Apps Script API errors on given ViewController - ios

Question

Has anyone gone through this API and has figured it out?
This is my third time trying to get this to work by following this guide
I am using the swift version of this guide.
Google Apps Script Guide
And it always give me the same errors.
import UIKit
class ViewController: UIViewController {
private let kKeychainItemName = "Google Apps Script Execution API"
private let kClientID = "493692471278-3mf6bo212flgjopl06hrjfeepphe70h4.apps.googleusercontent.com"
private let kScriptId = "Mj0RNm2ZtohFurieBLPwnxYAb4Jnnku4P"
// If modifying these scopes, delete your previously saved credentials by
// resetting the iOS simulator or uninstall the app.
private let scopes = ["https://www.googleapis.com/auth/drive"]
private let service = GTLService() // error Use of unresolved identifier 'GTLService'
let output = UITextView()
// When the view loads, create necessary subviews
// and initialize the Google Apps Script Execution API service
override func viewDidLoad() {
super.viewDidLoad()
output.frame = view.bounds
output.editable = false
output.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 20, right: 0)
output.autoresizingMask = UIViewAutoresizing.FlexibleHeight |
UIViewAutoresizing.FlexibleWidth
// error*** Binary operator '|' cannot be applied to two 'UIViewAutoresizing' operands
view.addSubview(output);

if let auth = GTMOAuth2ViewControllerTouch.authForGoogleFromKeychainForName(
kKeychainItemName,

}
}
// When the view appears, ensure that the Google Apps Script Execution API service is authorized

// The API executed, but the script returned an error.
// Extract the first (and only) set of error details and cast as

} else {

// correct type, based upon what types the Apps Script function

I find it hard to believe that google would make a guide and have it not work for the current version of xcode. It even says at the bottom of their guide that it was last updated February 2016.
Wanted to see if anyone has had any luck with following this guide in the past.
is there another swift guide for this google API?
Thank you in advance.

Answer 1

1)Looks like you aren't getting the header files. You need a Bridging-Header.h. That step is omitted from the Quickstart; see the Google Drive Quickstart for the step you need to take.
2)You can just comment out the following line, it doesn't seem to be necessary.
output.autoresizingMask = UIViewAutoresizing.FlexibleHeight |
UIViewAutoresizing.FlexibleWidth
3)Those changes will fix the compile problems. I found that after fixing the compile problems, it would not link and run on a phone.
The Quickstart guide has you link the GTL.framework with your app using Xcode's 'Link Binary with Libraries'. I instead installed it using Cocoapods (https://cocoapods.org/pods/Google-API-Client) and was then able to run my app.
