• Support Android platform. see android_api_21 branch.

Usage

# uncompress the jniLibs to the `host_swift_project/.build` directory
# `host_swift_project` is the project that depends on `skia_swift_cross_platform`

tar -zxvf jniLibs.7z -C host_swift_project/.build

let package = Package(
    name: packageName,
    products: addGenerated([
    ]),
    dependencies: [
        .package(url: "https://github.com/Guang1234567/Skia_Swift_CrossPlatform.git", .branch("android_api_21"))
    ],

    targets: addGenerated([
        .target(name: packageName,
                dependencies: [
                    "SkiaSwift"
                ]),

=============================

SkiaSwift

Swift wrapper for SkiaSharp's C API

See:

• SkiaSharp's C API, which is a fork of Skia, to add more features to the original Skia's C API
• CSkiaSwift

This project uses Swift Package Manager:

• https://github.com/apple/swift-package-manager/blob/master/Documentation/Usage.md
• https://github.com/apple/swift-package-manager/blob/master/Documentation/PackageDescription.md
• https://clang.llvm.org/docs/Modules.html

Build SkiaSharp's Skia fork

Download SkiaSharp's Skia fork, then see these doc to build:

• https://skia.org/user/download
• https://skia.org/user/build
• https://stackoverflow.com/questions/50228652/how-to-compile-skia-on-windows
• https://github.com/flutter/engine/blob/master/tools/gn

Build static libraries:

bin/gn gen out --args="is_debug=false is_official_build=true \
skia_use_system_expat=false skia_use_system_libjpeg_turbo=false \
skia_use_system_libpng=false skia_use_system_libwebp=false \
skia_use_system_zlib=false skia_use_system_icu=false \
skia_use_system_harfbuzz=false"

ninja -C out

Build CSkiaSwift

Create symlinks to the built Skia above (only include/c and out directories are used):

cd Sources/CSkia/include
ln -s /path/to/skia/include/c

cd Sources/CSkia
ln -s /path/to/skia/out

Build:

swift build
swift build -c release

Run:

swift run Demo
.build/debug/Demo
.build/release/Demo
