Apple devices for app development and daily use with Mac

Hello 👋

I think the best setup is to have a dedicated device for every device you are developing for… This means a second iPhone for developing/testing…, a second iPad…

Of course this is “the best” you don’t really need that since there are simulators and macOS partitions to test different OS…

To hear from others with similar work needs, you may be better served by asking in Apple's Developers' forums here:

https://developer.apple.com/forums/

Apple separated those forums from these consumer-focused forums last year, so there are fewer developers left here to see your well-stated question.
