This issue is causing issue in login.

I haven't seen this issue before, so if you have some other information available (e.g. from Crashlytics) that would be really helpful:

1. How many (percentage) of users are being affected?
2. Do you have any information about which iOS version, an/or which device models (e.g. 6s, 7, X) are being affected/are crashing?
3. Or other means/steps for recreating the issue?
4. Which version of the iOS SDK are you using in the app?

@jorunfa

1. How many (percentage) of users are being affected? we have received 300+ complaints of login today
2. Do you have any information about which iOS version, an/or which device models (e.g. 6s, 7, X) are being affected/are crashing? iOS version 11
3. Or other means/steps for recreating the issue? Our current use case is LOA 1. I am collecting more information on this from vendor
4. Which version of the iOS SDK are you using in the app? iOS SDK 1.4.4

We are testing latest release 1.4.6

[jorunfa]

If I remember correctly 1.4.4 crashes on iPads and other older 32 bit devices, see #48. This should be resolved by updating to 1.4.5 or 1.4.6. https://github.com/telenordigital/connect-ios-sdk/releases

[nabeeljaved]

@jorunfa We have created new builds with latest SDKs. I will update after testing

Did it work? I'll reopen this issue if it didn't.
