From my experience working with mobile platforms, it’s not as straightforward as just running APK apps on iOS devices. iOS uses the IPA file format exclusively, while APK files are designed specifically for Android. There are tools like Cider or iEMU that claim to let you run APK apps on iOS devices, but these aren’t officially supported. Plus, they usually require jailbreaking your device, which can be risky and may void your warranty. So, if you’re hoping for a simple way to run APK apps on iOS devices, unfortunately, it doesn’t really exist.
