代码在模拟器中运行，在设备上运行时未发现dyld符号错误（Xcode 6 beta）

Question

I'm trying to compile some code that makes use of the CFNetwork framework, and it runs just fine in the simulator (with a deployment target of iOS 7.1), however when I attempt to run it on my iPhone 5 running iOS 7.1, it throws the following error:

dyld: Symbol not found: _NSURLAuthenticationMethodClientCertificate Referenced from: /var/mobile/Applications/...... Expected in: /System/Library/Frameworks/CFNetwork.framework/CFNetwork in /var/mobile/Applications/...

As for information about my app, it is written in Swift, and I am importing CFNetwork through Parse, which I import into my Swift code via an objective-C bridging header.

I am able to resolve this error, as others have suggested, by making the CFNetwork framework optional rather than required. However, the CFNetwork framework is required for my app to work (I'm using Parse as a backend, and it won't communicate without it).

As such, I am curious if anybody else has been able to resolve this issue by utilizing a method other than the above.

Answer 1

I got this error when I was moving an application I made from one computer to another. If you used CMake or something equivalent to generate the project files, then I have a solution: In CMake, instead of selecting XCode as the generator, I switched to Unix Makefiles. Then all I had to do was navigate in terminal to the folder where the make files were generated and type:

$ make
$ sudo make install

This created the application with all of the frameworks and dynamic libraries packaged correctly in my /usr/local/bin folder.

I know that this error is also fixable in XCode, but I spent a lot of time fidgeting with the setting without ever figuring it out. This is my solution for packaging the application; however, I still do all of my editing in XCode.
