Could you try with the latest version of the Mobile SDK (12.0.1)? A number of bugs were addressed in that area.

@wmathurin : Thanks wmathurin. i will try it out. Meanwhile could you please share some other bugs id related to this context. Also, is that confirmed the bug has been fixed in V12.0 anywhere in SDK or anybody confirmed this bug has been resolved in V12.0. Please share your response..that would be grateful.

We have not seen your bug so I don't know for sure whether it was addressed but since we don't patch old versions of the SDK, we first need to confirm it is still happening in 12.0 before investigating further.

@wmathurin - From the Crash Log we identified, our app's last Salesforce SDK version is 9.1.0. In the latest release of our app we used Salesforce SDK version 11.1.0.

Below is the block of code_(SFSDKSalesforceSDKUpgradeManager class inside + (void)upgrade method)_ getting crashed when attempting to check accessibilityAttribute from SFSDKKeychainHelper.

From your end, any assumptions/idea why the main thread hold for a while, would be welcome.

`
if (!lastVersion || [lastVersion compare:@"9.2.1" options:NSNumericSearch] == NSOrderedAscending) {
// 9.2.0 & 9.2.1 upgrade steps both need file and keychain access, if we don't have those,
// abort the upgrade so that it can rerun

        **if (![SFSDKKeychainHelper accessibilityAttribute]) {**
            // Only update accessible attribute if the app isn't setting it
            [SFLogger log:[self class] level:SFLogLevelError format:@"Attempt keychain attribute update"];
            SFSDKKeychainResult *result = [SFSDKKeychainHelper setAccessibleAttribute:KeychainItemAccessibilityAfterFirstUnlockThisDeviceOnly];
            if (result.status == errSecInteractionNotAllowed) {
                [SFLogger log:[self class] level:SFLogLevelError format:@"Upgrade step skipped because keychain access not allowed"];
                return;
            }
        }
        
        NSArray<NSString *> *filesWithCompleteProtection = [SFSDKSalesforceSDKUpgradeManager filesWithCompleteProtection];
        if ([filesWithCompleteProtection count] > 0) {
            if (![SFApplicationHelper sharedApplication].isProtectedDataAvailable) {
                [SFLogger log:[self class] level:SFLogLevelError format:@"Upgrade step skipped because files have complete protection and protected data isn't available"];
                return;
            }
            [SFSDKSalesforceSDKUpgradeManager updateDefaultProtection:filesWithCompleteProtection];
        }
    }
