Before starting: please check your smith google calendars to see which are being 'synced' to icloud HERE - https://calendar.google.com/calendar/u/0/syncselect

From here you can select or deselect the calendars you wish to view.


Alternatively you can download the Google Calendar App and be able to view all your smith related items there.


Apple's iOS operating system supports connections to Google accounts. To sync your iPhone and Google calendars:

Open Settings.

Select Passwords & Accounts.

In New iOS you will find this option under MAIL > ACCOUNTS

Select Add Account from the bottom of the list.

In the list of officially supported options, select Google.

Three iOS screens showing Passwords & Accounts, Add Account, and Google account choice

Enter your Google Account email address and password. If you've set up two-factor authentication, you will be prompted for your 2 Factor Code

Tap Next. You'll see sliders for Mail, Calendar, Contacts, and Notes. If you only want to sync the calendar, deselect everything except Calendar.

Three iOS screens showing Email or Phone entry, security code entry and Calendars toggle

Tap Save and wait for your calendars to sync with your iPhone. 

Depending on the size of your calendars and the speed of your connection, this process can take several minutes.

Open the Calendar app.

At the bottom of the screen, tap Calendars to display a list of all calendars to which your iPhone has access. It'll include all of your private, shared, and public calendars linked to your Google Account.

Tap the circle right beside the calendar name to change the default color associated with the calendar, then tap Done at the top of the screen.

Select or deselect the individual calendars you want to appear when you're accessing the iOS calendar app.


Limitations

Google Calendar supports several features that do not work on Apple's Calendar app including the room scheduling tool, the creation of new Google calendars, and the transmission of email notifications for events. To use the features, you must access your Google account.

Can You Sync Multiple Google and Apple Calendars?

Got more than one Google account? You can add as many Google accounts as you want to your iPhone. The calendars from each account will be visible in the iOS Calendar app.

Google Calendar and Apple Calendar Bidirectionality

When you sync your Google account with your iPhone, any information you add to it using Apple's Calendar app will flow back to the Google Calendar. Even if you disconnect your Google account from your iPhone, the appointments you created will remain in your Google Calendar. 

Neither Apple nor Google supports the merging of calendars, although merging calendars is possible using some workarounds. Because each calendar is separate and has different security requirements, you cannot see any non-Google calendars loaded on your iPhone from within your Google account.

Alternatives for Syncing Google Calendar to an iPhone

Google offers a version of its calendar app for iOS, and several other developers offer iPhone apps that integrate with Google Calendars.
