My app is crashing with the message:
dyld: Symbol not found: _NSURLAuthenticationMethodClientCertificate
Referenced from: /var/mobile/Applications/C7B596AD-FB09-4685-BDFC-7E955A5DD185/IRON TRAINERS.app/IRON TRAINERS Expected in: /System/Library/Frameworks/CFNetwork.framework/CFNetwork in /var/mobile/Applications/C7B596AD-FB09-4685-BDFC-7E955A5DD185/IRON TRAINERS.app/IRON TRAINERS (lldb)
when I try to build and Run. When I remove the CFNetwork from my project, it works, I don't know why.
I just installed Xcode6Beta and opened my project. It was working fine on Xcode5.1.
UPDATE:
It works fine on iOS simulator with Xcode 6, the problem is on my device running iOS 7.1.1.
UPDATE 2:
The selected answer below worked for me, although I already had foundation framework explicit added to my project, I had to remove it and add it again. Problem solved, at least, for now. :)
Edited to include two possible steps you need to take:
There seems to be a change in which headers include what in iOS8.0 (the glextensions file, for example, is no longer in the top header). If you explicitly add Foundation framework to your project, it will build fine. Making CFNetwork optional will, of course, lead to failures and is only a solution for the build error and not a solution overall.
I had a similar issue with UIAlertAction
dyld: Symbol not found: _OBJC_CLASS_$_UIAlertAction Referenced from: /var/mobile/Applications/ ....app/ ... Expected in: /System/Library/Frameworks/UIKit.framework/UIKit in /var/mobile/Applications/ ....app/ ...
Making UIKit.frameWork
Optional
solved my issue. In your case I am guessing, making your CFNetwork.framework
optional
will solve your problem too.
Re-ordering in XCode didn't do the trick; I'm using Cocoapods, which creates a Pods.xcconfig file. This has a OTHER_LDFLAGS line. I put -framework Foundation
as the first entry, and that's made my project work.
OTHER_LDFLAGS = -framework Foundation -ObjC …
(Beware, this file gets re-generated each time you pod update
.)
Reorder your frameworks to have Foundation before CFNetwork.
That's a temporary fix to something that is obviously a bug in Xcode 6.
