Error in Firestore Firebase while running swiftui app

I built a registration page in Swiftui with 8 text fields and connected it successfully with Firestore Firebase. The problem is, I have declared many conditionals for:

  • The user must check the password strength before pressing the "Register Button".
  • If one of the fields is empty, this will occur an error.
  • The password and re-password must be matched.
  • If nothing is wrong, the user should see that he/she successfully registered.

After registering, the fields should be empty.

The button declaration: Button(action: {             alertPresented.toggle()

              //            //Text Fields

//            firstName = ""

//            lastName = ""

//            email = ""

//            password = ""

//            phoneNum = ""

//            studentID = ""

//            coursesNum = ""

//            repassword = ""

//            //After checking the strength

//            passwordStatus = ""

          }) {

            Text("Register")

          }

          .padding(12)

          .frame(width: UIScreen.main.bounds.width - 150)

          .background(Color("Color"))

          .foregroundColor(.white)

          .cornerRadius(8)

          .alert(isPresented: $alertPresented, content: {

            getAlerts()

          })

        }

The getAlerts function:

func getAlerts() -> Alert {

          if self.password != self.repassword {

      return Alert(title: Text("Error!"), message: Text("The passwords NOT matching"), dismissButton: .default(Text("OK!")))     }      

    if (self.firstName == "") && (self.lastName == "") && (self.email == "") && (self.password == "") && (self.repassword == "") && (self.studentID == "") && (self.phoneNum == "") && (self.coursesNum == "") {

      return Alert(title: Text("Error!"), message: Text("Something MISSING!"), dismissButton: .default(Text("Got it!")))

    }

          if self.passwordStatus == "Weak" {

      return Alert(title: Text("Error!"), message: Text("You can't register if the password is WEAK!"), dismissButton: .default(Text("Got it!")))     }

          if trigger == 0 {

      return Alert(title: Text("Error!"), message: Text("Please check the strength first"), dismissButton: .default(Text("Got it!")))

    } else {

      data.addData(firstName: firstName, lastName: lastName, email: email, password: password, phoneNum: phoneNum, studentID: studentID, coursesNum: coursesNum)

      return Alert(title: Text("Congrats!!"), message: Text("You successfully REGISTERED, you can go back to Login"), dismissButton: .default(Text("Awesome!!")))

    }

  }

The problem is when everything is correct and I press the Register button, I got more than 5 documents in Firestore, and the "Something Missing" alert shows, and the fields went empty.
