I'm have an SKTexture generated by a GKNoiseMap. When I look at the texture in a swift playground, it has the expected colours. When I apply the texture to a material and render it in a SCNView, the colours are different (see images below). What am I doing wrong?

Full code:

Xcode 11-12, MacOS Catalina, Swift 5 project...

This code is produced "Context leak detected, msgtracer returned -1" error:

I'm try to use Firebase with Xcode 12, but I'm facing this warning after install and run the project.

'generateIdentityVerificationSignatureWithCompletionHandler:' is deprecated: first deprecated in iOS 13.5 - API deprecated. Use fetchItemsForIdentityVerificationSignature: and the teamPlayerID value to verify a user identity.

any idea how I can fix this issue?

here the code:

Something is preventing my game from connecting to a server, and it fails to get approved the Appstore Review Team.

The game was released on GooglePlay and successfully works from all Android devices, even from Linux and Windows. IPv6 networks are working too. The game is using NetworkTransport, which works in my case on Sockets (not Websockets)

I've successfully tested, connected and played the game on:

• my developer iPhone 5 (iOS 12.4.6) on IPv4 network in United Kingdom (I don't have IPv6 operator)
• Xiaomi Redmi Note (Android 10) on IPv4 and IPv6 network in Moscow, Russia.
• PC (Ubuntu 20.04) on IPv4 and IPv6 network
• PC (Windows 8) on IPv4 and IPv6 network in Moscow, Russia.
• PC (Windows 10) on IPv4 in United Kingdom

I have 3 VPS servers:

• Russia, Moscow - IPv4 and IPv6 (listening to port 17777)
• Germany, Frankfurt - IPv4 and IPv6 (listening to port 17777)
• USA, New York - IPv4 and IP6 (listening to port 17777)

Client uses some random port, assigned by OS.

The game is made to always connect to the servers that have static IP addresses, it's not using peer-to-peer and the client always initiates connection, not server (...so NAT shouldn't be an issue)

Connection happens directly by IP address, not by DNS request. There are no SSL certificates involved, no encryption. Ping works properly from my office desktop towards all servers (both IPv4 and IPv6 ping).

If there is no internet connection, the game is coded to throw a popup and pause. But when AppStore Review Team launches the game, it somehow thinks that there is internet connection. Yet when it tries to establish connection, both IPv4 and IPv6 networks simply timeout.

Maybe, when compiling the project on XCode, I missed some build options? Maybe there is some permission / "capability" I need to add?

How can it seems work everywhere, but not in AppStore Review Team headquarters?

I even added NSAllowArbitraryLoads key to the .plist file, yet it seems AppStore iPads can't talk to my server. They are running on iOS 13.5.1 on Wi-Fi.

here is my plist:

I am somehow experiencing a EXC_BAD_ACCESS error when trying to dynamically allocate a c++ class object at runtime using the newkeyword on a .mm file with the compiler set to objective-c++. Any help or direction with this would be greatly appreciated! I had zero problems when I ran this game in its native c++ project file.

This is a follow up to my previous question here however this question should be able to stand alone. I get the following error when I try to import tensorflow while there exists a file containing from tensorflow import keras.

I am having trouble finding information in the standard GameKit documentation on how does a player advertise that they want to join some match? There is documentation on how to create a match and invite waiting players, but I can't decipher how does a player advertise to join a match and become this "waiting" player?

Here is a link to Apple's documentation https://developer.apple.com/library/archive/documentation/NetworkingInternet/Conceptual/GameKit_Guide/MatchmakingwithGameCenter/MatchmakingwithGameCenter.html

I currently have a struct in which my ViewController references to return a random value from a group of arrays (aList, bList, cList, & dList). I ideally would like to be have aList always enabled while being able to toggle bList, cList, & dList on/off.

I have all this in a struct (shown below) but I'm very new to Swift and am learning that structs are "value types" while the ViewController is a "reference type" and apparently UI objects can only be referenced from reference types?

I'm trying to receive messages in GameKit. The part of receiving the messages works well, but I can not figure out how to decode the data properly.
