[Bug]: JSValueEncoder · Issue #7244 · ionic-team/capacitor · GitHub

麻了, 把报错的EncodingContainer方法替换成

private enum EncodingContainer: JSValueEncodingContainer {case singleValue(SingleValueContainer)case unkeyed(UnkeyedContainer)case keyed(AnyKeyedContainer)var data: JSValue? {switch self {case let .singleValue(container):return container.datacase let .unkeyed(container):return container.datacase let .keyed(container):return container.data}}var type: String {switch self {case .singleValue:return "SingleValueContainer"case .unkeyed:return "UnkeyedContainer"case .keyed:return "KeyedContainer"}}
}
