The studio's macOS project drops CocoaPods. Every macOS plugin it uses
is a Swift package, so the Podfile was wrapping nothing but FlutterMacOS
in a `Pods_Runner` framework. It differed from Flutter's template only
by `use_modular_headers!`, a 2022 leftover that no pod has needed since
the last plugin pod left. That is why the SDK called it non-standard and
asked for a manual migration.

## The change

`pod deintegrate` in `app/macos`, then delete the Podfile and its lock,
the `Pods-Runner` xcconfig includes and the Pods project in
`Runner.xcworkspace`. The workspace now matches the SDK's own template
byte for byte. The diff is deletions only.

Nothing had to move into the Xcode project. The Podfile's `platform
:osx, '12.0'` only ever applied to the Pods targets, and the project
already sets `MACOSX_DEPLOYMENT_TARGET = 12.0`. The runner already has
`@executable_path/../Frameworks` in its runpath. Nothing reads the
`COCOAPODS=1` define.

## What it buys: a first run that needs no CocoaPods

The launcher builds the studio in a fresh working copy on a user's first
run (`DesktopGui.build`). With the Podfile present, that build ran `pod
install`, and on a machine without CocoaPods it stopped:

| Clean `flutter build macos --release` | before | after |
|---|---|---|
| CocoaPods installed | builds | builds |
| No CocoaPods on `PATH` | **fails**: "CocoaPods not installed or not in
valid state." | builds |

`tool/publish/install_check.dart --gui` also passes locally with no
CocoaPods on `PATH` and an empty flutter config. That is the hosted
first-run path: pack, unpack, resolve, build the CLI, build the studio.
CI never saw the failure because GitHub's macOS runners ship CocoaPods.

## Build time: the same within noise

These were clean builds (`flutter clean`, `Pods/` removed as in a fresh
copy), alternating the two trees to cancel out load drift. Load average
on the machine was 13–34.

| | runs (s) | median |
|---|---|---|
| before (CocoaPods) | 57.1, 56.9, 58.8 | 57.1 |
| after (SwiftPM only) | 55.2, 56.2, 94.2* | 56.2 |

\* The log is line for line the same as the 56 s run, so the extra time
was other work on the machine. `pod install` itself took 0.42–0.47 s,
because the only pod was FlutterMacOS. The SDK's "improve the project's
build time" is about one second here.

## The Swift Package Manager setting

- **Nothing needs to be set.** SwiftPM is on by default on stable since
Flutter 3.44.0 (flutter/flutter#184495), and the package's floor is
3.47.0. A build with `enable-swift-package-manager` *(Not set)* uses
Swift packages and needs no Podfile. Tested with an empty flutter config
dir.
- **An explicit opt-out still builds, the old way.** With
`enable-swift-package-manager: false` set globally, the SDK writes a
template Podfile into the working copy, re-integrates Pods, runs `pod
install` and builds, so the plugins become pod frameworks. That is where
every user was before this change. They need CocoaPods, and anyone who
opted out of SwiftPM has it.
- **The launcher cannot usefully pass the flag.** In
`FlutterFeaturesConfig` the environment variable ranks *below* the
global config (`pubspec ?? global ?? env ?? channel default`), even
though a comment in `flutter_features.dart` says the opposite. Measured:
a global opt-out plus `FLUTTER_SWIFT_PACKAGE_MANAGER=true` still ran
`pod install`. The only override is `flutter: config:
enable-swift-package-manager: true` in `app/pubspec.yaml`, which does
win over the opt-out (tested). It is left out: it would override a
choice the user made on purpose, to spare a case that already builds.

## Checked on the running studio

- Studio (dev) launches on the migrated project with no CocoaPods
warning and no plugin errors.
- `url_launcher`: `canLaunchUrl` round trip, `true`.
- `package_info_plus`: platform channel round trip,
`dev.flutterware.studio 0.6.0`.
- `file_selector`: *Save the screenshot as PNG…* presented its panel.
There was no channel error, and the call stayed pending on it.
- `webview_flutter`: this branch cherry-picked onto the Worlds mail-view
work. A clean release build pulls `webview_flutter_wkwebview` in as a
Swift package with no Podfile. In the running studio, *Pickup order* →
*Mia orders a flat white* → *Mail* → *Read it* → *Page*, the live
WKWebView held the rendered mail. Its text was read back from WebKit.
