Firebase – Ravi Shankar

Firebase enables apps with Phone Authentication feature but when testing your app you might have received the following error.

We have blocked all requests from this device due to unusual activity. Try again later.

This user usually occurs when you have received too many OTP’s within a short period of time. And we have to wait for an hour to start using the Phone Authentication feature again.

Recently Firebase has added a feature to add test numbers. This can be found under Firebase Console -> Authentication -> Sign-in method -> Phone

PhoneAuthentication

Now you can use “Phone numbers for testing” section to add test phone numbers. The test numbers will not be blocked and will not affect your testing. I believe you can also use the test numbers for Apple Approval process when publishing your app.

If you are using Firebase Crasyltics in your app and if bitcode is enabled then you might see this message

“Upload missing dSYMs to see crashes” when trying to view reported crash in Firebase Crashlytics. In order the see the stack trace, you can try uploading the dSYMs files.

Compress .dSYMs files.

Launch Xcode Organizer.
Select the App on the Right hand side and navigate to the version which caused the crash.
Right click on the version and select Show in Finder.

Right click the archive file and select “Show Package Contents”.
Copy all the dSYMs files to another location.
Compress the file and upload the compress file to Firebase to see see the stack trace.

iTunesConnect

Another option is to download dSYMs files from iTunes Connect.

Select your App -> Activity section -> Select the Version -> Download dSYSM
