Linker Command failed with exit code 1 (use -v to see invocation), Xcode 8, Swift 3

i was facing same issue today in xcode 8 version 8.3.2

right click on issue --> reveal in log

then you are able to check what is causing that issue

Maybe you installed a pod file and you are still trying to build from the .xcodeproj file instead of .xcworkspace

the only thing that worked for me was to run pod deintegrate and pod install
