How does Apple achieve this effect?
Hi everyone, I'm new to building apps on Swift and recently I've been wondering how does Apple get this blur effect behind the control center on Mac OS Tahoe. I think it would be nice to use in an app that I'm making but I can't seem to find it in the docs. Is it available through AppKit? I would appreciate some help on this

iOS 26 Liquid Glass - Without any Blur - Possible?
let glassView = UIVisualEffectView(effect: UIGlassEffect(style: .clear)) glassView.frame = CGRect(x: 100, y: 200, width: 200, height: 400) self.view.addSubview(glassView) Though UIGlassEffect has two variants: .regular and .clear, even the clear one has some blur on the background. Is there a way to do get absolute no blur? Edges still have the glass effect. Apple does this in two places: Camera app: Text magnifier:

Resize Window Form After Loading
I am trying to resize a Window Form after it loads and have done quite a bit of searching for code to do it. Here is one code snippet that works to size the form during the design phase. self.view.window?.contentMinSize = CGSize(width: 1100, height: 310) I have tried code like below to increase the window size after the Form loads if let myWindow = self.view.window ?? NSApplication.shared.mainWindow { // Increase window size and position after it loads let newRect = NSRect(x: 100, y: 100, width: 1400, height: 900) } It seems that this code not only changes the Form size after loading, but also changes the size of the Form in Main.swift, which is something I don't want. I read elsewhere that I had to disable constraints to resize the Form, so I tried code below. let tableView = NSTableView() tableView.translatesAutoresizingMaskIntoConstraints = false let newRect = NSRect(x: 100, y: 0, width: 1100, height: 600) myWindow?.setFrame(newRect, display: true) That code did not seem to do anything as well. Also, the Form displays in the lower left of the screen. Note that main reason I want to resize the Form after loading is to keep it smaller during design development. The same goes for the NSTableView, which I have not gotten to yet.

Correct way to handle 2 to 3 column switch
I'm using a NavigationSplitView on macOS which needs to show 2 or 3 columns depending on the selection of the sidebar. Column 1 has a list of main activities. Some of these just have some data to show and some have a sublist. Currently, when an item that has no sublist is selected, I set the 2nd column (content:) to: Spacer() .navigationSplitViewColumnWidth(0) This works, although it started hitting bugs requiring a workaround on macOS 26, which got me wondering, what is the correct approach here? NavigationSplitViewVisibility.doubleColumn is not the solution, as this hides column 1, not column 2.

Xcode 26 Beta 3 – SwiftUI Previews & Project Window State Broken After Minor Edits?
Hi everyone, since updating to Xcode 26 Beta 3, I’m seeing some really strange behavior. I just changed the color of a Color asset in my SwiftUI view – literally just switched from one named color to another – and suddenly: • Previews stopped working completely, with vague or no error messages. • Even when I changed the color back to what it was before, the previews still refused to build. • In addition, Xcode no longer restores the open tabs/windows when reopening the project. It just shows a blank editor every time I open it. This all happened without touching any project settings or code structure – just a simple color swap. Has anyone else run into this with Xcode 26 Beta 3? Would love to know if it’s a known bug or if there’s a workaround (besides nuking Derived Data, which I’ve already tried). Thanks!

Testing In-App Purchases
Hi, I have a couple of questions in regards to testing in-app purchases. I tested the subscription on a device but I'm not sure how to reset so I can test again. I didn't see the subscription in device settings or in Debug -> StoreKit -> Manage Subscriptions window. Additionally, I was wondering if there was a way to detect the subscription being made. I implemented this, but I'm not sure if that will work: .onChange(of: Product.SubscriptionInfo.RenewalState.subscribed) { if Product.SubscriptionInfo.RenewalState.subscribed == .subscribed { } }

Network access has changed
I had, a long time ago (over 10 years) developed an application that is connected to my UPS (for solar panels). Until yet it worked very well, and I didnot have to compute more than making updates of XCode. That was all. But yet I have swiched to the latest value of switch, and it continue to compile, but it does'not work. I am asking to yo in order keeping my app working as previously. As it does not work, which library is replacing Cloudkit.framework ? and which library is replacing InsPersistantContainer.framework ? Have a good day Guy Desbief

iOS 26.0.1: Different Liquid Glass Effects
Hello everyone, In the current iOS version, changes in the "liquid glass" light shining effects can repeatedly be observed on older iPhone devices (12/13/14). This change is often seen after the device is rebooted or after a SystemMemoryReset.ips (System Analysis Data). It changes very often... I'm not currently working on apps myself, but perhaps someone has ideas for the upcoming updates involving Liquid Glass. (please also check the screenshots)

Window Title Justification OS 26 Tahoe
I am working on a Mac App that was developed with Objective C and Interface Builder. In earlier versions of Mac OS the window title was centered. Now in Tahoe it's left-justified. Is there some way to set this? There is no setting for this in Interface Builder and I can't see any way to do it programmatically by reading the developer documentation. Is this even possible?

The airdrop was sent to the wrong device. Will modifying the interface in this way reduce the error
I have many Apple devices, such as macbook, iPad and iPhone. It's very convenient for me to transfer files between devices. However, when I want to send files to my own device in public places, I often click on the wrong recipient because the list avatar keeps changing. I hope the list of recipients can be grouped One group is my own device (or the one I often send to), and the other group is other devices. When the user is about to send, the mouse will be in a relatively fixed and mentally expected area. I feel that this can reduce the probability of sending wrongly

Suggestions on macOS and iPad app structure
Building an app to edit the various parameters of digital musical instruments. A typical user would have perhaps max 6 instruments, out of the hundreds of possibilities. Would like to structure the app with a global window, menu, etc which would be a free download. The user could download editor inserts for their particular set of instruments and ignore all of the others. The downloaded editors would show as options in a menu. It seem like more than a widget but less than a library. Building a monolithic app containing all possible editors doesn't seem like an option, but separate full-app editors for each piece of gear doesn't sound right either. Any suggestions out there? Thanks very much Brian

NFC Bottomsheet customization
Hi all, I wanted to check whether the NFC bottom-sheet UI shown by iOS during an NFC reading session can be customized. We have a Figma design (attached) for how the sheet should look, but we are not sure whether iOS allows modifying the default NFC UI. Is UI customization supported, or is the bottom sheet fully controlled by the system? Thanks in advance.

iOS 26 UI transparency causes readability and accessibility issues
This issue affects core system UI elements such as Control Center, notifications, and system apps. In iOS 26, the Liquid Glass UI introduces excessive transparency and blur across the system. This significantly reduces text readability, lowers contrast, and causes visual fatigue during prolonged use. There is currently no true option to fully disable Liquid Glass effects. Existing accessibility settings only partially mitigate the issue and do not restore a solid, high-contrast interface similar to iOS 18. Please consider adding a system-wide toggle to completely disable Liquid Glass and transparency effects, or provide a solid UI mode for users who prioritize readability and visual comfort. This is especially important for accessibility, as the current design negatively impacts users sensitive to eye strain and low contrast.

Icon looks broken on the App Store
Hi, I just had V1.0 of my app approved on the App Store and I immediately noticed that the icon preview is broken. It looks good in Xcode, on-device and also in the App Store link preview. The icon was built with Icon Composer. Here's the difference (left is App store): Has anyone encountered the same issue and found a solution?

Guideline 5.2.5 - Legal - Intellectual Property
Your app still contains features that mimic the iOS interface or behavior. I have a simple app that uses a NavigationSplitView 3 panels I have a section for Filters and User created Categories in Panel 1 A list of "Requests" from the selected Filters/Categories in Panel 2 and details of a request in Panel 3 It's designed to be simple and easy to use. How can it NOT "mimic the iOS interface" if I am using their own APIs? What should I do to get around this
