There appears to be a serious issue in iOS 26.4 regarding text alignment. All text strings are rendered right-aligned instead of left-aligned, even when explicitly setting the paragraph style to NSTextAlignmentLeft. This behavior is unexpected and seems to indicate a regression in text rendering. Could you please confirm whether this is a known issue in iOS 26.4? I am using the following code in a central function that has been working reliably for years across all my apps. Best regards, Rolf Code: NSMutableParagraphStyle* paragraphLeft = [[NSMutableParagraphStyle alloc] init]; if (paragraphLeft != nil) { paragraphLeft.alignment = NSTextAlignmentLeft; NSDictionary *settings = @{ NSFontAttributeName : font, NSForegroundColorAttributeName : fontclr, NSParagraphStyleAttributeName : paragraphLeft }; [theString drawAtPoint:CGPointMake(x, y - font.ascender) withAttributes:settings]; [paragraphLeft release]; }

I’m using MFMailComposeViewController to send emails from my app. Since updating to iPadOS 26.4, there is no way to cancel the mail composer because the “X” button in the top-left corner has disappeared. On iPhone with iOS 26.4, everything still seems to work as expected. Is this a known issue, or am I missing something? Has anyone else experienced this, or found a workaround?

In an objective C app I'm now using (in every view controller): (void) traitCollectionDidChange: (UITraitCollection *) previousTraitCollection { ..... } to handle dark mode changes. This is all very easy to implement. traitCollectionDidChange is deprecated in iOS 17. In the documentation there is no objective C example on how to work with the new iOS17 registerForTraitChanges function. Hard to figure out how to do this. Am not familiar with Swift, so the wwdc video could not help me. Where can I find some objective C examples? Best regards/Rolf Netherlands

I’m seeing that in the windowed-apps multitasking mode, the new window controls (the three “traffic-light” icons) can overlap the top-left corner of my app’s main view. Detection: How can I programmatically determine whether these window controls will be displayed? Geometry: If they are displayed, how can I find out their exact position and size? I’d like to adjust my layout at runtime to ensure no content is hidden beneath those controls. For reference, my main view does not include a status bar or navigation bar at the top.

In iPadOS 26, the Control Center includes a Multitasking button that lets users switch between full-screen and windowed apps. Is any UISceneDelegate method invoked when this happens, or is there another mechanism by which the app is notified?
