I am trying to integrate Google Sign In into my iOS Apps but while doing this i am getting below error.
Is there any solution to remove below errors?

You can fallow below steps
Go to Build settings / Linking / Other Linker Flags and add the "-ObjC" without the quotes. This assume you are using some "header
file" to map Google framework and for Swift approach.
Go to Build Phases >Link Binary with Librairies > + > Add other, the go to de /usr/lib directory and select "libz.dylib"
Compile

This is very common error and doesn't have any specific solution. Although may be following workaround may help you:
If you are not using
cocoa-podsuse them to add new repos.Check that you haven't imported
.minstead of.h.Check you haven't add two frameworks accidenlty.
Remove
-ObjCLinker flag from `-otherLinkerFlags'Sometimes using older version of sdk may solve the problem.
Navigate to
YourProject--Build Phasesand check you haven't added one file more than once. And also anyLink Binary and Librariesare not missing from there.
Here is the Image Showing OtherLinkerFlags

Adding -ObjC and libz solved my problem. However in my case I can't find libz.dylib in path /usr/bin. I used libz.tbd in the iOS 9.3 folder instead and it also worked fine and dismissed those same errors.
