Using a local Skip build requires updating `Package.swift`

[dfabulich]

% cd /tmp
% skip init --transpiled-app --appid=some.app.id app-project AppName --no-build --git-repo
% cd app-project
% git commit -m "initial commit"
% cd ~/git/stonehack
% ls
skip			skipstone		stonehack.xcworkspace
% cd skipstone
% xcodebuild -workspace /tmp/app-project/Project.xcworkspace -scheme "AppName App" -destination "generic/platform=iOS Simulator" -skipPackagePluginValidation
Command line invocation:
    /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -workspace /tmp/app-project/Project.xcworkspace -scheme "AppName App" -destination "generic/platform=iOS Simulator" -skipPackagePluginValidation

xcodebuild: error: Could not resolve package dependencies:
  Failed to resolve dependencies Dependencies could not be resolved because root depends on 'skip' 1.7.2..<2.0.0.
'skip' >= 1.7.2 cannot be used because no versions of 'skip' match the requirement 1.7.3..<2.0.0 and package 'skip' is required using a stable-version but 'skip' depends on an unstable-version package 'skipstone'.

I was able to workaround this by modifying Package.swift in my project like this:

diff --git i/Package.swift w/Package.swift
index bdd4526..33bf955 100644
--- i/Package.swift
+++ w/Package.swift
@@ -10,7 +10,7 @@ let package = Package(

         .package(url: "https://source.skip.tools/skip-ui.git", from: "1.0.0")
     ],

But I don't remember that being required when I've hacked on Skip in the past; it's certainly not documented in the README.

I can reproduce this with:

xcodebuild -workspace ../skipapp-hello/Project.xcworkspace -scheme "HelloSkip App" -destination "generic/platform=iOS Simulator" -skipPackagePluginValidation

FTR, I don't know if we've tested with command-line xcodebuild builds; we mostly do local skipstone development by opening Xcode from the skipstone folder (which does work). That being said, I'm not sure why this doesn't work, since Xcode itself is just running xcodebuild…
