IOS crashes after login.

🐛 Bug Report

Whenever i press the login button i get redirected to the facebook page, fill in my data and get redirected to this screen:

At this point my app crashes and stops working. I have to rebuild the app on the simulator to get it working again. Then the facebook button tells me i'm logged in because it turned it to a logout button.

The error is:

To Reproduce

I do not know how to reproduce this error, can't find it anywhere either.

Expected Behavior

I expect it to login to facebook and return the data to me.

Code Example

I only use this code from the FBDK

<LoginButton readPermissions={['public_profile email']} onLoginFinished={ (error, result) => { if (error) { console.log(result.error); } else if (result.isCancelled) { console.log('login is cancelled.'); } else { AccessToken.getCurrentAccessToken().then( (data) => { console.log(data.accessToken.toString()); } ); } } } onLogoutFinished={() => console.log('logout.')} />

Did you fix this ?

[HarmJan1990]

Nope, can't seem to find the problem.

What iOS Facebook SDK are you using? I think I have similar problem using SDK 5.4
