Counterpoint: both Xcode and Visual Studio are much slower for certain things than Visual Studio Code (most notably: startup time). Application performance is less a technical problem than an organizational and cultural problem (at least if performance has become so bad that it starts to be annoying - e.g. I'm sure at some point in the past both Xcode and VS started much faster than now, and on much slower computers). If the team cares about performance they will find ways to improve it no matter the technology they use, they "just" need to make time for performance investigation and optimizations. There's usually a lot of low hanging fruits to pick before switching to a more efficient tech stack will enable further improvements (and at that point you're probably deep in diminishing returns territory).
