Hi,
i'm trying to using your library in my project.
I've tried via cocoa and via manual import but every time i try to build and launch on my iPhone i get this error:

ld: warning: directory not found for option '-F/Users/Me/Documents/MyApp/Charts/ThirdParty/Realm/ios'
ld: warning: ignoring file /Users/Me/Library/Developer/Xcode/DerivedData/myproject-dbdiljwlqdyklosctawpbofhrmqd/Build/Products/Debug-iphoneos/Charts.framework/Charts, file was built for arm64 which is not the architecture being linked (armv7): /Users/Me/Library/Developer/Xcode/DerivedData/myproject-dbdiljwlqdyklosctawpbofhrmqd/Build/Products/Debug-iphoneos/Charts.framework/Charts

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've tried already to clean many times without any different result.
Can you help me?

Solved importing manually in project and Change "Build Active Architecture Only" to "NO" and adding supported architectures
