As an app dev im pretty sure you cannot actually compile an iOS app on let's say windows. Although you are free to use things like flutter or KMP and yes your code can be built for iOS on any OS you want, the compiler (the thing that turns code into binary to run on the platform) only exists on MacOS.
So at the end of the day you will need a Mac to be able to actually run your code on an iphone.
I don't think this is super uncommon but in harder difficulties of Terraria, I just play the game as a fishing game. I pretty much exclusively fish for the first few hours of the game and gear up solely through fishing. Then I repeat for the 2nd half of the game as well. I'm also setting up huts in every biome location to do fishing quests.
In the current world when they are done with a release they have to reconcile their internal trunk (main branch) to the external trunk which is the one that everyone can see. This is because currently google do some development internally while other development is done on the public trunk. This reconciliation process can be annoying due to things like "merge conflicts" (ie. A disagreement between two versions of changes about what the final change should be). By doing all work on the internal trunk it should make this reconciliation process much simpler.
No. The latest changes by Google means all incremental work is now no longer visible to the public until a release is done. For most people and developers this shouldn't make a difference.
As an example lets say I implemented features A, B and C and then did a release to v2. Before the changes you would see A get added, then B then C and then the release. With Google's changes you will see nothing for a while and then all of a sudden see A, B, C and the v2 release all at once.
I spray mine with water if they do something really bad. Like bite someone.
