(Don't include 183 | the brackets!) The text should be enclosed in the appropriate 184 | comment syntax for the file format. We also recommend that a 185 | file or class name and description of purpose be included on the 186 | same "printed page" as the copyright notice for easier 187 | identification within third-party archives. 188 | 189 | Copyright [yyyy] [name of copyright owner] 190 | 191 | Licensed under the Apache License, Version 2.0 (the "License"); 192 | you may not use this file except in compliance with the License. 193 | You may obtain a copy of the License at 194 | 195 | http://www.apache.org/licenses/LICENSE-2.0 196 | 197 | Unless required by applicable law or agreed to in writing, software 198 | distributed under the License is distributed on an "AS IS" BASIS, 199 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 200 | See the License for the specific language governing permissions and 201 | limitations under the License. 202 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | 2 | # Swift Android Gradle plugin ![Maven Central](https://img.shields.io/maven-central/v/com.readdle.android.swift/gradle) 3 | 4 | This plugin integrates [Swift Android Toolchain](https://github.com/readdle/swift-android-toolchain) to Gradle 5 | 6 | ## Pre-requirements 7 | 8 | This plugin requires **Android NDK** and the **Swift Android Toolchain**. Follow the [installation guide](https://github.com/readdle/swift-android-toolchain) to set them up. 9 | 10 | The plugin looks up the NDK and toolchain using the environment variables `ANDROID_NDK_HOME` and `SWIFT_ANDROID_HOME`, or by reading `local.properties` in the project root: 11 | 12 | ndk.dir=/path/to/ndk 13 | swift-android.dir=/path/to/toolchain 14 | 15 | ## Setup 16 | 17 | Plugin build swift code using [SwiftPM](https://github.com/apple/swift-package-manager) so you should define you code inside SwiftPM modules. Root module should be located inside `app/src/main/swift`. See [sample](https://github.com/andriydruk/swift-weather-app/tree/master/android/app/src/main/swift). 18 | 19 | #### Adding plugin to gradle scripts 20 | 1. Add the following to your root build.gradle 21 | 22 | ```gradle 23 | buildscript { 24 | repositories { 25 | mavenCentral() 26 | } 27 | dependencies { 28 | classpath 'com.readdle.android.swift:gradle:6.0.3' 29 | } 30 | } 31 | ``` 32 | 33 | 2. Add the following to your project build.gradle 34 | 35 | ```gradle 36 | apply plugin: 'com.readdle.android.swift' 37 | ``` 38 | 39 | 3. Configure build types and arhitecture 40 | 41 | ```gradle 42 | buildTypes { 43 | release { 44 | debuggable false 45 | // Build Swift in release mode 46 | jniDebuggable false 47 | // all 4 arhitectures 48 | } 49 | debug { 50 | debuggable true 51 | // Build Swift in debug mode 52 | jniDebuggable true 53 | // only 2 arhitectures 54 | ndk { 55 | abiFilters = ["arm64-v8a", "x86_64"] 56 | } 57 | } 58 | } 59 | ``` 60 | 61 | 4. Optionally you can add some extra configuration to your project build.gradle. For example: 62 | 63 | ```gradle 64 | swift { 65 | // Enables swift clean when ./gradlew clean invoked. Default true 66 | cleanEnabled false 67 | 68 | // Custom swift flags for debug build 69 | debug { 70 | // Set custom preprocessor flags 71 | extraBuildFlags "-Xswiftc", "-DDEBUG" 72 | } 73 | 74 | // Custom swift flags for release build 75 | release { 76 | // enable symbols in relase mode 77 | extraBuildFlags "-Xswiftc", "-g" 78 | } 79 | } 80 | ``` 81 | 82 | ## Usage 83 | 84 | In simple cases you can just run `./gradlew assembleDebug` and everything will work. 85 | 86 | #### Other SwiftPM to gradle mapping: 87 | 88 | | Gradle | SwiftPM | 89 | |--------------------------------|---------------------------------------| 90 | | `./gradlew swiftClean` | `swift package clean` | 91 | | `./gradlew swiftBuildDebug` | `swift build` | 92 | | `./gradlew swiftBuildRelease` | `swift build --configuration release` | 93 | | `./gradlew swiftPackageUpdate` | `swift package update` | 94 | 95 | ## Sample 96 | 97 | See [sample app](https://github.com/andriydruk/swift-weather-app). 98 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | buildscript { 2 | repositories { 3 | jcenter() 4 | maven { 5 | url "https://plugins.gradle.org/m2/" 6 | } 7 | } 8 | dependencies { 9 | classpath 'io.github.gradle-nexus:publish-plugin:1.1.0' 10 | } 11 | } 12 | 13 | apply plugin: 'groovy' 14 | apply plugin: 'idea' 15 | apply plugin: 'io.github.gradle-nexus.publish-plugin' 16 | apply from: "${rootDir}/publish-root.gradle" 17 | 18 | repositories { 19 | jcenter() 20 | google() 21 | } 22 | 23 | dependencies { 24 | implementation gradleApi() 25 | implementation localGroovy() 26 | implementation "commons-configuration:commons-configuration:1.10" 27 | compileOnly 'com.android.tools.build:gradle:4.1.0' 28 | } 29 | 30 | java { 31 | withSourcesJar() 32 | withJavadocJar() 33 | } 34 | 35 | ext { 36 | // Provide your own coordinates here 37 | PUBLISH_GROUP_ID = 'com.readdle.android.swift' 38 | PUBLISH_ARTIFACT_ID = 'gradle' 39 | PUBLISH_VERSION = '6.1.0' 40 | } 41 | 42 | apply from: "${rootProject.projectDir}/publish-module.gradle" 43 | -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/readdle/swift-android-gradle/15aa9eb64c06cda875c69703e78cfe5f6fb8e474/gradle/wrapper/gradle-wrapper.jar -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | distributionBase=GRADLE_USER_HOME 2 | distributionPath=wrapper/dists 3 | distributionUrl=https\://services.gradle.org/distributions/gradle-8.9-bin.zip 4 | networkTimeout=10000 5 | validateDistributionUrl=true 6 | zipStoreBase=GRADLE_USER_HOME 7 | zipStorePath=wrapper/dists 8 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | # 4 | # Copyright © 2015-2021 the original authors. 5 | # 6 | # Licensed under the Apache License, Version 2.0 (the "License"); 7 | # you may not use this file except in compliance with the License. 8 | # You may obtain a copy of the License at 9 | # 10 | # https://www.apache.org/licenses/LICENSE-2.0 11 | # 12 | # Unless required by applicable law or agreed to in writing, software 13 | # distributed under the License is distributed on an "AS IS" BASIS, 14 | # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 15 | # See the License for the specific language governing permissions and 16 | # limitations under the License. 17 | # 18 | # SPDX-License-Identifier: Apache-2.0 19 | # 20 | 21 | ############################################################################## 22 | # 23 | # Gradle start up script for POSIX generated by Gradle. 24 | # 25 | # Important for running: 26 | # 27 | # (1) You need a POSIX-compliant shell to run this script.
