Apple Mach-O-Linker Error CocoaPods

Question

I've been trying to get my app up and running. From what I could tell the app was missing Cocoapods as a dependency. So. I installed and added Cocoapods. But I'm still getting the same error for whatever reason. I'm an inexperienced developer trying to teach himself I must add.

ld: library not found for -lPods
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Solution 1

This error usually occurs either when you don't have the correct frameworks (might be missing one) or when you don't have the right thing in linker flags.

Go to the main page for the app (on the navigation thing on the left click on your apps name or the top section) -> Build Settings and under Linker Flags, make sure there is nothing in your Other Linker Flags. I had this same error when I had -ObjC in my other Linker Flags.

You might also want to try adding -lPods to your Other Linker Flags or adding the CoreGraphics framework if you don't already have it.

Good luck

Solution 2

Open workspace file, not project file. Cocoapods automatically creates a xcworkspace file on the same directory as xcproject file.

Solution 3

Xcode started displaying this message and I tried pretty much everything to solve it. What finally did the trick for me was deleting all content from ~/Library/Developer/Xcode/DerivedData/

Yeah that's how I open it.

Maybe project file is manually edited and broken. Can you try using pod update command again, so it can fix this kind of reference problems?

[fabian]

Are my linker flags okay (check the new image at the top of my post)

[fith]

Same! Thank you! So many unsolved tickets with this problem; glad I finally found this one.

[Davide Callegari]

I believe that @dadalar answer is more correct than this one, it worked for me.

Thanks! I deleted $(inherited) from my Other Linker Flags and it worked. Wish I had found this while I still had my hair.
