Didn't highlight assert fail line number in Xcode 8

My test code:

~~~objc
...
it(@"should close info dialog", ^{
    [dataModel cancelRequest];

    expect(dataModel.isShowingDialog).to.equal(NO);
});
~~~

when`expect(dataModel.isShowingDialog).to.equal(NO);` fail, Xcode didn't highlight it but have fail log, anything I forgot to set?
