Piggybacking of @Santiago Jimenez Wilson's answer here.

Obviously patching react-native itself is pretty dirty so we took the suggested override and extracted it into a category.

Just create a new file called RCTHTTPRequestHandler+yourPatchName.m somewhere in your project:

//
//  RCTHTTPRequestHandler+yourPatchName
//

#import "RCTBridgeModule.h"
#import "RCTHTTPRequestHandler.h"

@implementation RCTHTTPRequestHandler(yourPatchName)

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler
{
  completionHandler(NSURLSessionAuthChallengeUseCredential, [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]);
}
@end

Next step would be to then differ between dev and prod and only overload the method for dev.
