Open Radar 27660401: Remove or raise memory limit for Packet Tunnel Provider extension

iOS 15 limit increase

As of iOS 15 the limit has been raised to 50MB. This is much more manageable and probably sufficient.

I'm going to close this issue (if I can figure out how).

Open Radar FB8914231: [Chrome] arm64: Writing a Mach-O executable via mmap produces something that incorrectly fails code signature verification and won’t run

2020-12-17 from Apple

Engineering has provided the following information regarding this issue:

This is most likely due to the fact that the executable's pages have been created via an mmap() mapping, so they're marked as "wpmapped". Since we can't always easily determine if all the writable mappings are gone, a page marked as "wpmapped", i.e. a page that has been mapped for write access in the past, is considered as tainted, so it will fail code-signing verification even if it matches its signature. That's because if there's still a writable mapping somewhere, that mapping could taint the page at any time, including after we validate its signature and start executing from it.

We could potentially try and mitigate this by resetting the page's "wpmapped" when we're absolutely sure that it's safe to do so but that might not cover all the cases and could possibly open some security holes.

The work-around is to use write() instead of mmap() to create/copy the file.

Open Radar FB7977764: Visual bug when setting UITableViewCell contentConfiguration when swipe to delete button is showing


Still buggy in 12 beta 4 / iOS 14 beta 4:

Open project in Xcode 12 beta 4 Launch app in iPhone SE (2nd generation simulator) (might have to tap back to get back to Master) Make there be 2 rows on the table. Swipe the first row. Swipe the second row and immediately after the swipe tap the reload button.

What expect to happen. Row 1 should have animated away

What happens. Row 1 animates back out as if it was swiped and then animates away. (see attached video Screen Recording 2020-08-17 at

Open Radar FB8969539: Xcode is unable to Archive a project with Preview Content

I had a very similar issue occur, only I was building an App Clip for an existing app. I wasn't able to compile with the release scheme nor archive for distribution.

The solution was to include the Preview Content directory under the development assets of the parent app's target, not the App Clip target itself. That way, I got it to work in all cases such as SwiftUI previews, release builds, and archiving.

If you close the home screen after a short time the MFI Accessory disconnects. We need to process the data in the background. So this is a serious bug.

Open Radar 46944818: UICollectionView.contentSize is wrong with self-sizing cells and non-default minimumLineSpacing

The actual bug

Thanks a lot an00na for your bug report in the first place, it oriented me toward the proper solution. As of iOS 15, the bug is still present (and it was already present on iOS 11).

However, the actual bug is that: - the layout uses minimumLineSpacing for displaying - but it uses minimumInteritemSpacing for computing the contentSize.

The solution is therefore to set both to the same value. It explains why you were misled thinking it only works when minimumLineSpacing is 10: that is the default value of minimumInteritemSpacing.

Open Radar FB9726200: False error. "module name "foo" is not a valid identifier"

Root cause found

In a Swift project with only one main.swift file, Xcode disregards the provided PRODUCT_MODULE_NAME in the Xcode project settings and uses -module-name main.
