Xcode Linker error: File not found

I am currently using pods to create a google sign in button in my app, and now I have a linker error on build. Appreciate any help in fixing this problem.

Short 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)

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

Podfile and Pods image

I am also currently using Xcode 8.2 beta

Answer

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!
