Description

As we discussed on Slack I'm just sending some sample code to potentially add to the GitHub readme for the swift sdk. The physical docs don't have examples, so I'm not sure if it is worth it to have some of the pages with example code and others without. However, some of this could certainly be added to the README.md to provide a few more complicated examples / walk through how to set it up in the project.

At the top of every file put:
import StitchCore
import StitchRemoteMongoDBService
(Do not think we need MongoSwiftMobile quite yet)

1. Inside of AppDelegate.swift:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
do

{ stitchClient = try Stitch.initializeAppClient(withClientAppID: "stitch_appid") }

catch

{ print("Unable to connect to stitch client") }

return true
}

2. To Login With Anonymous Credentials:

stitchClient.auth.login(withCredential: AnonymousCredential()) {result in
switch result {
case .success(_):
print("Stitch User ID: " + stitchClient.auth.currentUser!.id)
DispatchQueue.main.async

{ // update UI accordingly }

case .failure(let error):
print("failed logging in Stitch with Facebook. error: (error)")
}
}

3. To Login with another Credential (Facebook):

// At The top of the page
import FacebookLogin
import FBSDKLoginKit
import StitchCore

// In viewDidLoad()
let loginButton = LoginButton(readPermissions: [ .publicProfile, .email, .userFriends ])
loginButton.center = view.center
view.addSubview(loginButton)

// In viewWillAppear() --> will call after Facebook successfully logs in
if let accessToken = FBSDKAccessToken.current() {
let credential = FacebookCredential.init(withAccessToken: accessToken.tokenString)
stitchClient.auth.login(withCredential: credential) {result in
switch result {
case .success(_):
print("Stitch User ID: " + stitchClient.auth.currentUser!.id)
DispatchQueue.main.async

{ // update UI accordingly }

case .failure(let error):
print("failed logging in Stitch with Facebook. error: (error)")
}
}
}

4. Throughout the rest of the application, to get access to the defaultStitchClient just call:

private lazy var stitchClient = Stitch.defaultAppClient!

5. To Perform a Find:

mongoClient = stitchClient.serviceClient(fromFactory: remoteMongoClientFactory, withName: "mongodb-atlas")
collection = mongoClient?.db("db_name").collection("collection_name")
collection.find(["filter_key": "filter_value"], options: RemoteFindOptions(limit: 3, sort: ["title": 1])).asArray({ result in
switch result {
case .success(let result):
results.forEach({ document in
guard let arr_of_sub_docs = doc["arrDocs"] as? [Document] else

{ print("Error: no array of subdocuments found") exit(0) }

print(arr_of_sub_docs[0]["subdoc_field"])
})

case .failure(let error):
print("Error in finding documents: (error)")
}
})

6. Perform a Function Call:

stitchClient.callFunction(withName: "insertFunctionName", withArgs: ["args"], withRequestTimeout: 5.0)
{(result: StitchResult<String>) in
switch result

{ case .success(let stringResult): print("String result: \(stringResult)") case .failure(let error): print("Error retrieving String: \(String(describing: error))") }

}

7. Insert a Document

var newDoc = Document()
newDoc["name"] = stitchClient.auth.currentUser?.profile.name! as! String
newdoc["user_id"] = stitchClient.auth.currentUser!.id
itemDoc["title"] = "newDocTitle"
itemDoc["arrOfSubDocs"] = []
self.groupCollection?.insertOne(itemDoc, {result in
switch result

{ case .success(_): // Do Something case .failure(let error): print("failed logging out: \(error)") }

})

8. Update a Complicated Document (push a subdocument into an array):

var newSubDoc = Document(["title": "newSubDocument"])
var filterDoc = Document(["$push": Document(["arrOfSubDocs": newSubDoc])])
collection.updateOne(
filter: ["_id": subDoc["_id"] as! ObjectId],
update: filterDoc,
options: RemoteUpdateOptions(upsert: true),
{result in
switch result {
case .success(_):
DispatchQueue.main.async

{ // Update UI or perform transation }

case .failure(let error):
let alert = UIAlertController(title: "Update Failed", message: error.localizedDescription, preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default,handler: nil))
self.present(alert, animated: true)
}
}
)
