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

This error happened to me when I tried to override weak variable from parent class.

In base class:

weak var stripeViewDelegate : StripeViewDelegate? = nil    

Derived class:

override weak var stripeViewDelegate : StripeViewDelegate? = nil {
    didSet {
        self.stripeView.delegate = stripeViewDelegate

    }

The error disappeared when I removed =nil from derived class.
