ld: building for iOS Simulator, but linking against dylib built for MacOSX file

Question

So I'm having a bit of an issue, Apple has rejected my app for the past 3 times. And they've always left me with this error.

so I've been trying to solve this issue with no luck at all, however I just removed all of my Framework Search Path (Xcode sets this one now as default $(DEVELOPER_FRAMEWORKS_DIR))

However when I try to run the app now I'm receiving this error

ld: building for iOS Simulator, but linking against dylib built for MacOSX file '/Applications/Xcode51-DP2.app/Contents/Developer/Library/Frameworks/SenTestingKit.framework/SenTestingKit' for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

run this command on your client.app:

export PATH=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xct‌oolchain/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:$PATH

in terms of the name of your Xcode is Xocde.app.
