 ## What is new?
 
-Support for gtk 4 was added via the `gtk4` branch.
+This branch supports Swift 5.2, but is now unmaintained.
+The `main` and `development` branches will require newer versions of Swift.
+
+Support for gtk 4 for Swift 5.2 is available via the `gtk4-swift52` branch.
+
+Version 12 of gir2swift pulls in [PR#10](https://github.com/rhx/gir2swift/pull/10), addressing several issues:
+
+- Improvements to the Build experience and LSP [rhx/SwiftGtk#34](https://github.com/rhx/SwiftGtk/issues/34)
+- Fix issues with LLDB [rhx/SwiftGtk#39](https://github.com/rhx/SwiftGtk/issues/39)
+- **Controversial:** Implicitly marks all declarations named "priv" as if they had attribute `private=1`
+- Prevents all "Private" records from generating unless generated in their instance record
+  - `-a` option generates all records
+- Introduces CI
+- For Class metadata types no longer generates class wrappers. Ref structs now contain static method which returnes the GType of the class and instance of the Class metatype wrapped in the Ref struct.
+- Adds final class GWeak<T> where T could be any Ref struct of a type which supports ARC. This class is a property wrapper which contains weak reference to any instance of T. This is especially beneficial for capture lists.
+- Adds support for weak observation.
+- Constructors and factories of GObjectInitiallyUnowned classes now consume floating reference upon initialisation as advised by [the GObject documentation](https://developer.gnome.org/gobject/stable/gobject-The-Base-Object-Type.html)
+
+Partially implemented:
+- Typed signal generation. Issues shown in [rhx/SwiftGtk#35](https://github.com/rhx/SwiftGtk/issues/35) hat remain to be addressed are listed here: [mikolasstuchlik/gir2swift#2](https://github.com/mikolasstuchlik/gir2swift/pull/2).

+### Other Notable changes
+
+Version 11 introduces a new type system into `gir2swift`,
+to ensure it has a representation of the underlying types.
+This is necessary for Swift 5.3 onwards, which requires more stringent casts.
+As a consequence, accessors can accept and return idiomatic Swift rather than
+underlying types or pointers.
+This means that a lot of the changes will be source-breaking for code that
+was compiled against libraries built with earlier versions of `gir2swift`.
+
+ * Requires Swift 5.2 or later (Swift 5.3 is required for the `gtk4` branch)
+ * Uses the namespace referenced in the `gir` file
+ * Wrapper code is now `@inlinable` to enable the compiler to optimise away most of the wrappers
+ * Parameters and return types use more idiomatic Swift (e.g. `Ref` wrappers instead of pointers, `Int` instead of `gint`, etc.)
+ * Functions that take or return records now are templated instead of using the type-erased Protocol
+ * `ErrorType` has been renamed `GLibError` to ensure it neither clashes with `Swift.Error` nor the `GLib.ErrorType`  scanner enum
+ * Parameters or return types for records/classes now use the corresponding, lightweight Swift `Ref` wrapper instead of the underlying pointer
 
-Version 15 of gir2swift provides a Package Manager Plugin.  This requires Swift 5.6 or higher.
-(older versions can be used via the [swift52](https://github.com/rhx/SwiftGdk/tree/swift52) branch).
 
 ## Prerequisites

Test that your compiler works using `swift --version`, which should give you something like
 
 	$ swift --version
-	swift-driver version: 1.45.2 Apple Swift version 5.6 (swiftlang-5.6.0.323.62 clang-1316.0.20.8)

+    Target: x86_64-apple-macosx12.0
 
 on macOS, or on Linux you should get something like:
 
 	$ swift --version
-	Swift version 5.6.1 (swift-5.6.1-RELEASE)
+	Swift version 5.5.2 (swift-5.5.2-RELEASE)
 	Target: x86_64-unknown-linux-gnu
 
 ### Gtk 3.22 or higher
 
-The Swift wrappers have been tested with glib-2.56, 2.58, 2.60, 2.62, 2.64, 2.66, 2.68, 2.70 and 2.72, and gdk/gtk 3.22 and 3.24 as well as 4.0, 4.2, 4.4, and 4.6 on the gtk4 branch.  They should work with higher versions, but YMMV.  Also make sure you have `gobject-introspection` and its `.gir` files installed.

 #### macOS
 
 On macOS, you can install gdk and gtk using HomeBrew (for setup instructions, see http://brew.sh).  Once you have a running HomeBrew installation, you can use it to install a native version of gtk:
 
 	brew update

+	brew install gtk4 glib glib-networking gobject-introspection pkg-config
 
 ## Usage
 
 Normally, you don't build this package directly (but for testing you can - see 'Building' below). Instead you need to embed SwiftGdk into your own project using the [Swift Package Manager](https://swift.org/package-manager/).  After installing the prerequisites (see 'Prerequisites' below), add `SwiftGdk` as a dependency to your `Package.swift` file, e.g.:
 
 ```Swift
-// swift-tools-version:5.6
+// swift-tools-version:5.3
 
 import PackageDescription
 
 let package = Package(name: "MyPackage",
     dependencies: [
-        .package(url: "https://github.com/rhx/gir2swift.git", branch: "main"),
-        .package(url: "https://github.com/rhx/SwiftGdk.git",  branch: "gtk3"),
+        .package(name: "gir2swift", url: "https://github.com/rhx/gir2swift.git", .branch("main")),
+        .package(name: "Gdk", url: "https://github.com/rhx/SwiftGdk.git", .branch("gtk4")),
     ],
-    targets: [
-        .target(name: "MyPackage",
-                dependencies: [
-                    .product(name: "Gdk", package: "SwiftGdk")
-                ]
-        )
-    ]
+    targets: [.target(name: "MyPackage", dependencies: ["Gdk"])]
 )
 ```

+this probably means that your Swift toolchain is too old, particularly on Linux (at the time of this writing, some Linux distributions require at least Swift 5.5).  Make sure the latest toolchain is the one that is found when you run the Swift compiler (see above).
 
   If you get an older version, make sure that the right version of the swift compiler is found first in your `PATH`.  On macOS, use xcode-select to select and install the latest version, e.g.:
 
 	sudo xcode-select -s /Applications/Xcode.app
 	xcode-select --install
+
+### Known Issues
+
+ * When building, a lot of warnings appear.  This is largely an issue with automatic `RawRepresentable` conformance in the Swift Standard library.  As a workaround, you can turn this off by passing the `-Xswiftc -suppress-warnings` parameter when building.
+
+ * The current build system does not support directory paths with spaces (e.g. the `My Drive` directory used by Google Drive File Stream).
+
+ * BUILD_DIR is not supported in the current build system.
+ 
+As a workaround, you can use the old build scripts, e.g. `./build.sh` (instead of `run-gir2swift.sh` and `swift build`) to build a package.
