Year 11 Student Looking for Courses / Video Playslists to Learn Swift

Hi all,

I'm the IT manager for a small private School and I have an eager Year 11 student who has been trying to learn swift. She has been watching tutorial videos but has come to me asking if I know of any good resources.

Hoping someone on here can point me in the direction of a video playlist, free course, or website that she can utilise to learn how to code for Mac/iOS.

I did look at the 100 days of SwiftUI course but as it's paid it's a no go :/

Thanks so much in advance!
