Description Rolf Bjarne Kvinge [MSFT] 2017-09-15 11:43:06 UTC
Repro:

1. build

* cd msbuild/tests/MyWatch2Container (in xamarin-macios)
* msbuild /verbosity:diag /p:Platform=iPhone /p:Configuration=Release (https://gist.github.com/rolfbjarne/b9842148818648d4e21da762e0235f02)

2. check that a lot of symbols are still present in the extension

* nm bin/iPhone/Release/MyWatch2Container.app/Watch/MyWatchApp2.app/PlugIns/MyWatchKit2Extension.appex/MyWatchKit2Extension | wc
   25049   74903 1212380

3. strip the extension

*  strip -s ../MyWatchKit2Extension/obj/iPhone/Release/mtouch-symbols.list  bin/iPhone/Release/MyWatch2Container.app/Watch/MyWatchApp2.app/PlugIns/MyWatchKit2Extension.appex/MyWatchKit2Extension

4. the number of symbols is significantly smaller now

* nm bin/iPhone/Release/MyWatch2Container.app/Watch/MyWatchApp2.app/PlugIns/MyWatchKit2Extension.appex/MyWatchKit2Extension | wc
     302     605    7847
Comment 1 Jeffrey Stedfast 2017-10-13 17:35:16 UTC
The problem is the following evaluation for _GenerateAppExtensionDebugSymbols:

Target "_GenerateAppExtensionDebugSymbols" skipped, due to false condition; ('$(ComputedPlatform)' == 'iPhone' And '$(IsAppExtension)' == 'false' And '$(IsWatchApp)' == 'false') was evaluated as ('iPhone' == 'iPhone' And 'False' == 'false' And 'True' == 'false').


Current git master of Xamarin.iOS.Common.targets no longer checks $(IsWatchApp) == 'false' as of https://github.com/xamarin/xamarin-macios/pull/2215
