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

I’ve discovered a simple workaround until the problem is fixed in a future Xcode/Swift build:

• Simply place all extensions causing the issue in the .swift file that it’s being used.

In the example project you provided, place the contents of UIViewExtension.swift and CALayerExtension.swift above AppDelegate.swift

Hopefully this can get us to write working Swift code until the problem’s cleared up.
