How to practice before moving on?

I will soon finish the beginner Swift course will be moving on to the intermediate course but before I do I would like some direction for practice methods the guided tutorial is great but it allows you to get through with big gaps even if you think you understand/remember the content. Are there any sets of 'tougher' code challenges or something similar that would help me secure my knowledge?

Hey Matthew, how did you end up with this thing ? Did you practice a lot or find out a better solution ? :) Cheers :)

Good question, I'm having the same issue. It's 0 - 100 in 10 seconds building the Vendingmachine. I understand 95% of what Pasan is doing, but there is no way I could have done it myself, even though I passed all code challenges without any problem....
