Looking for some advice: we are planning to create a hybrid app for both iOS and Android; this app will consume a REST API. We are looking for a tool for this development with the following attributes:
Shallow learning curve; easiness to adopt (all team is new into mobile development, with diverse backgrounds: Java, Python & AngularJS),
Easiness to test (we discarded Angular-based tools already: creating a unit test in Angular we considered time-consuming and low value. At this point of the project, we cannot afford UI testing with Selenium/Appium based tools).
So far, we are not considering any specific capability of the device. Still, in the mid/long term, we would require the usage of GPS (geolocalization) and accelerometer (not sure if it's possible to use it from a hybrid app). Suggest any other tool if you wish.
If your team has a strong background in Python and you want to release some prototype soon, you could try Python and Kivy. Kivy is an open-source, cross-platform Python framework for rapid development of mobile GUIs. It supports both iOS and Android. I have passed a similar situation recently: to start a mobile app with no background in mobile development. Kivy saved me a lot of time. I could develop a prototype and release it faster than I thoght.
To be honest , You need to think these points :
My vote for now is going with React Native with Expo , using Typescript...
With this stack You could follow some patterns and principle that the Java and python programmers are familiar with.
With Expo you need to concern only with the shared layer (Typescript) and the Native ones will be expo responsibility.
Please check Expo.com and try to get started using typescript.
Good performance and with EAS (paid plan) you can create a full CI CD pipeline for your app connected to the stores(Apple and Android).
