Library crashes when example is run with release build configuration (Xcode 11.4)

[pepejeria]

I was seeing this issue as well with my app, but have now found an easy way to reproduce:

1. Check that you have the latest Xcode version, which currently is 11.4, earlier versions are fine
2. Download sample project
3. Edit the scheme ProgressRingExample to use the "release" build configuration (see screenshot)
4. Connect an iPhone to your computer and select that device to run the app on

This will result in a crash: GradientGenerator.swift line 113:
let img = ctx.makeImage()!

I have the same issue

The problem is within gradients. When not using gradients e.g.

let useGradient = startColor != endColor

in MKRingProgressLayer then crash does not occur.
so a temporary fix is to disable gradients by using the same start/end color.

Setting the ring to have the same start and end colour fixed the crash for me.

Thanks for the work around. Has anyone found a way to maintain the gradient? It drastically changes the look of my app without the gradient.

If you use this library in your app and want to push a new release: use Xcode 11.3.1

It is not the best approach. I had high hopes for this but struggled with recompiling some external dependencies in older version of Swift :(

Maybe anyone have a fork that is fixed?

Guys, confirm bug on Xcode 11.4 && 11.4.1, the same problem. And that's so disappointing :(

Seems like an option for now.
Anyway look forward to be fixed soon.

Hi guys! The issue was caused by compiler optimizations in Xcode 11.4 - this is now fixed in version 2.2.3 🎉
