How to download Huawei App Store on Apple's mobile phone?

First of all, let me remind you that they are not based on the same system, and the software is incompatible with each other. Apple phones can't install Android software.

Then back to the question itself, Huawei App Store doesn't have a universal version of Android, and it can only find a decompressed version through the network (the installation package decompressed by Huawei mobile phones is generally not used by other brands of mobile phones).

You can search for "Huawei App Store Extraction" in the browser to try to download the installation package.
