Undefined symbols for architecture arm64: “_OBJC_CLASS_$_GSDK_GTMLogger”

For the first time I try to build and run my app for ios, it’s already working fine for android. Unfortunately I’m getting the following error that drives me crazy. I did everything multiple times as described on the ionic website.

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_GSDK_GTMLogger", referenced from:
      objc-class-ref in GoogleIPhoneUtilities(GIPReachability.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Build Settings -> Other Linker Flags are set to: $(inherited)

I am grateful for any idea or feedback.

Did u solved this issue?
