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:
B4X:
'mailButton.Enabled = mailc.CanSendMail
'smsButton.Enabled = smsc.CanSendText
Then clicking 'SendMail' has error on line 54:
B4X:
 mailc.SetToRecipients(Array("[email protected]", "[email protected]"))
B4X:
 Application_Start
Application_Active
Error occurred on line: 54 (Main)

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

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.
