Cocoa Pods failed to link libraries while running in the debug mode?
cocoapods, ios, objective-c, xcode
Solution
if the above answer didn't work for you, maybe the problem comes from when you installed the pods. Check if you had such message when running `pod install`
The ProjectName [Release] target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/ProjectName/Pods-ProjectName.release.xcconfig'. This can lead to problems with the CocoaPods installation
or a similar message but with `debug` instead of release (or both). If so, delete the pod project in your workspace in Xcode, then follow the answer to this question The target ... overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Pods.xcconfig, I past it here :
This definitely works most of the time:
Go to your target Build Settings -> Other linker flags -> double click . Add $(inherited) to a new line.
And then run `pod install` again. It did it for me.
Problem
I m using `pods` to link libraries like `AfNetworking`, `facebook` etc. and its working great in `release` mode but I want to check Variables value by debugging but it shows all the variables nil in release mode. I tried to run in `debug` mode by editing schema but it failed to compile showing various libraries not found error. Edit I have tried updating the architectures.....but this isn't helping out. Error log in debug mode ``` ld: warning: directory not found for option '-L/Users/madept/Desktop/personally/Pods/build/Debug-iphoneos' ld: warning: ignoring file /Users/madept/Desktop/personally/libCloudinary.a, missing required architecture x86_64 in file /Users/madept/Desktop/personally/libCloudinary.a (3 slices) Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_AFHTTPRequestOperation", referenced from: objc-class-ref in ZRAPIClient.o "_OBJC_CLASS_$_AFHTTPRequestSerializer", referenced from: objc-class-ref in ZRAPIClient.o "_OBJC_CLASS_$_AFJSONResponseSerializer", referenced from: objc-class-ref in ZRAPIClient.o "_OBJC_CLASS_$_BITHockeyManager", referenced from: objc-class-ref in ZRAppDelegate.o "_OBJC_CLASS_$_CLCloudinary", referenced from: objc-class-ref in ZRMediaManager.o "_OBJC_CLASS_$_CLTransformation", referenced from: objc-class-ref in ZRMediaManager.o "_OBJC_CLASS_$_DDFileLogger", referenced from: objc-class-ref in Zooplr.o "_OBJC_CLASS_$_DDLog", referenced from: objc-class-ref in Chat.o objc-class-ref in ZRManagedObject.o objc-class-ref in ZRTelescopingScrollView.o objc-class-ref in ZRAddMessageBarController.o objc-class-ref in ZRCreateAccountViewController.o objc-class-ref in ZRAddressBookHelper.o objc-class-ref in Zooplr.o ...
