Seeing the same behavior. Not sure what's going on, but I was able to work around it by making the reuse identifier the same as the nib name. E.g.: class ListItem: NSCollectionViewItem {     static let reuseIdentifier = NSUserInterfaceItemIdentifier("ListItem") // was "list-item-reuse-identifier" ... I suspect I'm now picking up some fallback behavior. -Steve

Multi-page layout not supported in TextKit2. See the discussion here: https://developer.apple.com/forums/thread/682251 At WWDC, a frameworks engineer indicated they were looking into it, but there has been no update and the requested Feedback (FB9285387) is still open (Nov 4th) with no recent similar reports. Please file a dupe of FB9285387 if this is important to you. -Steve

My radar is currently open with less than 10 similar reports. If you haven't done so, could you file a dupe? There is also a Twitter discussion of this in case it helps. In my app, I work around the missing functionality with a one-off vc that creates a menu-like table view.

The b7 release notes give another workaround: In Xcode select Product > Scheme > Edit Scheme…, then deselect Run > Options > Queue Debugging > “Enable backtrace recording.” Works for me. -Steve

Workaround: Run the Simulator on an Intel Mac.

Seeing this too, even on WWDC sample code. Running on macOS 11.5.1 on an M1 mac.

Same crash here. 11.5.1 on an M1 Mac. Xcode b3, b4, and b5.

For those keys, you probably need to set wantsPriorityOverSystemBehavior to YES.

This regression is present in 13.0 beta 3 (13A5192j) as well.

Seeing the same thing on macOS 11, most recently with Xcode 12.2 rc: restoreCompletedTransactions finishes with no transactions. Other functions work fine. Steve

Same here. macOS 11 beta 10, Xcode 12.2 beta 3. Xcode purchases complete and are visible in Debug > StoreKit > Manage Transactions, but the receipt is never updated. Calls to [[SKReceiptRefreshRequest alloc] initWithReceiptProperties:nil] result in an Apple ID login request. I do notice the following in system.log: Oct 15 17:30:32 Steves-MacBook-Pro appstoreagent[814]: objc[814]: Class asn1ReceiptToken is implemented in both /System/Library/PrivateFrameworks/CommerceKit.framework/Versions/A/Frameworks/CommerceCore.framework/Versions/A/CommerceCore (0x7fff88733ef0) and /System/Library/PrivateFrameworks/CoreFP.framework/Versions/A/CoreFP (0x10b7cfd90). One of the two will be used. Which one is undefined.
