Xcode: ld: library not found for -lAFNetworking

Question

Because of this one reason, build always fails...Any ideas about what I could try?

EDIT: the solution is to open the xcworkspace instead of the xcproject!

Answer 1

Use the xcworkspace to build instead of the xcproject?

This usually happens when using Cocoapods and you are building from the xcproject which doesn't know about the cocoapod libraries.

Answer 2

I have in project->TARGETS->Build Phases ->Link Binary With Libraries one "extra" framework that remains from recent project. Delate it and all run smoothly

Answer 3

I encountered this error when I downloaded some code from github. I tried to build .xcodeproj file but it failed giving the library not found error. I then opened .xcworkspace file and build that file first by clicking Product -> Build for -> Running. The workspace file built fine with no errors. Then in workspace file I changed scheme to the xcode project I was trying to build, and clicked Product -> Run. The app got built and ran with no errors.

I Had this Issue several Times with PODS Libraries.

Here is something you can Try:

1. Run pod cache clean --all and pod install again.

2. Check your Header Search Paths and Library Search Paths, Remove all entries and place $(PROJECT_DIR) in recursive mode and $(inherited) as a Second Entry

3. Go to your target Build Settings -> Other linker flags -> double click . Add $(inherited) to a new line.

Answer 5

Make sure Build Active Architecture Only is set to NO in the Pods project settings.

Answer 6

I had this issue while using fastlane with a ReactNative project. I had added a dependency that required cocoapods.

My Fastfile looked like this:

...
gym(
  scheme: "AppName",
  project: "./ios/AppName.xcodeproj"
)
....

And had to change it to the workspace like this:

...
gym(
  scheme: "AppName",
  workspace: "./ios/AppName.xcworkspace"
)
...
