Using where with for-loops
Using the where
keyword can be a super nice way to quickly apply a filter in a for
-loop in Swift. You can of course use map
, filter
and forEach
, or guard
, but for simple loops I think this is very expressive and nice.
func archiveMarkedPosts() {
for post in posts where post.isMarked {
archive(post)
}
}
func healAllies() {
for player in players where player.isAllied(to: currentPlayer) {
player.heal()
}
}
