react-native - linking fails after upgrade : ld: symbol(s) not found for architecture x86_64

Question

i recently upgraded the react-native version with

react-native upgrade

and followed all steps without any errors so far. Now when i want to build the ios Version i get following Error:

❌  ld: symbol(s) not found for architecture x86_64
❌  clang: error: linker command failed with exit code 1 (use -v to see invocation)

** BUILD FAILED **

The following build commands failed:

Ld build/Build/Products/Debug-iphonesimulator/CustomName.app/CustomName normal x86_64

(1 failure)

The following commands produced analyzer issues:
Analyze Base/RCTModuleMethod.mm normal x86_64
Analyze RCTNetInfo.m normal x86_64
Analyze RCTImageCache.m normal x86_64
(3 commands with analyzer issues)

My Project Env

React Native Environment Info: System: OS: macOS 10.14.3 CPU: (8) x64 Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz Memory: 140.02 MB / 16.00 GB Shell: 3.2.57 - /bin/bash Binaries: Node: 11.7.0 - /usr/local/bin/node Yarn: 1.13.0 - /usr/local/bin/yarn npm: 6.5.0 - /usr/local/bin/npm Watchman: 4.9.0 - /usr/local/bin/watchman SDKs: iOS SDK: Platforms: iOS 12.1, macOS 10.14, tvOS 12.1, watchOS 5.1 IDEs: Xcode: 10.1/10B61 - /usr/bin/xcodebuild npmPackages: react: 16.6.3 => 16.6.3 react-native: 0.58.5 => 0.58.5 npmGlobalPackages: create-react-native-app: 2.0.2 react-native-cli: 2.0.1 react-native-git-upgrade: 0.2.7 react-native-rename: 2.4.0

So i checked to folder

build/Build/Products/Debug-iphonesimulator/

and could find an .app file which was disabled by System ( other react-native projects have a valid .app file )

So it seems like that the build is creating an invalid .app file which then ( understandable ) fails linking since the file / folder is not available.

Is there any chance to get a detailed insight what is causing this invalid .app file and how to fix it?

Any Hint is appreciated!
