Hi !I developed a paid application that I offer on the Apple Store.Is it possible to offer licenses to users to access the software without paying? With my thanks,FR

Hello, I'm trying to transpose to iOS a qt + opengles 3.0 application that runs without any problem on Windows, Linux, Android and macOS. The openGL display remains black in the iOS simulator... There is no error in the logs and there are no Opengl errors. I added <Key>PrefersOpenGL>/key> <True/> in the plist of the application but it doesn't change anything. Does anyone have any ideas? Thank you! PS: I'm using Qt 5.15.0 with ios 13.2

Hello, Is there an easy way to compile a project defined by a makefile.txt with XCode? Thanks !

Hello, I'm currently selling an app on the Apple Store but I think I made a mistake. I would have preferred to offer a free trial version on the store and allow the purchase of a full version license from an in-App purchase. Is this possible? Is it possible to make the application free on the store and offer an in-App to get the full version? And how to manage people who have already purchased the paid version from the store (i.e. convert an application purchase into an In-App)? Also, I would like to offer an iOS version of my app. Can I set a different price for the macOS and iOS versions?

Hello, I have a big problem... I first proposed a paid application on the Apple Store. Then, I realized that offering it as a freemium would be more efficient (offering a free version and then proposing a full version as an in-App). The problem is "how do I know if the user has already bought the initial full version from the store)? It seems that QtPurchasing can only handle In-Apps but can't tell if the application itself has been purchased... How to do it ? Thanks !

Hello, I am making my first iOS application. Everything works fine with iOS simulator but when I try to test on real devices (using browserstack.com as I don't have one personally), the app closes at startup, after a few seconds. The log shows this: May 31 15:12:45 runningboardd(RunningBoard)[31] <Notice>: XPC connection invalidated: [application<net.winstars>:632] May 31 15:12:45 runningboardd(RunningBoard)[31] <Notice>: XPC connection invalidated: [application<net.winstars>: <RBSHereditaryGrant| endowmentNamespace:com.apple.boardservices.endpoint-injection UIScene:com.apple.frontboard.systemappservices::com.apple.springboard>, May 31 15:12:45 runningboardd(RunningBoard)[31] <Notice>: XPC connection invalidated: [application<net.winstars>: <RBSHereditaryGrant| endowmentNamespace:com.apple.frontboard.visibility UIScene:com.apple.frontboard.systemappservices::com.apple.springboard> May 31 15:12:45 runningboardd(RunningBoard)[31] <Notice>: XPC connection invalidated: [application<net.winstars>: ]> May 31 15:12:45 runningboardd(RunningBoard)[31] <Notice>: Assertion 31-58-1055 (target:[application<net.winstars>:632](UIScene:com.apple.frontboard.systemappservices::sceneID%3Anet.winstars-default)) will be created as active May 31 15:12:45 runningboardd(RunningBoard)[31] <Notice>: Calculated state for application<net.winstars>: none (role: UserInteractiveNonFocal) May 31 15:12:45 runningboardd(RunningBoard)[31] <Error>: RBSStateCapture remove item called for untracked item <RBProcessMonitorObserver| qos:0 qos:(null) configs:{ May 31 15:12:45 runningboardd(RunningBoard)[31] <Error>: }> May 31 15:12:45 runningboardd(RunningBoard)[31] <Notice>: Finished acquiring assertion 31-58-1055 (target:[application<net.winstars>:632](UIScene:com.apple.frontboard.systemappservices::sceneID%3Anet.winstars-default)) May 31 15:12:45 mDNSResponder[134] <Notice>: [R104] DNSServiceCreateConnection STOP PID[632](WinStars) May 31 15:12:45 appstored[169] <Notice>: StoreKitServiceListener: Connection to WinStars invalidated May 31 15:12:45 SpringBoard(FrontBoard)[58] <Notice>: Workspace connection invalidated for <FBApplicationProcess: 0x134843770;

The problem is that I don't understand it.

With my thanks, Franck ps: I develop the program using QT 5.15.2
