There's more to pricing than simply applying the current exchange rate to your prices at the time a new product releases. Companies will often price products a cheaper in less wealthy countries where people have less disposable income.
Take Japan for example, a country with a
relatively low amount of disposable income when compared to the US - 33k USD in Japan vs 54k USD in the US per person per year. The 14 Pro is priced at 149.800 Yen over there, which includes 13.618 Yen in taxes. Convert the pre-tax price into USD and the iPhone 14 Pro in Japan comes out to roughly $916 before taxes. So while we'll have a hard time describing it as cheap, it's still almost $100 cheaper in Japan than it is in the US.
The point is, while you're right that the currency exchange rate obviously has a big influence, it's not like Apple has to raise prices. They have to consider the impact on demand when raising the prices and then decide whether the reduced demand with higher profit margins makes up for the higher volume they could sell at a lower price.
