Fuck apple, and fuck xcode.
Making and running android app was a breeze.
Making and running ios app was hell.
Expectation : I should have gotten everything I need just by installing xcode and flutter.

Reality : I need to install these from the terminal : xcode command line tools, homebrew, ruby, cocoapods, firebase-cli. Also I need to manually add many stuffs, such as google login url into xcode project settings. Also we can simply test run our app or install to our device, and iphone we owned, we need to register in apple developer program, fill a full form, blah blah blah.

When it comes to android, I only need to register an account much much later, when I want to publish it to the playstore.
