Firebase/Core Problems

[perexlautaro]

Expected Behavior

Work and compile in ios like in android.

Actual Behavior

• Adding the plugin: ionic cordova plugin add cordova-plugin-firestore --save --variable ANDROID_FIREBASE_CORE_VERSION=+ --variable ANDROID_FIREBASE_FIRESTORE_VERSION=17.1.0
• Compile: ionic cordova build ios
• Then open .xcworkspace in xcode and run in real device, I get the following error:

Undefined symbols for architecture arm64:

• To fix this error, I add two pods:
  • FirebaseMessaging
  • FirebaseRemoteConfig

Resulting in:

platform :ios, '10.0'
use_frameworks!
target 'XXX' do
        pod 'FBAudienceNetwork', '4.28.1'
        pod 'GoogleMobileAdsMediationFacebook', '4.28.1.1'
        pod 'Firebase/Firestore'
        pod 'GoogleMaps', '~> 2.7.0'
        pod 'SwiftyRSA', '~>  1.5.0'
        pod 'CryptoSwift', '~> 0.13.0'
        pod 'FirebaseMessaging'
        pod 'FirebaseRemoteConfig'
end

• Then: pod install

• After that, the app compile, but I get an error in Runtime:

Steps to Reproduce the Problem

$ ionic start testApp blank
$ cd testApp/
$ ionic cordova plugin add cordova-plugin-firestore --save --variable ANDROID_FIREBASE_CORE_VERSION=+ --variable ANDROID_FIREBASE_FIRESTORE_VERSION=17.1.0
$ ionic cordova build ios

Open platforms/ios/MyApp.xcworkspace in xcode and run

As you have got as far as compiling and it is falling over at runtime, do you have some example code?

[perexlautaro]

Yes, I created a repo that contains an example app that gets the same error at runtime: Ionic-Firestore-App

[perexlautaro]

I could fix this error:

2019-01-15 12:03:09.150246-0300 XXX[1263:341484] 5.15.0 - [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add `[FIRApp configure];` (`FirebaseApp.configure()` in Swift) to your application initialization. Read more: https://goo.gl/ctyzm8.

The solution was remove this block:

if(![FIRApp defaultApp]) {
    [FIRApp configure];
}

And add:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"GoogleService-Info" ofType:@"plist"];
// if file is successfully found, use it
if(filePath){
    NSLog(@"GoogleService-Info.plist found, setup: [FIRApp configureWithOptions]");
    // create firebase configure options passing .plist as content
    FIROptions *options = [[FIROptions alloc] initWithContentsOfFile:filePath];   
    // configure FIRApp with options
    [FIRApp configureWithOptions:options];
}
// no .plist found, try default App
if (![FIRApp defaultApp] && !filePath) {
    NSLog(@"GoogleService-Info.plist NOT FOUND, setup: [FIRApp defaultApp]");
    [FIRApp configure];
}

The solution is related to this comment

Trying a little more I found that line: [FIRApp configureWithOptions:options]; (before [FIRApp configure];) crash the app

[perexlautaro]

Any update on this?

[ReallySmallSoftware]

Sorry, I will try and take a look in the next few days, although I would expect the GoogleService-Info.plist to always be present. Is there a reason why it isn't?

[perexlautaro]

No, there is no reason. The GoogleService-Info.plist is always present.
Don't worry, when you can. Thanks for answering!
