got following error with this code:

Code:

lazyvar documentDir = URL {
        let allUrls = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
        return allUrls[0]
    }()

Fehler:

Unable to infer complex closure return type; add explicit type to disambiguate

Insert ' () -> URL in ' FIX

When I'm clicking on Fix another error occurs:

Cannot invoke initializer for type 'URL' with an argument list of type '(() -> URL)'

How to solve this Problem? I'm using a CoreData Project

I guess you may want to do something like this:

    lazy var documentDir: URL = {
        let allUrls = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
        return allUrls[0]
    }()

`URL {...}()` does not make sense as an expression.
