What species is this? What the fruit?
Looks like it is Phytolacca dioica.  I found this by searching your first image in a phone app called Pl@ntNet (PlantNet).  Looking at Wikipedia confirms the ID.

Interestingly, you said the fruit was sweet.  The North American relative Phytolacca americana is extremely poisonous.  A brief search suggests your species is possibly poisonous, with reports about the leaves more common than the fruit.
