creating a reusable networking layer in a swiftui crypto app is essential for managing api calls, handling responses, and maintaining clean architecture. in this tutorial, we will build a simple networking layer that can be reused throughout our swiftui application. we will also demonstrate how to integrate this networking layer into a swiftui app that fetches cryptocurrency data.

step 1: set up your swiftui project

1. **create a new project**: open xcode and create a new swiftui project.
2. **organize your project**: create a new folder in your project called `networking`.

step 2: define the network manager

we'll create a `networkmanager` that will handle all api requests. this class will be responsible for fetching data from a cryptocurrency api (for example, coingecko).

create `networkmanager.swift`



step 3: create the crypto model

next, we'll create a model to represent the cryptocurrency data. for this example, we'll fetch a list of cryptocurrencies.

create `crypto.swift`



step 4: create a view model

the view model will use the `networkmanager` to fetch the crypto data and expose it to the swiftui views.

create `cryptoviewmodel.swift`



step 5: create the swiftui view

now, we will create a swiftui view that displays the list of cryptocurrencies.

create `contentview.swift`



step 6: set the entry point

make sure your `@main` struct points to the `contentview`.

update `yourappname.swift`



step 7: run your app

1. build and run your app in the simulator or on a device.
2. you should see a list of cryptocurrencies displayed with their current prices.

conclusion

you have now created a reusable networking layer for your swiftui crypto app. this architecture allows you to easily fetch data from any api and handle the responses cleanly. you can expand this networking layer to include more features, such as handling different http methods, adding headers, or integrating error handling strategies.

feel free to customize the model, vie ...
