Very strange issue.
It seems that a specific project of mine causes Xcode to crash while idle due to resources issue.
Not sure if related, but when viewing source code differences of this project, the entire window is flickering like crazy...
crash file is attached (converted to txt file otherwise can't attach it)
Any ideas?

I have an iOS app with the following configuration:
My own ObjC static library project - MyStaticLib
My own ObjC app target project - MyApp
I have both projects in the same Xcode workspace so that MyStaticLib is linked successfully to MyApp
Both projects have a mix of ObjC and Swift code successfully working.
Currently:
MyStaticLib: ObjC code can access Swift code and vice versa
MyApp: ObjC code can access Swift code and vice versa
ObjC code from MyApp can access ObjC code from MyStaticLib (This is achieved by adding Copy Files in Build Phases at MyStaticLib project settings with the ObjC header files)
Objective:
Swift code located in MyApp to access Swift code located in MyStaticLib
Issues:
If I'm trying to call a public Swift function located in MyStaticLib from MyApp, I get Cannot find 'YYY' in scope.
If I'm adding import MyStaticLib, I get dozens of Duplicate interface definition for class 'ZZZ'
Any idea how to resolve this?
Hi all,
Sharing a reproducible UIKit issue I’m seeing across multiple iPadOS 26 betas, with a tiny sample attached and a short video.
Short video

Tiny project
https://github.com/yoasha/ListSwipeOvershootReproSwift
Summary
In a UISplitViewController (.doubleColumn), a UICollectionView using list layout shows a large leading-swipe overshoot when the split view is expanded (isCollapsed == false). The cell content translates roughly 3–4× the action width.
Repros with appearance = .plain and .grouped
Does not repro with .insetGrouped
Independent of trailing provider (issue persists when trailing provider is nil)
Collapsed split (compact width) behaves correctly
Environment
Devices: iPad Air (3rd gen), iPadOS 26.0 (23A5326a) → Repro
Simulators: iPad Pro 11-inch (M4), iPadOS 26.0 beta 6 → Repro
Also tested on device: iPadOS 26 beta 5, 6, 7, 8
Xcode: 26.0 beta 6 (17A5305f)
Steps to reproduce
Launch the sample; ensure the split is expanded (isCollapsed == false).
In the secondary list, set Appearance = Plain (also repros with Grouped).
Perform a leading swipe (LTR: swipe right) on any row.
Actual: content shifts ~3–4× the action width (overshoot).
Expected: content translates exactly the action width.
Switch Appearance = InsetGrouped and repeat the leading (swipe right) gesture → correct (no overshoot).

If anyone from Apple needs additional traces or a sysdiagnose, I can attach promptly. Thanks!
// Secondary column VC (snippet)
var cfg = UICollectionLayoutListConfiguration(appearance: .plain) // also .grouped / .insetGrouped
cfg.showsSeparators = true
cfg.headerMode = .none

return s
}
// Trailing provider can be nil and the bug still repros for leading swipe:
cfg.trailingSwipeActionsConfigurationProvider = nil
let layout = UICollectionViewCompositionalLayout.list(using: cfg)
let collectionView = UICollectionView(frame: view.bounds, collectionViewLayout: layout)
// … standard data source with UICollectionViewListCell + UIListContentConfiguration
// Split setup (snippet)
