When building with 2025.3717 or 2025.3719 for Xcode 16 or Xcode 16.3, I get the following build error. This even happens when I use the sample “Hello World” app. It seems Xcode isn’t happy with the App Icon setup, but the logs don’t really help?
I have tried reinstalling everything, but it still gives the same error. Apparently Xcode’s actool thinks there is no AppIcon set:
Are you able to build with an older version of Xcode and an older version of Solar2D?
Right, building with Xcode 15.x works fine, but Apple is rejecting builds with 15.x since April.
I found the solution: After the whole reinstalls, the iOS simulator 18.4 was not installed any more. I tried building a test project with Xcode, and then it offered to install the simulator. After installing that, it works fine again.
I had the same problem with it not automatically installing the iOS simulator. Totally forgot about that.
