Final answer:

Step-by-step explanation:
How to Clear Cache on Safari for iPhone
To clear cache on Safari for your iPhone, follow these steps:
Go to the Settings app on your iPhone.
Scroll down and select Safari.
Scroll down again and click on Clear History and Website Data.
Confirm by tapping Clear History and Data again when prompted.
Doing this will clear all history, cookies, and browsing data from Safari. If you only want to clear the cache without deleting history or cookies, you will need to remove website data individually:
In the Safari settings, tap Advanced, then Website Data.
You can then edit and remove data from specific sites or remove all website data.
It's important to note that clearing your cache will log you out of any websites you were signed into and can change how websites behave until they save new data to your phone.
