Client library (iOS 13.0+ or MacOS 10.15+) for accessing your Cumulocity IoT tenant from your own iPhone or Mac apps.

Refer to the Cumulocity Home Page to sign up for your own Cumulocity tenant if you do not already have one.

This library uses the c8y REST API in order to communicate with your tenant and you will need a login with appropriate permissions to allow access.

You will need a Mac (ideally running 10.15) and up to date version of xCode 11.0 to use this library and integrate with your apps.

Install the library direct from github or as a swift package in a xcode project that you have already created.

Using Xcode 11 go to File > Swift Packages > Add Package Dependency Paste the project URL: https://github.com/johnpcarter/c8y-ios-lib Click on next and select the project target, choose latest branch

Now you can import your dependencies e.g.

import Combine
import Cumulocity_Client_Library

Connectivity and basic usage

You first need to create a Connection object and then one of the API Service classes to interact with you Cumulocity tenant, e.g.

let conn: C8yCumulocityConnection = C8yCumulocityConnection(tenant: "<mytenant>", server: "cumulocity.com")

		conn.connect(user: "john", password: "appleseed").sink(receiveCompletion: { (completion) in
				switch completion {
				case .failure(let error):
					print("Connection refused! - \(error.localizedDescription)")
					print("Connection Success")
					// Now that we have tested the connections, lets fetch some managed objects
					C8yManagedObjectsService(conn).get(pageNum: 0).sink(receiveCompletion: { (completion) in
						switch completion {
						case .failure(let error):
							print("Get Failed \(error.localizedDescription)")
							print("Get Completed")
					}, receiveValue: { results in
						if (results.status == .SUCCESS) {
							print("page \(results.content!.statistics.currentPage) of \(results.content!.statistics.totalPages!), size \(results.content!.statistics.pageSize)")
							for object in results.content!.objects {
									print("\(String(describing: object.id))")
					}).store(in: &self._cancellableSet)
		}, receiveValue: ({ userInfo in
			print("User name is \(userInfo)")
		})).store(in: &self._cancellableSet)

The above first verifies the connection and uses the C8yManagedObjectsService class to fetch a page of C8yManagedObject objects. The connection object does not carry state and the connect method is only useful to verify the credentials and also gather information about the user C8yUserProfile. Each call via the Service classes reconnects via the connection credentials and is stateless.
