In iOS 13.1 and Xcode 11 Slider does not work

[materligmann]

I just downloaded iOS 13.1 and build my app with the new Xcode 11. The Slider does not work at all. It is impossible to slide, and the nob does not bounce well, and when I do not do anything, the slider looks like this.

thats weird when i tried in iphone6s and xs Max it worked just fine i'm now trying to solve this issue but i think theres gonna be trade off between smoothness and flatness

[sangriel]

i kindda figured it out. if you see Slider Class of the library theres gonna be a private func redrawFliterview inside this func theres an filter.threshold = 0.49 change this to 0.75 or maybe other value it solves the issue but look little silly when dragging. the blurish thing becomes little bit thinner

Agreed with @sangriel , Just add this line in Slider.swift file:
if #available(iOS 13.0, *) { }
else {
filter.threshold = 0.45
}
you dont need to add 0.75 to filter.threshold.

It will fix the issue.

Tested in iOS 13 and iOS 12

@RaheelCr7 that didn't fix the issue in my current environment (iOS 13.1.3) & Xcode (11.1)

You have to clean the build folder and build this project again so changes can take effects.
