> At first, Xcode itself wasn't exactly free, because it was bundled with the OS updates, which cost a decent amount back then. Xcode and Mac OS X were included on disc with Mac hardware. This is how I became a developer. When Mac OS X was released, that was the period when Apple truly embraced open source and Unix. Since iPhone, however, there's been a lot of backtracking in that area, which I find very unfortunate. In general, macOS is becoming more and more like iOS. Consequently, it is becoming more hostile to openness.
