Swift compiler segmentation fault when building

Question

Adding a (convenient) computed height property to UIView in my UIViewExtension.swift file is causing the Swift compiler to segfault...

Answer 1

As others wrote above, for me this happened when I'm using an extension over a protocol but the signature of methods in the protocol don't match the implementations in an extension.

In my case, I had added a new parameter to the implementation (in the extension) but forgot to also add it to the method's signature in the protocol.
