I'm using SwiftData, and I'm using iCloud's CloudKit feature to back up my data. The problem here is that once you start backing up your data, you can't erase it completely. Even if the user adds 4 data and erases 4 again, I'm using about 2.5kb. I don't know how the user using the app will accept this. I'm trying to provide the user with the ability to erase data at once, what should I do??

Can i use c++ library with c library in swift app project Hello. I want to use a C++ library in my Swift app project. First, our company has an internal solution library. When built, it generates a Static Library in '.a' format, and we use it by connecting the library's Header to the App_Bridging_Header. There's no problem with this part. However, the new feature now includes C++. It also generates a Static Library in '.a' format. So, I tried to use the same method and created an App_Bridging_Header. But an error occurs, and I can't proceed. The first error occurs in the library file: 'iostream' file not found The second error occurs in the App_Bridging_Header: failed to emit precompiled header '/Users/kimjitae/Library/Developer/Xcode/DerivedData/ddddd-glmnoqrwdrgarrhjulxjmalpyikr/Build/Intermediates.noindex/PrecompiledHeaders/ddddd-Bridging-Header-swift_3O89L0OXZ0CPD-clang_188AW1HK8F0Q3.pch' for bridging header '/Users/kimjitae/Desktop/enf4/ddddd/ddddd/ddddd-Bridging-Header.h' Our library is developed in C++ using Xcode, and there's no problem when we run and build just the library project. The build succeeds, and the '.a' file is generated correctly. However, when we try to connect it with the app, the above problems occur. Could there be a problem because we also need to use the existing C library alongside this? The build is successful in an app project created with Objective-C.

Hello. I'm going to create an app that supports purchase records. SwiftData was used to implement storage, backup, and restoration functions at once. One question is whether paging is necessary. When you receive data from a server, you usually implement paging to send and receive data efficiently. In the case of Realm, I know that it uses Lazy data, so I know that there is no need for paging. What about SwiftData? Can the number of data affect performance??

Hi, I'm using CloudKit to create an app that backs up and records your data to iCloud. Here's what I'm unsure about: I understand that the 'CloudKit Dashboard' has 'Security Roles'. I thought these were meant to set permissions for accessing and modifying users' data, but I found there was no change even when I removed all 'Permissions' from 'Default Roles'. Can you clarify? I'd like to know what _world, _icloud, and _creator in Default Roles mean respectively. I would like to know what changes the creation, read, and write permissions make. Is it better to just use the default settings? Here's what I understand so far: Default Roles: _world: I don't know _icloud: An account that is not my device but is linked to my iCloud _creator: My Device Permissions: create: Create data read: Read data write: Update and delete data. I'm not sure if I understand this correctly. Please explain.

Hello, I would like to implement the function of unsubscribe FCM topics that I was subscribing to when I received a specific push from the server. It was implemented through "willPresent" when the app was running, but I don't know how to do it when the app is not running. I activated the 'Background fetch' and 'Remote Notifications' options for now. const message = { notification: { title: 'FCM Topic UnSubscribe', body: 'TestTestTest', }, data: { payload: JSON.stringify(payloadJson) }, apns: { payload: { aps: { sound: 'default', 'mutable-content': 1, 'content-available': 1 } } }, topic: 'unsubscribe_topic', }; Test node code Payload contains the type of topic you want to unsubscribe from. And I added a function to receive push from didReceiveRemoteNotification and handle logic. But this doesn't work. Does Remote Notification (content-available) not work in iOS's Not running and Suspended state?? I'm also using the Notification Service Extension, is this related to it?

Hello, I'm trying to create an app. I'm thinking of an app that can make coin trading convenient. I'm not a cryptocurrency exchange, I'm just trying to use the API provided by the exchange. Do these app violate Apple review guidelines?? As for the app function The user enters the API Key of the exchange. I want to make it easy to provide users with various and convenient transactions through the API Key input. Does the app using the API provided by the Coin Exchange pass the App Store review? I don't see any related apps.. Was it all rejected in the App Store review?? Does the app I think violate the policy below? 3.1.5 Cryptocurrencies: (iii) Exchanges: Apps may facilitate transactions or transmissions of cryptocurrency on an approved exchange, provided they are offered only in countries or regions where the app has appropriate licensing and permissions to provide a cryptocurrency exchange. (iv) Initial Coin Offerings: Apps facilitating Initial Coin Offerings (“ICOs”), cryptocurrency futures trading, and other crypto-securities or quasi-securities trading must come from established banks, securities firms, futures commission merchants (“FCM”), or other approved financial institutions and must comply with all applicable law.

iOS 17.5.1 Xcode WebKit Crash Hello, I have two iPhone devices that I have. These devices are iOS17.5.1, and all Wk related codes cause Crash. Crash occurs when Xcode Build is complete and the app is running. If you run without connecting to Xcode, Crash does not occur. Error: Thread 1: EXC_BREAKPOINT (code=1, subcode=0x19e88fa18) Xcode 15.4, MacBook Pro 14 Sonoma 14.5 There was no issue with iOS 16.5. WKWebsiteDataStore.default() .fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in records .forEach { WKWebsiteDataStore.default() .removeData(ofTypes: $0.dataTypes, for: [$0], completionHandler: {}) } } let webConfiguration = WKWebViewConfiguration()webConfiguration.preferences.javaScriptCanOpenWindowsAutomatically = true

Suppose I received a Privacy Manifest from Apple in the process of reviewing the app. I used "UserDefaults" and "File timestamp APIs" among the APIs, and I didn't add Privacymanifest. And there is nothing in the mail other than "UserDefaults" and "File timestamp APIs". And so is the code. If I remove all the code related to "UserDefaults" and "File timestamp APIs" from the library in this situation, is it okay not to add "Privacy Manifest" from the library as well?? The library can be FrameWork or Static Library.

Hello xcode clang: error: "cannot specify -o when generating multiple output files" I don't think I should after updating Xcode 15.3, where should I check?? I used it well before.

Our team uses a static library (.a) consisting of C and C++. Our team is developing static libraries internally and not sharing them to the outside. Should we still provide 'Privacy Manifest' in this case?? I added the contents of our team's static library (.a) to the app's 'Privacy Manifest' and there was no problem. Nevertheless, if I have to add it separately to the static library (.a), should I create a new framework project itself and not use the .a? Or can I just create a new framework and wrap the .a file??

This is the mail I received from Apple while testing. If you look at it, it shows that there are two items that are problematic. As you can see, "ITMS-91053: Missing API decimation" shows the same problem in both, but the colors are displayed differently. (Purple, Gray) There were four problems in the mail I received while testing more, but all of them received the same color. Is this just a mail error?? Or does the color have a meaning?

Hello. From March 13, 2024, he said he would send an e-mail related to 'Privacy Manifest'. Does Apple send us an email to the review process? Or does it send the app after it is finally released??

Hi. My team is still using GLKit. I have no choice but to keep using it to support non-iOS products as well. (We don't have many developers.) While researching 'Privacy Manifest', I found out that the third party library needs to add 'PrivacyInfo'. I confirmed on Xcode that GLKit is Apple SDKs. Does this mean it's not a third party library? Is using GLKit not related to 'Privacy Manifest'?

Hi, I need a feature in the iOS app that requires updating the user screen via FCM. In other words, I have to update it with no sound and screen display, but this doesn't work. When I remove the notification field, the notification will not be displayed to the user, but the sound will be played. If I remove the sound field, I can make no sound, but the user will be notified. If I remove both, I'm not getting this from the iOS app. How can I solve this?? Which option should I send Push from the server?? I'm also using Notification Service Extension.

Apple requires declaring the use of UserDefaults in both the App and third-party libraries in the PrivacyInfo. However, I also utilize UserDefaults in the Notification Service Extension. Should I treat the Extension as part of the App and only declare it within the App project? Or do I need to separately declare it for the Extension as well?
