You can now use momc on the command line to generate Core Data code from your models. A normalized file contains keys in alphabetical order and a newline character at the end of the file. Xcode normalizes Asset Catalog Contents.json files when modifying them, for better stability and compatibility with future edits. Resolved an issue where hidden folders inside an Asset Catalog could cause Xcode to repeatedly reload the catalog. The “New Asset” menu now organizes asset types by platform.

When “Optimize Interface for Mac” is selected, Xcode will prefer the Mac asset variant. Xcode will use this asset in targets that build with Mac Catalyst when “Scale Interface to Match iPad” is selected (including on macOS 10.15). The “Mac Catalyst” asset variant is now named “Mac Scaled”. You can use the asset’s Attribute inspector to hide the unused variant. If you leave this empty, Xcode will use the Any Appearance color value for both Light Appearance and Dark Appearance. (21135944)Īdding a new color now includes a Dark Appearance variant by default. The required pixel size is now shown for complication placeholder images. These preserve their vector representation with deployment targets of macOS 10.15 or later, iOS 13 or later, and iPadOS 13 or later. (61299833)Īdded support for Scalable Vector Graphic (SVG) image assets.

The as(1) driver will remain, as a standard way to invoke Clang’s integrated assembler, as well as any assemblers installed by the developer. Using the as command with the -Q flag shows a warning that instructs you to transition to Clang’s integrated assembler and the -q flag. The stand-alone system assemblers for i386, x86_64, and arm are deprecated.The compiler now emits an error for method calls with a block that uses parameters more specific than the arguments with which it will be called. (49917738)įixed type checking for block parameters using id with protocols. This additional error detection unifies Clang’s behavior for iOS/tvOS and macOS 64-bit targets for this diagnostic. (45503561)Ĭlang now reports an error when you use a function without an explicit declaration when building C or Objective-C code for macOS ( -Werror=implicit-function-declaration flag is on). on a property is ignored if the property is redeclared in a protocol that inherits from another protocol. This allows using blocks in new places like std::optional. The std::is_scalar trait is now true for Block types. (68252534)Ĭlang now warns about incorrect format strings that are specified in an NSLocalizedString macro.
(64037686)įixed an issue in Xcode 12 build 12A7208 which could cause build failures for iOS or tvOS apps using StoreKit or Authentication Services with SwiftUI, when targeting simulated devices or using SwiftUI Previews. (56087948, 58010475)Ĭompilable code completions for SwiftUI APIs now correctly handle overloaded methods. Completions are also more accurate and up to 15 times faster in Xcode 12. (56423420)Ĭode completions have a new, focused user interface, making it easier to find a completion. The new Librar圜ontentProvider protocol gives you the ability to show your views and modifiers in Xcode’s library. For more seamless live previewing on device, Xcode installs the new Xcode Previews app for iOS 14 and iPadOS 14. Xcode now supports previewing widgets, App Clips, and content in Swift packages. The tab bar appears when you have more than one document open, or you choose View > Always Show Tab Bar. Option-click or double-click to open a document in a tab. General New Featuresĭocuments can now be opened in their own tab, making it easy to quickly switch between files while maintaining the rest of Xcode’s configuration. Xcode 12 requires an Intel-based Mac running macOS Catalina 10.15.4 or later. The Xcode 12 release supports on-device debugging for iOS 9 and later, tvOS 9 and later, and watchOS 2 and later. Xcode 12 includes SDKs for iOS 14, iPadOS 14, tvOS 14, watchOS 7, and macOS Catalina 10.15.6.
