Major Description
From slack:
Hi team, A quick follow up question on whether this is a bug. When customer tried out MutableDocument, it had some unexpected behavior. It has: func contains(key: String) -> Bool. For some reason, MutableDocument's "contains(key
" will return false for a bool key when the bool's value is false. This is despite its "keys" property definitely containing that key. It does not work this way for MutableDictionaryObject. Customer is wondering why? Note: I am not sure if this contains function is supported given that it is not listed in the API reference: https://docs.couchbase.com/mobile/3.0.2/couchbase-lite-swift/Classes/MutableDocument.htmlHere's example XCTest code below that repros issue:
struct ExampleObject: Codable, Equatable {
|
let what: String
|
}
|
|
|
struct ExampleStructure: Codable, Equatable {
|
let hello: String
|
let `time`: Int
|
let `float`: Double |
let `boolean`: Bool |
let otherbool: Bool
|
let null: String? |
let obj: ExampleObject
|
let arr: [Int]
|
}
|
|
|
func testExample() throws { |
let exampleObj = ExampleObject(what: "that") |
var exampleStructure = ExampleStructure(hello: "world", time: 12345, float: 1, boolean: true, otherbool: false, null: nil, obj: exampleObj, arr: [1, 2, 3]) |
|
var jsonData = try JSONEncoder().encode(exampleStructure) |
var json = try XCTUnwrap(String(data: jsonData, encoding: .utf8)) |
var exampleDoc = try MutableDocument(json: json) |
|
print(exampleDoc)
|
XCTAssertTrue(exampleDoc.contains(key: "otherbool")) // Fails |
XCTAssertTrue(exampleDoc.keys.contains("otherbool")) |
XCTAssertTrue(exampleDoc.contains(key: "boolean")) |
XCTAssertTrue(exampleDoc.keys.contains("boolean")) |
|
exampleStructure = ExampleStructure(hello: "world", time: 12345, float: 1, boolean: false, otherbool: true, null: nil, obj: exampleObj, arr: [1, 2, 3]) |
|
jsonData = try JSONEncoder().encode(exampleStructure) |
json = try XCTUnwrap(String(data: jsonData, encoding: .utf8)) |
exampleDoc = try MutableDocument(json: json) |
|
XCTAssertTrue(exampleDoc.contains(key: "otherbool")) |
XCTAssertTrue(exampleDoc.keys.contains("otherbool")) |
XCTAssertTrue(exampleDoc.contains(key: "boolean")) // Fails |
XCTAssertTrue(exampleDoc.keys.contains("boolean")) |
|
|
let exampleDict = try MutableDictionaryObject(json: json) |
|
XCTAssertTrue(exampleDict.contains(key: "otherbool")) |
XCTAssertTrue(exampleDict.keys.contains("otherbool")) |
XCTAssertTrue(exampleDict.contains(key: "boolean")) |
XCTAssertTrue(exampleDict.keys.contains("boolean")) |
}
