I saw that QGIS now works on Android, any chance there will be an iOS version?
Highly unlikely even in the event of a sponsor or technical feasibility.
The reason has to do with licensing. The web is filled with articles about GPLv2 and Apple Appstore compatibility and even for the cases where they do make it through, there are several examples of copyleft licensed open source projects that were pulled off the app store.
A couple of reasons:
- No one has made a build for that platform.
- The App Store the GPL are incompatble. QGIS is GPL Reference Reference
- Because of 2. the only way to get an application on iOS without the App Store is via jail breaking which isn't normally what people like to do
QGIS has a lot of copyright holders and the only way to change the licence (not that it should) to something that would allow it in the App Store is getting everyone's permission which I can tell you will not happen.
