cannot modify the original post, so repost the question: how to get the value picked by catePickerView from cateName of CatesEnt entity to be saved in fileCate in FilesEnt entity via a TextField? HStack { Text("Folder:") TextField("select", text: $fileData.fileCate) catePickerView(cateName: Array(cates), selectedCate: $selectedCate) // catePickerView works fine by itself }

OOPer, try to get the picked value of Picker that is from attribute of CatesEnt, to show on TextField and save into fileCate attribute of FilesEnt. How can I do that? thanks.
