Hey @klyni_gg I ran into the same roadblock when I wanted to test a couple of App Store-only apps on my Mac. The Xcode simulator is great for development, but yeah, it won’t let you access the App Store or install regular iOS apps.
What helped me was using Apple’s “sideloading” feature on M1/M2 Macs. If the app you want was ever downloaded on your iPhone using the same Apple ID, you can try installing it via the Mac App Store under your purchased items.
It doesn’t work for every app (developers can opt out), but I was able to run a few iPhone-only apps this way, no third-party tools needed.
Hope this was helpful
