I feel so wronged. In testing, I set accent color to tint color of iOS system color unfortunatly.
I had to check all files, settings for a day.
App was crashed when system set accent of UI. now that I think about it.
Maybe system try to get tint color for accenting, both color cause infinity loop each other.
Do not set app's accent color to tintColor of system color.
