+# Skia multiplatform samples
+
+## run iOS with Xcode
+ - Works only on Mac with Intel CPU (for now)
+ - Install xcodegen
+ - run `xcodegen`
+ - run `open SkikoSample.xcodeproj`
+
+## run iOS with debug in AppCode
+ - If you need to debug skiko sources without publish to maven local, then set environment variable `export SKIKO_COMPOSITE_BUILD=1` (on MacOS in ~/.zshrc)
+ - Install KMM plugin for AppCode
+ - In AppCode open samples/SkiaMultiplatformSample (File -> Open).
+Choose "Open as Project".
+![import-build-gradle-project.png](import-build-gradle-project.png)
+ - Set target device and Run
+![ios-run-in-appcode.png](ios-run-in-appcode.png)
+ - Now you may use breakpoints in common and native Kotlin code
+
+## run on browser:
+ - `./gradlew jsBrowserRun`
+
+## run desktop awt:
+ - `./gradlew runAwt`
+
+## run desktop on native MacOS
+ - `./gradlew runNative`
