Swift: Sign in a user through OTP

• This method is used for passwordless sign-ins where a OTP is sent to the user's email or phone number.
• If the user doesn't exist, signInWithOTP() will signup the user instead. To restrict this behavior, you can set shouldCreateUser to false.
• If you're using an email, you can configure whether you want the user to receive a magiclink or a OTP.
• If you're using phone, you can configure whether you want the user to receive a OTP.
• The magic link's destination URL is determined by the SITE_URL.
• See redirect URLs and wildcards to add additional redirect URLs to your project.
• Magic links and OTPs share the same implementation. To send users a one-time code instead of a magic link, modify the magic link email template to include \{\{ .Token \}\} instead of \{\{ .ConfirmationURL \}\}.
• When using magic links, specify a redirectTo that matches a configured url scheme in your iOS app, so Supabase can correctly redirect back to your app.
• See our Twilio Phone Auth Guide for details about configuring WhatsApp sign in.
