TS2538: Type 'unique symbol' cannot be used as an index type
I have this:
const symbols = {
typeMap: Symbol('type.map')
}
interface LangMap {
[key: string]: string | true,
golang: string,
typescript: string,
java: string,
swift: string
}
export const setTypeMap = function(v: LangMap) : LangMap{
v[symbols.typeMap] = true;
return v;
};
I get this error:
TS2538: Type 'unique symbol' cannot be used as an index type.
Does anyone know what that error is about? I am on tsc version 3.1.6.
tsc typescript3.0

Unfortunately this issue appears to still be outstanding (I was actually led here by your comment on GitHub). I've just pinged some TS maintainers to see if there's anything that can be done.
