How to fake location on iPhone

It is not possible to spoof your iPhone's Location. If you do not want, for example, friends to see your location in the Find app, you can deactivate location sharing.

You can see how to stop sharing your location here:

Find people and share your location with Find My - Apple Support

Actually, it is possible to do under certain circumstances.

a) you have to be tethered to a Mac (so you can't do it while mobile, unless you take a laptop with you)

b) it requires third-party application such as https://www.tenorshare.com/products/ianygo-change-gps-location-iphone.html (nothing in the base OS allows it)

There is of course nothing that cannot be done under the right conditions hehe.
