (by double-clicking on it)
IMPORTANT - Don't download Parse framework on Windows and then copy to Mac! inside framework there are some links and while copying they get corrupted. Download the framework directly from Mac and when added to xcode make sure it has "Headers" folder under it in XCode frameworks.
I hope it helps some people.
have you tried by changing the #import "Parse/Parse.h" to #import ?
The compiler will search for the header files in a special search path. In your case, it seems that the file "Parse/Parse.h" is not in your compiler's header file search path. Check this in your compiler settings.
How many targets do you have? If more than one, maybe the debug target doesn't include the framework.
I have the same problem when I use the demo called "TodoTable", and I solve this by deleting the link in target -> Build Phases -> Link Binary With Libraries -> Parse.framework, and then, adding it again. You may do it by clicking + button, and choosing Add other..., then, in the project folder, you can find the Parse.framework file. After that, rebuilding your project, and it will be ok.
I downloaded MapBox example from github using the following
git clone --recursive https://github.com/mapbox/mapbox-ios-example.git
Which downloaded it including all dependencies. Now I'm trying to create a separate project and include MapBox DSK as it was in that example. I tried creating workspace then creating a single view project then add new file and select .xcodepro for the MapBox DSK but didn't work when I tried importing MapBox.h file. I never tried importing 3rd parties API before and a bit not sure how I can do that correctly. Any Idea how I can accomplish that ?
Thanks in Advance
Just try:
#import <Mapbox/Mapbox.h>
instead of just importing Mapbox.h as suggested here:
https://www.mapbox.com/blog/ios-sdk-framework
You simply drag the Mapbox-ios-sdk project file from Finder to the files pane in Xcode.
And then click the project in Xcode files pane, Target-->Build Settings. Search for "User Header Search Paths". Specify where the MapBox sdk is located.
What I do is I put the MapBox-iOS-sdk in my project directory. And I set the path as $(SRCROOT) and make sure to set it as recursive.
While you're at it also make sure -ObjC and -all_load are set in Other linker flags.
That only helps you reference the .h files, to link, also under Build Setting, Link Binary with Libraries you need libMapBox.a.
If there is a MapBox.bundle (as in the latest development branch) in the group and files pane, you want to drag that into Target->Build phases->Copy bundle resources as well. (The add button doesn't work for me.)
I think the best way is to look at mapbox-ios-example provided by MapBox and try to replicate all dependencies into your own project.
A bit late but I did it like it was explained here: http://mapbox.com/mapbox-ios-sdk/#binary.
Not messing around with git, just dragging things into your project, easy!
I think problem here is he couldn't find a specific 'file' that was titled "MapBox.Framework" inside the folder of resources downloaded from Map Box, however what you actually need to do is copy that whole folder, which is titled "MapBox.Framework" into the frameworks section. I think the confusion was that the main folder that needs to be copied doesn't look like the yellow framework icon until you copy that folder into Xcode's frameworks section.
