Xcode Linker Error: File not found

Question

I am currently using cocoapods in my Xcode Project to create a google sign in button for my app, and after going through the tutorial steps again, there are still errors showing up on build. Here are the error messages that are showing up on build. Would appreciate any help in fixing this problem.

Short Error Message(At the end of the console error message)

ld: file not found: /Users/tarunaarora/Desktop/GunnOracleApplication/Pods/GoogleUtilities/Libraries/libGTM_NSData+zlib_external.a
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Full Error Message(error message above the short error message):

This is what my Xcode Project Podfile document and Pods show up like:

I am also currently using Xcode 8.2 beta

EDIT:

At the end I have including my solution as to what I did to fix the problem since most of the other ones had not worked. Feel free to look at the solution.

Answer 1

After reading the solutions above, none of them had worked for me, so I started experimenting myself to see if there were any other solutions to this problem.

Here are the steps that had led me to solving this problem:

1. Recreating the Project. (I copied the files I needed and left out the ones I didn't need, so I only copied the Main.storyboard and Assets files)

2. Installing the Pods correctly. (I went through the tutorial I was using again and made sure I was installing the same exact pods he was installing. The project builded without any errors.)

3. Coding the ViewController.swift and Appdelegate files. (I watched the tutorial again, and carefully re-wrote the code that he was writing in the tutorial)

4. Building the project and understanding the errors. (I built the project using the correct scheme settings and then I had went through any errors shown in the console, and corrected them.) All errors that I had encountered, had solutions in the tutorial.

5. Now the project has been successfully created without any errors!

Answer 2

1. In your podfile, notice the difference between ` to '.

2. Once this is corrected, you can:

   a. Clean the project (product -> clean)

   b. Close XCode

   c. Run pod install

   d. Open yourProjectName.xcworkspace

Answer 3

You should change the scheme name. Delete old scheme and add new one!

You can autocreate schemes for your targets by going to Product > Scheme > Manage Schemes and pressing "Autocreate Schemes Now"

Answer 4

Open Build Settings Go to Framework Search Paths

This inherited & Project Directory will cause automatically detection from Pods, and it will not more create problem for you. Try to do so it will automatically detect the pod. Might be this can help
