@xedin, is this familiar? |
|
Unfortunately `count(where: )` has been reverted. @moiseev are there any alternatives in stdlib? |
|
`xs.count(where: predicate)` should be equivalent to `xs.lazy.filter(predicate).count` when `xs` is a `Collection`. |
|
Xcode 10.2 beta 4 change-log mentions that `count` has been removed and provides an alternative way to perform the same job. https://developer.apple.com/documentation/xcode_release_notes/xcode_10_2\_beta_4\_release_notes/swift_5\_release_notes_for_xcode_10_2\_beta_4?preferredLanguage=occ |
