experiments in a post-browser web
fix(ios): silence build warnings and update Xcode project settings
- Add IPHONEOS_DEPLOYMENT_TARGET=16.0 to build-release.sh to eliminate
'built for newer iOS version' linker warnings on ring/sqlite/AppGroupBridge
- Replace deprecated contentEdgeInsets with UIButton.Configuration API
in ShareViewController (iOS 15+ deprecation)
- Apply Xcode recommended settings (remove deprecated Swift embedding
settings, auto-select architectures, inherit dev team from project)
- Document new troubleshooting entries: linker version warnings,
stale DerivedData workspace mismatch, Xcode recommended settings

### "Built for newer iOS version" Linker Warnings
745
+
746
+
**Symptom:** Dozens of linker warnings like `Object file (libapp.a[...]) was built for newer 'iOS' version (26.2) than being linked (16.0)`.
747
+
748
+
**Cause:** The Rust build compiled C objects (ring crypto, sqlite, AppGroupBridge) using the system SDK's default deployment target instead of the project's iOS 16.0 target.
749
+
750
+
**Fix:** Both build scripts (`build-ios.sh` and `build-release.sh`) must set `export IPHONEOS_DEPLOYMENT_TARGET=16.0` before `cargo build`. This is already done — if warnings reappear, check that the env var is still present.
751
+
752
+
### Xcode Points at Wrong Workspace
753
+
754
+
**Symptom:** Build fails with `search path '.../ios-fixes-XXXX/...' not found` or similar, pointing at an old/different jj workspace.
755
+
756
+
**Cause:** Xcode's DerivedData caches `$(PROJECT_DIR)` from whichever workspace the project was first opened from.
757
+
758
+
**Fix:**
759
+
1. Quit Xcode completely
760
+
2. Delete stale DerivedData: `rm -rf ~/Library/Developer/Xcode/DerivedData/peek-save-*`
761
+
3. Reopen from the correct workspace: `open backend/tauri-mobile/src-tauri/gen/apple/peek-save.xcodeproj`
762
+
763
+
### Xcode "Update to Recommended Settings"
764
+
765
+
When Xcode prompts to update settings, accept all **except "Enable User Script Sandboxing"** — that would break the "Build Rust Code" run script phase which needs filesystem access outside the sandbox.
