## Swift (next)

* [SE-0442][]:
TaskGroups can now be created without explicitly specifying their child task's result types:

Previously the child task type would have to be specified explicitly when creating the task group:

```swift
await withTaskGroup(of: Int.self) { group in
group.addTask { 12 }

return await group.next()
}
```

Now the type is inferred based on the first use of the task group within the task group's body:

```swift
await withTaskGroup { group in
group.addTask { 12 }

return await group.next()
}
```


## Swift 6.0

* Swift 6 comes with a new language mode that prevents the risk of data races
