When using a background color for a UINavigation controller it seems the header does not extend to the top of the device for iPhone Duo when its closed in portrait mode. See screenshot. It should fill the entire 'status' bar up to top of device, Landscape correctly works, its just Portrait. Any thoughts on if this is 'expected' behavior? Seems odd to not just extend the navbar alll the way to the top.

Hey All! Curious if others are seeing this where UIAlertController style action sheets (and to some extent Alert type) in iPad OS 27.0 B1 seem to be very buggy. By that i mean if you have an action sheet that has 20 items or some, half of them are not visible until you scroll or move the mouse over them (in simulator), and when tapping on them its a hit or miss if it triggers the delegate, sometimes it triggers on the first tap (click) or sometimes it takes 2 to 3 taps (clicks) to the delegate to trigger and the actioinsheet to dismiss. On initial look it seems iOS 27.0 B1 is working just fine, seems iPad Specific. While the list of the items not showing is only for action sheets, the 'sometimes' takes 2 to 3 taps (clicks) to select and item happens in both type ActionSheet and Alert. Sometimes it takes 2 to 3 taps to tigger an alert button etc. Both the above described issues happen on both device and simulator. Ive attached a video and a sample Proj to FB22998239. Hoping one of the UIKit Engineers can take a look, thanks for everything!

Hey all in iOS26.1 i seem to be getting a bunch of Constraint errors when setting the rightBarButtonItem leftBarButtonItem. Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) ( "<NSAutoresizingMaskLayoutConstraint:0x6000021a2a30 h=--& v=--& _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x13d84c080.width == 0 (active)>", "<NSLayoutConstraint:0x6000021a1cc0 _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x13d84c080.leading == _UIButtonBarButton:0x106cd3ed0.leading (active)>", "<NSLayoutConstraint:0x6000021a1d10 H:[_UIButtonBarButton:0x106cd3ed0]-(0)-| (active, names: '|':_TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x13d84c080 )>", "<NSLayoutConstraint:0x6000021a19f0 'IB_Leading_Leading' H:|-(2)-[_UIModernBarButton:0x106cc80b0] (active, names: '|':_UIButtonBarButton:0x106cd3ed0 )>", "<NSLayoutConstraint:0x6000021a1a40 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x106cc80b0]-(2)-| (active, names: '|':_UIButtonBarButton:0x106cd3ed0 )>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x6000021a1a40 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x106cc80b0]-(2)-| (active, names: '|':_UIButtonBarButton:0x106cd3ed0 )> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful. Curious if im setting something wrong, or maybe i can just ignore these (granted they are annoying in my logs) This wasnt happening in iOS 26.0

Hey All, Curious if you guys are seeing the same thing for those who are using Interface Builder Files (Xib) i set the line seperator to none and on my app (built against ios 18 on the app store, but doesnt matter if i build it against ios 26, or ios 26.1) when running on iOS 26.1 the line seperator will show even when i set it to None. Funny enough if i just play around with the XIB file and set it to single line and maybe RED color the IB file will show it but when running it its the same old default dark greyish color. BUT if i set the line seperator in CODE either to be none or with single line + red it looks good when running on sim / device. So it seems to be an issue with XIB files not being respected in iOS 26.1 (only) i have submitted a feed back FB20466783, hope this helps any xcode devs / uikit devs. thank you !

Hey all when building my app on xcode 26 beta 3 im getting a new warning about a [APPNAME]-primary-bridging-header.pch no file or directory found, this warning is new to beta 3 for me, obviously if i turn precompile headers off in build settings the warning goes away so there is a work around, but figured ide let the xcode engineers know ! (maybe its just me, but i wouldnt think so) Again this is just a warning and not stopping the build but wanted to see if this is a new warning anyone else is getting. Thanks ! FB18710327 Ps - ive tried the usuals .. clean build, delete derived data get same warning :)

Hey all wondering if anyone has seen this new in xcode 26 beta 2 it seems any NIBS with a UISwitch will 'error' saying please submit a feed back and attach the log, i did submite a feedback but looking at the log it simply says : the tool closed the connection (IBAgent-iOS) then if you just build again it builds fine and runs fine, but if you switch from simulator to device and build the error will happen again, but same thing build again and it works. I opened my NIBS with the switch and they open just fine, no errors or anything so im wondering if its something in the build system. For any xcode engineers here: here is my feedback number 18348463

hey all today for some reason im getting Unsupported SDK or Xcode version valdation failure when uploading to app store connect. I haven't changed anything and i was able to upload jsut a few days ago with same version of xcode. Its xcode 16.0 anyone else getting this? Maybe its a server side issue?

Trying to download the latest's SDKS (iOS and WatchOS) DVTDownloadableErrorDomain Code:41 Has anyone been able to download the new sdk's for xcode?

when presenting an uialertviewcontroller either an actionsheet or alert it seems to have some weird interaction with my tableview cells. For example, i have custom font sizes a user can set so when im loading my cell i set the font size. It looks good on load but the second i preset a uialertviewcontroller it 'reset's all the cells to the default interface builder set fontsize. Some cells i use attributed text programmatically and that all gets reset as well to 'default' interface builder label settings. Its very odd. this is in iOS 18 b1. Funny enough it seems like every beta 1 (if i recall maybe in iOS 17 or iOS 16) it did the same thing there attributed text would like 'reset' its very odd. I have a hunch this is a bug and filed a feedback, but curious if there are any workarounds, or simply just wait until its fixed :D . Thanks all !

Is anyone having 'oddness' with ios 17.4 b1 either not calling delegate - (UIInterfaceOrientationMask)supportedInterfaceOrientations or simply ignoring it. For example apps that are locked in portrait (but do have to support rotation at different parts of the app) seem to be freely be able to rotate even on places it shoudnt. Im freely allowed to rotate the youtube app for example in landscape, at the main screen, not just on the video player. Im seeing this in other apps to that are locked portrait. But if you kill the app, and restart the app then it will not rotate. something funky was changed or a bug. ive never seen this before in ios 17.0 - 17.3

there seems to be an issue with transparency in the simulator present in beta 5, didnt see this in the other betas, anyone else having this issue? im on a Intel Mac.

Anyone else trying to download the watchos b4 sdk, maybe its not uploaded yet? cannot build without it :( Failed with HTTP status 403: forbidden Domain: DataGatheringNSURLSessionDelegate Code: 1 User Info: { DVTErrorCreationDateKey = "2023-07-25 18:59:29 +0000"; } System Information

Im thinking maybe there was a internal flag not removed or something. Not only do i have the version number on the icon (which is new to me, and i kinda like it). But within XCode it says Apple Internal. is it just me?.

Im not sure if its just my comp (2019 iMac 16gb of ram) but opening the simulator takes about 10 min, then to just open an app on the simulator takes about 6 min, im curious if its just me, but this is crazy.

Entry Point (_main) undefined for architecture x86_64, Anyone else getting this after updating settings request by xcode 14 and your watch app?
