[Development] Is it possible to submit my Qt application for iOS to Apple App Store?

Looks like Qt 5 for iOS uses static linking. But I have commercial, 
closed source application. I don't want to provide source code, object 
files, etc.
If I got this right, I can't use LGPL version of Qt for iOS development 
and I need to by commercial one. Right?

Are there any exceptions in LGPL license of Qt for iOS development that 
allows us to use static linking?

> Yes, you can submit your Qt-based application to the iOS App Store, this is officially supported by Qt. It's true that you cannot use dylibs if you want your application to run on iOS 7.x or earlier. Future versions of iOS will lift this restriction.

> Statically linking LGPL-licensed code such as Qt in your application also has certain legal requirements. If your application is open source, there is no step 2. However, if your application is closed source, the LGPL license dictates that you must provide a way for end users to re-link with a different version of Qt. Generally you'd fulfill this license requirement by providing the necessary object files and Makefiles to rebuild your application. In either case you must also provide attribution that you used Qt (in your about page or in the documentation somewhere). If these requirements are not suitable for your application, you may instead purchase a commercial Qt license from Digia here: http://qt.digia.com/buy/
