I've found something that could help. If you are using xcode 7.2 go to Build Phases --> Compile Sources and withe the (-) sign, remove the duplicated item the xcode warns. Then compile and that would solve the issue. Hope this helps you to resolve your issue.

I've successfully added the wikitude plugin into my iOS environment and it runs fine on a device but for some reason, when I attempt to run it in a simulator I get this error:
duplicate symbol _OpenSSLDie in: /Users/adam/iphone/native/Frameworks/sqlcipher.framework/sqlcipher(cryptlib.o) /Users/adam/iphone/native/libWikitudeSDK.a(cryptlib.o)
ld: 33 duplicate symbols for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I'm using the libWikitudeSDK.a and .h/.m classes.
Preceeding that error is this warning, which doesn't appear when building for a device:
ld: warning: tentative definition of '_OPENSSL_ia32cap_P' with size 8 from '/Users/adam/iphone/native/Frameworks/sqlcipher.framework/sqlcipher(cryptlib.o)' is being replaced by real definition of smaller size 4 from '/Users/adam/iphone/native/libWikitudeSDK.a(cryptlib.o)'
