To the person who made the claim, it was the first, because of their limited view of the world. I always take claims of being first with a grain of salt for this reason.
That said, I completely agree. I definitely used remote debuggers and on-device debuggers on mobile before Android/iOS existed.
Then one would say 'it was the first i've seen'
We have language for a reason. Despite what you hear on daytime talk shows about 'your truth', back in reality, actual truth is objective
It is the first they know about. It may be defined differently.
You cannot claim absolute truth on most things you can't can't claim absolute understanding of the language people use to express things.
If you expect absolute truth in a variable world you're in for disappoinment.
