There’s another sideloading option if you’re able to get the ipa file for an app. Check out AltStore. It’s what I currently use and is getting custom sources in the next update. It unfortunately requires a Mac or Windows computer to install and refresh apps though, so not the most elegant solution.
This is a bit of a hack as it relies on free developer accounts with Apple and Apple still signs the apps. In an ideal world, Apple users should be able to install and run anything they want.
Apple doesn't sign them. A free developer account allows you to sign your own apps with a 100 device limit (per employee, if you work at a small company, or unlimited if you pay extra as an "enterprise" developer - which doesn't actually require being a large enterprise. It basically just costs extra).
They only need to sign the app if you want a large team of external beta testers - then you have to send the binary to Apple to be scanned for malware and signed by them.
In Poland/EU we have another fate: so much features of Apple/ios/macOS just doesn’t work/come after 5-7 years from release in USA. For example that’s force me to use google Maps: cycling directions; Public transportation schedule in Apple Maps have released for my city(one of the largest In Poland) just year ago; 3d maps — hah, forget. For air quality I have to use 3rd party app too. Apple Cash? Send money through iMessages? Apple Card? And this list of lack of features that available in USA but not in Poland/Europe are kinda endless.
Yeah that is bs. I can understand that these features probably take a lot of work to build out and to ensure the proper legalities are sorted but Apple is a trillion dollar company so it really shouldn’t take them years
Hopefully, that will not be the case as there is a anti-trust lawsuit possibly coming from DoJ and congress may pass a similar law like DMA. However, the chances are low anything will happen due the upcoming US elections. 😔
