SwiftのFirestoreで前方一致検索をする

Swift

Last updated at 2020-09-26Posted at 2020-09-26

例えばこんなデータがあったとして

let usersRef = Firestore.firestore().collection("Users")
usersRef.document("UserA").setData([
    "name": "UserA",
])
usersRef.document("UserB").setData([
    "name": "UserB",
])

こう書く

let postRef = usersRef.order(by: "name")
    .start(at: [検索したい文字列]).end(at: [検索したい文字列 + "\u{f8ff}"])
