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.
Perhaps a white mulberry? See the Wikipedia: https://en.wikipedia.org/wiki/Morus_alba
