Apple Releases iOS 13 Developer Beta 2 with OTAs, Plus Controls, and New Portrait Lighting Effect «iOS & iPhone :: Gadget Hacks



Undoubtedly, iOS 13 dominated the discussion in the Apple community this month. Since the announcement and release of the first developer beta, we have given iPhone users a wealth of new features and changes to explore and discuss. Now the fun continues with iOS 13 dev beta 2. Who is ready to start the conversation again?

Remember that this is not the public beta. So far, Apple has only released the iOS 13 beta for developers. If you think, "Wait, I'm not a developer, but I use iOS 13 …", it's because Apple Developer Accounts only provide direct access to the iOS 13 IPSW file. You probably have a friend who is a developer, or you took an extra step to find the IPSW file somewhere on the World Wide Web.

This latest beta update brings quite a few changes. Beta 2 immediately adds the lighting control in portrait mode and the new high-key mono-portrait mode, two features that were not considered in Beta 1

for developers. But that's not all. Here are all the new features we know with Dev Beta 2:

You'll also find a list of bug fixes, from books and CarPlay to maps and news. Read the full Release Notes for iOS 13 dev beta 2 below:

    UIKit – Neue Funktionen

    • Die UITableViewCell-Klasse ändert die backgroundColor- oder isOpaque-Eigenschaften der contentView und ihrer Unteransichten nicht mehr, wenn Zellen hervorgehoben oder ausgewählt werden. Wenn Sie eine undurchsichtige Hintergrundfarbe für Unteransichten der Zelle innerhalb (und einschließlich) der Inhaltsansicht festlegen, wirkt sich dies möglicherweise auf das Erscheinungsbild aus, wenn die Zelle hervorgehoben oder ausgewählt wird. Die einfachste Möglichkeit, Probleme mit Ihren Unteransichten zu beheben, besteht darin, sicherzustellen, dass die backgroundColor-Eigenschaft auf null oder klar und die undurchsichtige Eigenschaft auf falsch gesetzt ist. Bei Bedarf können Sie jedoch die Methoden setHighlighted (_: animated 🙂 und setSelected (_: animated 🙂 überschreiben, um diese Eigenschaften in Ihren Unteransichten manuell zu ändern, wenn Sie zu oder von den hervorgehobenen und ausgewählten Status wechseln. (13955336)
    • Seit iOS 8 muss für die Verwendung von UISearchController mit UINavigationController die definePresentationContext-Eigenschaft des Controllers für die Draufsicht auf true festgelegt werden. Andernfalls können subtile Fehler auftreten, die sich nur schwer erkennen und beheben lassen. Starting in iOS & iPadOS 13 beta, if a view controller's navigationItem has a non-nil searchController, when the view controller is shown in a navigation controller, UINavigationController automatically sets that view controller's definesPresentationContext property to true. If you are targeting earlier versions of iOS, set this property before your search controller becomes active. (31338934)
    • The UIRefreshControl class no longer directly modifies the contentInset of its scroll view. Instead, its adjustments to the content inset will be incorporated into the scroll view's adjustedContentInset. The only exception is when the scroll view's contentInsetAdjustmentBehavior is set to UIScrollView.ContentInsetAdjustmentBehavior.never, in which case the UIRefreshControl instance will modify the contentInset directly as it did in previous releases. (35866834)
    • If you implement self-sizing cells in a UITableView by overriding sizeThatFits(_:) without using Auto Layout, the height you return is interpreted as the desired height for the contentView of the cell, and UITableViewCell automatically adds any additional height needed to allow room for the cell separator. If you implement manual self-sizing this way, the cell's contentView width is guaranteed to be accurate for you to use in manual layout calculations when sizeThatFits(_:) is called on the UITableViewCell. (39742612)
    • Trait environments, such as views and view controllers, now have their traitCollection property populated with traits during initialization. These initial traits represent a prediction of the ultimate traits that the trait environment will receive when it gets added to the hierarchy. Because the traits that are populated during initialization are just a prediction, they might differ from the traits that are received once actually in the hierarchy. Therefore, when possible you should wait to perform work that uses the traitCollection until the view, or view controller's view, has moved into the hierarchy — meaning window returns a non-nil value — so that you don't have to throw away any work done using the predicted traits if the actual traits are different. The best time to use the traitCollection is during layout, such as inside layoutSubviews(), viewWillLayoutSubviews(), or viewDidLayoutSubviews().
    • The traitCollectionDidChange(_:) method is only called when the value of a trait changes. Importantly, because the trait collection is now initialized to a prediction of the ultimate traits in the destination hierarchy, when the initial predicted traits match the ultimate traits in the hierarchy, traitCollectionDidChange(_:) will not be called when the trait environment is added to the hierarchy. Because traitCollectionDidChange(_:) is intended to be an invalidation callback to notify you that one or more traits changed, audit your existing implementations of this method, as well as the UIContentContainer method willTransition(to:with:), for places where you might have been relying on it to trigger initial setup. The best place to lazily perform work that uses the traitCollection is inside one of the layoutSubviews methods discussed above, but remember that these layout methods are called any time layout occurs so be sure to avoid repeating work when you don't need to. (46818941)
    • You can now enable debug logging to easily see when traitCollectionDidChange(_:) or willTransition(to:with:) is called on your own classes. Turn on the logging by using the following launch argument: -UITraitCollectionChangeLoggingEnabled YES. You might want to temporarily disable the Main Thread Checker while using this launch argument and running your app from Xcode to avoid extra log messages for unrelated classes. (47858564)
    • The UITableViewCell class's contentView property is always laid out edge-to-edge with adjacent accessories, both on the leading and the trailing side. This streamlines the layout code so developers who want the correct default offset no longer have to align their content with the content view border or the layout margin depending on whether there is an accessory on the trailing side or not. You should now always lay out their code on the layout margins of the cell's content view to get the default system insets. These insets will be adjusted automatically based on the accessories visible in the cell to match the system's default spacing. (48214114)
    • You can now invoke a custom initializer from a creation block that's passed through instantiateInitialViewController(creator:) or instantiateViewController(identifier:creator:). This makes it possible for you to initialize view controllers with additional context and arguments, while taking advantage of defining them in a storyboard through Interface Builder. A custom controller initializer must call its super.init(coder:) method and pass the coder argument that it receives through the creation block. (48313869)

    • When running your app from Xcode, you might see console errors about UIKit classes that override the traitCollection getter. You can safely ignore these messages for system classes. If you see this error message for your own classes, it likely indicates a real issue for you to fix. (51651561)

To download and update your iPhone to iOS 13 dev beta 2, you will first need to be a registered developer with a valid configuration profile. You'll then need to download the profile for beta 2 from Apple's developer's site, either via the iPhone in Safari or another browser. Your system will ask if you want to install the profile. Say "Allow," then "Install" the new profile from Settings –> General –> Profiles. Restart when prompted, then you can check for OTA updates in "Software Update" to download and install beta 2. )You can also just download the restore image like w as needed for dev beta 1.)
