I am having trouble with the Estimote Indoor Location SDK in Xcode 7.3.1. The error that I am receiving is as follows:
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
at the end. I have added the EstimoteSDK.framework and the Estimote Indoor Location SDK (two separate items, the latter an extension of the former) to the project in the Supporting Files folder in my Xcode project. I have tried numerous solutions to fix this issue, including:
add double quotes to library search path;
change the Tests host application target;
make sure frameworks are not double compiled;
as well as deleting derived data and cleaning the project often. I am new to Xcode as of yesterday, so the solution may be obvious to you and not to me. It seems that the issue is that the library is not correctly built for the architecture I need? The full error I am receiving is included here.
Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Update: I removed the first error I was receiving, which was appearing because I had double included EstimoteSDK.framework in Link Binary With Libraries.
I ended up solving this issue by removing the framework from the project, redownloading it from GitHub and then adding it to the project again.
