Hi @dolivervl . The showOIosInstall in fact doen nothing but displaying an HTML block with some instructions. This is because at the time the article was written (haven't checked if this has changed) IOS had no support for PWAs. But IOS does support installing a website as if it were an application.
Please refer to the article in Medium for further information.
Best regards.
