Undefined symbols for architecture arm64

Question

I am getting a Apple Mach-O Linker Error everytime I import a file from CocoaPods.

Undefined symbols for architecture arm64:
  \"_OBJC_CLASS_$_FBSession\", r         


        

Answer 1

None of the solutions fix this error in my case(Xcode 9), with TesseractOCRiOS. After hours of trial and error, I came up with a good solution. I just delete 'pod 'TesseractOCRiOS', '~> 4.0.0' in the Podfile, run pod install. And then, add pod 'TesseractOCRiOS', '~> 4.0.0' back to Podfile and run pod install again.

Bang! It works!

Answer 2

I solved it by setting valid archs to armv7 armv7s and setting build active architectures only to YES in release and then doing a new "pod install" from the command line

Answer 3

This worked for me:

ios sdk 9.3

into your build setting of app.xcodeproj valid architecture: armv7 armv7s Build Active architecture : No

Clean and build , worked for me.

Answer 4

I solved this problem by setting that:

ARCHS = armv7 armv7s

VALID_ARCHS = armv6 armv7 armv7s arm64

Answer 5

Setting -ObjC to Other Linker Flags in Build Settings of the target solved the problem.

Answer 6

Had been stuck on this issue the whole day.

I had multiple Schemes, it was compiling fine for Demo, Internal, Release - however Debug scheme just would not compile and was complaining about the libPods.a missing.

The solution was to go to the Project -> Target -> Build Settings and change "Build Active Architecture Only" to YES. Clean and build! Finally hours of head itching solved!
