📚 General info

• NASA Mars Rover Photos from the NASA API. Note video function requires npm module safe-pipe
• NASA Mars Photos API github repo
• This mobile app was created following the MVVM framework. The Model is responsible for making calls to the API and fetching the json data.

💾 App Setup

• Get yourself a NASA API key from Nasa
• Once you copy the Xcode peoject you will still need to create an additional swift file. The file should be called Constrant.swift and have the code

import Foundation

class Constrant{
    static var url : URL{
        guard let url = URL(string: "https://api.nasa.gov/mars-photos/api/v1/rovers/perseverance/latest_photos?api_key=") else{ fatalError()}
        
        return url
        
    }
    
    static var session:URLSession {
        let session = URLSession(configuration: .default)
        return session
        
    }
    static var request: URLRequest{
        let req = URLRequest(url: url)
        return req
        
    }
    
    static var decoder: JSONDecoder{
        
        let decoder = JSONDecoder()
        decoder.keyDecodingStrategy = .convertFromSnakeCase
        return decoder 
    }   
}

• Make sure to enter your uniqe API key in the url after "api_key=". There should not be any space between the = and the API key. Ex. "https://api.nasa.gov/mars-photos/api/v1/rovers/perseverance/latest_photos?api_key=hyfMbZoL58adaasdadad4234"

💻 Code Examples

• API.swift extract: gets data from Nasa API using APIKEY supplied by them.

import Foundation

class API {
    class func getImage(_ onSuccess: @escaping ([LatestPhoto]) -> ()){
        Constrant.session.dataTask(with: Constrant.request){(data, res, err) in
            guard let data = data, err == nil else{
                fatalError()
            }
            do{
                let apod = try JSONDecoder().decode(LatestPhotosWrapper.self, from: data)
                
                
                DispatchQueue.main.async {
                    onSuccess(apod.latestPhotos)
                }
                
            }
            catch{
                print(error)
            }
            
        }.resume()
        
    }
}
