Complete the Code

How can you make sure both load methods run concurrently?

// 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)

Be sure to tweet us with hashtag #CompleteTheCode if you know the answer!

Compiler Error

This week's Compiler Error has a theme: Apple Radar!
1 - The internal Apple Radar app for iOS comes with a sticker pack, allowing Apple engineers to communicate bug statuses in style.
2 - The mascot for Apple Radar is a purple ant eater named Fixie, so inspired because the engineer’s daughter was doing a report on them at the time.
3 - Although the full app was never available to the public, a separate tool called Bug Reporter could be used to file radars, though it was made unavailable in 2019.
4 - It wasn’t until after the iPhone was released that Tim Burks decided to create Open Radar in 2008 to make sharing and duplicating Radars easier for developers.
