There have been questions regarding if we support Windows and Linux. We currently only officially support Mac since that is what Apple recommends for compilation. That said, we know some people have been successful using Windows especially for android development.
In order to create an IOS application, you will need to create an iOS .p12 Distribution Certificate and iOS Provisioning Profile. While it is possible to create an IOS distribution certificate and provisioning profile on a windows machine, there is no official Apple documentation on this topic and we can not provide support for this.
Our recommendation is to research "iOS Distribution Certificate windows" which will involve generation of a .p12 file and likely use of OpenSSL. Post your learnings here to the forum so everyone can benefit.
