amazon web services - AWS IOS SDK Error Undefined symbols for architecture x86_64: -


i error after using cocoapods aws sdk ios:

undefined symbols architecture x86_64:   "_objc_class_$_awsinfo", referenced from:       objc-class-ref in libawscognitoidentityprovider.a(awscognitoidentityproviderservice.o)       objc-class-ref in libawsiot.a(awsiotdatamanager.o)       objc-class-ref in libawsiot.a(awsiotdataservice.o)       objc-class-ref in libawsiot.a(awsiotmanager.o)       objc-class-ref in libawsiot.a(awsiotservice.o) ld: symbol(s) not found architecture x86_64 clang: error: linker command failed exit code 1 (use -v see invocation) 

i solved own problem. when created project selected include unit tests project. whatever reason conflicted cocoapod installation. when created new project without unit tests compiled correctly. conflict between 2 or did not configure either way seems units tests , cocoapods need tinkering with.
