Agents are happier working on any codebase, but ultimately Shopify and other companies want iOS native app level quality without the huge cost of hiring many native iOS / Android devs.
LLMs and Agents deliver on getting a native app out at lower cost, higher quality, faster all at once.
I think everyone is trying to tell you your skills as an iOS native dev have been commoditised and Shopify and others don't need to hire anymore native devs to find this out.
I don't see how your job being completely commoditised and cannibalised by LLMs replacing your job is some how vindication?
This is just like saying "we won the argument", but what did you actually "win"?
