Complete the Code
How can you make sure both load methods run concurrently?
```swift
// How can you make sure both load methods run concurrently?
func loadItem(_ id: UUID) async {
let image = await loadImage(id)
let metadata = await loadMetadata(id)
presentItem(id, image: image, metadata: metadata)
}
```

Compiler Error
This week's Compiler Error has a theme: Cryptocurrencies!
1 - One of the first cryptocurrencies, Litecoin was created in 2011 based on Scrypt out of concern that GPU-based mining was too high a barrier to entry.
2 - Zcash, founded by Zooko Wilcox, is the first open, permission less financial system employing zero-knowledge security, and employed a “ceremony” to generate the system’s private key.
3 - Titcoin was created in 2014 as the first cryptocurrency to be nominated for a major adult industry award, and featured greatly improved transaction speeds over Bitcoin.
4 - iCANhaz was an ill-fated cryptocurrency founded by Burger King in 2018 that could be earned by purchasing cheeseburgers, though most ended up lost since wallets containing the coin were printed on wrappers themselves.
