4. © JAMF Software, LLC Introduction to Swift for iOS Agenda: What are we going to do? What do we need to do it? Let’s code!
5. © JAMF Software, LLC What are we going to do? Create single view app Use app configuration to pass data to the app
6. © JAMF Software, LLC What do we need to do it? Xcode Apple Developer Account (paid) Jamf Server - to distribute the app iOS device - to test the app
7. © JAMF Software, LLC Let’s code! Download starter project. - https://github.com/BIG-RAT/JNUC2019 Click userAssignStarter.zip
8. © JAMF Software, LLC Let’s code! Unzip the download and Launch Xcode - Add developer account, if available Click the Download button.
9. © JAMF Software, LLC Arrange the layout so that both the code and device are visible.
10. © JAMF Software, LLC Two ways to link the user interface to the code. Control, click and drag.
11. © JAMF Software, LLC Provide a name for the object. And code to color the background. class ViewController: UIViewController { @IBOutlet var main_UIView: UIView! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. main_UIView.backgroundColor = UIColor(red: 0x5C/255.0, green: 0x78/255.0, blue: 0x94/255.0, alpha: 1.0) } }
12. © JAMF Software, LLC Build and run the app.
13. © JAMF Software, LLC Things to remember when adding objects: ⇧+⌘+L - to bring up the object library (and select one item). ⌥+⇧+⌘+L - to bring up the object library (must be manually dismissed).
14. © JAMF Software, LLC Inspectors useful when working with objects: Show/Hide Inspectors Attributes inspector Size inspector Connections inspector (what code is connected to the object)
15. © JAMF Software, LLC Position constraints when working with objects. Alignment / centering Positioning / dimensions
16. © JAMF Software, LLC Add content to the user interface. To add a label, click and drag from the objects library.
17. © JAMF Software, LLC Position content on the user interface. Set top margin Fixed height / width Center horizontally
18. © JAMF Software, LLC View the restrictions in the Navigator window.
19. © JAMF Software, LLC Add a Text Field and Button, adjust to taste. Suggestions: Text Field: Fixed top margin Variable Width - fixed right and left margins Centered Button: Constraints similar to the Label White Text Color
20. © JAMF Software, LLC Attach the text field to the code. Control click and drag
21. © JAMF Software, LLC Add an action to the Submit button. Control click and drag
22. © JAMF Software, LLC And the action (function). @IBAction func submit_Button(_ sender: Any) { name_TextField.text = "Hello JNUC 2019!" }
23. © JAMF Software, LLC Giving a run…
24. © JAMF Software, LLC Take a breath… If need be, download the updated project: https://github.com/BIG-RAT/JNUC2019/blob/master/helloJNUC.zip Grab code to further update the project: https://github.com/BIG-RAT/JNUC2019/blob/master/ViewController.swift.zip
25. © JAMF Software, LLC Note changes to submit_Button function: Defined xml needed to update the device record. Defined endpoint and credentials for the update. Added code for API operation. Note changes to viewDidLoad function: Check for and parse app configuration data if present. Provide test data when app configuration is not present.
26. © JAMF Software, LLC We need an account on the Jamf Server with at least the following permissions:
27. © JAMF Software, LLC Testing…
28. © JAMF Software, LLC Before uploading to the server, let’s get things set up with Apple. Log into the developer portal and click Certificates, IDs & Profiles
29. © JAMF Software, LLC Click Devices and either add or register a device, if needed.
30. © JAMF Software, LLC Register new…
31. © JAMF Software, LLC Build the app for distribution. Add developer account to the app for signing.
32. © JAMF Software, LLC Set the target device to Generic iOS Device, click Product, then Archive.
33. © JAMF Software, LLC Distribute App
34. © JAMF Software, LLC Select Developer, then Next
35. © JAMF Software, LLC Next
36. © JAMF Software, LLC Next
37. © JAMF Software, LLC Export, selecting a location to save the Archive
38. © JAMF Software, LLC Add the app to the Jamf Server. Use the jamfsoftware database for hosting. Click Upload App and select the ipa file from the recent Archive.
39. © JAMF Software, LLC Scope the app as desired, then add the app configuration and deploy.
40. © JAMF Software, LLC
41. © JAMF Software, LLC Time to sharpen it up a bit by adding an icon.
