Not young veileds - adult veileds. Usually thery won't eat it until they're mature. There is some debate as to if it's good for them or not. I've fed fruit and vegetables in varying amounts to my veields for years.
In the wild, they eat acacia blossoms, which are often sticky with nectar, and pretty sweet. Even though they do not get access to fruit, they seem to enjoy it in small quantities. I give fruit no more than once every wwek or so. Flowers, like hibiscus, on the other hand, you can give them every day if you want. They're great, especially as a way to kepe them from eating too much protein.
