'Property destructuring pattern expected' at transform when trying to type destructuring

[creambyemute]

Hey there,

So I have this in createDrawerNavigator from React-navigation:

drawerIcon: ({ tintColor }) => (
                <VectorIcon
                    iconType="ionicon"
                    iconName="ios-home"
                    iconColor={tintColor || Colors.black}
                    iconSize={24}
                />
)

and wanted to type the tintColor like this: { tintColor } : { tintColor: string }.

Unfortunately when trying to run the bundling fails with

error: bundling failed: Error: C:/Users/tst/dev/react/wap3/src/navigation/drawer/DrawerNavigation.tsx (43,27): Property destructuring pattern expected.

TSLint is set to recommended and react and the TSConfig targets es2018 with "lib": ["dom", "es2015", "es2016"],

Am I being stupid and doing it wrong or is there some problem? Because on ReactJS it worked like this.

Cheers

Turned out it worked after a machine reboot.

Whatever :-)
