Apple hat vorgestern Nacht die sechste öffentliche Beta von iOS 11 für Entwickler freigegeben. Es ist das nächste große Release des mobilen Betriebssystems.
Seit zehn Wochen können sich alle Interessenten am Apple Beta Programm anmelden und das neueste große Release für iPhone, iPad und iPod Touch testen. iOS 11 ist vollgestopft mit Neuerungen. Während natürlich auch das iPhone viel davon haben wird, wird iOS 11 explizit das iPad nach vorne bringen. Multitasking wurde mit einem einblendbaren App-Dock neu überdacht und eine App für Dateien - ähnlich dem Finder auf Macs - soll den Austausch von Dateien erleichtern. Der App Store wurde überarbeitet und sieht jetzt aus wie Apple Music. Neben neuen Features für Benachrichtigungen, Karten und unterbrechungsfreiem Autofahren, sind die sichtbarsten Änderungen wohl das neue, selbst konfigurierbare Kontrollzentrum und AirPlay 2, dass aus kompatiblen Lautsprechern ein Multi-Room-System macht. Apple TV kann dabei als Steuerzentrale verwendet werden.
Hier die Änderungen der Beta 6 von iOS 11 im Detail:

UINavigationItem.searchController now works with view controllers that use a UIScrollView. (32511772)Known Issues
UIDocumentBrowserViewController does not show UIDocumentPickerExtensionViewController app extensions in the list of sources. While these will be re enabled in a future beta, consider using an NSFileProviderExtension instead, as they are integrated in UIDocumentBrowserViewController instead of being presented in a separate sheet. (31975976)
SettingthetextContentTypetousernameorpasswordforUITextFieldinthe previewProvider property of UIDragItem is not fully implemented. During the drag session, each change to the previewProvider causes an immediate update, regardless of which app changed it.

SettingthepreviewProviderpropertyofUIDragItemimmediatelyafterthedrag item is created has no effect. (32284908)
Workarounds:
Copyright © 2017 Apple Inc. All Rights Reserved.Page 18 of 22
Implement dragInteraction:previewForLiftingItem:session: in your drag interaction's delegate to change the lift preview. The preview carries over to the drag session.Change the preview during the drag session by setting previewProvider after the delegate’s sessionWillBegin is called. If you are using UITableView or UICollectionView, there is no direct equivalent of that method, so you may use a delay instead.
ThecanLoadObjectsOfClasses:methodofUIDragDropSessionwillberemoved in a later seed. Use canLoadObjectOfClass: instead. (32242367)
When dragging more than five items, the drop/cancel animation uses a default animation. The system calls the dropping/canceling preview calls for the first five of these items, even though they are not used. In a later beta, the system will not make these calls, and instead provides an additional API for animating alongside items for which a custom animation cannot be applied. (32299785)

Table views in Interface Builder documents compiled with Xcode 9.0 may have fixed heights for rows, section headers, and section footers, and may not self-size by default. (32188814)Workaround: Set the table view rowHeight, sectionHeaderHeight, or sectionFooterHeight to UITableViewAutomaticDimension after the table view has been instantiated.
UITableView has a new system gesture for quickly selecting rows. A two-finger tap on table views that support multiple selection sets the table view to editing, if it is not already, and selects the tapped row. Unlike a single-finger tap, which toggles selection, the two- finger tap always selects the tapped row and has no effect if the row is already selected. This new gesture is enabled only in apps built for iOS 11. (29127664)
UITableView has a new property, separatorInsetReference, that changes how a custom value set in the separatorInset property is interpreted. By default, the value is .fromCellEdges, which means that custom separatorInset values are always interpreted as an inset from the edges of the cell, even in cases where table view would normally use larger automatic insets for the separator, such as a very wide table view when the cellLayoutMarginsFollowReadableWidth property is true.Set the separatorInsetReference to .fromAutomaticInsets to use the separatorInset as a fixed distance from the automatic inset that a table view would normally use.
Note that you can always use UITableViewAutomaticDimension for any edge of the separatorInset that you set, to receive the automatic inset on that edge. (31000402)

Table views now use estimated heights by default, which also means that cells and section header/footer views now self-size by default. The default value of the estimatedRowHeight, estimatedSectionHeaderHeight, and estimatedSectionFooterHeight properties is now UITableViewAutomaticDimension, which means the table view selects an estimated height to use. You should still provide a more accurate estimate for each property if possible, which is your best guess of the average value of the actual heights. If you have existing table view code that behaves differently when you build your app with the iOS 11 SDK, and you don’t want to adopt self-sizing, you can restore the previous behavior by disabling estimated heights by setting a value of zero for each estimated height property.

The behavior of the delete swipe action has been changed.When implementing commitEditingStyle: to delete a swiped row, delete the row in the data source and call deleteRowsAtIndexPaths: on the table view to show the swipe delete animation. Not calling deleteRowsAtIndexPaths inside of this method results in the swiped row resetting to its resting position. Do not display a confirmation dialog in the implementation of this method, and support undo to allow canceling a deletion. To show a confirmation dialog, use a UIContextualAction instead (described next).
When implementing a destructive UIContextualAction, delete the row in the data source and call the completion handler with true. Do not call deleteRowsAtIndexPaths: in this case. If the deletion fails, call the completion false to cancel the deletion. Although it should generally be avoided, you can show a confirmation dialog to confirm the deletion, and then call the completion handler with true if the user confirms (after deleting the row from its data source), or with false if the user cancels. It is also advised to disable performsFirstActionWithFullSwipe on the UISwipeActionsConfiguration in this case. Note that the completion handler must be called in all cases. (31588888)
When the user selects one of the Accessibility Larger Text content sizes as their preferred content size, UITableViewCell uses a new default layout that is optimized for the larger sizes. The numberOfLines property of UITableViewCell labels (both textLabel and detailTextLabel) changes to 0 (unlimited) by default when the Accessibility content sizes are in use. You may override this by explicitly setting the numberOfLines property. The standard image view and accessory views are aligned with the first line of text in the cell, and cell text wraps around the image in order to maximize the amount of text displayed per line. For the Value1, Value2, and Subtitle styles, the detailTextLabel is arranged underneath the standard textLabel. For UISwitch accessory views, the switch is located below the labels and aligned with the leading edge of the text. Because of these changes, which increase the height of the cell content at Accessibility content sizes, it’s important to use self-sizing cells to ensure that the row height increases as necessary, and to avoid using a fixed row height for all content sizes.

TheimageNamed:inBundle:compatibleWithTraitCollection:classmethod of UIImage now properly infers the UIDisplayGamut trait if it is not explicitly provided.If you are deploying to earlier versions of iOS, to provide the UIDisplayGamut trait in the trait collection, you pass to imageNamed:inBundle:compatibleWithTraitCollection:. You can obtain the correct value of this trait from the window or view that will display the image. Failing to provide the value can result in images failing to load on devices with P3 displays if the sRGB renditions of those images had been thinned out of the asset catalog. (29915518)
