如何解决错误“模糊使用'增量'"在iOS Firestore上增量() [英] How to fix error "Ambiguous use of 'increment'" on iOS Firestore increment()

问题描述

在尝试使用Swift在iOS中使用Firebase FieldValue.increment(1)时，我收到编译器错误.该错误仅显示歧义使用'increment'"

I receive a compiler error when trying to use firebase FieldValue.increment(1) in iOS using swift. The error only says "Ambiguous use of 'increment'"

我已将所有吊舱更新为所使用的所有Firebase吊舱的当前版本.更具体地说，我使用的是Firebase(5.20.2)和FirebaseFirestore(1.2.1).

I have updated all my pods to the current versions of all firebase pods used. More specifically I am on Firebase(5.20.2) and FirebaseFirestore (1.2.1).

我的代码(如下)与docs

My code (below) is almost exactly the same as the example in the docs Seen at the bottom of this page

如何解决此错误并使应用编译?

How can I fix this error and get the app to compile?

let docRef = db.collection("metadata").document("permanentConversions")
docRef.updateData([
        "total": FieldValue.increment(1)
    ])

推荐答案

如注释中所述，通过将示例中的代码更改为 FieldValue.increment(Int64(1)). 编译器为增量运算符提供了double或int64选项，我想它不知道选择哪个.

As noted in the comments, the "Ambiguous use of 'increment'" error is solved for me by changing the code in the example to FieldValue.increment(Int64(1)). The compiler provides an option of double or int64 for the increment operator and I guess it does not know which one to choose.
