Hi,
I am using SDK SQVersion - 2.3.0
For testing using SQMPMockReaderUI. Now click on it
app crashes on iOS 26 with
*** Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘You must provide a value (key=filters.glassBackground.inputBleedColorMatrixFillColor)’
but its working fine on iOS 18.

Did you add a visual effect parameter during a UI animation. 
Hi Bryan,
Is this something new for ios 26? Can you provide sample?
Hi Bryan,
Here is the code I am using to present
if (_mockReaderUI.isPresented == false)
{
NSLog(@"Mock reader not presented. Calling present");
[_mockReaderUI presentAndReturnError:&error];
if (error != nil)
{
NSLog(@"Present Failed with error: %@", error);
}
else
[self payViaSqaureReaderForAmount:100];
}
else
{
NSLog(@"Mock reader already being presented");
}
Can you please explain a little bit further? This works fine in iOS 18, but there is an issue in iOS 26.
What is the full crash log your getting when this happens?

CoreSimulator 1048 - Device: iPad Pro 13-inch (M4) (83EBBACD-AFC7-4DF9-9CE6-73DEF018C388) - Runtime: iOS 26.0 (23A343) - DeviceType: iPad Pro 13-inch (M4)
Looks like this is missing a required color matrix parameter:
filters.glassBackground.inputBleedColorMatrixFillColorIs it missing for the SDK? Or for my app?
