9 months since this was reported and you still can't use anything newer than 2017.1.2 if you want to use Interpolated rigidbodies on iOS.
There seems to be some conjecture about it actually being fixed in 2018.2 and when that will actually be released.
Most people do not move their projects to the latest release because there is always something else that gets broken.

Anybody can confirm that "Fixed in Unity 2018.2" is real ? 2018.2.0b10 ?

Upon further testing, it is not fixed for a UWP build.
When the framerate is high and constant it works properly, but when the framerate starts dropping or being more inconsistent it does not work properly anymore.
If i compare the interpolation results between unity versions 2017.1.3f1 and 2018.2.0b9 , unity 2017.1 wins by FAR. It works properly even when the framerate is all over the place.
Please fix, this is game breaking.

This is broken on Switch (must be considered a mobile platform) and the problem goes far beyond jittery motion, the physics is completely broken when rigidbodies are set to interpolate. Not everybody can update to 2018, please can we get this fix back ported to 2017 please? We are on 2017.4.4 at the moment. Thank you.

I was wrong about it not being fixed in 2018.2.0b3

I also tested 2018.2.0b3 and the problem still remains in a UWP build running in Hololens.
