I ran into problems upgrading my current app to NativeScript 3.0 on iOS so I tried the HelloWorld tutorial and I am having the same problem.
I executed the following steps
npm install -g nativescript tns --version > 3.0.0 tns create HelloWorld --template nativescript-template-ng-tutorial cd HelloWorld tns run ios
Everything builds and the iOS emulator launches but then I get this error:
Failed to install the requested application
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.
while executing xcrun simctl install 2C26F15F-4194-4D29-AC48-24ECE8A58115 /Users/rgardner/Development/HelloWorld/platforms/ios/build/emulator/HelloWorld.app.
I tried reinstalling platform ios and a few other suggestions I found, but nothing works.
I read in the RC notes that NS 3 doesn’t support XCode 8.3 but I can’t find that in the current docs, so I’m assuming it’s fixed. I am running XCode 8.3.2.
