iOS Question [closed] mails-and-sms-messages error

[anOparator]

While https://www.b4x.com/android/forum/threads/mails-and-sms-messages.46131/#content compiles to the Simulator on the included video, for me the BarButtons only appear when I comment these lines:

'mailButton.Enabled = mailc.CanSendMail
'smsButton.Enabled = smsc.CanSendText

Then clicking 'SendMail' has error on line 54:

 mailc.SetToRecipients(Array("hello@example.com", "world@example.com"))

I have compiled several other pages ok.
What might have changed since the tutorial was made?
Am using Build server 5.02, Xcode v9.4.1, High Sierra

You must keep these two lines. If the buttons are disabled then it means that the features are not supported by the current device.

Ok, I'm thinking it's a no Sim card issue.
What steps do I need to take to compile and test my email project on a simulator as shown in the tutorial.
Am trying not to get an Apple developer account until a lot of testing has been done.
Thanks in advance.

All the code you need is included in the example. You cannot test SMS features on the simulator.
