v0.25 crashes on macOS 26.5 beta when opening menu — NSBundle.module fails to initialize localization bundle

[mingginwan]

Environment

• CodexBar: 0.25 (build 60)
• macOS: 26.5 beta (25F5068a), Apple Silicon (MacBookPro18,2)

What happens
CodexBar crashes immediately every time the menu bar icon is clicked. The app launches fine but crashes the moment the menu tries to open.

Crash cause
This is a regression introduced in v0.25 with the new localization feature. The SPM-generated NSBundle.module accessor (called via localizedBundle() → ClaudeProviderImplementation.appendUsageMenuEntries) fails to initialize CodexBar_CodexBar.bundle on macOS 26.5, triggering assertionFailure.

The bundle exists at the expected path (CodexBar.app/Contents/Resources/CodexBar_CodexBar.bundle), but its Info.plist only contains CFBundleDevelopmentRegion — missing CFBundlePackageType, CFBundleIdentifier, and other required keys. macOS 26.5 appears stricter about flat bundle validation, causing Bundle(url:) to return nil for all candidates.

Crash stack (key frames)

_assertionFailure(_:_:file:line:flags:)
closure #1 in variable initialization expression of static NSBundle.module
one-time initialization function for module   [dispatch_once]
localizedBundle()
ClaudeProviderImplementation.appendUsageMenuEntries(context:entries:)
MenuDescriptor.usageSection(for:store:settings:)
StatusItemController.populateMenu(_:provider:)
StatusItemController.menuWillOpen(_:)

Suggested fix
Ensure the generated CodexBar_CodexBar.bundle/Info.plist includes CFBundlePackageType = BNDL and CFBundleIdentifier. This can be done by adding a custom Info.plist to the SPM resource bundle target, or verifying the Xcode build settings for the bundle target produce a complete plist.

Not only on macOS beta, I am on Tahoe 26.3.1 (a) and I experience the same crash when clicked. Did not look for logs.

Confirming this crash is not beta-specific — reproduces on stable macOS 26.4.1 (25E253) too.

Environment

• CodexBar 0.25 (build 60), installed from GitHub release zip
• macOS 26.4.1 (25E253), release channel, Apple Silicon (Mac16,8)
• Sparkle 2.9.1 (auto-update enabled)
• Selected menu provider: claude (providerToggles = {antigravity=0, claude=1, codex=1, gemini=1})

Repro

1. Launch CodexBar 0.25 — status item appears normally.
2. Click the menu bar icon → instant crash, every time.
3. bug_type: 309, EXC_BREAKPOINT (SIGTRAP) at _assertionFailure from Bundle.module one-time init.

Top frames match the report exactly:

_assertionFailure(_:_:file:line:flags:)
closure #1 in variable initialization expression of static NSBundle.module
one-time initialization function for module
_dispatch_once_callout
localizedBundle()
specialized ClaudeProviderImplementation.appendUsageMenuEntries(context:entries:)
specialized static MenuDescriptor.usageSection(for:store:settings:)
StatusItemController.populateMenu(_:provider:)
StatusItemController.menuWillOpen(_:)

So affected OS range now spans at least 26.3.1, 26.4.1 release, and 26.5 beta — i.e. the SPM resource-bundle Info.plist issue you described is broader than the macOS 26.5 stricter-validation hypothesis suggests, and likely affects any 26.x.

Workaround: downgrading to v0.24 (build 59) fixes it immediately; menu opens without issue.

Happy to share the full .ips if it helps — ~/Library/Logs/DiagnosticReports/CodexBar-2026-05-11-041015.ips (incident E3BD0463-A19D-4FCA-B2A3-ED41F1CBA6DC, slice UUID 4ab62104-d928-36e8-bb81-cc89ed58d2ff).

Same.

Updating to https://github.com/steipete/CodexBar/releases/tag/v0.25.1 solve this.

[steipete]

Closing as fixed by the v0.25.1 localization-bundle crash fix. This is the same packaged Bundle.module/localization resource assertion class as #891/#896, and v0.25.1 shipped that fix.

Also rechecked the follow-up localization path while fixing #908: LocalizationBundleTests passes, and the full local swift test -q rerun passed with 2317 tests / 288 suites.

[steipete]

Verified fixed on current main.

This was the packaged app localization bundle crash: the app could still reach SwiftPM Bundle.module after being copied out of .build, which fails on this macOS 26.5 beta path. Current main resolves CodexBar_CodexBar.bundle from the app resources first and only falls back to Bundle.module for development runs.

Proof:

• swift test --filter LocalizationBundleTests --filter PreferencesPaneSmokeTests passed 6 Swift Testing tests.
• CODEXBAR_WIDGET_METADATA_TIMEOUT_SECONDS=240 ./Scripts/compile_and_run.sh created CodexBar.app and launched it successfully.

The packaged-app fix shipped in v0.25.1, so I am closing this as fixed.
