Include Headers from added frameworks on Xcode

Question

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 ->

Answer 1

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.

Answer 2

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

Answer 3

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:

1. Remove the already added framework from Project Navigator and also from Link Binary with Libraries.
2. Add framework to project by simply File -> Add Files to option in XCode.

And auto complete will start working.

Answer 4

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:

1. In the project navigator, select your project
2. Select your target
3. Select the 'Build Phases' tab
4. Open 'Link Binaries With Libraries' expander
5. Click the '+' button
6. Select your framework
7. (optional) Drag and drop the added framework to the 'Frameworks' group

Answer 5

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.
