Thank you for your example.
This occurs as the Switch uses the checked prop to determine its checked status:
This is described in the last commend here:
As the value props are already used for different information, the Switch defers from the other Form components.
There are two options:
1) inside the custom FormSwitch component, set the value coming from fieldRenderProps to the checked prop:
2) Use the Checkbox component as an alternative to collect boolean values.
I hope this is helpful.
