UIExplrer's test targets were being built on normal builds as well, remove it.
Test Plan: Insert an `#error` on a test file, and run the project. It shouldn't fail anymore.
Summary:
@public
I've increased the warning levels in the OSS frameworks, which caught a bunch of minor issues. I also fixed some new errors in Xcode 7 relating to designated initializers and TLS security.
Test Plan:
* Test the sample apps and make sure they still work.
* Run tests.
