Code signing issue when using xcodetest

[tobiasbe]

Hi :)

I am facing an issue when trying to test my application using gradle.

Situation:

• Plugin version: 0.15.1+
• My application uses a pod that depends on a binary (Dynatrace)
• My tests use the host application + @testable import instead of adding each file to the test target separately
• This means that running xcodetest also builds the main application
• Application builds fine with xcodebuild, but testing would not work

What i've found out myself:

• According to --debug's output, it seems to be a code signing issue (see below)
• When i switch the host application's pod to a different one (like RxSwift), xcodetest works fine
• This might be related to https://github.com/openbakery/gradle-xcodePlugin/issues/346

How to reproduce:

• Use sample application that you can find attached
• Run pod install
• Run gradle xcodetest,Debug,DynTest,DynTest '-PsimulatorOS=11.*' -PsimulatorBuild=true --debug

Thanks in advance, Tobias

This is the part of the debug output i am referring to:

Ok the binary framework must be signed first.

A workaround for this is that you create a custom task that is executed after the cocoapodsInstall and before the test tasks an executes the following command:

/usr/bin/codesign --force --sign - --verbose ./Pods/Dynatrace/iOS/agent/Dynatrace.framework

Thank you, Rene.

This little workaround helps for now.

task manualCodeSign() {
    def command = "/usr/bin/codesign --force --sign - --verbose ./Pods/Dynatrace/iOS/agent/Dynatrace.framework"
    def proc = command.execute()
    proc.waitFor()
}

xcodetest {
    dependsOn manualCodeSign
}

@renep Unfortunately this did only work for the sample app. In my main app there seems to be yet another issue that makes xcodebuild fail with error code 65.

The question here is, why signing is relevant for a simulator build at all? I've recognized the following: When using the xcodetest task, it starts xcodebuild like this:

xcodebuild -scheme DynTest -workspace DynTest.xcworkspace -configuration Debug \
CODE_SIGN_IDENTITY= CODE_SIGNING_REQUIRED=NO \
-destination platform=iOS\ Simulator,id=9579DF94-884A-49A8-85EC-1842756997A8 \
-derivedDataPath /Users/tobiasbecker/Desktop/DynTest/connect-ios/build/derivedData \
DSTROOT=/Users/tobiasbecker/Desktop/DynTest/connect-ios/build/dst \
OBJROOT=/Users/tobiasbecker/Desktop/DynTest/connect-ios/build/obj \
SYMROOT=/Users/tobiasbecker/Desktop/DynTest/connect-ios/build/sym \
SHARED_PRECOMPS_DIR=/Users/tobiasbecker/Desktop/DynTest/connect-ios/build/shared \
-enableCodeCoverage yes test

When this command is run, xcodebuild runs the codesigning, even though in gradle i've specificied that i want to run a simulator build.

When i remove the CODE_SIGINING_IDENTITY= and CODE_SIGNING_REQUIRED=NO parts it does not code sign anything, which makes the tests run without any problems on both the sample app and my main project.

Is there any way to make the gradle-xcodePlugin not add these two or would that need a change?

[renep]

I have updated the plugin that the CODE_SIGINING_IDENTITY= and CODE_SIGNING_REQUIRED=NO is not added for a iOS simualtor build. Can you test the latest develop version if this solves this issue: https://github.com/openbakery/gradle-xcodePlugin/tree/develop#current-develop-version

Hi Rene,

thank you very much. This indeed solves the problem. :+1:

@tobiasbe Can this issue be closed now?

[tobiasbe]

Oh sure. Thanks for the reminder
