Issue Description:
What
A crash happens in the package code when used as a Swift Package Manager dependency.
This only happens only in Xcode 11.2 beta 1 & beta 2. The same code / project works well in Xcode 11.0 and Xcode 11.1. So I believe it is a regression of either Swift compiler or Swift Package Manager (or build system).
It says EXC_BAD_INSTRUCTION but there is no other clue. I have no idea on the reason.
How
Sample repo:
https://github.com/onevcat/Kingfisher-Crash
It is a SwiftUI project, with Kingfisher imported by Swift Package Manager. The ContentView just uses KFImage to load an image from Internet.
Expected
The image loaded and a cat image shown in the middle of the screen.
Actual
The app crashes inside some initializer code in Kingfisher.

Notes
The same project and integration way works fine on Xcode 11.0 and Xcode 11.1.
With Xcode 11.2 beta / beta 2, the app crashes not only on iOS 13.2 beta, but also crashes on iOS 13.1. So I guess it is more likely a compiler or build system issue?
