Overview

Hey there, I'm trying to decode an json with an dynamic dict as value. eg. "results": [ { "id": 1799, "created_at": "2024-05-09T14:21:13.289655Z", "updated_at": "2024-05-10T11:54:25.484537Z", "email": "test@test.testh", "name": "Test", "attributes": { "name": { "firstname": "max", "lastname": "mustermann" }, "anboolen": false, "anNumber": 1, "anString": "Test" } } ] The dictionary "attributes" is always an dictionary but the content inside could be everything. for the container of results I already created an struct and using JSONDecoder to decode, but now I have the issue with the attributes part. Can anyone help me with this issue? Thanks in advance!

Our app needs to scan QR codes (or a similar mechanism) to populate it with content the user wants to see. Is there any update on QR code scanning availability on this platform? I asked this before, but never got any feedback. I know that there is no way to access the camera (which is an issue in itself), but at least the system could provide an API to scan codes. (It would be also cool if we were able to use the same codes Vision Pro uses for detecting the Zeiss glasses, as long as we could create these via server-side JavaScript code.)

Hi, I'm looking at being able to set a display colour profile via terminal. I know apps such as SwitchResX are able to change this but i can't figure out how and if it is possible to switch via a terminal command or via a script. This here is what i would like to change. I have googled about and searched through preference files but can't find anything. Any help is much apreciated. Thanks, James

Because it may be quicker to ask: with a TPP, readData() gets a data size of 0 if the process has finished writing to the network. However, there seems to be no way to find out if it has finished reading from the network, other than to do a .write() and see if you get an error. (I filed a FB about this, for whatever that's worth.) Since the API is flow-based, not socket, it's not possible to tell if the app has set its own timeout. Or exited. So one question I have is: if I do flow.write(Data(count:0)) -- is that a possible way to determine if it's still around? Or will it be interpreted as read(2) returning 0? (Putting this in for testing is difficult, but not impossible -- as I said, this might be the quickest way to find out.)

Hello everyone, I looked at various methods how to Unit/UITest SwiftData but I couldn't find something simple. Is it even possible to test SwiftData? Does someone found a solution for that?

Hello everyone My goal is to create Apple's activity ring sparkle effect. So I found Paul Hudson's Vortex library. There is already a sparkle effect, but I don't know how to modify it to achieve my goal. Because I'm pretty new to SwiftUI animations. Does anyone have any idea how I could do this?

I'm defining a typealias for a set, and then creating an extension for the new typealias. When I do this, I'm getting an odd syntax error. Any/all guidance appreciated. typealias IntSet = Set<Int> extension IntSet { func aFunction() -> Set<String> { let array: [String] = self.map { "\($0)" } return Set(array) } } At the return line, I get the following syntax error: Cannot convert return expression of type 'Set<Int>' to return type 'Set<String>' Even if I replace the return line with the following, I get the same compile error return Set("array")

Do we require a Vietnamese bank account to receive payments from in-app purchases for our new educational app being developed in Japan, or will the funds be automatically transferred to our Japanese bank account?

I am in a weird twilight-zone of a git problem in xcode. I specify some files to be staged and it fails to do with no warning of any sort. So I cannot commit them or apply stashed changes to them. I can do it one.file.at.a.time. I have over 11k intermediate files that .gitignore won't ignore, nor stage nor commit to do anything so I could stop tracking them.

Hey A lot of our customers got duplicate push messages twice or more times But we sent only once per push tokens Additionally, devices experiencing the same happens receive similar push messages twice or more from other companies' application This happens is especially reported on devices that have upgraded from iOS 16 to 17. Is there something wrong with the APNS? It

When using the new currentEntitlementTask ViewModifier to check for the status of a non-consumable IAP when should you call transaction.finish()? Also, since currentEntitlementTask will trigger whenever the app/view is run it will call transaction.finish every time. Is it bad to repeatedly call .finish on a already finished transaction? Currently my app works fine when making purchases and using currentEntitlementTask and @Environment to grant access to the purchased content but I know that all the transactions are unfinished and the docs say you should call transaction.finish() to tell StoreKit that you have given the user access to the content. Thanks for any help/advice here.

I try ti create a new project but Xcode don't let me do this... The "Next" button doesn't let me to continue.

I wan't to use Java in Xcode the class file is Main.class. So I set scheme -> run to a script like this: #!/bin/sh java -cp $(dirname $0) Main But when I run it, java said : Error: Could not find or load main class Main Caused by: java.lang.ClassNotFoundException: Main How can I fix this problem? And: It's really helpful to answer in Chinese if you know it.

I'm on VisionOS 1.2 beta and Instruments will capture everything but RealityKit information. RealityKit frames and RealityKit metrics captures no data. This used to work though I'm not sure what version it did. Unbelievably frustrating.

The crash logs for my app show an occasional crash that happens during the launch of the app. The highlighed line is "CoreBluetooth -[CBUUID initiWithData:]. The stack trace ends with "static AppDelegate.$main()". My app does use Core Bluetooth, but there are no Bluetooth related functions in the App Delegate. Also, my app does not use [CBUUID initWithData:] explicitly anywhere. With a stack trace that contains no reference to any of my code, it is extremely difficult to figure out what is going on. I cannot reproduce the crash on any of my own devices. One of my affected users says the app crashes on startup on his phone consistently, even if he deletes and reinstalls it.

After a while I returned to Xcode . I bought a new Mac mini M2 and I installed the Xcode 15.3. To familiarize with the changes in the plataform I follow the tutorial you provide. I create a new iOS app following the instructions. I clicked in the ContentView and I was supposed to see in the canvas a representation of an iPhone running my app. Insteady I saw an error message "Cannot preview in this file - Unexpected error ocurred". I'm blocked in this situation . Do you have a solution for that? The code is provided by your tutorial. I didn't change it. Thanks for your help in this matter. Fernando

My app is showing as size of 2.4 GB on the app store. Its actually 290 mb after fully installed on a device. If any user downloads the app on LTE / cell signal it pops a message saying that the app size is 4.3 GB. App Name : GOHUNT / Research and Huning Maps

Album art in App Store screenshots of music apps: OK or not? The only reason I ask is that I see several apps in the store that feature album artwork by artists like Taylor Swift, The Beatles, Radiohead and so on. Across the internet everyone says this it's a no-no if you don't own the copyright of the images. I get that but what's the deal with all these apps? Are these devs simply taking chances each time they submit for review?
