Answer 1

one more case that can lead to this error which just took me hours to track down: a failable initializer that always returns nil.

i had an initializer that looked like this:

init?(object: MyObject) {
    if object.importantProperty {
        // initialize
    }
    return nil
}

when what i meant was:

init?(object: MyObject) {
    if object.importantProperty {
        // initialize
    }
    else {
        return nil
    }
}

fixing the initializer made the error go away.
