How can I transfer videos taken with a Nikon d5600 to my Mac/iPhone?

I just got the camera and realized that the software Snapbridge only works for actual images, not videos. I'm not too familiar with how all of this stuff works but if someone can just explain what to do then awesome. (This video is for a school project so the quicker the response the better.) Thanks again.

Use a card reader to transfer it to your Mac.
You can then transfer the photos to your iPhone.

Always transfer images or videos by removing the card from the camera
and inserting it into a reader (both of my laptops have readers built in).
