You can make a release only on your github page, not on Daedalia's or mine.
I did just that yesterday
https://github.com/dresserr/openxcom-ios/releases, I just had some doubts about the version designation, to avoid confusion and the possible mismatch between the content of the release and the source code.
let me also take advantage of the opportunity to repeat my question, which has not yet been answered - is that the game running in the Xcode emulator does not recognize my physical and on-screen keyboard, so it is not possible to write the name of the base when creating it and test the game further, there is there a way to fix it? I always have to download it to my phone, but my free developer certificate has critical limitations.
