[BUG] Card reader selection UI is blocked on iOS 26 with sdk 6.2.0

[sstasi95]

Summary

On iOS 26 the card reader selection UI shown by calling SumUpSDK.presentCardReaderSettings (or even the old and deprecated presentCheckoutPreferences) is completely disabled, making it impossible to select a card reader or to start searching for available ones. There's a white overlay on the left side of the screen (see attached screenshot), which is probably blocking tap events from reaching the actual UI.

On iOS 18 it seems to work fine, but I only tested it on a simulator.

Steps to Reproduce

Calling SumUpSDK.presentCardReaderSettings on a device with iOS 26 should be enough.

Expected Behavior

UI should be enabled, and users should be able to interact with it.

Actual Behavior

UI is disabled, and users cannot interact with it.

iOS Version(s)

iOS 26

Impacted Devices

Tested on iPhone 15 Plus and iPad 9, but the issue should be visible on any iOS 26 device

• SumUp SDK: 6.2.0
• Swift: 6.2.1
• Xcode: 26.1.1

Thanks @sstasi95 for reporting this, we will take a look

@sstasi95 we're trying to reproduce this with iOS 26.1 but so far no luck. [edit: compiling with Xcode 26.1.1]

• Can you confirm that you see it when running the SumUp sample app that comes with the SDK?
• Can you also try the SumUp app from app store -- it has a similar card reader settings page under Profile-Settings (top right corner)
• Can you try debugging the view/window hierarchy using Xcode to see if there is a UIWindow overlaid on top or something else unexpected like that?

Thanks heaps
