Pourquoi nous avons choisi Kotlin comme l'une de nos langues cibles. Partie 2: Kotlin Multiplatform

Après que le plugin kotlin a collecté pour nous un tas de différents frameworks pour différentes architectures, nous créons manuellement un nouveau framework universel dans lequel nous copions les métadonnées de n'importe quel (dans notre cas, nous avons pris arm64):

//add meta files (headers, modules and plist) from arm64 platform
task copyMeta() {
    dependsOn build

    doLast {
        copy {
            from("$buildDir/bin/iphone/main/release/framework/${frameworkName}.framework")
            into "$buildDir/iphone_universal/${frameworkName}.framework"
        }
    }
}

, , , . lipo, :

//merge binary files into one
task lipo(type: Exec) {
    dependsOn copyMeta

    def frameworks = files(
            "$buildDir/bin/iphone32/main/release/framework/${frameworkName}.framework/$frameworkName",
            "$buildDir/bin/iphone/main/release/framework/${frameworkName}.framework/$frameworkName",
            "$buildDir/bin/iphoneSim/main/release/framework/${frameworkName}.framework/$frameworkName"
    )
    def output = file("$buildDir/iphone_universal/${frameworkName}.framework/$frameworkName")
    inputs.files frameworks
    outputs.file output
    executable = 'lipo'
    args = frameworks.files
    args += ['-create', '-output', output]
}

, - Kotlin MPP Info.plist UIRequiredDeviceCapabilities, ( ). PlistBuddy:

//workaround
//remove UIRequiredDeviceCapabilities key from plist file (because we copy this file from arm64, only arm64 architecture was available)
task editPlistFile(type: Exec) {
    dependsOn lipo

    executable = "/bin/sh"
    def script = './scripts/edit_plist_file.sh'
    def command = "Delete :UIRequiredDeviceCapabilities"
    def file = "$buildDir/iphone_universal/${frameworkName}.framework/Info.plist"

    args += [script, command, file]
}

edit_plist_file.sh:

/usr/libexec/PlistBuddy -c "$1" "$2"

, zip ( podspec ):

task zipIosFramework(type: Zip) {
    dependsOn editPlistFile
    from "$buildDir/iphone_universal/"
    include '**/*'
    archiveName = iosArtifactName
    destinationDir(file("$buildDir/iphone_universal_zipped/"))
}

podspec :

task generatePodspecFile(type: Exec) {
    dependsOn zipIosFramework

    executable = "/bin/sh"

    def script = './scripts/generate_podspec_file.sh'

    def templateStr = "version_name"
    def sourceFile = './podspec/template.podspec'
    def replaceStr = "$version"

    args += [script, templateStr, replaceStr, sourceFile, generatedPodspecFile]
}

generate_podscpec_file.sh :

sed -e s/"$1"/"$2"/g <"$3" >"$4"

curl :

task uploadIosFrameworkToNexus(type: Exec) {
    dependsOn generatePodspecFile

    executable = "/bin/sh"
    def body = "-s -k -v --user \'$userName:$password\' " +
            "--upload-file $buildDir/iphone_universal_zipped/$iosArtifactName $iosUrlRepoPath"
    args += ['-c', "curl $body"]
}

task uploadPodspecFileToNexus(type: Exec) {
    dependsOn uploadIosFrameworkToNexus

    executable = "/bin/sh"
    def body = "-s -k -v --user \'$userName:$password\' " +
            "--upload-file $generatedPodspecFile $iosUrlRepoPath"
    args += ['-c', "curl $body"]
}

:

task createAndUploadUniversalIosFramework() {
    dependsOn uploadPodspecFileToNexus
    doLast {
        println 'createAndUploadUniversalIosFramework complete'
    }
}

Profit!
