Which build mode should I choose?

Question

iOS

No experience in iOS development. I wanted to try to build my first application on Flutter.
Bitrise offers the following build modes:
Save for iOS App Store Deployment
Save for Ad Hoc Deployment
Save for Enterprise Deployment
Save for Development Deployment

How is the first one different from 4? So far, my goal is not to publish the application in the AppStore, but simply to collect it for myself.

Do I understand correctly that if I build it and put the iPhone into developer mode, I can install it directly without the step of publishing to the AppStore?

Answer 1

iOS App Store Deployment - This is if you plan to send the application to the AppStore or Test Flight.
Ad Hoc is for distributing an application to a known end set of devices outside of the AppStore. They are very often used to distribute an application to testers via a third party testing service (eg Firebase Crashlytics).
Enterprise - this is when you have an Enterprise developer account that assumes that you will distribute your product only within the company without the App Store.
Development - used during the development phase of the application. To run the app on simulators and developer devices. In fact, it can be considered that how the application is launched from Xcode.
In order to be able to install the application on other devices without the involvement of Xcode, you will need an Apple Developer account for $99/year. If it is possible to somehow use Xcode or run from Flutter on the developer's iPhone, then you can simply use a free Apple Account (this will be Save for Development Deployment).
