Summary: The SwiftPM setup adds a "Sync SPM Autolinking" pre-action to the app's Xcode scheme. The pre-action never ran its sync step. The script is many lines long. `escapeXmlAttribute` wrote it into the `scriptText` XML attribute with raw line breaks. An XML parser replaces each raw line break in an attribute value with a space (XML 1.0 §3.3.3). So Xcode read the script as one line. The second line of the script is a `#` comment, so everything after `set -euo pipefail` became part of that comment. This PR makes two changes in `packages/react-native/scripts/spm/generate-spm-xcodeproj.js`: - `escapeXmlAttribute` now also encodes `\r`, `\n` and `\t` as `&https://github.com/react/react-native/issues/13;`, `&https://github.com/react/react-native/issues/10;` and `&https://github.com/react/react-native/issues/9;`. Xcode itself writes the script this way. - `deinit` deletes a scheme that RN created only when the scheme is still unchanged. This check now ignores the value of the script. Without this change, a scheme that an older version wrote with raw line breaks would no longer match, and `deinit` would leave it on disk. The XML decoder had no callers left after this change, so this PR removes it. Existing projects get the fixed script when the user runs `npx react-native spm update` once. The build-time `sync` does not rewrite the scheme. ## Changelog: [IOS] [FIXED] - SwiftPM: keep line breaks in the scheme pre-action script so that the "Sync SPM Autolinking" pre-action runs. Run `npx react-native spm update` once to rewrite an existing scheme. Pull Request resolved: #58826 Test Plan: New tests: - `generate-spm-xcodeproj-test.js`: parses the generated scheme with `xmldom/xmldom` and checks that the script keeps its line breaks and tabs. A second test checks that a refresh of an older scheme with raw line breaks writes `&https://github.com/react/react-native/issues/10;`. - `remove-spm-injection-test.js`: checks that `deinit` still deletes an RN-created scheme whose script has raw line breaks. ``` yarn jest --no-cache -i packages/react-native/scripts/spm/__tests__/generate-spm-xcodeproj-test.js packages/react-native/scripts/spm/__tests__/remove-spm-injection-test.js ``` - Before the fix: 2 failed, 124 passed (the two `generate-spm-xcodeproj` tests). - With only the encoding change: the new `deinit` test and 4 existing `deinit` tests failed. - With both changes: 2 suites passed, 126 tests passed. ESLint and Prettier pass on the changed files. `flow check-contents` reports no errors for `generate-spm-xcodeproj.js`. I did not build an app in Xcode for this PR. An Expo app had the problem: when the line breaks in its scheme were changed to `&https://github.com/react/react-native/issues/10;` by hand, the pre-action ran.
