Example code: https://github.com/NiGhTTraX/react-connect-state/blob/132c3a8e8ad880f79078127ce149758d5c324804/src/connect.tsx#L29 that works in 16.8.4. I apologize for not providing a simpler example but I tried reducing it and couldn't reproduce so I'm not sure which part of my code is causing this. I have manually reverted the commit below and my code compiles again.

Error:(29, 15) TS2322: Type 'Readonly<PropsWithChildren<Pick<ViewProps, Exclude<keyof ViewProps, K>>>>' is not assignable to type 'IntrinsicAttributes & Pick<ViewProps, Exclude<keyof ViewProps, K>> & { children?: ReactNode; }'.
  Type 'Readonly<PropsWithChildren<Pick<ViewProps, Exclude<keyof ViewProps, K>>>>' is not assignable to type 'Pick<ViewProps, Exclude<keyof ViewProps, K>>'.
    Type 'PropsWithChildren<Pick<ViewProps, Exclude<keyof ViewProps, K>>>[P]' is not assignable to type 'ViewProps[P]'.
      Type 'PropsWithChildren<Pick<ViewProps, Exclude<keyof ViewProps, K>>>' is not assignable to type 'ViewProps'.

Caused by b5200f6#diff-96b72df8b13a8a590e4f160cbc51f40c. I don't understand why though, maybe the way Readonly distributes over the new type?
