Can't build project on iOS Error code 70, how to fix it?

Question

Im not able to build my project (created with js, vue.js, vuex) on iOS platform. Exactly the same project works on web while typing npm run dev and I was able to build it on Android on laptop with Windows. When I’m trying Cordova run iOS got something like this:

xcodebuild: error: Unable to find a destination matching the provided 
destination specifier: --HERE a lot of simulators-- Ineligible destinations 
for the "HelloCordova" scheme: { platform:iOS, id:dvtdevice-DVTiPhonePlaceholder-
iphoneos:placeholder, name:Generic iOS Device } { platform:iOS Simulator, 
id:dvtdevice-DVTiOSDeviceSimulatorPlaceholder-iphonesimulator:placeholder, name:Generic iOS Simulator Device }
CordovaError: Promise rejected with non-error: 'Error code 70 for command: xcodebuild with args: -xcconfig,/Users/username/Downloads/vue-webpack-vuetify-vuex-cordova-boilerplate-master copy/platforms/ios/cordova/build-debug.xcconfig,-workspace,HelloCordova.xcworkspace,-scheme,HelloCordova,-configuration,Debug,-sdk,iphonesimulator,-destination,platform=iOS Simulator,name=iPhone X,build,CONFIGURATION_BUILD_DIR=/Users/username/Downloads/vue-webpack-vuetify-vuex-cordova-boilerplate-master copy/platforms/ios/build/emulator,SHARED_PRECOMPS_DIR=/Users/username/Downloads/vue-webpack-vuetify-vuex-cordova-boilerplate-master copy/platforms/ios/build/sharedpch' 
at cli.catch.err (/usr/local/lib/node_modules/cordova/bin/cordova:30:15) at process._tickCallback (internal/process/next_tick.js:68:7)

Iv also tried cordova build ios -- --buildFlag="-UseModernBuildSystem=0" but got the same error. Im using Xcode 10.1 and Cordova 8.1.2

Atm working on MacBook Pro

Answer 1

xcodebuild error 70 means that the target for the build was not found. It could be due to a mismatch of iOS versions, parameters, or (if using a real device) the UDID being wrong, or the device was not connected, switched off or locked.

In my case it was because my iPhone and my Macbook were not on the same wifi. – Busty

Answer 2

I've had this problem with react-native, if developer mode is not enabled on the iOS device, you'll get this error 70

Answer 3

In my case it was because my XCode was out-of-date and not compatible with the version of iOS on my iPhone.

Answer 4

Issue occurs when xcode gets updated to latest and new platform version is available in xcode.

I resolved it by downloading the latest platform version

Before 17.0 was installed with xcode 15.0

After xcode auto updated to 15.1

17.2 was available, so i have resolved by installing 17.2 platform

Answer 6

I had a same issue like error code 70 and I fixed the following step.

Situation

I try to execute xcodebuild after I changed the verion of Xcode for building (16.0 => 15.4).

It happned.

Cause

Incompatiblity of target build iOS device or simulator. I hadn't installed iOS 17.5 emulator (had installed only iOS 18.0 emulator for Xcode 16).

Solution

1. Install emulator or connect a suitable iOS device that is able to build by the Xcode version you are using.

2. Execute 'Clean Build Folder'

3. try 'xcodebuild' again.

Answer 7

In my project.pbxproj file setting value of IPHONEOS_DEPLOYMENT_TARGET was higher then on emulator so I changed it to emulator ios version number and the problem was gone
