Flutter iOS Build System
Provenance: OFFICIAL SOURCE. Every step below is transcribed from the official Flutter guide —
https://docs.flutter.dev/deployment/ios(Flutter 3.44.7, page updated 2026-07-31) — plus verified pitfalls from CarSah's first-ever iOS build (2026-08-13, BL-100). Where a step comes from live experience and not the official guide, it is marked [LIVE].
0. Prerequisites (hard requirements — check BEFORE anything)
| Requirement | Check command | Why |
|---|---|---|
| macOS device | uname — must be Darwin |
Xcode only runs on macOS |
| Xcode installed | xcodebuild -version |
Required to build/release |
| iOS platform SDK installed | xcodebuild -showsdks | grep -i iphoneos |
[LIVE] CarSah's first pitfall: the simulator build failed with "missing iOS 26.5 platform" — the iOS SDK was NOT installed in Xcode. Fix: Xcode → Settings → Components → install the iOS platform (or xcodebuild -downloadPlatform iOS). Without it, NO iOS build (device or simulator) can even be attempted. |
| CocoaPods | pod --version |
iOS plugin dependencies |
| Apple Developer Program | https://developer.apple.com/programs/ |
Required to publish (99$/yr) |
| App Store Connect app record | Browser — appstoreconnect.apple.com | Register bundle ID + app record |
