Crash on AWSMobileClient when initialising at runtime.

State your question

We are currently initialising AWPinpoint dynamically (i.e. without the use of JSON files). We do this, because the configuration is dependant on a few conditions that are only available at a later point. We do the following:

let localConfiguration = AWSConfiguration.configuration

let credentialsProvider = AWSCognitoCredentialsProvider(regionType: localConfiguration.cognitoPoolRegion.toAWSRegionType,
                                                                identityPoolId: localConfiguration.cognitoPoolId)

let configuration = AWSServiceConfiguration(region: localConfiguration.pinpointRegion.toAWSRegionType,
                                                    credentialsProvider: credentialsProvider)

AWSServiceManager.default().defaultServiceConfiguration = configuration
pinpointConfiguration = AWSPinpointConfiguration(appId: localConfiguration.pinpointAppId, launchOptions: launchOptions)

/// later on:
pinpoint = configuration.pinpoint /// AWSPinpoint
pinpointAnalyticsClient = configuration.analyticsClient /// AWSPinpointAnalyticsClient

My AWSConfiguration has the following shape:

struct AWSConfiguration {
    let cognitoPoolId: String
    let cognitoPoolRegion: String
    let pinpointAppId: String
    let pinpointRegion: String
}

At a later point, we call this:

AWSMobileClient.default().interceptApplication(application, didFinishLaunchingWithOptions: options)

The above call works fine in DEBUG mode, but it's crashing in RELEASE with the following:

Thread 1: "The service configuration is `nil`. You need to configure `awsconfiguration.json` or `Info.plist` before using this method."

This is how our awsconfiguration.json looked (before removing it):

{
  "UserAgent": "MobileHub/1.0",
  "Version": "1.0",
  "CredentialsProvider": {
    "CognitoIdentity": {
      "Default": {
        "PoolId": "eu-west-xyz",
        "Region": "eu-west-1"
      }
    }
  },
  "IdentityManager": {
    "Default": {}
  },
  "PinpointAnalytics": {
    "Default": {
      "AppId": "pyx",
      "Region": "us-east-1"
    }
  },
  "PinpointTargeting": {
    "Default": {
      "Region": "us-east-1"
    }
  }
}

Question:

1. Is there something special happening in Release?
2. Do I even need to call AWSMobileClient.default().interceptApplication? We only use AWSPinpoint.

Which AWS Services are you utilizing?

I am using AWSPinpoint.
