Pick all that apply

• 1Choice 1.

  Instead of a separate Bool flag per alert, keep one @State private var alert: FormAlert? (enum: emptyName, emptyID, passwordMismatch, success) and present it with the .alert(item:) family, which makes two alerts being on at once structurally impossible

• 2Choice 2.

  The SwiftUI way is to compute the validation for the four fields directly inside body so it runs on every render

• 3Choice 3.

  Don't copy "password mismatch" into a separate @State; keep it as a derived value like private var passwordMismatch: Bool { !pw2.isEmpty && pw != pw2 } and use it for both the live hint and submit validation

• 4Choice 4.

  Passing the @State value as is, like TextField("Name", text: name), works because SwiftUI creates the binding automatically

• 5Choice 5.

  Use .disabled(!isFormValid) on the submit button to block the invalid state up front, but keep the alert validation so submission through another path, like the keyboard's return key, stays safe
