Check if app is on TestFlight/Google Play Beta

This is a feature request, please let me know whether it’s valid for the project or not.

Description

A simply function that returns true if the app has been downloaded through TestFlight or Google Play Beta, e.g. isTesting().

The use-case is that I want to print out errors on screen if it’s on TestFlight and Build Configuration === 'Release' but not on production (downloaded from store).

For those searching for a solution, here is the solution for iOS TestFlight. I am unaware of any google play solution.

In your Xcode workspace, create a file ProdChecker.h

#ifndef prodChecker_h
#define prodChecker_h

#import <React/RCTBridgeModule.h>

@interface ProdChecker : NSObject <RCTBridgeModule>
@end

#endif /* prodChecker_h */

In your Xcode workspace, create a file ProdChecker.m

#import "ProdChecker.h"

@implementation ProdChecker

RCT_EXPORT_MODULE();

RCT_REMAP_METHOD(isTestflight, resolver: (RCTPromiseResolveBlock)resolve
                 rejecter:(RCTPromiseRejectBlock)reject)
{
  NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
  NSString *receiptURLString = [receiptURL path];
  BOOL isRunningTestFlightBeta =  ([receiptURLString rangeOfString:@"sandboxReceipt"].location != NSNotFound);
  if(isRunningTestFlightBeta) {
    NSString *thingToReturn = @"TESTFLIGHT";
    resolve(thingToReturn);
  } else {
    NSString *thingToReturn = @"PRODUCTION";
    resolve(thingToReturn);
  }
}

@end

Those are the files needed to call the objective-c functions from react native. The function above will determine if the app is on the App Store or on TestFlight.

And now the react-native implementation:

import { NativeModules } from 'react-native';
const ProdChecker = NativeModules.ProdChecker;

ProdChecker.isTestflight().then(val => {
    if(val != "TESTFLIGHT") {
        // app is in production on App Store, not TestFlight
        // execute all production specific code here 
    }
})

This way, you’ll be able to tell if the app is in production or not.

I expect that 1 year old issue will be brought to your attention 😃 which could be annoying but that’s the best I could do now. If I could do a PR I would do it in a first place 😃 unfortunately, I don’t know the right solution, especially for Google Play.
