I still can build it in Xcode. It also worked fine in AppCode 2016.1.3. However, in 2016.2 it failed with:
"Error:linker command failed with exit code 1 (use -v to see invocation)"
Problem seems to be CocoaPod/My Project Test Target:
My Podfile looks basically like this
platform :ios, '8.0'
target :qeep do
# some more pods ...
target :qeepTests do
pod 'OCMock', '~> 3.2.2'
