React-native-app-auth: Exception '<AppDelegate: 0x600001ce4120> does not conform to RNAppAuthAuthorizationFlowManager' was thrown while invoking authorize on target RNAppAuth with params. (. IOS )

[npaul2173]

Issue

So i am using react-native-app-auth. version 4.4.0
While calling authorize() method i get a error only for IOS, not for android

STEPS I TOOK
1) Got config * and save it to state
2) Pass as parameter for authorize( this.state.configauth )

Config Structure looks like this
{

   "issuer”:”Link”,
   "clientId”:”I”d,
   "redirectUrl”:”Link”,
   "additionalParameters":{

      "nonce":"PauKyLe3456bhMgv/OJT7WSx6Q9RiBc/D3zDt4hxsHrkIMMDst0546bsg890dfsgaVVJVOjEniDP7h4e2uOokHUHMIwgk="
   },
   "scopes":[

      "openid",
      "d4a48c9efghfg-429b-9ab5-a4e2e2126079",
      "offline_access"
   ],
   "serviceConfiguration":{

      "authorizationEndpoint":"Link",
      "tokenEndpoint":"Link",
      "revocationEndpoint":"Link
   }
}

bump! Hi Devs. This issue could really use some love and attention. It has me completely blocked. I've already missed one deadline because of it. Help is appreciated.

To get around it, I commented out the following code in node_modules/react-native-app-auth/ios/RNAppAuth.m which throws the error.

  if (![[appDelegate class] conformsToProtocol:@protocol(RNAppAuthAuthorizationFlowManager)]) {
        [NSException raise:@"RNAppAuth Missing protocol conformance"
                  format:@"%@ does not conform to RNAppAuthAuthorizationFlowManager", appDelegate];
 }

Dependencies:

"react": "~16.9.0",
    "react-dom": "~16.9.0",
    "react-native": "~0.61.5",
    "react-native-app-auth": "^5.1.1",

Does it fix the issue, or just kick it down the road to be someone else’s problem?

I was having similar issue, but later I realize that I did not update AppDelegate.h as per documentation. Once I update AppDelegate.h that error is gone.

[mjstelly]

@saachitech what does that mean? Which AppDelegate? How did you update it? Your comment needs more detail, please.

[saachitech]

@mjstelly You can find AppDelegate.h in ios/[whatever_your_project_name] directory. You can open this file in xcode and update it according to the docs link I commented in my last comment. Hope this helps!

[mjstelly]

@saachitech That did the trick. I'm in your debt. Thanks!

hi with me this code didn't work, my react is 0.62.2 the app goes and closes

[wilkhp29]

correct instead of using the documentation import uses this the rest can follow normal

#import <react-native-app-auth / RNAppAuthAuthorizationFlowManager.h>

this comment explains the correct fix for this.

thanks @saachitech 🤗
