i have a workspace in xcode with two project (sibiling, not parent->child) a project is a static library, and other project is a standard app.
Now i need to drag headers file from library project to app project but this a bit annoying, how i need to configure 'header search path' parameter?
thanks
I add other details: now the path is:
$(SRCROOT)/../Build/Products/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)/include/UtilityLibrary
i create a Build folder and from xcode preferences i configured this folder to receive all builed prioject.

Xcode 12 (Beta) introduced the new multi-platform project template for iOS/macOS apps. If I add a new target (File -> New -> Target... -> Watch App), Xcode adds a new app project to the existing one.
My preference is, that the watchOS-Project uses the shared folder, like the iOS and macOS app.
My question is, how to integrate another app project, like watchOS or tvOS, to an existing multi-platform project? As a reference, I found a GitHub-Project, which integrated watchOS and tvOS in a multi-platform project: https://github.com/jordansinger/SwiftUI-Kit
I also struggled adding an new target for an additional platform. I ended up doing it like this:
Create new project for iOS platform and name it "iOS"
Rename project (first file in the file list) to your product name. Xcode will ask you if you want to rename all other project files -> click on "Don't rename"
While the project file is still selected, you see a column with the targets. Click on the "+" on the bottom and select the app template for an other platform (e.g. tvOS). Set the product name to "tvOS" and click on "Finish".
Add more platforms if needed.
Go through all targets and change the Bundle Identifier for each of them to the correct product name.
Create the following folders by right-clicking on the project file and choosing "New Group": Shared, Shared Tests, Shared UITests.
Now you move the files you want to share between all platforms from one of the platform folders to the "Shared" folder (e.g. ContentView.swift). Delete all those files from the other platforms folders.
Go through all the files in the "Shared" folder and select the other platforms under "Target Membership":
9. Do the same for the Tests und UITests
It's cumbersome, but it works. Maybe somebody else finds a better way...
I want to work with some frameworks like glew and cg so i manually added
the needed frameworks to my project by right clicking the project -> Add files to ...
and choosing the correct framework. The problem is, when i try to include the header files,
Xcode cant find any of them. I hope this picture will help to understand:
And:
The error given is for the glew framework, but it also happens on Cg.
As you can see on the left, The needed frameworks were added.
Any idea on how i can include these headers?
After trying to add the header files manually i got an architecture error:
I dont know if this is how it should look like.
Thanks!
Before starting, remove the framework and all files you have added while trying to make it work.
Then, you have to add the frameworks in the Build Phases of your target. Then go into Link Binary With Libraries and select your framework from there.
This should do it. Your headers should be available as auto-completion after each #import directive.
If it does not work (it sometimes happens), there are additional steps I can provide to you.
Additional steps:
Go to your project settings, in the build settings:
Complete the Framework Search Paths with the path of your framework
Do the same with User Header Search Path
Then, it should work. If it does not, you will need to add the full path of your header in the #import directive. Example:
#import "/path/to/my/header.h"
Apple's documentation available here states:
In the project navigator, select
your project
Select your target
Select the 'Build Phases' tab
Open 'Link Binaries With Libraries'
expander
Click the '+' button
Select your framework
(optional) Drag and drop the added
framework to the 'Frameworks' group
In my case I have added Framework Search Paths for Target, but it should be added to Project
Also Always Search Users Path should be yes
For those whose autocomplete fails after adding framework.
I used to add frameworks, by going to Build Phases and taking the Link Binary with Libraries option. Now in XCode 6.1, though project was building fine, autocomplete in XCode was not working.
So what needs to be done is:
Remove the already added framework from Project Navigator and also from Link Binary with Libraries.
Add framework to project by simply File -> Add Files to option in XCode.
And auto complete will start working.
In my case, the external framework had been downloaded with Windows and added to the project. Then it was transferred to OSX, where the Xcode project was built and the external framework didn't load properly. I guess it is because Windows changes the framework folder to be a regular folder, which OSX then has trouble with.
Solution for me was to simply download the framework with OSX and drag it into the framework folder in the XCode project.
In my case I had to update a framework version, so I just replaced the .framework in the filesystem and then I got the error you've mentioned in the question.
Removing the framework and adding it back again, playing with the search paths and all the other suggestions didn't help.
Eventually, cleaning the build folder did the trick:
Select "Product" from the xcode menu, hold the option key and click on: "Clean Build Folder".
After that I built and ran the project successfully.
So I have one Xcode project that I downloaded that comes with a ~.dylib file and a folder titled 'include' that comes with all the files for that library.
What I want to do is copy these files into another XCode project.
However I don't know how to get XCode to recognize the ~.dylib file. Right now XCode allows me to create instances of classes defined in this library but whenever I try to call any associated methods it says it can't find those methods and gives an error (presumably because the ~.dylib file is not linked properly.
Try this: Select your project file, choose your target, Build Settings, and search for "Library Search Paths", and add the path to your dylib file to it.
Im playing around with the soundcloud api, in its instructions it says to
drag SoundCloudAPI.xcodeproj into your project
add it as a build dependency
I can drag the project in pretty easily, but how does one accomplish the next step?
To add it as a dependency do the following:
Highlight the added project in your file explorer within xcode. In the directory browser window to the right it should show a file with a .a extension. There is a checkbox under the target column (target icon), check it.
Right-Click on your Target (under the targets item in the file explorer) and choose Get Info
On the general tab is a Direct Dependencies section. Hit the plus button
Choose the project and click Add Target
Select your project in the navigator on left.
Open up the drawer in the middle pane and select your target.
Select Build Phases
Target Dependencies is an option at that point.
Tough one for a newbie like me - here is a screenshot that describes it.
Xcode 10.2.1
Under TARGETS in your project, right-click on your project target (should be the same name as your project) and choose GET INFO, then on GENERAL tab you will see DIRECT DEPENDENCIES, simply click the [+] and select SoundCloudAPI.
Just close the Project you want to add , then drag and drop the file .
Xcode add a project as a dependency
Xcode 10
drag-n-drop a project into another project - is called cross-project references[About]
add the added project as a build dependency - is called Explicit dependency[About]
//Xcode 10
Build Phases -> Target Dependencies -> + Add items
//Xcode 11
Build Phases -> Dependencies -> + Add items
In Choose items to add: dialog you will see only targets from your project and the sub-project
Today I faced with the same problem.
As the result of the first run I got next error:
Lexical or Preprocessor Issue: 'SDKProjectName*/*SDKProjectName.h'
file not found.
But before running, I, obviously, added my SDK into the demo project, just drag&drop .xcodeproj file into my test project's source tree. After that, I moved into Build Phases tab in setting of the main xcodeproj file (of the demo) and added my SDK as target dependency and embed framework into corresponding tabs.
But at the result, I got an error above!
So, the problem was into empty line on the Header Search Paths option. I just wrote "../**" as value for this key and project compiled successfully. So, after that, you can add #include <SDKName/SDKName.h> into any project, which includes this SDK.
ps. My test app was created into root SDK folder.
I am an XCode novice. I am trying to follow these instructions. Clearly I am missing something because while I can see that the framework I want has been copied into the app bundle, I can't reference it.
When I start the application from a machine other than mine (or if I remove OpenCV from /Library/Frameworks/ ) I get the following error:
Dyld Error Message: Library not
loaded:
/Users/david/Library/Frameworks/OpenCV.framework/Versions/A/OpenCV
Referenced from:
/Users/g/Demo/Slates/ClipSplitter/build/Release/ClipSplitter.app/Contents/MacOS/ClipSplitter
Reason: image not found
There is no user "david" on my system if that makes any difference. Also this is a prebuilt OpenCV downloaded from the internet. (Here’s a screenshot of the project as requested in comments.)
When the OpenCV.framework has been build it has been configured to use an install path of /Users/david/Library/Frameworks/.
Since you want to use the library as a private framework (installed in the application wrapper at ClipSplitter.app/Contents/Frameworks/OpenCV.framework) you have to change its install path. This can be done easily using the terminal as follows:
$ install_name_tool -id #executable_path/../Frameworks/OpenCV.framework/OpenCV <your_path>/OpenCV.framework/OpenCV
Of course you have to adjust the path of the last argument.
Now, when linking your application, your modified framework tells the linker that dyld has to search for the OpenCV.framework in the app wrapper of your application (in the ClipSplitter.app/Contents/Frameworks directory).
Now you have to copy the OpenCV.framework to your application wrapper. You can do this as part of your build process by adding a copy files build phase: Right-click on your target, select Add->New Build Phase->New Copy Files Build Phase. Select "Frameworks" from the "Destination" pop up and close the dialog.
Your target will now contain a new phase to which you can add the OpenCV.framework by dragging the icon from the Project Navigator on the left side of Xcode window. Note that Xcode won't allow you to add a folder to the Copy Files phase by using the '+' button so in order to copy the framework you'll have to drag&drop it.
You need to set the build setting "Installation directory" to #executable_path/../Frameworks
See the chapter about Embedding a Private Framework in Your Application Bundle in https://developer.apple.com/library/content/documentation/MacOSX/Conceptual/BPFrameworks/Tasks/CreatingFrameworks.html

Using Xcode 5, you can facilitate this using the Build Phases panel of your application target.
The default appearance of this panel is
By pressing the "+" button underneath Copy Files, you can add your framework as a file that will be copied into Frameworks in your app bundle.
Now, when you build, your Framework(s) will be copied into your bundle.
