Expression type 'ContraintGroup' is ambigious without more context ?

[huangxueqin]

why xcode report error: Expression type 'ContraintGroup' is ambigious without more context ? when using constrain function? actually cartography is totally unusable in my project

Would you mind providing more… context?

It's difficult to help if we don't know the expression.

Also, about constraingroup, it has memory leak that I can't clear it as I mention on https://github.com/robb/Cartography/issues/248
