You can do it manually. In your model class, override awakeFromInsert and set your strings to empty string

Swift:

override func awakeFromInsert()
{
    super.awakeFromInsert()
    self.stringProperty = ""
}

Objective-C

- (void) awakeFromInsert
{
    [super awakeFromInsert];
    self.stringProperty = @"";
}
