Alert View - In a switch result - swiftui

Question

I have a button which creates a user when 'Sign Up' / Register is selected.
I have an error message show when there has been an issue with registration and this works successfully. Unfortunately, I want and need to alert the user that the account has been created successfully and to check their email for their verification.
The second alert shows for a split second then disappears, I'm not sure whether this is an issue with it being a second alert in the sequence. Do I need to create an enum, or will this not really matter?
import SwiftUI
import Firebase
struct SignUpView: View {
#EnvironmentObject var userInfo: UserInfo
#State var user: UserViewModel = UserViewModel()
#Environment(\.presentationMode) var presentationMode
#State private var showError = false
#State private var showVerifyEmail = false
#State private var errorString = ""
var body: some View {
NavigationView {
VStack {
Group {
VStack(alignment: .leading) {
TextField("Full Name", text: self.$user.fullname).autocapitalization(.words)
if !user.validNameText.isEmpty {
Text(user.validNameText).font(.caption).foregroundColor(.red)
}
}
VStack(alignment: .leading) {
TextField("Email Address", text: self.$user.email).autocapitalization(.none).keyboardType(.emailAddress)
if !user.validEmailAddressText.isEmpty {
Text(user.validEmailAddressText).font(.caption).foregroundColor(.red)
}
}
VStack(alignment: .leading) {
SecureField("Password", text: self.$user.password)
if !user.validPasswordText.isEmpty {
Text(user.validPasswordText).font(.caption).foregroundColor(.red)
}
}
VStack(alignment: .leading) {
SecureField("Confirm Password", text: self.$user.confirmPassword)
if !user.passwordsMatch(_confirmPW: user.confirmPassword) {
Text(user.validConfirmPasswordText).font(.caption).foregroundColor(.red)
}
}
}.frame(width: 300)
.textFieldStyle(RoundedBorderTextFieldStyle())
VStack(spacing: 20 ) {
Button(action: {
FBAuth.createUser(withEmail: self.user.email,
name: self.user.fullname,
password: self.user.password) { (result) in
switch result {
case .failure(let error):
self.errorString = error.localizedDescription
self.showError = true
case .success( _):
print("Account creation successful")
}
self.showVerifyEmail = true
}
}) {
Text("Register")
.frame(width: 200)
.padding(.vertical, 15)
.background(Color(.systemBlue))
.cornerRadius(8)
.foregroundColor(.white)
.opacity(user.isSignInComplete ? 1 : 0.75)
}
.disabled(!user.isSignInComplete)
Spacer()
}.padding()
}.padding(.top)
.alert(isPresented: $showError) {
Alert(title: Text("Error creating accout"), message: Text(self.errorString), dismissButton: .default(Text("OK")))
}
.alert(isPresented: $showVerifyEmail) {
Alert(title: Text("Email Sent"), message: Text("Verificiation email sent, please also check your spam"), dismissButton: .default(Text("OK")))
}
.navigationBarTitle("Sign Up", displayMode: .inline)
.navigationBarItems(trailing: Button("Dismiss") {
self.presentationMode.wrappedValue.dismiss()
})
}
}
}
struct SignUpView_Previews: PreviewProvider {
static var previews: some View {
SignUpView()
}
}
I'm aware there is a lot of code missing to compile a complete view, but hopefully it can provide enough insight as to why the alert disappears.
Thank you all!

Your code is setting both showError and showVerifyEmail when you get an error. I assume you don't want to do that. So you might try this:
if !self.showError {
self.showVerifyEmail = true
}
