I am trying to integrate Firebase backend to my app.
Created my podfile with
pod 'Firebase'
Everything looks fine with the sdk import
In my first view controller I do:
import Firebase
override func viewDidLoad() {
super.viewDidLoad()
let ref = Firebase(url: "https://<YOUR-FIREBASE-APP>.firebaseio.com")
ref.authAnonymouslyWithCompletionBlock { error, authData in
if error != nil {
// There was an error logging in anonymously
} else {
// We are now logged in
}
}
}
But i got an Can not call value of non-function type error
Thanks in advance
So they have changed the way you install Firebase with pods, Now instead of just adding pod 'Firebase' you must add the individual pods like this.
use_frameworks!
target “Your Project” do
pod 'Firebase/Core’
pod 'Firebase/Database’
pod 'Firebase/Auth’
end
However, you only need to put 'import Firebase' and it will cover all pods relating to Firebase. And don't forget to configure Firebase in the didFinishLaunchingWithOptions method of your AppDelegate!
FIRApp.configure()
Good Luck!!

I have try everythng and I have imported pods to my project, done it several times in several new projects, but always get this error:
'Cannot call value of non-function type 'module'
Is it possible that my cocoa-pods are damaged somehow?
When I insert this code:
import Firebase
let BASE_URL = "my_project_url"
var FIREBASE_REF = FIRDatabase.database().reference()
I can see in Output/Debug window that I am connected with firebase, but when I start with code:
let BASE_URL = "my_project_url"
let FIREBASE_REF = Firebase(url: BASE_URL)
var CURRENT_USER: Firebase
{
let userID = NSUserDefaults.standardUserDefaults().valueForKey("uid") as! String
let currentUser = Firebase(url: "\(FIREBASE_REF)").childByAppendingPath("users").childByAppendingPath(userID)
return currentUser!
}
always get error. I have really try stuff from a lot tutorials, I tried a lot of things over past few days and nothing happened.
I have also look and read this topics, but did not help:
Cannot call value of non-function type 'module'
xcode error : Cannot call value of non-function type module Firebase
Unable to connect Firebase to my Xcode swift app?
I have open many new projects, done it import pod many times, I have import pod with insert in my pod file:
pod "Firebase"
and like this:
pod "Firebase"
pod "Firebase/Database"
also tried like this:
pod 'Firebase', '>= 2.5.1'
pod "Firebase/Database"
but always the same problem. Pods are inserted, I see Firebase folder and I know this is OK, so what could be wrong?
Like I said, I see that I am connected with Firebase in Debug window, as soon I start coding, error appears, and it is in every project like this, even when I try different approach and different code.
Any ideas?
You're either using the wrong version of Firebase, or following the wrong guide, depending on what you're trying to do.
Your pod config will install the latest version (3.2.1) while the code you've written is for 2.5.1 and before.
I'm developing app with firebase with swift.
I got error when using FDataSnapShot.
Here is my code.
DataService.dataService.DATA_REF.observeEventType(.Value, withBlock: {
snapshot in
var newItems = [FDataSnapshot]()
// loop through the children and append them to the new array
for item in snapshot.children {
newItems.append(item as! FDataSnapshot)
}
// replace the old array
self.items = newItems
})
I installed firebase sdk with cocoapods.
My pod file looks like this.
use_frameworks!
pod 'Firebase'
target 'nos' do
end
Is there anybody who has experience in this?
*Note: I'm using the latest version of Xcode(7.2).
I really hope to hear from you soon.
If you're attempting to use on a UIViewController, make sure you add:
import Firebase
to YourViewController, clean cache (ctrl+k), and rebuild (ctrl+b) after you've added the CocoaPod to your project.
I am following the Analytics for iOS (developers.google.com/analytics/devguides/collection/ios/v3/?ver=swift) guide and I've got errors in my Swift code Project that I can't fix.
I am working with XCode 6.4, Swift and the iOS Deployment Target 8.1.
Step 1
First I installed a Google SDK using CocoaPods.
This is the console result after running pod install command:
Updating local specs repositories
CocoaPods 1.0.0.beta.2 is available.
To update use: `gem install cocoapods --pre`
[!] This is a test version we'd love you to try.
For more information see http://blog.cocoapods.org
and the CHANGELOG for this version http://git.io/BaH8pQ.
Analyzing dependencies
Downloading dependencies
Using Google (1.0.7)
Using GoogleAnalytics (3.14.0)
Using GoogleNetworkingUtilities (1.0.0)
Using GoogleSymbolUtilities (1.0.3)
Using GoogleUtilities (1.1.0)
Generating Pods project
Integrating client project
Sending stats
Pod installation complete! There is 1 dependency from the
Podfile and 5 total pods installed.
Step 2
Then opened, as said in the guide, my app's Project .xcworkspace file.
My Podfile looks like this:
# Uncomment this line to define a global platform for your project
# platform :ios, '8.0'
# Uncomment this line if you're using Swift
# use_frameworks!
target 'XXXXXX' do
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.1'
pod 'Google/Analytics', '~> 1.0.0'
end
target 'XXXXXXTests' do
pod 'Google/Analytics', '~> 1.0.0'
end
Where XXXXXX is my Project's name.
Step 3
I got the configuration file GoogleService-Info.plist and included in my Project adding all the targets (2 targets in my project).
Step 4
I created a BridgingHeader by by choosing File > New > File > iOS > Source > Header File.
I named it BridgingHeader.h and is in the root of my Project.
The content is:
#ifndef XXXXX_BridgingHeader_h
#define XXXXX_BridgingHeader_h
#import "Google/Analytics.h"
#import <Google/Analytics.h>
#include "GAI.h"
#import <CoreData/CoreData.h>
#import <SystemConfiguration/SystemConfiguration.h>
#import "Libraries/GoogleAnalytics/GAI.h"
#import "Libraries/GoogleAnalytics/GAIFields.h"
#import "Libraries/GoogleAnalytics/GAILogger.h"
#import "Libraries/GoogleAnalytics/GAITracker.h"
#import "Libraries/GoogleAnalytics/GAIDictionaryBuilder.h"
#endif
Where "XXXXX" is my Project's name.
Step 5
Now the problems:
I tried to include/import the Google Analytics into my AppDelegate.swift but I can't. This is the error:
AppDelegate.swift import Google Analytics
I also tried import "Google/Analytics.h" but another error appears: Expected identifier in import declaration.
How can I fix this so XCode doesn't give me errors?
Is the BridgingHeader wrong? Do I have to point at this somehow to recognize its inner headers?
Do I have to configure something else for the Google Analytics that I am missing right now?
Thank you very much.
There are two options for implementation with Google Analytics using CocoaPods.
pod 'Google/Analytics'
pod 'GoogleAnalytics'
There are pros and cons between them.
pod 'Google/Analytics'
need google configuration file(GoogleService-Info.plist)
simple bridging header file. Just add #import <Google/Analytics.h> in bridging header file.
add import Googlein every file you want to implement google analytics.
pod 'GoogleAnalytics'
no google configuration file(GoogleService-Info.plist)
more complex bridging header file.
I prefer to use pod 'GoogleAnalytics' but I'll explain how to solve this issue using pod 'Google/Analytics'
because the google official site recommends pod 'Google/Analytics'.
bridging header
You just need one line of code for google analytics.
#import <Google/Analytics.h>
Don't forget to set target-build setting for Objective-C-Bridging-Header.
You have to provide correct path to enable Objective-C-Bridging-Header.
Set Target-Build Setting-Objective-C-Bridging-Header
$(SRCROOT)/$(PRODUCT_NAME)/projectName_Bridging_Header.h
AppDelegate.swift
import Google
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?)
-> Bool { self.setupGoogleAnalytics()
..
self.setupGoogleAnalytics()
..
}
func setupGoogleAnalytics() {
// Configure tracker from GoogleService-Info.plist.
let configureError:NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
let gai = GAI.sharedInstance()
gai.trackUncaughtExceptions = true // report uncaught exceptions
gai.logger.logLevel = GAILogLevel.Verbose // remove before app release
}
SomeViewController.swift
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(true)
if let default_tracker = GAI.sharedInstance().defaultTracker {
#if DEBUG
print("default tracker")
#endif
}
// let tracker = GAI.sharedInstance().defaultTracker
let tracker = GAI.sharedInstance().trackerWithTrackingId("tracking_ID")
tracker.set(kGAIScreenName, value: screenName)
let builder = GAIDictionaryBuilder.createScreenView()
tracker.send(builder.build() as [NSObject : AnyObject])
}
Why do I use trackerWithTrackingId instead of defaultTracker property? You could got an error if you use defaultTracker :
fatal error: unexpectedly found nil while unwrapping an Optional value
defaultTracker property's initial value is nil, but it will be set after
trackerWithTrackingId method is called. But it doesn't work perfectly sometimes. To avoid this issue, I recommend that use trackerWithTrackingId method directly.
I make the sample project using pod 'GoogleAnalytics'. You can get an idea from it.
Good luck.
Test Env
GoogleAnalytics 3.14
Xcode 7.2.1
In Podfile
pod 'Google/Analytics'
In YourFantasticProjectName-Bridging-Header.h
#import "Google/Analytics.h"
You don't need this
GGLContext.sharedInstance().configureWithError(&configureError)
You need to have a proper tracker
let gai = GAI.sharedInstance()
let tracker = gai.tracker(withTrackingId: "UA-12345678-1")
In order for live view to work in GA dashboard, you must track screen using GAIDictionaryBuilder and correct key kGAIScreenName
tracker.set(kGAIScreenName, value: "this is my screen")
let event = GAIDictionaryBuilder.createScreenView()
tracker?.send(event!.build() as! [NSObject: Any])
In the same vein, to track events, you need to use GAIDictionaryBuilder as it will create dictionary with correct GA keys, and GA likes correct keys
let event = GAIDictionaryBuilder.createEvent(withCategory: "category", action: "action", label: "level", value: NSNumber(value: 120))
tracker?.send(event!.build() as! [NSObject: Any])
It seems to work in the simulator too
I faced the same problem. I could not import the "Google/Analytics.h" header as Xcode generate error. Because "Google/Analytics.h" header is not available in the 'GoogleAnalytics sdk' as mentioned in Google's Official page.
So, i just used following line
#import "GAI.h"
Hope it will work just fine.
Environment
Xcode: 8.2
iOS :10.2
For swift 3:
var configureError:NSError? = nil
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
let gai = GAI.sharedInstance()
gai?.trackUncaughtExceptions = true
gai?.logger.logLevel = GAILogLevel.verbose
I think it's better to send error to crashlytics, but continue executing an app:
func configureGoogleAnalytics() {
var configureError: NSError? = nil
GGLContext.sharedInstance().configureWithError(&configureError)
if configureError != nil {
Crashlytics.sharedInstance().recordError(configureError!)
}
}

I am matching guides for using AWSDynamoDB in a test project using Swift 2 in XCode 7.0 Beta. I am required to use that platform instead of the previous stable one and make it work.
I am using the next links:
https://docs.aws.amazon.com/mobile/sdkforios/developerguide/setup.html
http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/LoadData_Java.html
Best way to make Amazon AWS DynamoDB queries using Swift?
I already made it work for reading and writing text files and images to an S3 Bucket, but now that I am trying to use DynamoDB service something might be missing.
Here is my Podfile contents:
# Uncomment this line to define a global platform for your project
platform :ios, '8.3'
target 'AWSSDKTest' do
source 'https://github.com/CocoaPods/Specs.git'
pod 'AWSCore'
pod 'AWSAutoScaling'
pod 'AWSCloudWatch'
pod 'AWSDynamoDB'
pod 'AWSEC2'
pod 'AWSElasticLoadBalancing'
pod 'AWSKinesis'
pod 'AWSLambda'
pod 'AWSMachineLearning'
pod 'AWSMobileAnalytics'
pod 'AWSS3'
pod 'AWSSES'
pod 'AWSSimpleDB'
pod 'AWSSNS'
pod 'AWSSQS'
pod 'AWSCognito'
end
target 'AWSSDKTestTests' do
end
I had to delete Podfile.lock and Pods folder, deleted Configuration Sets in Project->Info->Configurations, and installed pods again.
Here is my bridging.h file:
#ifndef AWSSDKTest_bridging_h
#define AWSSDKTest_bridging_h
#endif
#import <AWSCore/AWSCore.h>
#import <AWSS3/AWSS3.h>
#import <AWSDynamoDB/AWSDynamoDB.h>
#import <AWSSQS/AWSSQS.h>
#import <AWSSNS/AWSSNS.h>
#import <AWSCognito/AWSCognito.h>
I downloaded the aws-ios-sdk-2.2.0.zip file, unzipped and added to Frameworks all the AWS frameworks.
I am trying to use AWSDynamoDBModel, here is a swift file for implementing the Upload Sample Items Example for using DynamoDB Mapper:
import Foundation
class Forum : AWSDynamoDBModel, AWSDynamoDBModeling {
var name : String = ""
var category : String = ""
var threads : Int = 0
var messages : Int = 0
var views : Int = 0
// override init!() { super.init() }
required init!(coder: NSCoder!) {
fatalError("init(coder:) has not been implemented")
}
class func dynamoDBTableName() -> String! {
return "Demo"
}
class func hashKeyAttribute() -> String! {
return "email"
}
class func rangeKeyAttribute() -> String! {
return "date"
}
/*
override init(dictionary dictionaryValue: [NSObject : AnyObject]!, error: NSErrorPointer) {
super.init(dictionary: dictionaryValue, error: error)
}
override func isEqual(anObject: AnyObject?) -> Bool {
return super.isEqual(anObject)
}
*/
}
I had to comment the lines that caused error because those might be fixed. The errors mentioned that those functions couldnt be overridden and that super.init couldnt be called inside a root method.
After cleaning and building again, the error is at the class declaration line
class Forum : AWSDynamoDBModel, AWSDynamoDBModeling {
The error says: Use of undeclared type 'AWSDynamoDBModel'
If I try writing other AWSDynamoDB classes they don't appear in the list of suggestions and then cause the same error.
Additionally I want to mention that in the developer's guide setup (first link above) the 4th point of the Getting Started with Swift section says: "Import the AWSCore header in the application delegate":
#import <AWSCore/AWSCore.h>
Than can't be done, only in the bridging.h file which is mentioned in the 2nd point.
My first request of assistance is in fixing the error mentioned and making the project recognize the AWSDynamoDB framework.
Then I request your help for any observation about this merge of different tutorials, also any other online tutorial or guide that is more clear than those mentioned.
In case you are using CocoaPods (0.36) with "use_frameworks!", this answer might solve your problem:
"Normally when you’re importing Objective-C code into Swift, you do so by including the header of the file containing that code in the “Bridging Header” for your project. And that is indeed how you include code from a static library (which your pods used to be.)
But it is not how your import Objective-C code from a Framework. To do that you simply type…
import Framework
…inside your Swift file that’s using the Objective-C class (where “Framework” is the name of the actual Framework containing the class.)"
Source here: http://rogueleaderr.com/post/115372471213/unresolved-identifier-in-swift-when-importing
I think the problem is not related to Xcode7Beta, but the installation process of your project. (My sample DynamoDB project runs fine under Xcode7Beta.)
If you installed the AWS Mobile SDK via cocoapods, you neither have to worry about the bridging file nor need to download aws-ios-sdk-2.2.0.zip file since cocoapods already did everything for you.
My suggestion would be:
clean your project, remove all aws related frameworks, bridging files that you manually added,delete Podfile.lock and Pods folder and AWSSDKTest.xcworkspace file, and the re integrate pods by running "pod install"
Open your project using Xcode 6.4, confirm it can be built and run successfully under Xcode 6.
If everything looks good via Xcode 6, reopen it via Xcode7Beta, If it failed to compile, please post the error output so I can take a look.
Thanks
I have set up a Swift iOS project with CocoaPods. I want to use pods based on both Swift and Objective C. Let's say I want to use KeychainAccess (Swift-based) and CocoaLumberjack (Objective C-based). Here's the Podfile I use:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!
pod 'KeychainAccess'
pod 'CocoaLumberjack'
Now, I try to use these pods:
import UIKit
import KeychainAccess
import CocoaLumberjack
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// this works fine
let keychain = Keychain(service: "access-token")
// this works as well
DDLog.addLogger(DDTTYLogger.sharedInstance())
// 'DDLog.Type' does not have a member named 'logLevel'
DDLog.logLevel = .Verbose
// 'DDLog.Type' does not have a member named 'logAsync'
DDLog.logAsync = false
}
}
Am I missing something? How do I make CocoaLumberjack work? (or any other ObjC pod, I assume I will have the same issue with other pods as well).
I have created a project which reproduces this issue.
